Ofloxacin is a broad-spectrum fluoroquinolone antibiotic used to treat a variety of bacterial infections, including respiratory tract infections, urinary tract infections, skin infections, and eye infections. It inhibits bacterial DNA gyrase and topoisomerase IV. Ofloxacin is approved for use worldwide and remains a commonly used antibiotic both systemically and as an ophthalmic agent.
