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[edit]

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.[citation needed] 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.
