Ketoconazole, sold under the brand name Nizoral among others, is an antiandrogen, antifungal, and antiglucocorticoid medication used to treat a number of fungal infections.[11] Applied to the skin it is used for fungal skin infections such as tinea, cutaneous candidiasis, pityriasis versicolor, dandruff, and seborrheic dermatitis.[12] Taken by mouth it is a less preferred option and only recommended for severe infections when other agents cannot be used.[11] Other uses include treatment of excessive male-patterned hair growth in women and Cushing's syndrome.[11]
Common side effects when applied to the skin include redness.[12] Common side effects when taken by mouth include nausea, headache, and liver problems.[11] Liver problems may result in death or the need for a liver transplantation.[11][13] Other severe side effects when taken by mouth include QT prolongation, adrenocortical insufficiency, and anaphylaxis.[11][13] It is an imidazole and works by hindering the production of ergosterol required for the fungal cell membrane, thereby slowing growth.[11]
Ketoconazole was patented in 1977 by Belgian pharmaceutical company Janssen, and came into medical use in 1981.[14] It is available as a generic medication and formulations that are applied to the skin are over the counter in the United Kingdom.[12] In 2021, it was the 161st most commonly prescribed medication in the United States, with more than 3 million prescriptions.[15][16] The formulation that is taken by mouth was withdrawn in the European Union and in Australia in 2013,[17][18] and in China in 2015.[19] In addition, its use was restricted in the United States and Canada in 2013.[18]
