How Ronifur S 75 mg/200 mg Suspension Works

Ronifur S 75 mg/200 mg Suspension works through the combined actions of its two active ingredients to treat bacterial and parasitic infections of the digestive tract. Metronidazole targets anaerobic bacteria and certain protozoan parasites. Inside these microorganisms, it is converted into active compounds that form harmful free radicals, which damage their DNA and lead to the death of the microorganisms, helping clear the infection.   Furazolidone works mainly in the intestines by interfering with essential enzyme systems that bacteria and certain parasites need to survive. It also inhibits monoamine oxidase (MAO), which is why certain antidepressants and foods high in tyramine should be avoided during treatment. Together, these two ingredients provide broad coverage against susceptible bacteria and parasites that cause intestinal infections.
