Levonadifloxacin is the S-(-) isomer of the benzoquinolizine fluoroquinolone nadifloxacin and is two- to four-fold more active than the racemic mixture. Levonadifloxacin is a potent antibacterial agent against Gram-positive bacteria especially against methicillin resistance Staphylococcus aureus. It also possesses potent bactericidal activity against other resistant variants like quinolone-resistant Staphylococcus aureus, vancomycin and glycopeptide intermediate Staphylococcus aureus and vancomycin resistant Staphylococcus aureus. Intravenous dosage form developed to treat complicated skin and skin structure infections and has recently completed Phase III studies in India and Phase I studies in USA.
