Why two NDCs? The FDA registers this code as 29300-312-16 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 29300-0312-16. Same drug, same package — only the format differs.

Quetiapine is used to treat schizophrenia (a mental illness that affects how a person thinks, feels and behaves), bipolar disorder (a disease that causes depression, mania, and other abnormal moods) and major depressive disorder. Quetiapine is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🗺️ Medicaid utilization & spend

📍 This exact package only: Medicaid data is reported per full 11-digit NDC — labeler, product and pack size — so every number here is for 29300-0312-16, not the drug overall. Other pack sizes report separately.
💊 Pharmacy benefit only: These are Medicaid outpatient pharmacy claims, billed by NDC. They exclude the medical benefit — clinic- or hospital-administered drugs billed under HCPCS J-codes — so drugs used mostly that way (e.g. Avastin, Lucentis, Keytruda) can look low or missing here. That’s expected, not an error.
📅 Q1 2025 – Q4 2025 · 4 quarters of data
ⓘ The newest quarter is usually incomplete when first published; states restate recent quarters in later CMS releases, so the latest figures typically revise upward. State coverage-policy changes can also shift quarter-to-quarter totals.

🎯 Indications and Usage ~2 min read

1 INDICATIONS AND USAGE Quetiapine is an atypical antipsychotic indicated for the treatment of: Schizophrenia ( 1.1 ) Bipolar I disorder, manic, or mixed episodes ( 1.2 ) Bipolar disorder, depressive episodes ( 1.2 ) Major depressive disorder, adjunctive therapy with antidepressants ( 1.3 )

1.1Schizophrenia Quetiapine extended-release tablets are indicated for the treatment of schizophrenia. The efficacy of quetiapine extended-release tablets in schizophrenia was established in one 6-week and one maintenance trial in adults with schizophrenia. Efficacy was supported by three 6-week trials in adults with schizophrenia and one 6-week trial in adolescents with schizophrenia (13-17 years) treated with quetiapine tablets [see Clinical Studies (14.1) ] .

1.2Bipolar Disorder Quetiapine extended-release tablets are indicated for the acute treatment of manic or mixed episodes associated with bipolar I disorder, both as monotherapy and as an adjunct to lithium or divalproex. The efficacy of quetiapine extended-release tablets in manic or mixed episodes of bipolar I disorder was established in one 3-week trial in adults with manic or mixed episodes associated with bipolar I disorder. Efficacy was supported by two 12-week monotherapy trials and one 3-week adjunctive trial in adults with manic episodes associated with bipolar I disorder as well as one 3-week monotherapy trial in children and adolescents (10 - 17 years) with manic episodes associated with bipolar I disorder treated with quetiapine tablets [see Clinical Studies (14.2) ] .

Quetiapine extended-release tablets are indicated for the acute treatment of depressive episodes associated with bipolar disorder. The efficacy of quetiapine extended-release tablets was established in one 8-week trial in adults with bipolar I or II disorder and supported by two 8 week trials in adults with bipolar I or II disorder treated with quetiapine tablets [see Clinical Studies (14.2) ] . Quetiapine extended-release tablets are indicated for the maintenance treatment of bipolar I disorder, as an adjunct to lithium or divalproex.

Efficacy was extrapolated from two maintenance trials in adults with bipolar I disorder treated with quetiapine tablets. The effectiveness of monotherapy for the maintenance treatment of bipolar I disorder has not been systematically evaluated in controlled clinical trials [see Clinical Studies (14.2) ] .

1.3Adjunctive Treatment of Major Depressive Disorder (MDD) Quetiapine extended-release tablets are indicated for use as adjunctive therapy to antidepressants for the treatment of MDD. The efficacy of quetiapine extended-release tablets as adjunctive therapy to antidepressants in MDD was established in two 6-week trials in adults with MDD who had an inadequate response to antidepressant treatment [see Clinical Studies (14.3) ] .

1.4Special Considerations in Treating Pediatric Schizophrenia and Bipolar I Disorder Pediatric schizophrenia and bipolar I disorder are serious mental disorders, however, diagnosis can be challenging. For pediatric schizophrenia, symptom profiles can be variable, and for bipolar I disorder, patients may have variable patterns of periodicity of manic or mixed symptoms. It is recommended that medication therapy for pediatric schizophrenia and bipolar I disorder be initiated only after a thorough diagnostic evaluation has been performed and careful consideration given to the risks associated with medication treatment.

Medication treatment for both pediatric schizophrenia and bipolar I disorder is indicated as part of a total treatment program that often includes psychological, educational and social interventions.

⚠️ Warnings and Cautions ~3 min read

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 )

5.1Increased 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 ] .

5.2Suicidal 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 st…

6.1Clinical 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 was the only adverse reaction leading to discontinuation that occurred at an incidence of ≥2% in quetiapine extended-release tablets in the bipolar depression t…

7 DRUG INTERACTIONS Concomitant use of strong CYP3A4 inhibitors: Reduce quetiapine dose to one-sixth when coadministered with strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) ( 2.5 , 7.1 , 12.3 ) Concomitant use of strong CYP3A4 inducers: Increase quetiapine dose up to 5 fold when used in combination with a chronic treatment (more than 7-14 days) of potent CYP3A4 inducers (e.g., phenytoin, rifampin, St. John's wort) ( 2.6 , 7.1 , 12.3 ) Discontinuation of strong CYP3A4 inducers: Reduce quetiapine dose by 5-fold within 7-14 days of discontinuation of CYP3A4 inducers ( 2.6 , 7.1 , 12.3 )

7.1Effect of Other Drugs on Quetiapine The risks of using quetiapine extended-release tablets in combination with other drugs have not been extensively evaluated in systematic studies. Given the primary CNS effects of quetiapine extended-release tablets, caution should be used when it is taken in combination with other centrally acting drugs. Quetiapine potentiated the cognitive and motor effects of alcohol in a clinical trial in subjects with selected psychotic disorders, and alcoholic beverages should be limited while taking quetiapine.

Quetiapine exposure is increased by the prototype CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, indinavir, ritonavir, nefazodone, etc.) and decreased by the prototype of CYP3A4 inducers (e.g., phenytoin, carbamazepine, rifampin, avasimibe, St. John's wort etc.). Dose adjustment of quetiapine will be necessary if it is co-administered with potent CYP3A4 inducers or inhibitors.

CYP3A4 inhibitors: Coadministration of ketoconazole, a potent inhibitor of cytochrome CYP3A4, resulted in significant increase in quetiapine exposure. The dose should be reduced to one-sixth of the original dose in patients coadministered with a strong CYP3A4 inhibitor [see Dosage and Administration (2.5) and Clinical Pharmacology (12.3) ] . CYP3A4 inducers: Coadministration of quetiapine and phenytoin, a CYP3A4 inducer increased the mean oral clearance of quetiapine by 5 fold.

Increased doses of quetiapine extended-release tablets up to 5-fold may be required to maintain control of symptoms of schizophrenia in patients receiving quetiapine and phenytoin, or other known potent CYP3A4 inducers [see Dosage and Administration (2.6) and Clinical Pharmacology (12.3) ] . When the CYP3A4 inducer is discontinued, the dose of quetiapine extended-release tablets should be reduced to the original level within 7-14 days [see Dosage and Administration (2.6) ] . Anticholinergic Drugs: Concomitant treatment with quetiapine and other drugs with anticholinergic activity can increase the risk for severe gastrointestinal adverse reactions related to hypomotility.

Quetiapine tablets should be used with caution in patients receiving medications having anticholinergic (antimuscarinic) effects [see Warnings and Precautions (5.20) ]. The potential effects of several concomitant medications on quetiapine pharmacokinetics were studied [see Clinical Pharmacology (12.3) ] .

7.2Effect of Quetiapine on Other Drugs Because of its potential for inducing hypotension, quetiapine extended-release tablets may enhance the effects of certain antihypertensive agents. Quetiapine extended-release tablets may antagonize the effects of levodopa and dopamine agonists. There are no clinically relevant pharmacokinetic interactions of quetiapine tablets on other drugs based on the CYP pathway.

Quetiapine tablets and its metabolites are non-inhibitors of major metabolizing CYP's (1A2, 2C9, 2C19, 2D6, and 3A4).

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

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including quetiapine, 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, 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 1-2 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, 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.

🧒 Pediatric Use ~3 min read

8.4Pediatric Use Safety and effectiveness of quetiapine extended-release tablets is supported by studies of quetiapine tablets for schizophrenia in adolescent patients 13 - 17 years of age and in bipolar mania in children and adolescent patients 10 - 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 quetiapine tablets 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 (4-7%) 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 - 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 - 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 - 17 years of age) and adults. When adjusted for weight, the AUC and C max 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 - 17 years is supported by one 6-week, double-blind, placebo-controlled trial with quetiapine tablets [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 10-17 years is supported by one 3-week, double-blind, placebo-controlled trial with quetiapine tablets [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.

🧓 Geriatric Use 117 words

8.5Geriatric 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) ] .

🆘 Overdosage ~1 min read

10 OVERDOSAGE

10.1Human Experience In clinical trials, survival has been reported in acute overdoses of up to 30 grams of quetiapine. Most patients who overdosed experienced no adverse reactions or recovered fully from the reported events. Death has been reported in a clinical trial following an overdose of 13.6 grams of quetiapine alone.

In general, reported signs and symptoms were those resulting from an exaggeration of the drug's known pharmacological effects, i.e., drowsiness, sedation, tachycardia, hypotension, and anticholinergic toxicity including coma and delirium. Patients with pre-existing severe cardiovascular disease may be at an increased risk of the effects of overdose [see Warnings and Precautions (5.12) ] . One case, involving an estimated overdose of 9600 mg, was associated with hypokalemia and first degree heart block.

In post-marketing experience, there were cases reported of QT prolongation with overdose.

10.2Management of Overdosage Establish and maintain an airway and ensure adequate oxygenation and ventilation. Cardiovascular monitoring should commence immediately and should include continuous electrocardiographic monitoring to detect possible arrhythmias. Appropriate supportive measures are the mainstay of management.

For the most up-to-date information on the management of quetiapine extended-release tablets overdosage, contact a certified Regional Poison Control Center (1-800-222-1222). Quetiapine extended-release tablets overdose may lead to gastric bezoar formation and appropriate diagnostic imaging is recommended to further guide patient management. Routine gastric lavage may not be effective in the removal of the bezoar due to gum like sticky consistency of the mass.

Endoscopic pharmacobezoar removal has been performed successfully.

12 CLINICAL PHARMACOLOGY

12.1Mechanism 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).

12.2Pharmacodynamics Quetiapine and its metabolite norquetiapine have affinity for multiple neurotransmitter receptors with norquetiapine binding with higher affinity than quetiapine in general. The Ki 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 α 2 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.

12.3Pharmacokinetics 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 21-27% and 46-56%, 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 (10-17 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 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 quetiapine tablets 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…
