ABSTRACT
AIM: To assess the bioequivalence of oral dexamethasone acetate tablets between the test and reference formulations in healthy adult Chinese subjects on an empty stomach and after meals. METHODS: A randomized, open, single-dose, two-cycle double crossover bioequivalence study was followed. Twenty-four healthy subjects were included in the fasting group, and 32 healthy subjects were included in the postprandial group, taking 2 tablets (0.75 mg/tablet) of the test formulation (T) or 3 tablets (0.50 mg/tablet) of the reference formulation (R) per cycle for two cycles. The concentrations of dexamethasone acetate in human plasma were determined using liquid chromatography-mass spectrometry, and the pharmacokinetic parameters were calculated according to the non-atrial model using WinNonlin 8.0 software.The bioequivalence of both the test formulation and the reference formulation was evaluated. RESULTS: The pharmacokinetic parameters after oral administration of dexamethasone acetate tablets in a fasted state in subjects with the reference formulation are as follows: Tmax 1.13 (0.50, 4.00) and 1.00 (0.50, 5.00) h, AUC0-t (72.25±21.55) and (69.23±17.76) ng · mL
