Jazz Pharmaceuticals, Inc. FazaClo clozapine orally disintegrating tablets prescribing information. Palo Alto, CA; 2015 Sep. 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 to12 hours compared to a mean elimination half-life of 12 hours range: 4-66 hours after achieving steady state with 100 mg twice daily dosing. CloZAPine may occasionally cause serious cardiovascular side effects such as low blood pressure and cardiac or respiratory arrest, and combining it with other medications that can can also have these effects such as ARIPiprazole may increase the risk. Cardiovascular side effects are most likely to occur at the beginning of treatment, following a dose increase, or when treatment is restarted after an interruption. Other side effects that may also be increased include dizziness, drowsiness, blurred vision, confusion, dry mouth, abdominal cramping, constipation, difficulty urinating, heat intolerance, low white blood cell count, palpitation, and irregular heart rhythm. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. You should avoid or limit the use of alcohol while being treated with these medications. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. If you miss your cloZAPine doses for two or more days, contact your doctor before you resume treatment, as you may need to restart at a lower dose. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor. 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. disulfiram plus generic disulfiram

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of clozapine in the elderly. However, elderly patients are more likely to have constipation, trouble passing urine, uncontrolled movements, or age-related liver, kidney, or heart problems, which may require caution in patients receiving clozapine. Treatment with Clozaril can result in gastrointestinal adverse reactions, including constipation, intestinal obstruction, fecal impaction, and paralytic ileus. Such reactions can be fatal. Constipation should be initially treated by ensuring adequate hydration and use of ancillary therapy such as bulk laxatives. Consultation with a gastroenterologist is advisable in more serious cases.

For the 956 patients who received clozapine or olanzapine in this study, there was extensive use of concomitant psychotropics: 84% with antipsychotics, 65% with anxiolytics, 53% with antidepressants, and 28% with mood stabilizers. There was significantly greater use of concomitant psychotropic medications among the patients in the olanzapine group. Rapidly and extensively distributed into human body tissues; 2 16 43 metabolites also appear to be extensively distributed. Based on Clozaril National Registry US patients data collected up to April 1995, a hematologic risk analysis found the incidence of agranulocytosis rises steeply during the first 2 months, peaks at approximately the third month, and decreases at 6 months of therapy; after 6 months the incidence decreases further, however, it never reaches zero.
Musculoskeletal System and Connective Tissue Disorders: Myasthenic syndrome, rhabdomyolysis, and systemic lupus erythematosus. 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. 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. where can i crestor skin cream
