Tinidazole is a 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 and is a prominent member of the nitroimidazole antibiotic class.^[1]

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.

Uses

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 intolerance. Tinidazole may also be used to treat a variety of other bacterial infections (e.g., as part of combination therapy for Helicobacter pylori eradication protocols).^[2]

Side effects

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

Half-life

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