Ziprasidone (Intramuscular route)
Warnings:Intramuscular route(Powder for Solution)
Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death compared with placebo. Although the causes of death in clinical trials were varied, most of the deaths appeared to be either cardiovascular (eg, heart failure, sudden death) or infectious (eg, pneumonia) in nature. Observational studies suggest that antipsychotic drugs may increase mortality. It is unclear from these studies to what extent the mortality findings may be attributed to the antipsychotic drug as opposed to patient characteristics. Ziprasidone mesylate is not approved for the treatment of patients with dementia-related psychosis .
