Rufloxacin hydrochloride is primarily used as an antibacterial agent in the treatment of various infections. It is effective against a range of gram-negative and gram-positive bacteria, making it suitable for respiratory tract infections, urinary tract infections, and skin infections. The compound works by inhibiting bacterial DNA gyrase, preventing DNA replication and ultimately leading to bacterial cell death. Its broad-spectrum activity and oral bioavailability make it a practical option for outpatient treatment. Additionally, it is sometimes employed in cases where other antibiotics have proven ineffective due to resistance. Proper dosage and adherence to treatment regimens are essential to minimize the risk of developing bacterial resistance.
