An HPLC method using normal phase column eluted with an aqueous solvent and detected by fluorescence was applied to analyze sulpiride concentrations in plasma samples obtained from a comparative pharmacokinetic study. This comparative study was conducted to determine the bioequivalence of two tablet products (Dogmatyl and Sulpin) containing sulpiride on 12 normal healthy Chinese male volunteers in a single-dose, two-period, two-sequence, two-treatment crossover design. The pharmacokinetic parameters, AUC 0-last, AUC 0-inf, and C max, were calculated from plasma data and compared using the SAS General Linear Model computer program. A two one-sided t distribution test was also performed, as well as the 90% confidence interval method, to determine the mean difference of these three pharmacokinetic parameters. The results suggest that these two sulpiride tablet products are bioequivalent when orally administered in a 400 mg single dose of two tablets.
