Tioconazole is an antifungal medication of the imidazole class used to treat infections caused by a fungus or yeast. It is marketed under the brand names Trosyd and Gyno-Trosyd (Pfizer). Tioconazole ointments serve to treat women's vaginal yeast infections.[1] They are available in one day doses, as opposed to the 7-day treatments more common in use in the past.

Tioconazole topical (skin) preparations are also available for ringworm, jock itch, athlete's foot, and tinea versicolor or "sun fungus".

Side effects

Side effects (for the women's formulas) may include temporary burning/irritation of the vaginal area, moderate drowsiness, headache similar to a sinus headache, hives, and upper respiratory infection. These side effects may be only temporary, and do not normally interfere with the patient's comfort enough to outweigh the end result.


Antimycotic imidazole derivative.

Tiaconazole synthesis:[2]

A displacement reaction between 1-(2,4-dichlorophenyl)-2-(1H-imidazol-1-yl)ethanol and 2-chloro-3-(chloromethyl)thiophene is performed.
