General description
Clinafloxacin is a fluoroquinolone antibiotic with a broad range of bactericidal activity, used in the treatment of gynaecologic and urinary infections. It inhibits bacterial DNA gyrase enzyme which is responsible for synthesis, replication, repair and transcription.
Application
Clinafloxacin may be used as a reference standard for the determination of clinafloxacin in urine samples of rat and human by capillary zone electrophoresis.

A total of 33 Stenotrophomonas maltophilia clinical isolates were tested for their susceptibility to clinafloxacin in comparison with ciprofloxacin, levofloxacin, moxifloxacin, nalidixic acid, norfloxacin, sparfloxacin and trovafloxacin. The MIC(50) and MIC(90) were as follows: ciprofloxacin 4 and 64 microg/mL; clinafoxacin

In an open-label, phase 3, randomized, multicenter study, clinafloxacin (200 mg/d) was compared to ceftriaxone (2 g/d; with or without erythromycin) in 527 patients with acute community-acquired bacterial pneumonia (CAP). Primary efficacy parameters were clinical cure rate and microbiologic eradication

The in vitro activity of clinafloxacin was studied in comparison with ciprofloxacin, levofloxacin, moxifloxacin, nalidixic acid, sparfloxacin and trovafloxacin against Acinetobacter baumannii clinical isolates. Clinafloxacin showed a MIC(90) of 4 mg/L, whereas the remaining quinolones showed a MIC(90) equal to
