Antifungal refers to a type of medication or treatment designed to combat fungal infections. These infections can affect various parts of the body, including the skin, nails, and internal organs. Common antifungal agents include fluconazole, itraconazole, and clotrimazole, which work by inhibiting the growth of fungi or killing them outright. Fungal infections can be caused by different types of fungi, such as Candida and Aspergillus. Antifungal treatments are essential for individuals with weakened immune systems, as they are more susceptible to these infections. Proper diagnosis and treatment are crucial for effective management of fungal diseases.
