Drug information of Tioconazole


Tioconazole is an imidazole antifungal used to treat fungal and yeast infections.

Mechanism of effect

Tioconazole interacts with 14-α demethylase, a cytochrome P-450 enzyme that converts lanosterol to ergosterol, an essential component of the yeast membrane. In this way, tioconazole inhibits ergosterol synthesis, resulting in increased cellular permeability. Tioconazole may also inhibit endogenous respiration, interact with membrane phospholipids, inhibit the transformation of yeasts to mycelial forms and the uptake of purine, impair triglyceride and/or phospholipid biosynthesis, and inhibit the movement of calcium and potassium ions across the cell membrane by blocking the ion transport pathway known as the Gardos channel.


Tioconazole is a broad-spectrum imidazole antifungal agent that inhibits the growth of human pathogenic yeasts. Tioconazole exhibits fungicidal activity in vitro against Candida albicans, other species of the genus Candida, and against Torulopsis glabrata.
