Abstract
The pharmacokinetics of a single oral dose of 6 mg perphenazine was studied in a group of six slow and six rapid hydroxylators of debrisoquin. Peak serum concentrations of perphenazine were significantly higher in slow hydroxylators than they were in rapid hydroxylators (2.4 +/- 0.6 versus 0.7 +/- 0.3 nmol/L, p less than 0.001). The AUC(0-12) was also higher in slow hydroxylators than it was in rapid hydroxylators (18.5 +/- 6.2 versus 4.5 +/- 2.5 nmol.L-1.hr, p less than 0.001). The data suggest that the disposition of the antipsychotic drug perphenazine covaries with polymorphic debrisoquin hydroxylation.Keywords
