Antifungal drugs are a class of medications used to treat fungal infections in humans. Fungal infections can range from mild, such as athlete's foot or yeast infections, to life-threatening systemic infections. Antifungal drugs work by either killing the fungus or inhibiting its growth. There are several classes of antifungal drugs, including azoles, echinocandins, and polyenes, each with their own mechanism of action and spectrum of activity. These medications can be administered orally, topically, or intravenously, depending on the severity and location of the infection. Some common antifungal drugs include fluconazole, amphotericin B, and clotrimazole. It is important to use these medications as directed by a healthcare professional to ensure effective treatment and minimize the risk of developing resistance.
