Nitrofurantoin 100mg Sustained Release (SR) capsules are an oral antibiotic formulation primarily used for the treatment and prevention of urinary tract infections (UTIs). Nitrofurantoin is a broad-spectrum antibacterial agent that works by inhibiting bacterial enzyme systems and damaging bacterial DNA, leading to the destruction of infection-causing organisms in the urinary tract. The sustained-release formulation ensures gradual release of the active ingredient, maintaining effective drug levels in the urine for an extended period. This helps improve treatment compliance and reduces the frequency of dosing while minimizing gastrointestinal discomfort. Nitrofurantoin is particularly effective against common UTI-causing bacteria such as Escherichia coli, Enterococcus, Staphylococcus saprophyticus, and certain strains of Klebsiella and Enterobacter. It is commonly prescribed for: Acute uncomplicated urinary tract infections Recurrent UTI prophylaxis Cystitis (bladder infection)
