Quetiapine Extended-release tablets should be administered once daily, preferably in the evening.

2.2 Recommended Dosing The recommended initial dose, titration, dose range and maximum quetiapine extended-release tablets dose for each approved indication is displayed in Table 1 below. After initial dosing, adjustments can be made upwards or downwards, if necessary, depending upon the clinical response and tolerability of the patient [see Clinical Studies ( 14.1 , 14.2 and 14.3 )]. Table 1: Recommended Dosing for Quetiapine Extended-release tablets Indication Initial Dose and Titration Recommended Dose Maximum Dose Schizophrenia- Adults Day 1: 300 mg/day Dose increases can be made at intervals as short as 1 day and in increments of up to 300 mg/day 400 to 800 mg/day 800 mg/day Schizophrenia-Adolescents (13 to 17 years) Day 1: 50 mg/day Day 2: 100 mg/day Day 3: 200 mg/day Day 4: 300 mg/day Day 5: 400 mg/day 400 to 800 mg/day 800 mg/day Schizophrenia Maintenance-Monotherapy-Adults Not applicable 400 to 800 mg/day 800 mg/day Bipolar I Disorder manic or mixed-Acute monotherapy or adjunct to lithium or divalproex-Adults Day 1: 300 mg/day Day 2: 600 mg/day Day 3: between 400 and 800 mg/day 400 to 800 mg/day 800 mg/day Bipolar I Disorder, manic -Acute monotherapy -Children and Adolescents (10 to 17 years) Day 1: 50 mg/day Day 2: 100 mg/day Day 3: 200 mg/day Day 4: 300 mg/day Day 5: 400 mg/day 400 to 600 mg/day 600 mg/day Bipolar Disorder, Depressive Episodes-Adults Day 1: 50 mg/day Day 2: 100 mg/day Day 3: 200 mg/day Day 4: 300 mg/day 300 mg/day 300 mg/day Bipolar I Disorder Maintenance- Adjunct to lithium or divalproex-Adults Not applicable 400 to 800 mg/day 800 mg/day Major Depressive Disorder- Adjunctive Therapy with Antidepressants-Adults Day 1: 50 mg/day Day 2: 50 mg/day Day 3: 150 mg/day 150 to 300 mg/day 300 mg/day Maintenance Treatment for Schizophrenia and Bipolar I Disorder Maintenance Treatment—Patients should be periodically reassessed to determine the need for maintenance treatment and the appropriate dose for such treatment [see Clinical Studies ( 14.1 , 14.2 )].

2.3 Dose Modifications in Elderly Patients Consideration should be given to a slower rate of dose titration and a lower target dose in the elderly and in patients who are debilitated or who have a predisposition to hypotensive reactions [see Use in Specific Populations ( 8.5 , 8.7 ), and Clinical Pharmacology (12.3) ]. When indicated, dose escalation should be performed with caution in these patients. Elderly patients should be started on quetiapine extended-release tablets 50 mg/day and the dose can be increased in increments of 50 mg/day depending on the clinical response and tolerability of the individual patient.

2.4 Dose Modifications in Hepatically Impaired Patients Patients with hepatic impairment should be started on quetiapine extended-release tablets 50 mg/day. The dose can be increased daily in increments of 50 mg/day to an effective dose, depending on the clinical response and tolerability of the patient.

2.5 Dose Modifications when used with CYP3A4 Inhibitors Quetiapine Extended-release tablets dose should be reduced to one-sixth of original dose when co-medicated with a potent CYP3A4 inhibitor (e.g., ketoconazole, itraconazole, indinavir, ritonavir, nefazodone, etc.). When the CYP3A4 inhibitor is discontinued, the dose of quetiapine extended-release tablets should be increased by 6-fold [see Clinical Pharmacology (12.3) and Drug Interactions (7.1 )].

2.6 Dose Modifications when used with CYP3A4 Inducers Quetiapine Extended-release tablets dose should be increased up to 5-fold of the original dose when used in combination with a chronic treatment (e.g., greater than 7 to 14 days) of a potent CYP3A4 inducer (e.g., phenytoin, carbamazepine, rifampin, avasimibe, St. John’s wort etc.). The dose should be titrated based on the clinical response and tolerance of the individual patient. When the CYP3A4 inducer is discontinued, the dose of quetiapine extended-release tablets should be reduced to the original level within 7 to 14 days [see Clinical Pharmacology (12.3) and Drug Interactions (7.1) ].

2.7 Re-initiation of Treatment in Patients Previously Discontinued Although there are no data to specifically address re-initiation of treatment, it is recommended that when restarting therapy of patients who have been off quetiapine extended-release tablets for more than one-week, the initial dosing schedule should be followed. When restarting patients who have been off quetiapine extended-release tablets for less than one-week, gradual dose escalation may not be required and the maintenance dose may be re-initiated.

2.8 Switching Patients from SEROQUEL Tablets to Quetiapine Extended-Release Tablets Patients who are currently being treated with SEROQUEL (immediate release formulation) may be switched to quetiapine extended-release tablets at the equivalent total daily dose taken once daily. Individual dosage adjustments may be necessary.

2.9 Switching from Antipsychotics There are no systematically collected data to specifically address switching patients from other antipsychotics to quetiapine extended-release tablets, or concerning concomitant administration with other antipsychotics. While immediate discontinuation of the previous antipsychotic treatment may be acceptable for some patients, more gradual discontinuation may be most appropriate for others. In all cases, the period of overlapping antipsychotic administration should be minimized. When switching patients from depot antipsychotics, if medically appropriate, initiate quetiapine extended-release tablets therapy in place of the next scheduled injection. The need for continuing existing extrapyramidal syndrome medication should be re-evaluated periodically.

5 WARNINGS AND PRECAUTIONS Cerebrovascular Adverse Reactions: Increased incidence of cerebrovascular adverse reactions (e.g., stroke, transient ischemic attack) has been seen in elderly patients with dementia-related psychoses treated with atypical antipsychotic drugs (5.3) Neuroleptic Malignant Syndrome (NMS): Manage with immediate discontinuation and close monitoring (5.4) Metabolic Changes: Atypical antipsychotics have been associated with metabolic changes. These metabolic changes include hyperglycemia, dyslipidemia, and weight gain (5.5) Hyperglycemia and Diabetes Mellitus: Monitor patients for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Monitor glucose regularly in patients with diabetes or at risk for diabetes Dyslipidemia: Undesirable alterations have been observed in patients treated with atypical antipsychotics. Appropriate clinical monitoring is recommended, including fasting blood lipid testing at the beginning of, and periodically, during treatment Weight Gain: Gain in body weight has been observed; clinical monitoring of weight is recommended Tardive Dyskinesia: Discontinue if clinically appropriate (5.6) Hypotension: Use with caution in patients with known cardiovascular or cerebrovascular disease (5.7) Increased Blood Pressure in Children and Adolescents: Monitor blood pressure at the beginning of, and periodically during treatment in children and adolescents (5.9) Leukopenia, Neutropenia, and Agranulocytosis: Monitor complete blood count frequently during the first few months of treatment in patients with a pre-existing low white cell count or a history of leukopenia/neutropenia and discontinue quetiapine extended-release tablets at the first sign of a decline in WBC in absence of other causative factors (5.10) Cataracts: Lens changes have been observed in patients during long-term quetiapine treatment. Lens examination is recommended when starting treatment and at 6-month intervals during chronic treatment (5.11) Anticholinergic (antimuscarinic) Effects: Use with caution with other anticholinergic drugs and in patients with urinary retention, prostatic hypertrophy or constipation (5.20).

5.1 Increased Mortality in Elderly Patients with Dementia-Related Psychosis Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analysis of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group. Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear. Quetiapine Extended-release tablets are not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning].

5.2 Suicidal Thoughts and Behaviors in Adolescents and Young Adults Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18 to 24) with major depressive disorder (MDD) and other psychiatric disorders. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older. The pooled analyses of placebo-controlled trials in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short-term trials of 9 antidepressant drugs in over 4,400 patients. The pooled analyses of placebo-controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short-term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients. There was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger patients for almost all drugs studied. There were differences in absolute risk of suicidality across the different indications, with the highest incidence in MDD. The risk differences (drug vs. placebo), however, were relatively stable within age strata and across indications. These risk differences (drug-placebo difference in the number of cases of suicidality per 1000 patients treated) are provided in Table 2. Table 2: Drug-Placebo Difference in Number of Cases of Suicidality per 1000 Patients Treated Age Range Drug-Placebo Difference in Number of Cases of Suicidality per 1000 Patients Treated Increases Compared to Placebo <18 14 additional cases 18 to 24 5 additional cases Decreases Compared to Placebo 25 to 64 1 fewer case ≥65 6 fewer cases No suicides occurred in any of the pediatric trials. There were suicides in the adult trials, but the number was not sufficient to reach any conclusion about drug effect on suicide. It is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with depression that the use of antidepressants can delay the recurrence of depression. All patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality, and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decreases. The following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, and mania, have been reported in adult and pediatric patients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and non-psychiatric. Although a causal link between the emergence of such symptoms and either the worsening of depression and/or the emergence of suicidal impulses has not been established, there is concern that such symptoms may represent precursors to emerging suicidality. Consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patient's presenting symptoms. Families and caregivers of patients being treated with antidepressants for major depressive disorder or other indications, both psychiatric and non-psychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to healthcare providers. Such monitoring should include daily observation by families and caregivers. Prescriptions for quetiapine extended-release tablets should be written for the smallest quantity of tablets consistent with good patient management, in order to reduce the risk of overdose. Screening Patients for Bipolar Disorder: A major depressive episode may be the initial presentation of bipolar disorder. It is generally believed (though not established in controlled trials) that treating such an episode with an antidepressant alone may increase the likelihood of precipitation of a mixed/manic episode in patients at risk for bipolar disorder. Whether any of the symptoms described above represent such a conversion is unknown. However, prior to initiating treatment with an antidepressant, including quetiapine extended-release tablets, patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression.

5.3 Cerebrovascular Adverse Reactions, Including Stroke, in Elderly Patients with Dementia-Related Psychosis In placebo-controlled trials with risperidone, aripiprazole, and olanzapine in elderly subjects with dementia, there was a higher incidence of cerebrovascular adverse reactions (cerebrovascular accidents and transient ischemic attacks), including fatalities, compared to placebo-treated subjects. Quetiapine Extended-release tablets are not approved for the treatment of patients with dementia-related psychosis [see Boxed Warning and Warnings and Precautions (5.1) ].

5.4 Neuroleptic Malignant Syndrome (NMS) A potentially fatal symptom complex sometimes referred to as Neuroleptic Malignant Syndrome (NMS) has been reported in association with administration of antipsychotic drugs, including quetiapine. Rare cases of NMS have been reported with quetiapine. Clinical manifestations of NMS are hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia). Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. The diagnostic evaluation of patients with this syndrome is complicated. In arriving at a diagnosis, it is important to exclude cases where the clinical presentation includes both serious medical illness (e.g., pneumonia, systemic infection, etc.) and untreated or inadequately treated extrapyramidal signs and symptoms (EPS). Other important considerations in the differential diagnosis include central anticholinergic toxicity, heat stroke, drug fever, and primary central nervous system (CNS) pathology. The management of NMS should include: 1) immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy; 2) intensive symptomatic treatment and medical monitoring; and 3) treatment of any concomitant serious medical problems for which specific treatments are available. There is no general agreement about specific pharmacological treatment regimens for NMS. If a patient requires antipsychotic drug treatment after recovery from NMS, the potential reintroduction of drug therapy should be carefully considered. The patient should be carefully monitored since recurrences of NMS have been reported.

5.5 Metabolic Changes Atypical antipsychotic drugs have been associated with metabolic changes that include hyperglycemia/diabetes mellitus, dyslipidemia, and body weight gain. While all of the drugs in the class have been shown to produce some metabolic changes, each drug has its own specific risk profile. In some patients, a worsening of more than one of the metabolic parameters of weight, blood glucose, and lipids was observed in clinical studies. Changes in these metabolic profiles should be managed as clinically appropriate. Hyperglycemia and Diabetes Mellitus Hyperglycemia, in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, has been reported in patients treated with atypical antipsychotics, including quetiapine. Assessment of the relationship between atypical antipsychotic use and glucose abnormalities is complicated by the possibility of an increased background risk of diabetes mellitus in patients with schizophrenia and the increasing incidence of diabetes mellitus in the general population. Given these confounders, the relationship between atypical antipsychotic use and hyperglycemia-related adverse reactions is not completely understood. However, epidemiological studies suggest an increased risk of hyperglycemia-related adverse reactions in patients treated with the atypical antipsychotics. Precise risk estimates for hyperglycemia-related adverse reactions in patients treated with atypical antipsychotics are not available. Patients with an established diagnosis of diabetes mellitus who are started on atypical antipsychotics should be monitored regularly for worsening of glucose control. Patients with risk factors for diabetes mellitus (e.g., obesity, family history of diabetes) who are starting treatment with atypical antipsychotics should undergo fasting blood glucose testing at the beginning of treatment and periodically during treatment. Any patient treated with atypical antipsychotics should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical antipsychotics should undergo fasting blood glucose testing. In some cases, hyperglycemia has resolved when the atypical antipsychotic was discontinued; however, some patients required continuation of anti-diabetic treatment despite discontinuation of the suspect drug. Adults: Table 3: Fasting Glucose-Proportion of Patients Shifting to ≥126 mg/dL in Short-Term (≤12 weeks) Placebo-Controlled Studies 1 Laboratory Analyte Category Change (At Least Once) from Baseline Treatment Arm N Patients n (%) Fasting Glucose Normal to High (<100 mg/dL to ≥126 mg/dL) Quetiapine 2907 71 (2.4%) Placebo 1346 19 (1.4%) Borderline to High (≥100 mg/dL and <126 mg/dL to ≥126 mg/dL) Quetiapine 572 67 (11.7%) Placebo 279 33 (11.8%) 1 Includes SEROQUEL and quetiapine extended-release tablets data. In a 24-week trial (active-controlled, 115 patients treated with SEROQUEL) designed to evaluate glycemic status with oral glucose tolerance testing of all patients, at week 24 the incidence of a post-glucose challenge glucose level ≥200 mg/dL was 1.7% and the incidence of fasting blood glucose level ≥126 mg/dL was 2.6%. The mean change in fasting glucose from baseline was 3.2 mg/dL and mean change in 2 hour glucose from baseline was -1.8 mg/dL for quetiapine. In 2 long-term placebo-controlled randomized withdrawal clinical trials for bipolar I disorder maintenance, mean exposure of 213 days for SEROQUEL (646 patients) and 152 days for placebo (680 patients), the mean change in glucose from baseline was +5.0 mg/dL for quetiapine and –0.05 mg/dL for placebo. The exposure-adjusted rate of any increased blood glucose level (≥126 mg/dL) for patients more than 8 hours since a meal (however, some patients may not have been precluded from calorie intake from fluids during fasting period) was 18.0 per 100 patient years for SEROQUEL (10.7% of patients; n=556) and 9.5 for placebo per 100 patient years (4.6% of patients; n=581). Table 4 shows the percentage of patients with shifts in blood glucose to ≥126 mg/dL from normal baseline in MDD adjunct therapy trials by dose.

In a placebo-controlled quetiapine extended-release tablets monotherapy study (8 weeks duration) of children and adolescent patients (10 to 17 years of age) with bipolar depression, in which efficacy was not established, the mean change in fasting glucose levels for quetiapine extended-release tablets (n=60) compared to placebo (n=62) was 1.8 mg/dL versus 1.6 mg/dL. In this study, there were no patients in the quetiapine extended-release tablets or placebo-treated groups with a baseline normal fasting glucose level (<100 mg/dL) that had an increase in blood glucose level ≥126 mg/dL. There was one patient in the quetiapine extended-release tablets group with a baseline borderline fasting glucose level (≥100 mg/dL and <126 mg/dL) who had an increase in blood glucose level of >126 mg/dL compared to zero patients in the placebo group. In a placebo-controlled SEROQUEL monotherapy study of adolescent patients (13 to 17 years of age) with schizophrenia (6 weeks duration), the mean change in fasting glucose levels for SEROQUEL (n=138) compared to placebo (n=67) was –0.75 mg/dL versus –1.70 mg/dL. In a placebo-controlled SEROQUEL monotherapy study of children and adolescent patients (10 to 17 years of age) with bipolar mania (3 weeks duration), the mean change in fasting glucose level for SEROQUEL (n=170) compared to placebo (n=81) was 3.62 mg/dL versus –1.17 mg/dL. No patient in either study with a baseline normal fasting glucose level (<100 mg/dL) or a baseline borderline fasting glucose level (≥100 mg/dL and <126 mg/dL) had a blood glucose level of ≥126 mg/dL.

In a clinical trial for quetiapine extended-release tablets in children and adolescents (10 to 17 years of age) with bipolar depression, in which efficacy was not established, the percentage of patients with weight gain ≥7% of body weight at any time was 15% (14/92) for quetiapine extended-release tablets vs. 10% (10/100) for placebo. The mean change in body weight was 1.4 kg in the quetiapine extended-release tablets group vs. 0.6 kg in the placebo group. Weight gain was greater in patients 10 to 12 years of age compared to patients 13 to 17 years of age. The percentage of patients 10 to 12 years of age with weight gain ≥7% at any time was 28% (7/25) for quetiapine extended-release tablets vs. 0% (0/28) for placebo. The percentage of patients 13 to 17 years of age with weight gain ≥7% at any time was 10.4% (7/67) for quetiapine extended-release tablets vs. 13.9% (10/72) for placebo. Table 10 shows the percentage of children and adolescents with weight gain ≥7% of body weight in clinical trials with SEROQUEL in adolescents (13 to 17 years) with schizophrenia and in children and adolescents (10 to 17 years) with bipolar mania.

In an open-label study that enrolled patients from the above two pediatric trials, 63% of patients (241/380) completed 26 weeks of therapy with SEROQUEL. After 26 weeks of treatment, the mean increase in body weight was 4.4 kg. Forty-five percent of the patients gained ≥ 7% of their body weight, not adjusted for normal growth. In order to adjust for normal growth over 26 weeks, an increase of at least 0.5 standard deviation from baseline in BMI was used as a measure of a clinically significant change; 18.3% of patients on SEROQUEL met this criterion after 26 weeks of treatment. When treating pediatric patients with SEROQUEL for any indication, weight gain should be assessed against that expected for normal growth.

5.6 Tardive Dyskinesia A syndrome of potentially irreversible, involuntary, dyskinetic movements may develop in patients treated with antipsychotic drugs including quetiapine. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown.A syndrome of potentially irreversible, involuntary, dyskinetic movements may develop in patients treated with antipsychotic drugs including quetiapine. Although the prevalence of the syndrome appears to be highest among the elderly, especially elderly women, it is impossible to rely upon prevalence estimates to predict, at the inception of antipsychotic treatment, which patients are likely to develop the syndrome. Whether antipsychotic drug products differ in their potential to cause tardive dyskinesia is unknown. The risk of developing tardive dyskinesia and the likelihood that it will become irreversible are believed to increase as the duration of treatment and the total cumulative dose of antipsychotic drugs administered to the patient increase. However, the syndrome can develop, although much less commonly, after relatively brief …

6.1 Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Adults The information below is derived from a clinical trial database for quetiapine extended-release tablets consisting of approximately 3400 patients exposed to quetiapine extended-release tablets for the treatment of Schizophrenia, Bipolar Disorder, and Major Depressive Disorder in placebo-controlled trials. This experience corresponds to approximately 1020.1 patient-years. Adverse reactions were assessed by collecting adverse reactions, results of physical examinations, vital signs, body weights, laboratory analyses, and ECG results. The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, an adverse reaction of the type listed. Adverse Reactions Associated with Discontinuation of Treatment in Short-Term, Placebo-Controlled Trials Schizophrenia: There were no adverse reactions leading to discontinuation that occurred at an incidence of ≥2% for quetiapine extended-release tablets in schizophrenia trials. Bipolar I Disorder, Manic or Mixed Episodes: There were no adverse reactions leading to discontinuation that occurred at an incidence of ≥2% for quetiapine extended-release tablets in the bipolar mania trial. Bipolar Disorder, Depressive Episode: In a single clinical trial in patients with bipolar depression, 14% (19/137) of patients on quetiapine extended-release tablets discontinued due to an adverse reaction compared to 4% (5/140) on placebo. Somnolence 1 was the only adverse reaction leading to discontinuation that occurred at an incidence of ≥2% in quetiapine extended-release tablets in the bipolar depression trial. MDD, Adjunctive Therapy: In adjunctive therapy clinical trials in patients with MDD, 12.1% (76/627) of patients on quetiapine extended-release tablets discontinued due to adverse reaction compared to 1.9% (6/309) on placebo. Somnolence was the only adverse reaction leading to discontinuation that occurred at an incidence of ≥2% in quetiapine extended-release tablets in MDD trials. Commonly Observed Adverse Reactions in Short-Term, Placebo-Controlled Trials: In short-term placebo-controlled studies for schizophrenia the most commonly observed adverse reactions associated with the use of quetiapine extended-release tablets (incidence of 5% or greater) and observed at a rate on quetiapine extended-release tablets at least twice that of placebo were somnolence (25%), dry mouth (12%), dizziness (10%), and dyspepsia (5%). Adverse Reactions Occurring at an Incidence of 2% or More among Quetiapine Extended-Release Tablets Treated Patients in Short-Term, Placebo-Controlled Trials. Table 12 enumerates the incidence, rounded to the nearest percent, of adverse reactions that occurred during acute therapy of schizophrenia (up to 6 weeks) in 2% or more in patients treated with quetiapine extended-release tablets (doses ranging from 300 to 800 mg/day) where the incidence in patients treated with quetiapine extended-release tablets were greater than the incidence in placebo-treated patients.

Adverse Reactions in clinical trials with quetiapine and not listed elsewhere in the label Pyrexia, nightmares, peripheral edema, dyspnea, palpitations, rhinitis, eosinophilia, hypersensitivity, elevations in gamma-GT levels, and elevations in serum creatine phosphokinase (not associated with NMS), somnambulism (and other related events), hypothermia, decreased platelets, galactorrhea, bradycardia (which may occur at or near initiation of treatment and be associated with hypotension and/ or syncope), and priapism. Extrapyramidal Symptoms (EPS): Dystonia Class Effect : Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups. Four methods were used to measure EPS: (1) Simpson-Angus total score (mean change from baseline) which evaluates Parkinsonism and akathisia, (2) Barnes Akathisia Rating Scale (BARS) Global Assessment Score, (3) incidence of spontaneous complaints of EPS (akathisia, akinesia, cogwheel rigidity, extrapyramidal syndrome, hypertonia, hypokinesia, neck rigidity, and tremor), and (4) use of anticholinergic medications to treat EPS. Adults : In placebo-controlled clinical trials with quetiapine, utilizing doses up to 800 mg per day, the incidence of any adverse reactions related to EPS ranged from 8% to 11% for quetiapine and 4% to 11% for placebo. In three-arm placebo-controlled clinical trials for the treatment of schizophrenia, utilizing doses between 300 mg and 800 mg of quetiapine extended-release tablets, the incidence of any adverse reactions related to EPS was 8% for quetiapine extended-release tablets and 8% for SEROQUEL (without evidence of being dose related), and 5% in the placebo group. In these studies, the incidence of the individual adverse reactions (akathisia, extrapyramidal disorder, tremor, dyskinesia, dystonia, restlessness, and muscle rigidity) was generally low and did not exceed 3% for any treatment group. At the end of treatment, the mean change from baseline in SAS total score and BARS Global Assessment score was similar across the treatment groups. The use of concomitant anticholinergic medications was infrequent and similar across the treatment groups. The incidence of extrapyramidal symptoms was consistent with that seen with the profile of SEROQUEL in schizophrenia patients. In Tables 16 to 19, dystonic event included nuchal rigidity, hypertonia, dystonia, muscle rigidity, oculogyration; parkinsonism included cogwheel rigidity, tremor, drooling, hypokinesia; akathisia included akathisia, psychomotor agitation; dyskinetic event included tardive dyskinesia, dyskinesia, choreoathetosis; and other extrapyramidal event included restlessness, extrapyramidal disorder, movement disorder.

This database includes 677 adolescents (13 to 17 years old) exposed to SEROQUEL for the treatment of schizophrenia and 393 children and adolescents (10 to 17 years old) exposed to SEROQUEL for the treatment of acute bipolar mania. Adverse Reactions Associated with Discontinuation of Treatment in Short-Term, Placebo-Controlled Trials Schizophrenia:The incidence of discontinuation due to adverse reactions for quetiapine-treated and placebo-treated patients was 8.2% and 2.7%, respectively. The adverse reaction leading to discontinuation in 2% or more of patients on quetiapine and at a greater incidence than placebo was somnolence (2.7% and 0% for placebo). Bipolar I Mania:The incidence of discontinuation due to adverse reactions for quetiapine-treated and placebo-treated patients was 11.4% and 4.4%, respectively. The adverse reactions leading to discontinuation in 2% or more of patients on SEROQUEL and at a greater incidence than placebo were somnolence (4.1% vs. 1.1%) and fatigue (2.1% vs. 0%). Commonly Observed Adverse Reactions in Short-Term, Placebo-Controlled Trials: In an acute (8-week) quetiapine extended-release tablets trial in children and adolescents (10 to 17 years of age) with bipolar depression, in which efficacy was not established, the most commonly observed adverse reactions associated with the use of quetiapine extended-release tablets (incidence of 5% or greater and at least twice that for placebo) were: dizziness 7%, diarrhea 5%, fatigue 5% and nausea 5%. In therapy for schizophrenia (up to 6 weeks), the most commonly observed adverse reactions associated with the use of quetiapine in adolescents (incidence of 5% or greater and quetiapine incidence at least twice that for placebo) were somnolence (34%), dizziness (12%), dry mouth (7%), tachycardia (7%). In bipolar mania therapy (up to 3 weeks) the most commonly observed adverse reactions associated with the use of quetiapine in children and adolescents (incidence of 5% or greater and quetiapine incidence at least twice that for placebo) were somnolence (53%), dizziness (18%), fatigue (11%), increased appetite (9%), nausea (8%), vomiting (8%), tachycardia (7%), dry mouth (7%), and weight increased (6%). Adverse Reactions Occurring at an Incidence of ≥2% among SEROQUEL Treated Patients in Short-Term, Placebo-Controlled Trials Schizophrenia (Adolescents, 13 to 17 years old) The following findings were based on a 6-week placebo-controlled trial in which quetiapine was administered in either doses of 400 or 800 mg/day. Table 20 enumerates the incidence, rounded to the nearest percent, of adverse reactions that occurred during therapy (up to 6 weeks) of schizophrenia in 2% or more of patients treated with SEROQUEL (doses of 400 or 800 mg/day) where the incidence in patients treated with SEROQUEL was greater than the incidence in placebo-treated patients. Adverse reactions that were potentially dose-related with higher frequency in the 800 mg group compared to the 400 mg group included dizziness (8% vs. 15%), dry mouth (4% vs. 10%), and tachycardia (6% vs. 11%).

Bipolar I Mania (Children and Adolescents 10 to 17 years old) The following findings were based on a 3-week placebo-controlled trial in which quetiapine was administered in either doses of 400 or 600 mg/day. Table 21 enumerates the incidence, rounded to the nearest percent, of adverse reactions that occurred during therapy (up to 3 weeks) of bipolar mania in 2% or more of patients treated with SEROQUEL (doses of 400 or 600 mg/day) where the incidence in patients treated with SEROQUEL was greater than the incidence in placebo-treated patients. Adverse reactions that were potentially dose-related with higher frequency in the 600 mg group compared to the 400 mg group included somnolence (50% vs. 57%), nausea (6% vs. 10%), and tachycardia (6% vs. 9%).

Extrapyramidal Symptoms: Safety and effectiveness of quetiapine extended-release tablets are supported by studies of SEROQUEL in children and adolescent patients 10 to 17 years of age [see Clinical Studies ( 14.1 and 14.2 )]. In a short-term placebo-controlled quetiapine extended-release tablets monotherapy trial in children and adolescent patients (10 to 17 years of age) with bipolar depression (8-week duration), in which efficacy was not established, the aggregated incidence of extrapyramidal symptoms was 1.1% (1/92) for quetiapine extended-release tablets and 0% (0/100) for placebo. In a short-term placebo-controlled SEROQUEL monotherapy trial in adolescent patients (13 to 17 years of age) with schizophrenia (6-week duration), the aggregated incidence of extrapyramidal symptoms was 12.9% (19/147) for SEROQUEL and 5.3% (4/75) for placebo, though the incidence of the individual adverse reactions (e.g., akathisia, tremor, extrapyramidal disorder, hypokinesia, restlessness, psychomotor hyperactivity, muscle rigidity, dyskinesia) did not exceed 4.1% in any treatment group. In a short-term placebo-controlled SEROQUEL monotherapy trial in children and adolescent patients (10 to 17 years of age) with bipolar mania (3-week duration), the aggregated incidence of extrapyramidal symptoms was 3.6% (7/193) for SEROQUEL and 1.1% (1/90) for placebo. In Tables 22 and 23, dystonic events included nuchal rigidity, hypertonia, dystonia, and muscle rigidity; parkinsonism included cogwheel rigidity and tremor; akathisia included akathisia only; dyskinetic event included tardive dyskinesia, dyskinesia and choreoathetosis; and other extrapyramidal event included restlessness and extrapyramidal disorder.

Laboratory, ECG and vital sign changes observed in clinical studies Laboratory Changes: Neutrophil Counts Adults: In three-arm quetiapine extended-release tablets placebo-controlled monotherapy clinical trials, among patients with a baseline neutrophil count ≥1.5 x 10 9 /L, the incidence of at least one occurrence of neutrophil count <1.5 x 10 9 /L was 1.5% in patients treated with quetiapine extended-release tablets and 1.5% for SEROQUEL, compared to 0.8% in placebo-treated patients. In placebo-controlled monotherapy clinical trials involving 3368 patients on quetiapine and 1515 on placebo, the incidence of at least one occurrence of neutrophil count <1.0 x 10 9 /L among patients with a normal baseline neutrophil count and at least one available follow up laboratory measurement was 0.3% (10/2967) in patients treated with quetiapine, compared to 0.1% (2/1349) in patients treated with placebo [see Warnings and Precautions (5.10) ]. Transaminase Elevations Adults: Asymptomatic, transient and reversible elevations in serum transaminases (primarily ALT) have been reported. The proportions of adult patients with transaminase elevations of >3 times the upper limits of the normal reference range in a pool of placebo-controlled trials ranged between 1% and 2% for quetiapine extended-release tablets compared to 2% for placebo. In schizophrenia trials in adults, the proportions of patients with transaminase elevations of >3 times the upper limits of the normal reference range in a pool of 3-to 6-week placebo-controlled trials were approximately 6% (29/483) for SEROQUEL compared to 1% (3/194) for placebo. These hepatic enzyme elevations usually occurred within the first 3 weeks of drug treatment and promptly returned to pre-study levels with ongoing treatment with quetiapine. Decreased Hemoglobin Adults: In short-term placebo-controlled trials, decreases in hemoglobin to ≤13 g/dL males, ≤12 g/dL females on at least one occasion occurred in 8.3% (594/7155) of quetiapine-treated patients compared to 6.2% (219/3536) of patients treated with placebo. In a database of controlled and uncontrolled clinical trials, decreases in hemoglobin to ≤13 g/dL males, ≤12 g/dL females on at least one occasion occurred in 11% (2277/20729) of quetiapine-treated patients. Interference with Urine Drug Screens There have been literature reports suggesting false positive results in urine enzyme immunoassays for methadone and tricyclic antidepressants in patients who have taken quetiapine. Caution should be exercised in the interpretation of positive urine drug screen results for these drugs, and confirmation by alternative analytical technique (e.g., chromatographic methods) should be considered.

Pregnancy: May cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure. (8.1)

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including quetiapine extended-release tablets, during pregnancy. Healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or online at http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/ Risk Summary Neonates exposed to antipsychotic drugs, including quetiapine extended-release tablets, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see Clinical Considerations) . Overall available data from published epidemiologic studies of pregnant women exposed to quetiapine have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data) . There are risks to the mother associated with untreated schizophrenia, bipolar I, or major depressive disorder, and with exposure to antipsychotics, including, quetiapine extended-release tablets during pregnancy (see Clinical Considerations) . In animal studies, embryo-fetal toxicity occurred including delays in skeletal ossification at approximately 1 and 2 times the maximum recommended human dose (MRHD) of 800 mg/day in both rats and rabbits, and an increased incidence of carpal/tarsal flexure (minor soft tissue anomaly) in rabbit fetuses at approximately 2 times the MRHD. In addition, fetal weights were decreased in both species. Maternal toxicity (observed as decreased body weights and/or death) occurred at 2 times the MRHD in rats and approximately 1 to 2 times the MRHD in rabbits. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-associated maternal and/or fetal risk There is a risk to the mother from untreated schizophrenia, or bipolar I disorder, including increased risk of relapse, hospitalization, and suicide. Schizophrenia and bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors. A prospective, longitudinal study followed 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. The women who discontinued antidepressants during pregnancy were more likely to experience a relapse of major depression than women who continued antidepressants. Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. Fetal/neonatal adverse reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including quetiapine extended-release tablets, during the third trimester of pregnancy. These symptoms varied in severity. Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Data Human Data Published data from observational studies, birth registries, and case reports on the use of atypical antipsychotics during pregnancy do not report a clear association with antipsychotics and major birth defects. A retrospective cohort study from a Medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk of major birth defects. Animal Data When pregnant rats and rabbits were exposed to quetiapine during organogenesis, there was no teratogenic effect in fetuses. Doses were 25, 50 and 200 mg/kg in rats and 25, 50 and 100 mg/kg in rabbits which are approximately 0.3, 0.6 and 2-times (rats) and 0.6, 1 and 2-times (rabbits) the MRHD, for schizophrenia of 800 mg/day based on mg/m 2 body surface area. However, there was evidence of embryo-fetal toxicity, including delays in skeletal ossification at approximately 1 and 2 times the MRHD of 800 mg/day in both rats and rabbits and an increased incidence of carpal/tarsal flexure (minor soft tissue anomaly) in rabbit fetuses at approximately 2 times the MRHD. In addition, fetal weights were decreased in both species. Maternal toxicity (observed as decreased body weights and/or death) occurred at 2 times the MRHD in rats and at approximately 1 to 2 times the MRHD (all doses tested) in rabbits. In a peri/postnatal reproductive study in rats, no drug-related effects were observed when pregnant dams were treated with quetiapine at doses 0.01, 0.1, and 0.2 times the MRHD of 800 mg/day based on mg/m 2 body surface area. However, in a preliminary peri/postnatal study, there were increases in fetal and pup death, and decreases in mean litter weight at 3 times the MRHD.

8.2 Lactation Risk Summary Limited data from published literature report the presence of quetiapine in human breast milk at relative infant dose of <1% of the maternal weight-adjusted dosage. There are no consistent adverse events that have been reported in infants exposed to quetiapine through breast milk. There is no information on the effects of quetiapine on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for quetiapine extended-release tablets and any potential adverse effects on the breastfed child from quetiapine extended-release tablets or from the mother’s underlying condition.

8.3 Females and Males of Reproductive Potential Infertility Females Based on the pharmacologic action of quetiapine (D2 antagonism), treatment with quetiapine extended-release tablets may result in an increase in serum prolactin levels, which may lead to a reversible reduction in fertility in females of reproductive potential [see Warnings and Precautions (5.15) ] .

8.4 Pediatric Use Safety and effectiveness of quetiapine extended-release tablets are supported by studies of SEROQUEL for schizophrenia in adolescent patients 13 to 17 years of age and in bipolar mania in children and adolescent patients 10 to 17 years of age [see Clinical Studies ( 14.1 and 14.2 )]. In general, the adverse reactions observed in children and adolescents during the clinical trials with SEROQUEL were similar to those in the adult population with few exceptions. Increases in systolic and diastolic blood pressure occurred in children and adolescents and did not occur in adults. Orthostatic hypotension occurred more frequently in adults (4 to 7%) compared to children and adolescents (<1%) [see Warnings and Precautions (5.7) and Adverse Reactions (6.1) ]. Bipolar Depression The effectiveness of quetiapine extended-release tablets for the treatment of bipolar depression in patients under the age of 18 years has not been established. One 8-week trial was conducted to evaluate the safety and efficacy of quetiapine extended-release tablets in the treatment of bipolar depression in pediatric patients 10 to 17 years of age. The primary objective of the study was to evaluate whether quetiapine extended-release tablets at a dose of 150 to 300 mg/day demonstrated superior efficacy (as measured by change in CDRS-R total score from baseline to end of 8 weeks) compared to placebo in children and adolescents 10 to 17 years of age with bipolar depression. A total of 193 patients with bipolar depression were randomized to placebo or quetiapine extended-release tablets. The primary results of this study did not show a difference between quetiapine extended-release tablets and placebo in decreasing depression symptoms in children and adolescents with bipolar disorder. In this study, patients treated with quetiapine extended-release tablets exhibited metabolic changes, weight gain, increases in blood pressure and increases in heart rate [see Warnings and Precautions ( 5.5 , 5.9 ) and Adverse Reactions (6.1) ]. Some differences in the pharmacokinetics of quetiapine were noted between children/adolescents (10 to 17 years of age) and adults. When adjusted for weight, the AUC and Cmax of quetiapine were 41% and 39% lower, respectively, in children and adolescents compared to adults. The pharmacokinetics of the active metabolite, norquetiapine, were similar between children/adolescents and adults after adjusting for weight [see Clinical Pharmacology (12.3) ]. Schizophrenia The efficacy and safety of quetiapine extended-release tablets in the treatment of schizophrenia in adolescents aged 13 to 17 years is supported by one 6-week, double-blind, placebo-controlled trial with SEROQUEL [see Indications and Usage (1.1) , Dosage and Administration (2.2) , Adverse Reactions (6.1) , and Clinical Studies (14.1) ]. Safety and effectiveness of quetiapine extended-release tablets in pediatric patients less than 13 years of age with schizophrenia have not been established. The safety and effectiveness of quetiapine extended-release tablets in the maintenance treatment of schizophrenia has not been established in patients less than 18 years of age. Bipolar Mania The efficacy and safety of quetiapine extended-release tablets in the treatment of bipolar mania in children and adolescents ages 10 to 17 years is supported by one 3-week, double-blind, placebo controlled trial with SEROQUEL [see Indications and Usage (1.2) , Dosage and Administration (2.2) , Adverse Reactions (6.1) , and Clinical Studies (14.2) ]. Safety and effectiveness of quetiapine extended-release tablets in pediatric patients less than 10 years of age with bipolar mania have not been established. The safety and effectiveness of quetiapine extended-release tablets in the maintenance treatment of bipolar disorder has not been established in patients less than 18 years of age.

8.5 Geriatric Use Sixty-eight patients in clinical studies with quetiapine extended-release tablets were 65 years of age or over. In general, there was no indication of any different tolerability of quetiapine extended-release tablets in the elderly compared to younger adults. Nevertheless, the presence of factors that might decrease pharmacokinetic clearance, increase the pharmacodynamic response to quetiapine extended-release tablets, or cause poorer tolerance or orthostasis, should lead to consideration of a lower starting dose, slower titration, and careful monitoring during the initial dosing period in the elderly. The mean plasma clearance of quetiapine was reduced by 30% to 50% in elderly patients when compared to younger patients [see Dosage and Administration (2.3) and Clinical Pharmacology (12.3) ].

8.6 Renal Impairment Clinical experience with quetiapine extended-release tablets in patients with renal impairment is limited [see Clinical Pharmacology (12.3) ].

8.7 Hepatic Impairment Since quetiapine is extensively metabolized by the liver, higher plasma levels are expected in patients with hepatic impairment. In this population, a low starting dose of 50 mg/day is recommended and the dose may be increased in increments of 50 mg/day [see Dosage and Administration (2.4) and Clinical Pharmacology (12.3) ].

However, in a preliminary peri/postnatal study, there were increases in fetal and pup death, and decreases in mean litter weight at 3 times the MRHD.

12.1 Mechanism of Action The mechanism of action of quetiapine in the listed indications is unclear. However, the efficacy of quetiapine in these indications could be mediated through a combination of dopamine type 2 (D 2 ) and serotonin type 2A (5HT 2A ) antagonism. The active metabolite, N-desalkyl quetiapine (norquetiapine), has similar activity at D 2 , but greater activity at 5HT 2A receptors, than the parent drug (quetiapine).

12.2 Pharmacodynamics Quetiapine and its metabolite norquetiapine have affinity for multiple neurotransmitter receptors with norquetiapine binding with higher affinity than quetiapine in general. The K i values for quetiapine and norquetiapine at the dopamine D 1 are 428/99.8 nM, at D 2 626/489nM, at serotonin 5HT 1A 1040/191 nM at 5HT 2A 38/2.9 nM, at histamine H 1 4.4/1.1 nM, at muscarinic M 1 1086/38.3 nM, and at adrenergic α 1 b 14.6/46.4 nM and, at α2 receptors 617/1290 nM, respectively. Quetiapine and norquetiapine lack appreciable affinity to the benzodiazepine receptors. Effect on QT Interval In clinical trials quetiapine was not associated with a persistent increase in QT intervals. However, the QT effect was not systematically evaluated in a thorough QT study. In post marketing experience, there were cases reported of QT prolongation in patients who overdosed on quetiapine [see Overdosage (10.1) ] , in patients with concomitant illness, and in patients taking medicines known to cause electrolyte imbalance or increase QT interval.

12.3 Pharmacokinetics Adults Following multiple dosing of quetiapine up to a total daily dose of 800 mg, administered in divided doses, the plasma concentration of quetiapine and norquetiapine, the major active metabolite of quetiapine, were proportional to the total daily dose. Accumulation is predictable upon multiple dosing. Steady-state mean C max and AUC of norquetiapine are about 21 to 27% and 46 to 56%, respectively, of that observed for quetiapine. Elimination of quetiapine is mainly via hepatic metabolism. The mean-terminal half-life is approximately 7 hours for quetiapine and approximately 12 hours for norquetiapine within the clinical dose range. Steady-state concentrations are expected to be achieved within two days of dosing. Quetiapine Extended-release tablets are unlikely to interfere with the metabolism of drugs metabolized by cytochrome P450 enzymes. Children and Adolescents At steady-state, the pharmacokinetics of the parent compound, in children and adolescents (10 to 17 years of age), were similar to adults. However, when adjusted for dose and weight, AUC and C max of the parent compound were 41% and 39% lower, respectively, in children and adolescents than in adults. For the active metabolite, norquetiapine, AUC and C max were 45% and 31% higher, respectively, in children and adolescents than in adults. When adjusted for dose and weight, the pharmacokinetics of the metabolite, norquetiapine, was similar between children and adolescents and adults [see Use in Specific Populations (8.4) ]. Absorption Quetiapine fumarate reaches peak plasma concentrations approximately 6 hours following administration. Quetiapine Extended-release tablets dosed once daily at steady state has comparable bioavailability to an equivalent total daily dose of SEROQUEL administered in divided doses, twice daily. A high-fat meal (approximately 800 to 1000 calories) was found to produce statistically significant increases in the quetiapine extended-release tablets C max and AUC of 44% to 52% and 20% to 22%, respectively, for the 50 mg and 300 mg tablets. In comparison, a light meal (approximately 300 calories) had no significant effect on the C max or AUC of quetiapine. It is recommended that quetiapine extended-release tablets be taken without food or with a light meal [see Dosage and Administration (2.1) ]. Distribution Quetiapine is widely distributed throughout the body with an apparent volume of distribution of 10±4 L/kg. It is 83% bound to plasma proteins at therapeutic concentrations. In vitro , quetiapine did not affect the binding of warfarin or diazepam to human serum albumin. In turn, neither warfarin nor diazepam altered the binding of quetiapine. Metabolism and Elimination Following a single oral dose of 14 C-quetiapine, less than 1% of the administered dose was excreted as unchanged drug, indicating that quetiapine is highly metabolized. Approximately 73% and 20% of the dose was recovered in the urine and feces, respectively. The average dose fraction of free quetiapine and its major active metabolite is <5% excreted in the urine. Quetiapine is extensively metabolized by the liver. The major metabolic pathways are sulfoxidation to the sulfoxide metabolite and oxidation to the parent acid metabolite; both metabolites are pharmacologically inactive. In vitro studies using human liver microsomes revealed that the cytochrome P450 3A4 isoenzyme is involved in the metabolism of quetiapine to its major, but inactive, sulfoxide metabolite and in the metabolism of its active metabolite norquetiapine. Age Oral clearance of quetiapine was reduced by 40% in elderly patients (≥65 years, n=9) compared to young patients (n=12), and dosing adjustment may be necessary [see Dosage and Administration (2.3) ]. Gender There is no gender effect on the pharmacokinetics of quetiapine. Race There is no race effect on the pharmacokinetics of quetiapine. Smoking Smoking has no effect on the oral clearance of quetiapine. Renal Insufficiency Patients with severe renal impairment (CL cr =10 to 30 mL/min/1.73m 2 , n=8) had a 25% lower mean oral clearance than normal subjects (CL cr >80 mL/min/1.73m 2 , n=8), but plasma quetiapine concentrations in the subjects with renal insufficiency were within the range of concentrations seen in normal subjects receiving the same dose. Dosage adjustment is therefore not needed in these patients [see Use in Specific Populations (8.6) ]. Hepatic Insufficiency Hepatically impaired patients (n=8) had a 30% lower mean oral clearance of quetiapine than normal subjects. In 2 of the 8 hepatically impaired patients, AUC and C max were 3 times higher than those observed typically in healthy subjects. Since quetiapine is extensively metabolized by the liver, higher plasma levels are expected in the hepatically impaired population, and dosage adjustment may be needed [see Dosage and Administration (2.4) and Use in Specific Populations (8.7) ]. Drug-Drug Interaction Studies The in vivo assessments of effect of other drugs on the pharmacokinetics of quetiapine are summarized in Table 24 [see Dosage and Administration ( 2.5 , 2.6 ) and Drug Interactions (7.1) ]. Table 24: The Effect of Other Drugs on the Pharmacokinetics of Quetiapine Coadministered Drug Dose Schedules Effect on Quetiapine Pharmacokinetics Coadministered Drug Quetiapine Phenytoin 100 mg three times daily 250 mg three times daily 5-fold increase in oral clearance Divalproex 500 mg twice daily 150 mg twice daily 17% increase mean max plasma concentration at steady state. No effect on absorption or mean oral clearance Thioridazine 200 mg twice daily 300 mg twice daily 65% increase in oral clearance Cimetidine 400 mg three times daily for 4 days 150 mg three times daily 20% decrease in mean oral clearance Ketoconazole (potent CYP 3A4 inhibitor) 200 mg once daily for 4 days 25 mg single dose 84% decrease in oral clearance resulting in a 6.2-fold increase in AUC of quetiapine Fluoxetine 60 mg once daily 300 mg twice daily No change in steady state PK Imipramine 75 mg twice daily 300 mg twice daily No change in steady state PK Haloperidol 7.5 mg twice daily 300 mg twice daily No change in steady state PK Risperidone 3 mg twice daily 300 mg twice daily No change in steady state PK In vitro enzyme inhibition data suggest that quetiapine and 9 of its metabolites would have little inhibitory effect on in vivo metabolism mediated by cytochromes CYP 1A2, 2C9, 2C19, 2D6, and 3A4. Quetiapine at doses of 750 mg/day did not affect the single dose pharmacokinetics of antipyrine, lithium or lorazepam (Table 25) [see Drug Interactions (7.2) ]. Table 25: The Effect of Quetiapine on the Pharmacokinetics of Other Drugs Coadministered Drug Dose Schedules Effect on Other Drugs Pharmacokinetics Coadministered Drug Quetiapine Lorazepam 2 mg, single dose 250 mg three times daily Oral clearance of lorazepam reduced by 20% Divalproex 500 mg twice daily 150 mg twice daily C max and AUC of free valproic acid at steady-state was decreased by 10 to 12% Lithium Up to 2400 mg/day given in twice daily doses 250 mg three times daily No effect on steady-state pharmacokinetics of lithium Antipyrine 1 g, single dose 250 mg three times daily No effect on clearance of antipyrine or urinary recovery of its metabolites

Adults Following multiple dosing of quetiapine up to a total daily dose of 800 mg, administered in divided doses, the plasma concentration of quetiapine and norquetiapine, the major active metabolite of quetiapine, were proportional to the total daily dose. Accumulation is predictable upon multiple dosing. Steady-state mean C max and AUC of norquetiapine are about 21 to 27% and 46 to 56%, respectively, of that observed for quetiapine. Elimination of quetiapine is mainly via hepatic metabolism. The mean-terminal half-life is approximately 7 hours for quetiapine and approximately 12 hours for norquetiapine within the clinical dose range. Steady-state concentrations are expected to be achieved within two days of dosing. Quetiapine Extended-release tablets are unlikely to interfere with the metabolism of drugs metabolized by cytochrome P450 enzymes. Children and Adolescents At steady-state, the pharmacokinetics of the parent compound, in children and adolescents (10 to 17 years of age), were similar to adults. However, when adjusted for dose and weight, AUC and C max of the parent compound were 41% and 39% lower, respectively, in children and adolescents than in adults. For the active metabolite, norquetiapine, AUC and C max were 45% and 31% higher, respectively, in children and adolescents than in adults. When adjusted for dose and weight, the pharmacokinetics of the metabolite, norquetiapine, was similar between children and adolescents and adults [see Use in Specific Populations (8.4) ]. Absorption Quetiapine fumarate reaches peak plasma concentrations approximately 6 hours following administration. Quetiapine Extended-release tablets dosed once daily at steady state has comparable bioavailability to an equivalent total daily dose of SEROQUEL administered in divided doses, twice daily. A high-fat meal (approximately 800 to 1000 calories) was found to produce statistically significant increases in the quetiapine extended-release tablets C max and AUC of 44% to 52% and 20% to 22%, respectively, for the 50 mg and 300 mg tablets. In comparison, a light meal (approximately 300 calories) had no significant effect on the C max or AUC of quetiapine. It is recommended that quetiapine extended-release tablets be taken without food or with a light meal [see Dosage and Administration (2.1) ]. Distribution Quetiapine is widely distributed throughout the body with an apparent volume of distribution of 10±4 L/kg. It is 83% bound to plasma proteins at therapeutic concentrations. In vitro , quetiapine did not affect the binding of warfarin or diazepam to human serum albumin. In turn, neither warfarin nor diazepam altered the binding of quetiapine. Metabolism and Elimination Following a single oral dose of 14 C-quetiapine, less than 1% of the administered dose was excreted as unchanged drug, indicating that quetiapine is highly metabolized. Approximately 73% and 20% of the dose was recovered in the urine and feces, respectively. The average dose fraction of free quetiapine and its major active metabolite is <5% excreted in the urine. Quetiapine is extensively metabolized by the liver. The major metabolic pathways are sulfoxidation to the sulfoxide metabolite and oxidation to the parent acid metabolite; both metabolites are pharmacologically inactive. In vitro studies using human liver microsomes revealed that the cytochrome P450 3A4 isoenzyme is involved in the metabolism of quetiapine to its major, but inactive, sulfoxide metabolite and in the metabolism of its active metabolite norquetiapine. Age Oral clearance of quetiapine was reduced by 40% in elderly patients (≥65 years, n=9) compared to young patients (n=12), and dosing adjustment may be necessary [see Dosage and Administration (2.3) ]. Gender There is no gender effect on the pharmacokinetics of quetiapine. Race There is no race effect on the pharmacokinetics of quetiapine. Smoking Smoking has no effect on the oral clearance of quetiapine. Renal Insufficiency Patients with severe renal impairment (CL cr =10 to 30 mL/min/1.73m 2 , n=8) had a 25% lower mean oral clearance than normal subjects (CL cr >80 mL/min/1.73m 2 , n=8), but plasma quetiapine concentrations in the subjects with renal insufficiency were within the range of concentrations seen in normal subjects receiving the same dose. Dosage adjustment is therefore not needed in these patients [see Use in Specific Populations (8.6) ]. Hepatic Insufficiency Hepatically impaired patients (n=8) had a 30% lower mean oral clearance of quetiapine than normal subjects. In 2 of the 8 hepatically impaired patients, AUC and C max were 3 times higher than those observed typically in healthy subjects. Since quetiapine is extensively metabolized by the liver, higher plasma levels are expected in the hepatically impaired population, and dosage adjustment may be needed [see Dosage and Administration (2.4) and Use in Specific Populations (8.7) ].

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide). Patients should be advised of the following issues and asked to alert their prescriber if these occur while taking quetiapine extended-release tablets. Increased Mortality in Elderly Patients with Dementia-Related Psychosis Patients and caregivers should be advised that elderly patients with dementia-related psychoses treated with atypical antipsychotic drugs are at increased risk of death compared with placebo. Quetiapine Extended-release tablets are not approved for elderly patients with dementia-related psychosis [see Warnings and Precautions (5.1) ]. Suicidal Thoughts and Behaviors Patients, their families, and their caregivers should be encouraged to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, mania, other unusual changes in behavior, worsening of depression, and suicidal ideation, especially early during antidepressant treatment and when the dose is adjusted up or down. Families and caregivers of patients should be advised to look for the emergence of such symptoms on a day-to-day basis, since changes may be abrupt. Such symptoms should be reported to the patient's prescriber or health professional, especially if they are severe, abrupt in onset, or were not part of the patient's presenting symptoms. Symptoms such as these may be associated with an increased risk for suicidal thinking and behavior and indicate a need for very close monitoring and possibly changes in the medication [see Warnings and Precautions (5.2) ]. Neuroleptic Malignant Syndrome (NMS) Patients should be advised to report to their physician any signs or symptoms that may be related to NMS. These may include muscle stiffness and high fever [see Warnings and Precautions (5.4) ]. Hyperglycemia and Diabetes Mellitus Patients should be aware of the symptoms of hyperglycemia (high blood sugar) and diabetes mellitus. Patients who are diagnosed with diabetes, those with risk factors for diabetes, or those that develop these symptoms during treatment should have their blood glucose monitored at the beginning of and periodically during treatment [see Warnings and Precautions (5.5) ]. Hyperlipidemia Patients should be advised that elevations in total cholesterol, LDL-cholesterol and triglycerides and decreases in HDL-cholesterol may occur. Patients should have their lipid profile monitored at the beginning of and periodically during treatment [see Warnings and Precautions (5.5) ]. Weight Gain Patients should be advised that they may experience weight gain. Patients should have their weight monitored regularly [see Warnings and Precautions (5.5) ]. Orthostatic Hypotension Patients should be advised of the risk of orthostatic hypotension (symptoms include feeling dizzy or lightheaded upon standing, which may lead to falls) especially during the period of initial dose titration, and also at times of re-initiating treatment or increases in dose [see Warnings and Precautions (5.7) ]. Increased Blood Pressure in Children and Adolescents Children and adolescent patients should have their blood pressure measured at the beginning of, and periodically during, treatment [see Warnings and Precautions (5.9) ]. Leukopenia/Neutropenia Patients with a pre-existing low WBC or a history of drug induced leukopenia/neutropenia should be advised that they should have their CBC monitored while taking quetiapine. Patients should be advised to talk to their doctor as soon as possible if they have a fever, flu-like symptoms, sore throat, or any other infection as this could be a result of a very low WBC, which may require quetiapine to be stopped and/or treatment to be given [see Warnings and Precautions (5.10) ]. Interference with Cognitive and Motor Performance Patients should be advised of the risk of somnolence or sedation (which may lead to falls), especially during the period of initial dose titration. Patients should be cautioned about performing any activity requiring mental alertness, such as operating a motor vehicle (including automobiles) or operating machinery, until they are reasonably certain quetiapine therapy does not affect them adversely. [see Warnings and Precautions (5.16) ]. Heat Exposure and Dehydration Patients should be advised regarding appropriate care in avoiding overheating and dehydration [see Warnings and Precautions (5.17) ]. Concomitant Medication As with other medications, patients should be advised to notify their physicians if they are taking, or plan to take, any prescription or over-the-counter drugs [see Drug Interactions (7.1) ]. Pregnancy Advise pregnant women to notify their healthcare provider if they become pregnant or intend to become pregnant during treatment with quetiapine extended-release tablets. Advise patients that quetiapine extended-release tablets may cause extrapyramidal and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder) in a neonate. Advise patients that there is a pregnancy registry that monitors pregnancy outcomes in women exposed to quetiapine extended-release tablets during pregnancy [see Use in Specific Populations ( 8.1 )]. Infertility Advise females of reproductive potential that quetiapine extended-release tablets may impair fertility due to an increase in serum prolactin levels. The effects on fertility are reversible [see Use in Specific Populations ( 8.3 )] . Need for Comprehensive Treatment Program Quetiapine extended-release tablets are indicated as an integral part of a total treatment program for adolescents with schizophrenia and pediatric bipolar disorder that may include other measures (psychological, educational, and social). Effectiveness and safety of quetiapine extended-release tablets have not been established in pediatric patients less than 13 years of age for schizophrenia or less than 10 years of age for bipolar mania. Appropriate educational placement is essential and psychosocial intervention is often helpful. The decision to prescribe atypical antipsychotic medication will depend upon the physician’s assessment of the chronicity and severity of the patient’s symptoms. [see Indications and Usage (1.4) ].
