Metronidazole
A nitroimidazole antimicrobial developed in France and described in 1959 as a treatment for Trichomonas vaginalis; today it is used against many protozoa and anaerobic bacteria. This family brings together the active ingredient, pharmacopoeial impurities, metabolites, labelled standards, nitrosamines and other impurities.
Did you know?It descends from azomycin, a natural antibiotic with a nitroimidazole ring described in Japan in 1953: by modifying its structure, chemists arrived at metronidazole.
