Tinidazole is an anti-parasitic drug used against protozoan infections. It is widely known throughout Europe and the developing world as a treatment for a variety of amoebic and parasitic infections. It was developed in 1972. A derivative of 2-methylimidazole, it is a prominent member of the nitroimidazole antibiotics.

Tinidazole is marketed by Mission Pharmacal under the brand name Tindamax, by Pfizer under the names Fasigyn and Simplotan, and in some Asian countries as Sporinex.

A large body of clinical data exists to support use of tinidazole for infections from amoebae, giardia, and trichomonas, just like metronidazole. Tinidazole may be a therapeutic alternative in the setting of metronidazole tolerance. Tinidazole may also be used to treat a variety of other bacterial infections (e.g., as part of combination therapy for ).

Drinking alcohol while taking tinidazole causes an unpleasant disulfiram-like reaction, which includes nausea, vomiting, headache, increased blood pressure, flushing, and shortness of breath.

Elimination half-life is 13.2 ± 1.4 hours. Plasma half-life is 12 to 14 hours.
