Introduction to Itraconazole

Itraconazole is a medication used to treat a variety of fungal infections. It is particularly effective against infections caused by fungi such as Aspergillosis, Histoplasmosis, and Blastomycosis. It is also used for treating Onychomycosis, which is a fungal infection of the nails, as well as Candidiasis and Dermatophyte infections like athlete's foot and ringworm.

The active ingredient in Itraconazole is Itraconazole itself. It works by inhibiting the synthesis of a substance called ergosterol, which is a vital component of fungal cell membranes.
