Metronidazole (oral) — Nitroimidazole antimicrobial. Study the mechanism, listed uses and warnings from the US label on one sourced card.
Generic name
Metronidazole
Class
Nitroimidazole antimicrobial

In susceptible anaerobic bacteria, metronidazole is reduced to reactive intermediates that can inhibit DNA synthesis and degrade DNA, leading to bacterial death. Its precise mechanism of action is unclear.
Used for
Confirmed or otherwise specifically indicated Trichomonas vaginalis infection and selected partner-treatment settings; Acute intestinal amebiasis or amebic liver abscess; Serious infections caused by susceptible anaerobic bacteria
