Miconazole

Brand Names: Daktarin

Drug Class: Imidazole antifungal

Overview

Miconazole is an antifungal medication used to treat various fungal infections. It works by inhibiting ergosterol synthesis in fungal cell membranes, leading to cell death. This specific formulation is indicated for veterinary use in dogs and cats.

Mechanism of Action

Miconazole inhibits the synthesis of ergosterol, an essential component of fungal cell membranes, by blocking the enzyme lanosterol 14α-demethylase. This disruption compromises membrane integrity and function, leading to fungal cell death.
