FORMULATION AND EVALUATION OF FLOATING IN SITU GEL OF RANITIDINE USING NATURAL POLYMERS
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2014, Vol 6, Issue 10
Abstract
Objective: To formulate and evaluate floating in situ gel of Ranitidine using natural polymers like sodium alginate and pectin and calcium carbonate as cross-linking agent.Methods: The in situ gel was prepared by mixing sodium alginate (SA), calcium carbonate, sodium citrate and ranitidine. The formulated in situ gel was evaluated for physicochemical parameters, In vitro buoyancy study and In vitro release study.Results: The In vitro drug release profile demonstrated the positive effect of concentration of both sodium alginate (SA) and Calcium Carbonate on comparing various formulations. It was also found that the ratio of SA and CaCO3 also affects the release pattern. The drug release pattern from the formulations was found to follow Fickian diffusion of the drug.Conclusion: With the suitable concentration of SA and CaCO3, the sustained release of the drug can be achieved by in situ gel along with good floating properties. Thus, this approach provides a potential development of sustained release floating in situ system of the liquid preparations.Â
