Popis: © 2016, Springer Science+Business Media New York.In this work, we studied water solubility of ampicillin trihydrate and its solid dispersions (SD) with polyethylene glycol-1500, polyvinylpyrrolidone-10000, and β-cyclodextrin. It was found that SD formation increases the solubility by a factor of 1.34–1.73 and the rate of ampicillin dissolution by a factor of 3.43–7.40. The results of complex physicochemical studies suggest that the improved release of ampicillin from SD is due to its micronization and solubilization by the polymer.
