Tardive dyskinesia TD has occurred in patients treated with antipsychotic drugs, including Clozaril. The syndrome consists of potentially irreversible, involuntary, dyskinetic movements. The risk of TD and the likelihood that it will become irreversible are believed to increase with greater durations of treatment and higher total cumulative doses. However, the syndrome can develop after relatively brief treatment periods at low doses. Prescribe Clozaril in a manner that is most likely to minimize the risk of developing TD. Use the lowest effective dose and the shortest duration necessary to control symptoms. Periodically assess the need for continued treatment. Consider discontinuing treatment if TD occurs. However, some patients may require treatment with Clozaril despite the presence of the syndrome. etok.info hydroxyzine

Clozaril is taken orally in tablet form, and an orally-disintegrating tablet that can be taken without water is available. While you are taking clozapine, your blood may need to be tested every week for the first 6 months of treatment. It has been associated with in some patients, a potentially fatal decrease in a certain type of white blood cells. Clozaril may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects. To prevent them, sit up or stand slowly, especially in the morning.

Keep this and all drugs out of the reach of children. It is unclear if concurrent use of other drugs known to cause neutropenia increases the risk or severity of clozapine-induced neutropenia. There is no strong scientific rationale to avoid clozapine treatment in patients concurrently treated with these drugs. QT Interval Prolongation: Advise patients to consult their clinician immediately if they feel faint, lose consciousness or have signs or symptoms suggestive of arrhythmia. Instruct patients to not take Clozaril with other drugs that cause QT interval prolongation. Orthostatic hypotension, bradycardia, syncope, and cardiac arrest reported. 1 Such reactions, which can be fatal, are more likely to occur during initial titration period, particularly with rapid dosage escalation. Possible increased risk of seizures; use concomitantly with caution. In patients with poor metabolizer phenotypes of CYP2D6, increased plasma clozapine concentrations are possible at usual dosages. However, other published reports describe modest elevations less than 2-fold of clozapine and metabolite concentrations when clozapine was taken with paroxetine, fluoxetine, and sertraline. Coward DM, Imperato A, Urwyler S et al. Biochemical and behavioural properties of clozapine. Psychopharmacology. The efficacy of clozapine in treatment-resistant schizophrenia was established in a multicenter, randomized, double-blind, active-controlled chlorpromazine study in patients with a DSM-III diagnosis of schizophrenia who had inadequate responses to at least three different antipsychotics from at least two different chemical classes during the preceding 5 years. The antipsychotic trials must have been judged adequate; the antipsychotic dosages must have been equivalent to or greater than 1000 mg per day of chlorpromazine for a period of at least 6 weeks, each without significant reduction of symptoms. There must have been no period of good functioning within the preceding 5 years. Patients must have had a baseline score of at least 45 on the investigator-rated Brief Psychiatric Rating Scale BPRS. On the 18-item BPRS, 1 indicates the absence of symptoms, and 7 indicates severe symptoms; the maximum potential total BPRS score is 126. At baseline, the mean BPRS score was 61. In addition, patients must have had a score of at least 4 on at least two of the following four individual BPRS items: conceptual disorganization, suspiciousness, hallucinatory behavior, and unusual thought content. Patients must have had a Clinical Global Impressions - Severity Scale score of at least 4 moderately ill. Baldessarini RJ, Frankenburg FR. Clozapine: a novel antipsychotic agent. N Engl J Med. 1991; 324: 746-54. Monitor ANC if fever occurs during the 2 weeks after discontinuance. Risks associated with the use of clozapine include severe neutropenia, orthostatic hypotension, seizures, myocarditis, cardiomyopathy, and mitral valve incompetence. Severe neutropenia can lead to serious infection and death. Monitor absolute neutrophil count ANC prior to and during treatment. Monitor for symptoms of severe neutropenia and infection. Clozapine is available only through a restricted program under a Risk Evaluation Mitigation Strategy REMS called the Clozapine REMS Program. Orthostatic hypotension, bradycardia, syncope, cardiac arrest, and seizures have occurred. The risk is dose-related. Study. This was an adequate and well-controlled, 2-year study evaluating the efficacy of clozapine relative to olanzapine in reducing the risk of suicidal behavior in patients with schizophrenia or schizoaffective disorder.

The cumulative incidence is estimated at 1% to 2% after one year of use. The onset is generally between 4 to 16 weeks following initiation of therapy, and it is usually reversible if detected early and the drug discontinued promptly.

Reference Listed Drug RLD is an approved drug product to which new generic versions are compared to show that they are bioequivalent. A drug company seeking approval to market a generic equivalent must refer to the Reference Listed Drug in its Abbreviated New Drug Application ANDA. By designating a single reference listed drug as the standard to which all generic versions must be shown to be bioequivalent, FDA hopes to avoid possible significant variations among generic drugs and their brand name counterpart. Going on 7 years we have had no success with any of the medications she has tried since day one.

Clozapine Orally Disintegrating Tablets. Clozaril and is associated with an increase in the risk of serious and potentially fatal infections. Risk of neutropenia appears greatest during the first 18 weeks on treatment and then declines. The mechanism by which Clozaril causes neutropenia is unknown and is not dose-dependent. Approximately 88% of patients from the clozapine and chlorpromazine groups completed the 6-week trial. At the end of 6 weeks, 30% of the clozapine group responded to treatment, and 4% of the chlorpromazine group responded to treatment. Henderson VW, Wooten GF.
