Atypical antipsychotic drugs, including clozapine have been associated with metabolic changes that can increase cardiovascular and cerebrovascular risk. These metabolic changes include hyperglycemia, dyslipidemia, and body weight gain. While atypical antipsychotic drugs may produce some metabolic changes, each drug in the class has its own specific risk profile. Metabolic Changes hyperglycemia and diabetes mellitus, dyslipidemia, weight gain: Educate patients and caregivers about the risk of metabolic changes and the need for specific monitoring. The risks include hyperglycemia and diabetes mellitus, dyslipidemia, weight gain, and cardiovascular reactions. vistaril cheap purchase online mastercard
Clozapine is almost completely metabolized prior to excretion, and only trace amounts of unchanged drug are detected in the urine and feces. Clozapine is a substrate for many cytochrome P450 isozymes, in particular CYP1A2, CYP2D6, and CYP3A4. Approximately 50% of the administered dose is excreted in the urine and 30% in the feces. The demethylated, hydroxylated, and N-oxide derivatives are components in both urine and feces. Pharmacological testing has shown the desmethyl metabolite norclozapine to have only limited activity, while the hydroxylated and N-oxide derivatives were inactive. The mean elimination half-life of clozapine after a single 75 mg dose was 8 hours range: 4 to 12 hours compared to a mean elimination half-life of 12 hours range: 4 to 66 hours after achieving steady-state with 100 mg twice daily dosing. Weekly blood tests are required for the first 6 months. Respiratory System: Aspiration, pleural effusion, pneumonia, lower respiratory tract infection. Unit dose blister packages of 40 5 cards of 8 tablets each. Gastrointestinal System: Acute pancreatitis, dysphagia, salivary gland swelling. CNS pathology, central anticholinergic toxicity, extrapyramidal symptoms, and drug fever. Postmarketing, very rare events of ventricular tachycardia, cardiac arrest, and QT prolongation which may be associated with Torsades de pointes have been observed, although there is no conclusive causal relationship to use of this drug. An ANC is required every 2 weeks for the next 6 months if an acceptable ANC is maintained during the first 6 months of continuous therapy.

Clozaril 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.

Treatment outcome with clozapine in tardive dyskinesia, neuroleptic sensitivity, and treatment-resistant psychosis. J Clin Psychiatry. Because of the risk of severe neutropenia, regular ANC monitoring is required during clozapine therapy. 1 408 Obtain baseline CBC count, including ANC, prior to initiation of clozapine, then monitor ANC at recommended intervals during therapy. Concomitant treatment with drugs that induce CYP1A2 or CYP3A4 can decrease the plasma concentration of clozapine, resulting in decreased effectiveness of Clozapine Orally Disintegrating Tablets. Tobacco smoke is a moderate inducer of CYP1A2. No specific pharmacokinetic studies were conducted to investigate the effects of renal or hepatic impairment on the pharmacokinetics of clozapine. Higher clozapine plasma concentrations are likely in patients with significant renal or hepatic impairment when given usual doses. Use Clozaril with caution in the ELDERLY; they may be more sensitive to its effects, especially blood problems, dizziness especially when standing fast heartbeat, urinary problems, and constipation. silagra
