levofloxacin + moxifloxacin

Levofloxacin + moxifloxacin is a combination of two fluoroquinolone antibiotics, levofloxacin and moxifloxacin. Both agents act by inhibiting bacterial DNA gyrase and topoisomerase IV, enzymes essential for DNA replication, transcription, repair, and recombination in bacteria. This dual inhibition leads to the disruption of bacterial cell division and ultimately results in cell death. The combination may be considered for use in multidrug-resistant infections such as tuberculosis when sensitivity to both drugs is confirmed or when other options are limited. Each drug has a broad antibacterial spectrum covering respiratory tract pathogens, Mycobacterium tuberculosis (including multidrug-resistant strains), skin/soft tissue infections, urinary tract infections, and more[2][3][4][5][6][7][8][9][10]. Moxifloxacin generally exhibits greater bactericidal activity against Mycobacterium tuberculosis compared to levofloxacin[3][4]. Both drugs are used individually but can be combined under special clinical circumstances.
