Newer quinolones in the treatment of continuous ambulatory peritoneal dialysis (CAPD) related infections

Abstract

Newer fluoroquinolones such as ciprofloxacin, pefloxacin, ofloxacin, enoxacin, and fleroxacin are potent antimicrobial agents against many gram-negative bacteria, including Pseudomonas aeruginosa species and staphylococci-sensitive or resistant to methicillin. They are almost completely absorbed when given orally, reaching therapeutic plasma and dialysate concentrations, and their long half lives permit infrequent dosing intervals. Clinical studies on fluoroquinolones efficacy in continuous ambulatory peritoneal dialysis (CAPD) infections, although not extensive, demonstrate good results. They are well tolerated and the adverse reactions, consisting mainly of gastrointestinal disturbance, were uncommon, mild, and reversible. The fluoroquinolones offer a promising alternative to standard parenteral treatments in CAPD patients, while their good oral bioavailability makes them attractive and convenient for both patients and hospital staff. However, they must be used with caution until we have more information and gain further experience.
