title: Stability of Two Antifungal Agents, Fluconazole and Miconazole, Compounded in HUMCO RECURA Topical Cream to Determine Beyond-Use Date.
abstract: A novel compounding vehicle (RECURA) has previously been proven to penetrate the nail bed when compounded with the antifungal agent miconazole or fluconazole, providing for an effective treatment for onychomycosis. In this study, miconazole and fluconazole were compounded separately in RECURA compounding cream, and they were tested at different time points (0, 7, 14, 28, 45, 60, 90, and 180 days) to determine the beyond-use date of those formulations. The beyond-use date testing of both formulations (10% miconazole in RECURA and 10% fluconazole in RECURA) proved them to be physically, chemically, and microbiologically stable under International Conference of Harmonisation controlled room temperature (25°C ± 2°C/60% RH ±5%) for at least 180 days from the date of compounding. Stability-indicating analytical method validation was completed for the simultaneous determination of miconazole and fluconazole in RECURA base using high-performance liquid chromatography coupled with photodiode array detector prior to the study.
