Comprehensive Review on Garenoxacin: Pharmacological Profile, Analytical Methods, and Clinical Application

This comprehensive review explores garenoxacin, a novel des-fluoro (6) quinolone antibiotic, highlighting its pharmacological properties, clinical applications, and analytical methodologies. Garenoxacin exhibits broad-spectrum antibacterial activity against both Gram-positive and Gram-negative organisms, including drug-resistant strains. Its mechanism involves dual inhibition of DNA gyrase and topoisomerase IV, making it a potent candidate for treating skin and soft tissue infections (SSSIs), respiratory tract infections, and other microbial conditions. The paper examines garenoxacin’s pharmacokinetics, protein binding. Pharmacodynamic analyses show that AUC/MIC ratios are critical for efficacy. Analytical techniques such as HPLC, UHPLC, RP-HPLC, and UV-spectrophotometry are discussed in the context of garenoxacin quantification and validation, with emphasis on ICH and QbD guidelines. Clinical cases and studies underscore its effectiveness, safety, and occasional adverse reactions, including hypersensitivity and fixed drug eruptions. The review also includes method development for pharmacokinetic studies and dosage form analysis, establishing garenoxacin’s significance in therapeutic and analytical fields.
