Itraconazole Capsules are a prescription antifungal medication widely used to treat a variety of fungal infections, including those affecting the lungs, skin, nails, and other internal organs. They work by inhibiting the growth of fungi, effectively stopping the spread of infection. These capsules are particularly effective against infections caused by Candida, Aspergillus, and other common fungal pathogens. Itraconazole is available in different strengths and is typically taken orally with food to improve absorption.
