Ornidazole is an antiprotozoal and antibacterial agent, a derivative of 5-nitroimidazole. Active against Trichomonas vaginalis, Entamoeba histolytica, Giardia lamlia (Gardia intestinalis), as well as some anaerobic bacteria such as Bacteroides, Clostridium spp., Fusobacterium spp. and anaerobic cocci.

According to the mechanism of action, ornidazole is a DNA-tropic drug with selective activity against microorganisms that have enzyme systems capable of reducing the nitro group and catalyzing the interaction of proteins of the feridoxin group with nitro compounds.

After the penetration of the drug into the microbial cell, the mechanism of its action is due to the restoration of the nitro group under the influence of nitroreductases of the microorganism and the activity of the already reduced nitroimidazole.

Recovery products form complexes with DNA, causing its degradation, disrupt the processes of DNA replication and transcription. In addition, the metabolic products of the drug have cytotoxic properties and disrupt the processes of cellular respiration.
