Bioequivalence study of cetirizine hydrochloride tablets under fasting and fed conditions / 中国临床药理学与治疗学

AIM: To evaluate the pharmacokinetics and bioequivalence of cetirizine hydrochloride tablets under fasting and fed conditions in Chinese healthy subjects. METHODS: This was a randomized, open-label, double-sequence, two-period, crossover designed study, and healthy subjects enrolled and administrated a single dose of 10 mg test and reference cetirizine hydrochloride tablets in each period under fasting or fed condition. The plasma concentrations of cetirizine were determined by a validated LC-MS/MS method. The pharmacokinetic parameters were calculated with WinNonlin 6.3 and the bioequivalence was evaluated through SAS 9.4 software. RESULTS: In the fasting condition, the major pharmacokinetic parameters of cetirizine of test and reference formulations were as follows, C
