Objective:
To review the pharmacology, pharmacokinetics, clinical efficacy, and safety profile of long-acting (LA) risperidone for the treatment of schizophrenia.
Data Sources:
Information was selected from PubMed (1965-July 2004). Applicable scientific posters were also used.
Study Selection And Data Extraction:
All published information on risperidone LA was considered. Material providing a comprehensive description was considered.
Data Synthesis:
Risperidone LA is the first long-acting, injectable atypical antipsychotic. It is dosed at 25-50 mg every 2 weeks. Adverse effects are similar to those seen with oral risperidone. A short-term study showed that risperidone LA is better than placebo in reducing the signs and symptoms of schizophrenia, and a long-term trial showed that stable schizophrenic patients can be switched from either oral or other injectable antipsychotic medications to risperidone LA.
Conclusions:
Risperidone LA is efficacious and safe in the treatment of schizophrenia.
