A mucoadhesive, cyclodextrin-based vaginal cream formulation of itraconazole.

The development of vaginal medications, especially antifungal medications, requires that the drug is solubilized as well as retained at or near the mucosa for sufficient periods of time to ensure adequate bioavailability. Itraconazole is a broad-spectrum antifungal agent, which has been used for some time orally and intravenously but for which a vaginal formulation has not yet been developed. We present here a novel itraconazole formulation intended for vaginal use based on hydroxypropyl-beta-cyclodextrin (HPbetaCD), a functional excipient that increases drug solubility and generates a mucoadhesive system in the presence of other ingredients.
