Background: Schizophrenia is a severe mental disorder characterized by positive, negative, and cognitive
symptoms that affect the quality of life. Risperidone is widely known as second-generation antipsychotic
that is effective to treat schizophrenia. Unlike the first-generation antipsychotic, risperidone has a lower
impact on the extrapyramidal adverse effect. However, individually, the risperidone treatment response may
be different caused by the genetic polymorphisms. This review aims to examine the association of genetic
polymorphisms with risperidone treatment response in schizophrenia.
Method: The review was conducted using the Pubmed database and 49 articles included in this review
among 80 articles obtained in an initial search. The result showed genetic polymorphisms which affects
risperidone therapy include DRD2, genetic polymorphisms on serotonin, cytochrome P450, BDNF, COMT,
and ABCB1. Those polymorphisms might increase or decrease pharmacokinetics and pharmacodynamic
profile of risperidone. In addition, genetic polymorphisms also contributed to the risk of metabolic syndrome
and hyperprolactinemia induced by risperidone treatment.
Conclusion: Based on those findings, several genetic polymorphisms had an association with therapeutic
outcomes and side effect after risperidone treatment. Genetic polymorphisms screening may be useful for
drug choices or dosage adjustment that safer and effective for patients.
