Klion (metronidazole) possesses direct tri-chomonacidal and amebacidal activity against Trichomonas vaginalis, Giardia intestinalis, Entamoeba histolytica and anaerobic bacteria: Bacteroides species including the Bacteroides fragilis group (B. fragilis, B. distasonis, B. ovatus, B. thetaiotaomicron, and B. vulgatus) Fusobacterium species, and Helicobacter pylori (adjuvant).
Metronidazole works by entering bacterial and protozoal cells and interfering with their genetic material (DNA). It damages the Deoxyribonucleic acid (DNA) and also prevents the bacteria and protozoa from forming new DNA. This ultimately results in metronidazole killing the micro-organisms.
