ABSTRACT
OBJECTIVE:
To study the pharmacokinetics and bioequivalence of both domestic ranitidine hydrochloride capsules and imported ranitidine hydrochloride tablets.METHODS:
20healthy volunteers were randomized into groups,whose plasma concentrations of ranitidine were determined at different time after single oral dose of300mg ranitidine hydrochloride capsule or ranitidine hydrochloride tablets300mg by own control by a RP-HPLC method,the pharmacokinetic parameters were computed and which were experienced variance analysis and two-way t-tests and one-way t-tests.RESULTS:
The respective pharmacokinetic parameters of ranitidine hydrochloride tablets and ranitidine hydrochloride capsuless were as fol?lows,the C max were(1247.1?547.5)?g/L and(1294.8?613.2)?g/L;t max were(2.98?0.73)h and(2.73?0.80)h;t 1/2 were(3.17?0.36)h and(3.33?0.42)h;AUC 0~t were(5805.9?1403.5)(?g?h)/L and(5941.2?1526.3)(?g?h)/L;AUC 0~∞ were(6163.8?1456.4)(?g?h)/L and(6351.8?1652.7)(?g?h)/L;The relative bioavailability of the ranitidine hydrochloride capsules to ranitidine hydrochloride tablets was(104.3?24.3)%.CONCLUSION:
Ranitidine hydrochloride capsules and the ranitidine hydrochloride tablets were bioequivalent.
