Brief Summary

Risperidone is a selective monoamine receptor antagonist. It plays an antipsychotic effect by antagonizing 5-HT2 / D2 receptor. As a second-generation antipsychotic drug, risperidone is metabolized to 9-hydroxy Risperidone in the body very quickly. There are individual differences in the pharmacokinetics and pharmacodynamics of risperidone. For example, CYP2D6 genotype can greatly affect the metabolism of risperidone, and provide evidence for adjusting the type and dose of medication to treat Schizophrenia. In this study, we will verify the correlation between the polymorphisms of genes related with risperidone drug metabolites, drug transporters, drug targets and drug metabolism, pharmacodynamics, adverse reactions in Chinese population, providing basis for clinical rational use of risperidone.

Schizophrenic patients who are going to be treated with risperidone.

You may qualify if:

  • patients that meet with DSM-IV-TR schizophrenia diagnostic criteria, based on concise International Neuropsychiatric Interview (MINI);
  • patients who have never received risperidone treatment or who need re-administration of risperidone after previous treatment with risperidone;

You may not qualify if:

  • patients who use CYP2D6 or CYP3A4 inducers or inhibitors as treatment drugs;
  • patients with hepatic insufficiency;
  • patients with renal insufficiency;
  • patients who use other drugs that interact with risperidone;
  • certain patients that the researchers consider to be unsuitable for the clinical trail.

Biospecimen

Retention: SAMPLES WITH DNA

Whole blood samples will be drawn and collected, serum sample will also be obtained by centrifugation of whole blood at 4 ℃. The collected samples will be further detected and the concentration data will be used for PG-PK, PG-PD and PG-ADR analyses.
