Simultaneously enhancing the solubility and permeability of acyclovir by crystal engineering approach

Abstract

Three acyclovir complexes including one salt with maleic acid, and two cocrystals with fumaric acid and glutaric acid, were prepared. The results of powder dissolution and in vitro skin permeation experiments revealed that both solubility and permeability of acyclovir were enhanced after the formation of cocrystals.
