Antifungal therapy involves the use of medications to treat infections caused by fungi. These infections can affect various parts of the body, including the skin, nails, and internal organs. Common antifungal medications include fluconazole, itraconazole, and amphotericin B, which work by targeting the cell membranes or cell walls of fungi, preventing their growth and reproduction. The choice of antifungal treatment depends on the type of fungal infection and its severity. Some infections may require topical treatments, while others might need systemic therapy, which involves taking medication orally or through an injection. Proper diagnosis and treatment are essential for effective management of fungal infections.
