Ketoconazole (/ˌkiːtoʊˈkoʊnəˌzoʊl, -zɒl/) (INN, USAN, BAN, JAN) is a synthetic imidazole antifungal drug used primarily to treat fungal infections. Ketoconazole is sold commercially as a tablet for oral administration (although this use has been discontinued in a number of countries), and in a variety of formulations for topical administration, such as creams (used to treat tinea; cutaneous candidiasis, including candidal paronychia; and pityriasis versicolor) and shampoos (used primarily to treat dandruff—seborrhoeic dermatitis of the scalp).
