Pharmachologic effect
Levofloxacin is a broad-spectrum antimicrobial bactericidal agent from the group of fluoroquinolones. Blocks DNA gyrase (topoisomerase II) and topoisomerase IV, disrupts supercoiling and cross-linking of DNA breaks, suppresses DNA synthesis, causes profound morphological changes in the cytoplasm, cell wall and membranes of bacteria.
