💊 Profile

Pefloxacin is a fluoroquinolone antibacterial with actions and uses similar to those of ciprofloxacin. It also has bactericidal activity against Mycobacterium leprae and has been tried in the treatment of leprosy. Pefloxacin has a longer plasma half-life than ciprofloxacin (about 8 to 13 hours) and is also extensively metabolised, the principal metabolite being N-desmethylpefloxacin. Pefloxacin is given orally or by intravenous infusion as the mesilate in the treatment of susceptible infections. Doses are expressed in terms of the base; pefloxacin mesilate 558.5 mg is equivalent to about 400 mg of pefloxacin. The usual dose is 400 mg twice daily. A single oral dose of 800 mg may be used in the treatment of gonococcal urethritis in men and acute uncomplicated cystitis in women. Fluoroquinolones have caused adverse effects on the musculoskeletal system and in the case of pefloxacin this has led to restrictions in some countries.
