The purpose of this study was to elucidate the pharmacokinetics of terazosin enantiomers in healthy Chinese male subjects. After a single oral dose of 2-mg terazosin, the plasma concentrations of terazosin enantiomers were measured over the course of 48 h in 12 healthy subjects. The plasma concentrations of (+)-(R)-terazosin at all time points were higher than those of (-)-(S)-terazosin. The area under the plasma concentration-time curve (AUC(0-∞) ) and maximum plasma concentration of (+)-(R)-terazosin were significantly greater than those of the (-)-(S)-terazosin (P < 0.01, respectively). The R/S ratio of AUC(0-∞) of terazosin was 1.68. For the first time, it was proven that the pharmacokinetics of terazosin was stereoselective in healthy Chinese male subjects.
