Renal Dose Adjustments
Oral: No adjustment recommended
IM: Use cautiously as the cyclodextrin excipient is cleared by renal filtration; IM formulation has not been systematically studied in patients with renal impairment.
Liver Dose Adjustments
Oral: No adjustment recommended.
IM: Use with caution; IM formulation has not been systematically studied in patients with hepatic impairment.
Therapy with oral ziprasidone should replace IM administration as soon as possible.
No dosage adjustment is required in elderly patients, however, consider a lower oral starting dose and slower dose titration with careful monitoring during initial dosing period. .
In maintenance therapy, patients should be administered the lowest effective dose; to ensure the use of the lowest effective dose for the treatment of schizophrenia, patients should be observed for signs of improvement over a period of several weeks prior to upward dosage adjustment.
US BOXED WARNING: 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. Analyses 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. This drug is not approved for the treatment of patients with dementia-related psychosis.
Safety and efficacy in patients younger than 18 years have not been established.
