Abstract

Biapenem is an injectable carbapenem antibiotic. A clinical study was designed to evaluate its efficacy and safety in the treatment of respiratory and urinary infections compared to imipenem/cilastatin.A total of 216 patients with respiratory or urinary tract infections were enrolled into this multicenter, open-label, randomized controlled clinical study. Each patient was randomly assigned to either the treatment or control group; 106 patients in each group were included in the ITT analyses. The patients were given biapenem 300 mg or imipenem/cilastatin 500 mg/500 mg two or three times daily, i.v. g.t.t. for 7-14 days according to their conditions.The cure and effective rates were 67.92 and 88.68% in the biapenem group and 76.02 and 93.40% in the imipenem/cilastatin group, the bacterial eradication rates were 93.83 and 98.82%, and the adverse-event rates were 6.54 and 7.41%, respectively. There were no significant differences between the two groups (p > 0.05).Biapenem is as effective and well-tolerated as imipenem/cilastatin for the treatment of intermediate and severe bacterial infections.Copyright © 2010 S.
