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 |
