Abstract
Objective To evaluate the bioequivalence of domestic and imported terazosin hydrochloride tablets after single oral dose. Methods It was a single center, randomized, open, cross-over trail design, 21 subjects were fasting oral administered of 2 mg domestic and imported terazosin hydrochloride tablets in different periods, venous blood 4 ml were collected in different time points before and 60 h after administration, plasma concentration of terazosin was determined by LC-MS/MS. Results The main pharmacokinetic parameters of domestic and imported terazosin hydrochloride tablets were as follows:t1/2 : (13.2± 2.39) h vs (12.5±1.93) h, tmax: (1.01±0.83) h vs (1.08±0.69) h, Cmax: (40.1±10.6) ng/ml vs (37.3±9.57) ng/ml; AUC0- ∞: (428±82.1) ng·h/ml vs (426±85.2) ng·h/ml. The relative bioavailability of domestic terazosin hydrochloride tablets was (101.2±14.7)%. 90% CI of domestic and imported terazosin hydrochloride tablets AUC0-t and Cmax geometric mean ratio fell between 80%-125%. Conclusion The domestic tablets are bioequivalent to the imported tablets.
