Pharmacology
Sitafloxacin has a broad spectrum of antibacterial activity against aerobic and anaerobic Gram-positive and Gram-negative bacteria, as well as atypical bacteria. The mechanism of action of Sitafloxacin involves inhibition of bacterial DNA gyrase and topoisomerase IV. Bactericidal activity of Sitafloxacin results from inhibition of these enzymes. The inhibitory activity of Sitafloxacin against these enzymes was higher than that of the other quinolone antimicrobials used as comparators. Sitafloxacin also has a potent inhibitory activity against enzymes from quinolone-resistant bacteria.
