Metronidazole is a potent antibiotic and antiprotozoal medication widely used in the treatment of various infections, particularly those caused by anaerobic bacteria and certain protozoa. It works by entering the cells of microorganisms and disrupting their DNA synthesis, ultimately leading to cell death. Metronidazole is primarily prescribed for conditions such as bacterial vaginosis, trichomoniasis, and certain gastrointestinal infections.
