It has also been investigated for use in Crohn's disease after bowel resection.[1] Synthesis is a straightforward reaction between 2-methyl-nitroimidazole and epichlorohydrin under acid catalyst conditions.[2] Mechanism of action and susceptible organismsAfter passive absorption into bacterium cell, the nitro group of ornidazole is reduced to an amine group by ferrodoxin-type redox systems. The formation of redox intermediate intracellular metabolites is believed to be the key component responsible for killing microorganisms. The drug is active against anaerobic bacteria including Peptostreptococcus, Clostridium, Bacteroides fragilis, Prevotella, Porphyromonas gingivalis, and Fusobacterium as well as protozoa including Entamoeba histolytica, Trichomonas vaginalis, and Giardia lamblia.[3] References1. ^{{cite journal |vauthors=Rutgeerts P, Van Assche G, Vermeire S, etal |title=Ornidazole for prophylaxis of postoperative Crohn's disease recurrence: a randomized, double-blind, placebo-controlled trial |journal=Gastroenterology |volume=128 |issue=4 |pages=856–61 |date=April 2005 |pmid=15825069 |doi= 10.1053/j.gastro.2005.01.010|url=http://linkinghub.elsevier.com/retrieve/pii/S0016508505000302}} {{Nucleic acid inhibitors}}{{Gynecological anti-infectives and antiseptics}}{{Agents against amoebozoa}}{{antiinfective-drug-stub}}{{genito-urinary-drug-stub}}2. ^{{cite journal|last1=Hoffer|first1=Max|last2=Grunberg|first2=Emanuel|title=Synthesis and antiprotozoal activity of 1-(3-chloro-2-hydroxypropyl)-substituted nitroimidazoles|journal=Journal of Medicinal Chemistry|volume=17|issue=9|year=1974|pages=1019–1020|issn=0022-2623|doi=10.1021/jm00255a026}} 3. ^http://webcache.googleusercontent.com/search?q=cache:OFkC_pjHLZ4J:www.panacea-biotec.com/product-pdf/Ocimix_28-11-2010.pdf 6 : Antiprotozoal agents|Disulfiram-like drugs|Poultry diseases|Nitroimidazole antibiotics|Organochlorides|Halohydrins |
