Abstrakt: Objective: Oritavancin is a lipoglycopeptide antibiotic approved for use in acute bacterial skin and skin structure infections as a single 1200-mg parenteral dose. Because of oritavancin's long half-life and broad gram-positive activity, interest in its use for other infections is high.
Methods: This study is a retrospective cohort evaluation of patients receiving oritavancin at a single academic medical center. All patients receiving more than one dose of oritavancin were included. Patients were excluded if therapy was interrupted by more than 14 days. Efficacy, defined a priori as clinical success, improvement, or failure, and adverse drug effect outcomes were collected.
Results: Seventeen patients received multiple oritavancin doses (range 2-18 doses) for the treatment of complicated infections including osteomyelitis, surgical site infection, intravascular infections, and pneumonia. All patients achieved clinical success or improvement with oritavancin. Four patients (24%) had an adverse event requiring oritavancin discontinuation that reversed rapidly.
Conclusions: Off-label oritavancin use may be a safe and effective alternative to daily antibiotic infusions to treat complicated infectious disease processes. This study is limited by small sample size and retrospective design, but it provides information on using oritavancin in these complex gram-positive infections.
