Antifungal drugs are medications used to treat infections caused by fungi. These infections can affect various parts of the body, including the skin, nails, and internal organs. Common types of antifungal drugs include azoles, echinocandins, and polyene antibiotics, each working in different ways to inhibit fungal growth or kill the fungi. These drugs are essential for managing conditions like athlete's foot, ringworm, and more serious infections such as candidiasis or aspergillosis. While antifungal treatments can be effective, they may also have side effects, so it's important for patients to follow their healthcare provider's guidance when using them.
