Itraconazole, sometimes abbreviated ITZ, is an antifungal medication used to treat a number of fungal infections.[7] This includes aspergillosis, blastomycosis, coccidioidomycosis, histoplasmosis, and paracoccidioidomycosis.[7] It may be given by mouth or intravenously.[7]

Common side effects include nausea, diarrhea, abdominal pain, rash, and headache.[7] Severe side effects may include liver problems, heart failure, Stevens–Johnson syndrome and allergic reactions including anaphylaxis.[7] It is unclear if use during pregnancy or breastfeeding is safe.[1] It is in the triazole family of medications.[7] It stops fungal growth by affecting the cell membrane or affecting their metabolism.[7]

Itraconazole was patented in 1978 and approved for medical use in the United States in 1992.[7][8] It is on the World Health Organization's List of Essential Medicines.[9]

Recent research works suggest itraconazole (ITZ) could also be used in the treatment of cancer by inhibiting the hedgehog pathway[10] in a similar way to sonidegib.
