Flagyl
Flagyl, the brand name for Metronidazole, is an antibiotic and antiprotozoal medication used to treat a variety of bacterial and parasitic infections. It is commonly prescribed for infections of the digestive system, reproductive organs, skin, and respiratory tract. Flagyl is particularly effective against anaerobic bacteria (bacteria that do not need oxygen to grow) and certain parasites, making it a versatile treatment for conditions like bacterial vaginosis, trichomoniasis, and infections caused by Clostridium difficile. It is available in oral, topical, and intravenous forms, depending on the type and severity of the infection.

Comprehensive Drug Guide
How Does Flagyl Work?
Flagyl works by entering the cells of the bacteria or parasites and interfering with their DNA synthesis, preventing them from multiplying. By damaging the DNA, Flagyl causes the death of the harmful organisms. This mechanism makes it effective against anaerobic bacteria and certain protozoa, which are often resistant to other antibiotics.
