ABSTRACT:Microsphere of Enalapril malate were formulated by ionotropic gelation technique using like sodium alginate, HPMC, carbopol 940, Guar gum, Xanthum gum in different ratios. Prepared micropeletes were evaluated for flow behavior, drug entrapment efficiency, in-vitro dissolution and stability studies, including scanning electron microscopy and optical microscopy. Of the ten formulations prepared and evaluated formulations F3 containing HPMC 100 and carbopol found to show satisfactory results. The release of the drug from the micropeletes was found to be following Non-Fickian diffusion, Drug diffusion coefficient and correlation coefficient were also assessed by using various mathematical models. From the study it was concluded that prolonged release Enalapril malate micropeletes can be achieved with success using ionotropic gelation technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
