Abstract:
AIM: To study pharmacokinetics and relative bioavailability of pantoprazole sodium enteric-coated test and reference tablets in healthy volunteers. METHODS: A single oral dose of 40 mg pantoprazole sodium enteric-coated test and reference tablets were given to 20 male healthy volunteers in a randomized two-way crossover design. Plasma concentrations of pantoprazole were determined by HPLC method. Pharmacokinetic parameters and relative bioavailability were calculated with DAS program to evaluate the bioequivalence of the two preparations. RESULTS: Plasma concentration-time profiles were adequately described by a two-compartment open model. The main pharmacokinetic parameters of pantoprazole sodium test and reference tablets were as follow: The values of Tmax were (3.18±0.54) and (3.30±0.47) h, Cmax were (2.98±0.83) and (2.91±0.87) mg·L-1, T1/2β were (1.86±0.41) and (1.72±0.48) h, AUC0-t were (9.51±3.71) and (9.77±4.55) mg·h·L-1, respectively. The relative bioavailability of test tablets was (102.3±19.6)%. CONCLUSION: The two preparations of pantoprazole sodium are bioequivalent.
