Martifur 100 mg (Nitrofurantoin) – Uses, Dosage, Side Effects & Safety
Martifur 100 mg contains Nitrofurantoin, an antibiotic widely used for the treatment and prevention of urinary tract infections (UTIs), particularly infections caused by E. coli and other Gram-negative bacteria. Nitrofurantoin acts within the urinary tract, making it highly effective for bladder infections (cystitis). It works by damaging bacterial DNA, leading to bacterial death.
