Miconazole is an imidazole antifungal agent, developed by Janssen Pharmaceutica, commonly applied topically to the skin or to mucous membranes to cure fungal infections. It works by inhibiting the synthesis of ergosterol, a critical component of fungal cell membranes. It can also be used against certain species of Leishmania protozoa which are a type of unicellular parasites that also contain ergosterol in their cell membranes. In addition to its antifungal and antiparasitic actions, it also has some antibacterial properties. It is marketed in various formulations under various brand names.
Miconazole is also used in Ektachrome film developing in the final rinse of the Kodak E-6 process and similar Fuji CR-56 process, replacing formaldehyde. Fuji Hunt also includes miconazole as a final rinse additive in their formulation of the C-41RA rapid access color negative developing process.
It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.
Miconazole is mainly used externally for the treatment of athlete's foot, ringworm, and jock itch. Internal application is used for oral or vaginal thrush (yeast infection). The oral gel may also be used for the lip disorder angular cheilitis.
Unlike nystatin, some miconazole is absorbed by the intestinal tract when used orally (and possibly if used vaginally); this may lead to drug interactions.

Miconazole has recently gained some popularity as a hair-growth aid, although little evidence indicates its efficacy. Topical application of ketoconazole, a similar drug, has been shown to increase hair growth. However, oral administration of ketoconazole has also been shown to reduce hair growth in cases of hirsutism.
The solubilities of miconazole nitrate powder are 0.03% in water 0.76% in ethanol and up to 4% in acetic acid.
