Abstract

The purposes of this study were to evaluate the relationship between the genetic polymorphisms in CYP2D6*10 allele, MDR1 (exon 21 and 26) gene and risperidone pharmacokinetics in healthy male Korean subjects. A single dose of 2 mg risperidone tablet was given orally to 23 healthy male Korean volunteers. Blood samples were taken during the 12 hours after the dose. Serum concentrations of risperidone and 9-hydroxyrisperidone were measured using HPLC with UV detector. 23 subjects were genotyped for CYP2D6*10 allele, MDR1 G2677 T and C3435T by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).
