5 Pharmacology and Biochemistry
5.1 Pharmacology

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. Tioconazole prevents the growth and function of some fungal organisms by interfering with the production of substances needed to preserve the cell membrane. This drug is effective only for infections caused by fungal organisms. It will not work for bacterial or viral infections.


5.2 MeSH Pharmacological Classification

14-alpha Demethylase Inhibitors

Compounds that specifically inhibit STEROL 14-DEMETHYLASE. A variety of azole-derived ANTIFUNGAL AGENTS act through this mechanism. (See all compounds classified as 14-alpha Demethylase Inhibitors.)


Antifungal Agents

Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues. (See all compounds classified as Antifungal Agents.)

5.5 Absorption, Distribution and Excretion

Absorption

Systemic absorption following a single intravaginal application of tioconazole in nonpregnant patients is negligible.


5.6 Metabolism/Metabolites

Orally administered tioconazole is extensively metabolized. The major metabolites are glucuronide conjugates.


5.7 Mechanism of Action

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.
