Biopharmaceutical Investigations of Microcapsulated Drug Formulation of Vinpocetine

In the experimental investigations using dispersion technique microcapsulated drug formulation of vinpocetine was obtained in a system «liquid-liquid». The process of release of the drug substance from microcapsules was studied in vitro in a dependence on the size of drug formulation, composition of the shell and dispersion medium where microcapsules were obtained. Optimal composition was selected for the elaborated drug formulation. Fused beeswax and cocoa butter in the ratio of 3:2 was found to be the most rational composition for the microcapsules with vinpocetine where the purified water and 2% solution of Na-CM cellulose was applied as dispersion medium.
