AbstractSarpogrelate is widely used to treat peripheral vascular disorders. However, it has been demonstrated to have a poor pharmacokinetic (PK) profile and marked within‐subject variability. Here, the bioequivalence of 2 formulations of sarpogrelate (100‐mg tablets) was assessed by using the reference‐scaled average bioequivalence (RSABE) method, and the PK parameters were quantified in healthy Chinese subjects under fasting (n = 38) and fed (n = 35) conditions. In this open and randomized 4‐way replicate study, a single dose of sarpogrelate was administered followed by a 3‐day washout period. The sarpogrelate concentration in blood samples was measured by liquid chromatography‐tandem mass spectrometry within 6 hours (fasting) or 10 hours (fed) of drug administration, and the PK parameters were determined by a noncompartmental model. The bioequivalence of the 2 formulations under both conditions was assessed using the ratios of ln(peak concentration [Cmax]) and ln(area under the concentration‐time curve [AUC]) within the limits based on the RSABE method. The 90% CIs for the ratios of lnCmax, lnAUC0‐t, and lnAUC0‐∞ were 0.8531–1.1100, 0.9616–1.0737, and 0.9550–1.0684, respectively, under fasting conditions and 0.8918–1.1076, 0.9818–1.0694, and 0.9818–1.0686, respectively, under fed conditions, which were within the RSABE acceptance limits. Food intake decreased the systemic exposure and the Cmax of sarpogrelate by 0.9‐fold and 0.5‐fold, respectively.
