How Nitrofurantoin 50 mg Works
Nitrofurantoin 50 mg works by disrupting bacterial cell processes, specifically targeting bacterial enzymes involved in the synthesis of DNA, RNA, and cell walls. This inhibition halts bacterial growth and leads to bacterial death. The antibiotic action is primarily localized in the urinary tract because the drug rapidly concentrates in the urine, making it highly effective against urinary pathogens.
Its selective activity ensures minimal impact on the beneficial bacteria found elsewhere in the body, contributing to a lower rate of resistance and side effects compared to some other antibiotics.
