Thorazine

Thorazine is a prescription medication used to treat certain psychiatric disorders such as schizophrenia. Thorazine can also be used to treat nausea and vomiting. Thorazine belongs to a group of medications called antipsychotics. These work by changing the activity of certain natural substances in the brain.

Elderly patients with dementia-related psychosis treated with atypical 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, similar to atypical antipsychotic drugs, treatment with conventional 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. Chlorpromazine hydrochloride is not approved for the treatment of patients with dementia-related psychosis.
