4

This broad-spectrum triazole antifungal is used to treat various fungal infections including aspergillosis, histoplasmosis, blastomycosis, onychomycosis, and candidiasis. It works by inhibiting ergosterol synthesis, an essential component of the fungal cell membrane. It has many drug interactions due to its inhibition of liver cytochrome P450 enzymes.
