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.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Clozapine — the program that covers self-administered drugs. 5 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Clozapine. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

🚨 Boxed Warning ~2 min read

WARNING: SEVERE NEUTROPENIA; ORTHOSTATIC HYPOTENSION, BRADYCARDIA, AND SYNCOPE; SEIZURE; MYOCARDITIS, PERICARDITIS, AND CARDIOMYOPATHY; INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS Severe Neutropenia Clozapine Orally Disintegrating Tablets (Clozapine ODT) has caused severe neutropenia which is associated with an increased risk of serious and potentially fatal infections. Prior to initiating Clozapine ODT treatment, obtain baseline ANC(s). Clozapine ODT initiation is not recommended in patients with a baseline ANC less than 1500/μL (less than 1000/μL for those with Benign Ethnic Neutropenia (also known as Duffy-null associated neutrophil count)).

See recommendations for dosage modifications based on ANC levels during Clozapine ODT treatment [see Dosage and Administration (2.4 , 2.5) ]. Consider a hematology consultation before initiating Clozapine ODT or during Clozapine ODT treatment [see Warnings and Precautions (5.1) ]. Orthostatic Hypotension, Bradycardia, Syncope Orthostatic hypotension, bradycardia, syncope, and cardiac arrest have occurred with clozapine treatment.

The risk is highest during the initial titration period, particularly with rapid dose escalation. These reactions can occur with the first dose, with doses as low as 12.5 mg per day, or when restarting patients who have had even a brief interruption in treatment with Clozapine ODT . Initiate treatment at 12.5 mg once or twice daily; titrate slowly; and use divided dosages to minimize risk.

Use Clozapine ODT cautiously in patients with cardiovascular or cerebrovascular disease or conditions predisposing to hypotension (e.g., dehydration, use of antihypertensive medications) [see Dosage and Administration (2.3 , and 2.6) , Warnings and Precautions (5.2) ]. Seizures Seizures have occurred with clozapine treatment. The risk is dose-related.

Initiate treatment at 12.5 mg, titrate gradually, and use divided dosing. Use caution when administering Clozapine ODT to patients with a history of seizures or other predisposing risk factors for seizure (CNS pathology, medications that lower the seizure threshold, alcohol abuse). Caution patients about engaging in any activity where sudden loss of consciousness could cause serious risk to themselves or others [see Dosage and Administration (2.3) , Warnings and Precautions (5.4) ].

Myocarditis, Pericarditis, Cardiomyopathy and Mitral Valve Incompetence Fatal myocarditis and cardiomyopathy have occurred with clozapine treatment. Discontinue Clozapine ODT and obtain a cardiac evaluation upon suspicion of these reactions. Generally, patients with clozapine-related myocarditis or cardiomyopathy should not be rechallenged with Clozapine ODT .

Consider the possibility of myocarditis, pericarditis, or cardiomyopathy if chest pain, tachycardia, palpitations, dyspnea, fever, flu-like symptoms, hypotension, or ECG changes occur [see Warnings and Precautions (5.5) ]. 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. Clozapine ODT is not approved for use in patients with dementia-related psychosis [see Warnings and Precautions (5.6) ].

WARNING: SEVERE NEUTROPENIA; ORTHOSTATIC HYPOTENSION, BRADYCARDIA, AND SYNCOPE; SEIZURE; MYOCARDITIS, PERICARDITIS, AND CARDIOMYOPATHY; INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS See full prescribing information for complete boxed warning . Severe Neutropenia: Clozapine has caused severe neutropenia, which is associated with an increased risk of serious and fatal infections. Prior to initiating Clozapine Orally Disintegrating Tablets (Clozapine ODT) treatment, obtain baseline ANC(s).

🎯 Indications and Usage ~1 min read

1 INDICATIONS AND USAGE Clozapine orally disintegrating tablets (Clozapine ODT) is an atypical antipsychotic indicated for: Treatment of severely ill patients with schizophrenia who fail to respond adequately to standard antipsychotic treatment. Because of the risks of severe neutropenia and of seizure associated with its use, Clozapine ODT should be used only in patients who have failed to respond adequately to standard antipsychotic treatment ( 1.1 ) Reducing the risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder who are judged to be at chronic risk for re-experiencing suicidal behavior ( 1.2 )

1.1Treatment-resistant Schizophrenia Clozapine Orally Disintegrating Tablets (Clozapine ODT) are indicated for the treatment of severely ill patients with schizophrenia who fail to respond adequately to standard antipsychotic treatment. Because of the risks of severe neutropenia and of seizure associated with their use, Clozapine ODT should be used only in patients who have failed to respond adequately to standard antipsychotic treatment [see Warnings and Precautions (5.1 , 5.4) ]. The effectiveness of Clozapine ODT in treatment-resistant schizophrenia was demonstrated in a 6-week, randomized, double-blind, active-controlled study comparing Clozapine ODT and chlorpromazine in patients who had failed other antipsychotics [see Clinical Studies (14.1) ].

1.2Reduction in the Risk of Recurrent Suicidal Behavior in Schizophrenia or Schizoaffective Disorder Clozapine ODT is indicated for reducing the risk of recurrent suicidal behavior in patients with schizophrenia or schizoaffective disorder who are judged to be at chronic risk for re-­experiencing suicidal behavior, based on history and recent clinical state. Suicidal behavior refers to actions by a patient that put him/herself at risk for death. The effectiveness of Clozapine ODT in reducing the risk of recurrent suicidal behavior was demonstrated over a two-year treatment period in the InterSePT™ trial [see Clinical Studies (14.2) ] .

⏱️ Dosage and Administration ~3 min read

2 DOSAGE AND ADMINISTRATION Recommended starting oral dosage is 12.5 mg once daily or twice daily. ( 2.2 ) If well-tolerated, increase the total daily dosage in increments of 25 mg to 50 mg per day at target dosage of 150 mg to 225 mg twice per day by the end of two weeks ( 2.2 ) Subsequently may increase the dosage in increments up to 100 mg, once or twice weekly. ( 2.2 ) Maximum daily dosage is 450 mg twice daily.

( 2.2 ) Administer with or without food. Clozapine ODT may be allowed to disintegrate or chewed, and may be taken with or without water. See additional administration instructions in full prescribing information ( 2.2 ).

See dosage modification based on ANC results ( 2.3 , 2.4 ) See recommendations for discontinuing Clozapine ODT treatment ( 2.5 ), restarting Clozapine ODT after interrupting dosing ( 2.6 ), dosage modifications for drug interactions ( 2.7 ), dosage recommendations in patients with renal or hepatic impairment and CYP2D6 poor metabolizers ( 2.8 ) in the full prescribing information. Tablets rapidly disintegrate after placement in the mouth and may be chewed if desired. No water is needed ( 2.3 ).

2.1Absolute Neutrophil Count Testing Prior to Clozapine ODT Initiation Prior to initiating Clozapine ODT treatment, obtain a baseline absolute neutrophil count (ANC). Clozapine ODT initiation is not recommended in patients with an ANC less than 1500/μL [see Warnings and Precautions (5.1) ]. For patients with documented Benign Ethnic Neutropenia (BEN) (also known as Duffy-null associated neutrophil count)), obtain at least two baseline ANC levels.

Clozapine ODT initiation is not recommended in patients with BEN with an ANC less than 1000/μL [see Warnings and Precautions (5.1) ]. For dosage modifications based on ANC results, see Dosage and Administration (2.4 , 2.5) .

2.2Recommended Dosage and Administration Recommended Dosage To reduce the risk of orthostatic hypotension, bradycardia, and syncope, the recommended starting dosage is much lower than the target dosage [see Warnings and Precautions (5.3) ]. The recommended starting oral dosage of Clozapine ODT is 12.5 mg once or twice daily. If well-tolerated, increase the total daily dose in increments of 25 mg to 50 mg per day to achieve a target dosage of 150 mg to 225 mg twice per day by the end of two weeks.

Subsequently, may increase the dosage in increments of up to 100 mg once weekly or twice weekly. The maximum recommended Clozapine ODT oral dosage is 450 mg twice daily. Administration Instructions Clozapine ODT can be taken with or without food, may be allowed to disintegrate or chewed, and may be taken with or without water [see Clinical Pharmacology (12.3) ].

Just prior to use, peel the foil from the blister and gently remove the orally disintegrating tablet (ODT). Do not push the ODT through the foil, because this could damage the ODT. After removing Clozapine ODT from the blister pack or bottle, immediately place in the mouth.

2.3Dosage Modifications Based on ANC Results Table 1 provides recommended Clozapine ODT dosage modifications based on ANC results [see Warnings and Precautions (5.1) ]. For dosage modifications based on ANC results for patients with Benign Ethnic Neutropenia (BEN) (also known as Duffy-null associated neutrophil count), see Table 2 [see Dosage and Administration (2.5) ].

⚠️ Warnings and Cautions ~3 min read

5 WARNINGS AND PRECAUTIONS Severe neutropenia: See Boxed Warning ( 5.1 ) Gastrointestinal Hypomotility with Severe Complications : Severe gastrointestinal adverse reactions have occurred with the use of clozapine. If constipation is identified, close monitoring and prompt treatment is advised. ( 5.7 ) Eosinophilia : Assess for organ involvement (e.g., myocarditis, pancreatitis, hepatitis, colitis, nephritis).

Discontinue if these occur. ( 5.8 ) QT Interval Prolongation : Can be fatal. Consider additional risk factors for prolonged QT interval (disorders and drugs).

( 5.9 ) Metabolic Changes : Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk. These metabolic changes include ( 5.10 ): Hyperglycemia and Diabetes Mellitus: Monitor 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 in lipids have occurred in patients treated with atypical antipsychotics. Weight Gain: Significant weight gain has occurred. Monitor weight gain.

Neuroleptic Malignant Syndrome (NMS) : Immediately discontinue and monitor closely. Assess for co-morbid conditions. ( 5.11 ) Hepatotoxicity: Can be fatal.

Monitor for hepatotoxicity. Discontinue treatment if hepatitis or transaminase elevations combined with other symptoms occur ( 5.12 ). Fever : Evaluate for infection and for neutropenia, NMS.

( 5.14 ) Pulmonary Embolism (PE) : Consider PE if respiratory distress, chest pain, or deep-vein thrombosis occurs. ( 5.15 ) Anticholinergic Toxicity : When possible, avoid use with other anticholinergic drugs and use with caution in patients with a current diagnosis or prior history of constipation, urinary retention, clinically significant prostatic hypertrophy, or other conditions in which anticholinergic effects can lead to significant adverse reactions. ( 5.15 , 7.1 ) Interference with Cognitive and Motor Performance : Advise caution when operating machinery, including automobiles.

( 5.16 )

5.1Severe Neutropenia Clozapine has caused severe neutropenia (absolute neutrophil count (ANC) less than 500/μL) [see Adverse Reactions (6.1 , 6.2) ] and is associated with an increased risk of serious and potentially fatal infections. Severe neutropenia occurred in a small percentage of clozapine-treated patients. The risk of severe neutropenia appears greatest during the first 18 weeks of Clozapine ODT treatment.

The mechanism by which Clozapine ODT causes neutropenia is unknown. Neutropenia is not dose-dependent. Consider a hematology consultation before initiating Clozapine ODT treatment or during treatment.

ANC Monitoring and Dosage Modifications Prior to initiating Clozapine ODT treatment, obtain a baseline ANC. Clozapine ODT initiation is not recommended in patients with a baseline ANC less than 1500/μL. Throughout VERZACLOZ treatment, regularly monitor ANC.

Table 1 provides recommendations for dosage modifications (dosage interruption and treatment discontinuation), based on ANC levels, during Clozapine ODT treatment and frequency of ANC monitoring [see Dosage and Administration (2.4) ] . ANC Monitoring and Dosage Modification in Patients with Benign Ethnic Neutropenia Patients with Benign Ethnic Neutropenia (BEN) (also known as Duffy-null associated neutrophil count) generally have lower baseline neutrophil counts but they are not at higher risk for developing infections, and they are not at increased risk for developing Clozapine ODT-induced neutropenia.

For patients with documented BEN, obtain at least two baseline ANC levels prior to Clozapine ODT initiation. Clozapine ODT initiation is not recommended in patients with BEN with an ANC less than 1000/μL. There are different ANC dosage modification recommendations in Clozapine ODT-treated patients with BEN due to their lower baseline ANC levels.

Table 2 provides recommendations on dosage modi…

7 DRUG INTERACTIONS Concomitant use of Strong CYP1A2 Inhibitors : Reduce Clozapine ODT dose to one third when coadministered with strong CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin, enoxacin). ( 2.7 , 7.1 ) Concomitant use of Strong CYP3A4 Inducers is not recommended. ( 2.7 , 7.1 ) Discontinuation of CYP1A2 or CYP3A4 Inducers : Consider reducing Clozapine ODT dose when CYP1A2 (e.g., tobacco smoke) or CYP3A4 inducers (e.g., carbamazepine) are discontinued.

( 2.7 , 7.1 ) Anticholinergic drugs: Concomitant use may increase the risk for anticholinergic toxicity. ( 5.7 , 5.15 , 7.1 )

7.1Potential for Other Drugs to Affect Clozapine ODT Clozapine is a substrate for many cytochrome P450 isozymes, in particular CYP1A2, CYP3A4, and CYP2D6. Use caution when administering Clozapine ODT concomitantly with drugs that are inducers or inhibitors of these enzymes. CYP1A2 Inhibitors Concomitant use of Clozapine ODT and CYP1A2 inhibitors can increase plasma levels of clozapine, potentially resulting in adverse reactions.

Reduce the Clozapine ODT dose to one third of the original dose when Clozapine ODT is coadministered with strong CYP1A2 inhibitors (e.g., fluvoxamine, ciprofloxacin, or enoxacin). The Clozapine ODT dose should be increased to the original dose when coadministration of strong CYP1A2 inhibitors is discontinued [see Dosage and Administration (2.7) , Clinical Pharmacology (12.3) ]. Moderate or weak CYP1A2 inhibitors include oral contraceptives and caffeine.

Monitor patients closely when Clozapine ODT is coadministered with these inhibitors. Consider reducing the Clozapine ODT dosage if necessary [see Dosage and Administration (2.7) ] . CYP2D6 and CYP3A4 Inhibitors Concomitant treatment with Clozapine ODT and CYP2D6 or CYP3A4 inhibitors (e.g., cimetidine, escitalopram, erythromycin, paroxetine, bupropion, fluoxetine, quinidine, duloxetine, terbinafine, or sertraline) can increase clozapine levels and lead to adverse reactions [see Clinical Pharmacology (12.3)] .

Use caution and monitor patients closely when using such inhibitors. Consider reducing the Clozapine ODT dose [see Dosage and Administration (2.7) ] . CYP1A2 and CYP3A4 Inducers Concomitant treatment with drugs that induce CYP1A2 or CYP3A4 can decrease the plasma concentration of clozapine, resulting in decreased effectiveness of Clozapine ODT.

Tobacco smoke is a moderate inducer of CYP1A2. Strong CYP3A4 inducers include carbamazepine, phenytoin, St. John’s wort, and rifampin.

It may be necessary to increase the Clozapine ODT dose if used concomitantly with inducers of these enzymes. However, concomitant use of Clozapine ODT and strong CYP3A4 inducers is not recommended [see Dosage and Administration (2.7) ]. Consider reducing the Clozapine ODT dosage when discontinuing coadministered enzyme inducers, because discontinuation of inducers can result in increased clozapine plasma levels and an increased risk of adverse reactions [see Dosage and Administration (2.7) ].

Anticholinergic Drugs Concomitant treatment with Clozapine ODT and other drugs with anticholinergic activity (e.g., benztropine, cyclobenzaprine, diphenhydramine) can increase the risk for anticholinergic toxicity and severe gastrointestinal adverse reactions related to hypomotility. Avoid concomitant use of Clozapine ODT with anticholinergic drugs when possible [see Warnings and Precautions (5.7 , 5.15) ] . Drugs that Cause QT Interval Prolongation Use caution when administering concomitant medications that prolong the QT interval or inhibit the metabolism of clozapine.

Drugs that cause QT prolongation include: specific antipsychotics (e.g., ziprasidone, iloperidone, chlorpromazine, thioridazine, mesoridazine, droperidol, and pimozide), specific antibiotics (e.g., erythromycin, gatifloxacin, moxifloxacin, sparfloxacin), Class 1A antiarrhythmics (e.g., quinidine, procainamide) or Class III antiarrhythmics (e.g., amiodarone, sotalol), and others (e.g., pentamidine, levomethadyl acetate, methadone, halofant…

8 USE IN SPECIFIC POPULATIONS Lactaton : Infants exposed to Clozapine ODT through breast milk should be monitored for excess sedation and neutropenia ( 8.2 )

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including CLOZARIL, during pregnancy. Healthcare providers are encouraged to advise patients to register by calling the National Pregnancy Registry for Atypical Antipsychotics at1-866-961-2388 or visiting http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/. Risk Summary Neonates exposed to antipsychotic drugs, including Clozapine ODT, during the third trimester are at risk for extrapyramidal and/or withdrawal symptoms following delivery ( see Clinical Considerations ).

Available data from published epidemiologic studies over decades of use with clozapine during pregnancy 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 and with exposure to antipsychotics, including Clozapine ODT, during pregnancy ( see Clinical Considerations ). In animal reproduction studies, no adverse developmental effects were observed when clozapine was administered orally to pregnant rats or rabbits during the period of organogenesis, or to pregnant rats during pregnancy and lactation, at doses up to approximately 0.4 and 0.9 times the maximum recommended human dose (MRHD) of 900 mg/day, for rats and rabbits respectively, based on mg/m 2 body surface area ( see Data ).

The background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defects, 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 embryo/fetal risk There is a risk to the mother from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide. Schizophrenia is 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.

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 have been exposed to antipsychotic drugs, including Clozapine ODT, during the third trimester of pregnancy. These symptoms have 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 Animal Data In embryofetal developmental studies, clozapine had no effects on maternal parameters, litter sizes, or fetal parameters when administered orally to pregnant rats and rabbits during the period of organogenesis at doses up to 0.4 and 0.9 times, respectively, the MRHD of 900 mg/day on a mg/m 2 body surface area basis. In peri/postnatal developmental studies, pregnant female rats were administered clozapine over the last third of pregnancy and until day 21 postpartum.

Observations were made on fetuses at birth and during the postnatal period; the offspring were allowed to reach sexual maturity and mated. Clozapine caused a decrease in maternal body weight but had no effects on litter size or body weights of either F1 or F2 generations at doses up to 0.4 times the MRHD of 900 mg/day on a mg/m 2 body surface area basis.

8.4Pediatric Use Safety and effectiveness of clozapine in pediatric patients have not been established.

🧓 Geriatric Use 150 words

8.5Geriatric Use There have not been sufficient numbers of geriatric patients in clinical studies utilizing clozapine to determine whether those over 65 years of age differ from younger subjects in their response to clozapine. Orthostatic hypotension and tachycardia can occur with Clozapine ODT treatment [see Boxed Warning and Warnings and Precautions (5.2) ]. Elderly patients, particularly those with compromised cardiovascular functioning, may be more susceptible to these effects.

Elderly patients may be particularly susceptible to the anticholinergic effects of Clozapine ODT, such as urinary retention and constipation [see Warnings and Precautions (5.15) ]. Carefully select Clozapine ODT doses in elderly patients, taking into consideration their greater frequency of decreased hepatic, renal, or cardiac function, as well as other concomitant disease and other drug therapy. Clinical experience suggests that the prevalence of tardive dyskinesia appears to be highest among the elderly; especially elderly women [see Warnings and Precautions (5.17) ].

🆘 Overdosage 128 words

10 OVERDOSAGE

10.1Overdosage Experience The most commonly reported signs and symptoms associated with Clozapine ODT overdose are: sedation, delirium, coma, tachycardia, hypotension, respiratory depression or failure; and hypersalivation. There are reports of aspiration pneumonia, cardiac arrhythmias, and seizure. Fatal overdoses have been reported with clozapine, generally at doses above 2500 mg.

There have also been reports of patients recovering from overdoses well in excess of 4 g.

10.2Management of Overdosage There are no specific antidotes for Clozapine ODT overdose. Establish and maintain an airway; ensure adequate oxygenation and ventilation.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The mechanism of action of clozapine is unknown. However, it has been proposed that the therapeutic efficacy of Clozapine ODT in schizophrenia is mediated through antagonism of the dopamine type 2 (D 2 ) and the serotonin type 2A (5-HT 2A ) receptors. Clozapine also acts as an antagonist at adrenergic, cholinergic, histaminergic and other dopaminergic and serotonergic receptors.

12.2Pharmacodynamics Clozapine demonstrated binding affinity to the following receptors: histamine H 1 (K i 1.1 nM), adrenergic α 1A (K i 1.6 nM), serotonin 5-HT 6 (K i 4 nM), serotonin 5-HT 2A (K i 5.4 nM), muscarinic M 1 (K i 6.2 nM), serotonin 5-HT 7 (K i 6.3 nM), serotonin 5-HT 2C (K i 9.4 nM), dopamine D 4 (K i 24 nM), adrenergic α 2A (K i 90 nM), serotonin 5-HT 3 (K i 95 nM), serotonin 5­-HT 1A (K i 120 nM), dopamine D 2 (K i 160 nM), dopamine D 1 (K i 270 nM), dopamine D 5 (K i 454 nM), and dopamine D 3 (K i 555 nM).

Clozapine causes little or no prolactin elevation. Clinical electroencephalogram (EEG) studies demonstrated that clozapine increases delta and theta activity and slows dominant alpha frequencies. Enhanced synchronization occurs.

Sharp wave activity and spike and wave complexes may also develop. Patients have reported an intensification of dream activity during clozapine therapy. REM sleep was found to be increased to 85% of the total sleep time.

In these patients, the onset of REM sleep occurred almost immediately after falling asleep.

12.3Pharmacokinetics Absorption In humans Clozapine ODT (25 mg and 100 mg) is equally bioavailable relative to a clozapine oral solution. Clozapine ODT is bioequivalent to Clozaril (clozapine) tablets. Following a dosage of 100 mg twice daily, the average steady-state peak plasma concentration was 413 ng/mL (range: 132 to 854 ng/mL), occurring at the average of 2.3 hours (range: 1 to 6 hours) after dosing.

The average minimum concentration at steady-state was 168 ng/mL (range: 45 to 574 ng/mL), after 100 mg b.i.d. dosing. A comparative bioequivalence/bioavailability study was conducted in 32 patients (with schizophrenia or schizoaffective disorder) comparing Clozapine ODT 200 mg to 2 × Clozapine ODT 100 mg (the approved reference product) under fasted conditions. The study also evaluated the effect of food and chewing on the pharmacokinetics of the 200 mg tablet.

Under fasted conditions, the mean AUC ss and C min,ss of clozapine for the 200 mg oral disintegrating tablets were equivalent to those of the 2 x 100 mg tablets. The mean C max,ss of clozapine for Clozapine ODT 200 mg was 85% that for 2 x 100 mg Clozapine ODT. This decrease in C max,ss for Clozapine ODT 200 mg is not clinically significant.

For Clozapine ODT 200 mg, food significantly increased the C min,ss of clozapine by 21%. However, this increase is not clinically significant. The mean AUC ss and C max,ss of clozapine under fed conditions were equivalent to those under fasted conditions.

Food delayed clozapine absorption by 1.5 hours, from a median T max of 2.5 hours under fasted conditions to 4 hours under fed conditions. The mean C max,ss of clozapine under chewed conditions for Clozapine ODT 200 mg was about 86% that for 2 x 100 mg Clozapine ODT under non-chewed conditions, while the AUC ss and C min,ss values were similar between the chewed and non-chewed conditions. In a food-effect study, a single dose of Clozapine ODT 12.5 mg was administered to healthy volunteers under fasting conditions and after a high-fat meal.

When Clozapine ODT were administered after a high-fat meal, the C max of both clozapine and its active metabolite, desmethylclozapine, were decreased by approximately 20%, compared to administration under fasting conditions, while the AUC values were unchanged. This decrease in C max is not clinically significant. Therefore, Clozapine ODT can be taken without regard to meals.
