Clinical evaluation of mezlocillin

Abstract
The safety and efficacy of intravenous mezlocillin were determined in 25 patients with aerobic, anaerobic, and mixed infections. Included were pleuropulmonary, urinary tract, skin, and soft-tissue infections, osteomyelitis, and abdominal and breast abscess. Nineteen patients (76%) were cured without recurrence as determined by clinical and bacteriological parameters. In three, the infection recurred (12%); two patients failed (8%), and in one, it was indeterminate (4%). No serious adverse effects were noted except for severe thrombophlebitis in three (12%) patients. Our preliminary data suggest that mezlocillin is a safe (except for thrombophlebitis) and effective antibiotic in the treatment of aerobic anaerobic, and mixed infections.
