Flagyl 400 Tablet contains Metronidazole, a well-known antibiotic and antiprotozoal agent used to treat a wide range of bacterial and parasitic infections. It effectively combats infections in the liver, stomach, intestines, brain, heart, lungs, bones, vagina, and skin.

Metronidazole works by killing bacteria and protozoa that cause infection, helping the body recover and preventing the spread of infection. It is also effective in managing anaerobic bacterial infections and certain sexually transmitted infections.

How Flagyl Works

Metronidazole enters bacterial and protozoal cells, where it disrupts their DNA synthesis and nucleic acid formation. This leads to cell death and prevents the microorganisms from multiplying.
It is particularly effective against anaerobic bacteria and protozoa, making it a versatile treatment for mixed or deep-seated infections.
