Ornidazole is an antibiotic used to treat

protozoan infections.[1]: 1368  A synthetic nitroimidazole, it is commercially obtained from an acid-catalyzed reaction between 2-methyl-5-nitroimidazole and epichlorohydrin.[2]

Antimicrobial spectrum is similar to that of metronidazole and is more well tolerated;[1]: 1368  however there are concerns of lower relative efficacy.[3]

It was first introduced for treating trichomoniasis before being recognized for its broad anti-protozoan and anti-anaerobic-bacterial capacities.[4]: 1261  has also been investigated for use in Crohn's disease after bowel resection.[5]
