Pharmacology and clinical experience with risperidone.
Risperidone (Risperdal, Janssen Pharmaceutica) is a second generation antipsychotic (SGA) for the treatment of schizophrenia and other psychotic disorders. It is a potent antagonist of serotonin-2 (5-HT2) and dopamine-2 (D2) receptors in the brain. In comparison to conventional antipsychotics, risperidone demonstrates superior efficacy against the positive and negative symptoms of schizophrenia and a decreased occurrence of extrapyramidal side effects (EPS). Risperidone causes less weight gain than other marketed SGAs, but can increase prolactin levels and cause EPS in a dose-related manner. In a variety of pharmacoeconomic analyses, it has proven to be a cost-effective addition to the antipsychotic armamentarium. As the first SGA available for front line use, risperidone has established a new standard of care for the treatment of individuals with psychotic disorders.
