Itraconazole is an antifungal medication used to treat a variety of fungal infections [1]. It is available in different formulations, including 100mg tablets [1].
What conditions does itraconazole 100mg treat?
Itraconazole 100mg tablets are prescribed for fungal infections affecting the skin, nails, and mucous membranes. These can include onychomycosis (nail fungus), pityriasis versicolor, and certain types of yeast infections [1]. It is also used for more serious systemic fungal infections, such as aspergillosis, candidiasis, and cryptococcosis, often in individuals with weakened immune systems [1].
How does itraconazole work?
Itraconazole belongs to a class of drugs called azole antifungals [1]. It works by inhibiting the synthesis of ergosterol, a crucial component of fungal cell membranes. By disrupting ergosterol production, itraconazole compromises the integrity of the fungal cell membrane, leading to fungal cell death [1].
