Pazufloxacin hydrochloride is primarily used as a broad-spectrum antibiotic in the treatment of various bacterial infections. It is effective against both Gram-positive and Gram-negative bacteria, making it suitable for treating respiratory tract infections, urinary tract infections, and skin infections. The compound is often administered intravenously, ensuring rapid delivery and absorption in severe or acute cases. Its mechanism of action involves inhibiting bacterial DNA gyrase and topoisomerase IV, which prevents bacterial DNA replication and ultimately leads to cell death. Due to its potent antibacterial activity, it is particularly valuable in hospital settings for managing infections caused by multidrug-resistant pathogens. However, its use is typically reserved for cases where other antibiotics have proven ineffective, to minimize the risk of developing resistance.
