Overview
Antifungal medications are crucial in veterinary medicine to treat various fungal infections in pets, including dogs and cats. These infections can range from superficial skin conditions to more severe systemic infections. It is essential to follow veterinary guidance for proper use and dosage.
How It Works
Antifungal medications work by disrupting the cell membrane of fungi, thereby inhibiting their growth and reproduction. Azole antifungals, such as Ketoconazole and Itraconazole, interfere with the synthesis of ergosterol, a key component of fungal cell membranes.
