Pharmacology Of Oxiconazole

Indication For treatment of dermal fungal infection.
Pharmacodynamics Oxiconazole is a broad-spectrum imidazole derivative whose antifungal activity is derived primarily from the inhibition of ergosterol biosynthesis, which is critical for cellular membrane integrity. It has fungicidal or fungistatic activity in vitro against a number of pathogenic fungi including the following dermatophytes, and yeasts: T. rubrum, T. mentagrophytes, T. tonsurans, T. violaceum, E. floccosum, M. canis, M. audouini, M. gypseum, C. albicans, and M. furfur.
Mechanism of action Oxiconazole inhibits ergosterol biosynthesis, which is required for cytoplasmic membrane integrity of fungi. It acts to destabilize the fungal cyctochrome P450 51 enzyme (also known as Lanosterol 14-alpha demethylase). This is vital in the cell membrance structure of the fungus. Its inhibition leads to cell lysis. Oxiconazole has also been shown in inhibit DNA synthesis and suppress intracellular concentrations of ATP. Like other imidazole antifungals, Oxiconazole can increase membrane permeability to zinc, augmenting its cytotoxicity.
Absorption Systemic absorption of oxiconazole is low.
