The Efficacy and Safety of Tigecycline for the Treatment of Complicated Intra-Adominal Infections - The European Experience

AbstractThe polymicrobial nature of complicated intra-abdominal infections makes these infections particularly challenging to treat. The initial selection of antimicrobial therapy is therefore extremely important. Inappropriate empiric antimicrobial therapy has been shown to delay clinical resolution, increase length of hospital stay, and increase the risk of mortality. In addition, the increasing frequency with which resistant isolates (e.g., extended spectrum beta-lactamases [ESBLs]) are recovered from patients mandates that empiric antimicrobial therapy covers these difficult-to-treat organisms.Here, we assessed the efficacy of a new antimicrobial agent, tigecycline. This is a combined analysis of data from the European sites that participated in two Phase III, double-blind trials to evaluate the efficacy and safety of tigecycline, versus that of imipenem/cilastatin, in adults with complicated intra-abdominal infections. Patients received either tigecycline (initial dose of 100 mg, followed by 50 mg in...
