Abstract

Objective: To investigate the formulation of gastroretentive microspheres of omeprazole along with piperine and estimate the pharmacokinetic parameters in comparison with omeprazole alone. Methods: In our present investigation, gastroretentive microspheres of omeprazole were prepared with the inclusion of piperine. Pharmacokinetic parameters like Cmax, Tmax and area under curve were estimated by administering the prepared microspheres to rabbits and the results were compared with omeprazole alone. Results: There was a significant increase in area under curve from 3.441依1.093 mg·h/mL to 14.422 依0.708 mg·h/mL along with an increase in Cmax. Conclusions: This clearly shows the increased absorption and decreased metabolism of omeprazole when administered along with piperine as gastroretentive microspheres.
