Pharmacokinetics, Pharmacodynamics, and Tolerability Profile of Clinafloxacin

  • Charles W. Stratton
Review Article


Clinafloxacin is a broad-spectrum and highly potent member of the fluoro-quinolone class of antibiotics, with enhanced activity against difficult-to-treat Gram-negative, Gram-positive, and anaerobic pathogens. It appears that the most important factor in terms of structure-activity is the chloride atom at the C-8 position. Clinafloxacin has a tolerability profile that is similar to that of other quinolones. Structure-tolerability issues related to the C-8 halogen, such as phototoxicity, should not be a major problem for an antimicrobial agent used for nosocomial infections in hospitalised patients. Similar class-related tolerability issues of the quinolone class of antimicrobial agents, such as tendinitis, should not be an important issue in hospitalised patients.

The activity of clinafloxacin against multidrug-resistant nosocomial pathogens and anaerobes suggests that this agent would be well suited for empirical therapy of nosocomial infections in seriously ill patients. Initial in vivo animal studies have confirmed that the enhanced in vitro activity of clinafloxacin against difficult-to-treat nosocomial pathogens results in increased in vivo efficacy. The success in animal models has led to the current series of ongoing clinical trials. Published data from these studies to date have confirmed the efficacy of clinafloxacin against difficult-to-treat nosocomial pathogens.
