Pharmacological action of
Metronidazole belongs to 5-nitroimidazoles and has a wide spectrum of activity against anaerobic microorganisms Peptostreptococcus species, Clostridium spp., Bacterioides spp., Prevevellaella, Prevellaella pella, Prevellaella pella, Prevellaella, Prevellaella, Prevellaella, pella bellaella . Suppresses the development of protozoa – Trichomonas vaginalis, Giardia intestinalis (Lamblia intestinalis), Entamoeba histolytica. The mechanism of action is the biochemical reduction of the 5-nitro group of metronidazole by intracellular transport proteins of anaerobic microorganisms and protozoa. The reduced 5-nitro group of metronidazole interacts with the deoxyribonucleic acid of cells, inhibiting the synthesis of their nucleic acids, which leads to the death of microorganisms.
