Noroxin (Norfloxacin) is used to treat a variety of bacterial infections. It is effective against certain types of bacteria and is commonly used to treat urinary tract infections, prostate infections, and gastrointestinal infections caused by susceptible bacteria.

Norfloxacin belongs to a class of drugs known as quinolone antibiotics. This classification is important in understanding its mechanism of action and its effectiveness in stopping the growth of bacteria.

Norfloxacin works by inhibiting the activity of certain enzymes in bacteria, preventing them from replicating and spreading. By stopping the growth of bacteria, it helps the body's immune system to eliminate the infection.
