Levofloxacin has become a staple in the global API market, driven by its broad-spectrum efficacy and favorable safety profile. As a third-generation fluoroquinolone, it is widely used in both oral and intravenous formulations for respiratory, urinary, and skin infections. Demand remains strong, particularly in Asia and Latin America, where generic penetration is high and healthcare access is expanding.

Chemically, levofloxacin is the levo-isomer of ofloxacin, belonging to the fluoroquinolone class. It works by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication. This mechanism gives it bactericidal activity against a wide range of Gram-negative and Gram-positive pathogens.

Our levofloxacin is manufactured under strict GMP conditions and is available in high purity, meeting pharmacopeial standards including USP, EP, and BP. It is supplied as a white to off-white crystalline powder, suitable for tablet, capsule, and sterile injectable production.
