ABSTRACT

Background: The long-acting lipoglycopeptides dalbavancin and oritavancin possess excellent microbiologic activity against gram-positive bacteria and provide prolonged tissue exposure at sites of infection. Moreover, these antibiotics are well tolerated and do not require therapeutic drug monitoring. Methods: Pharmacokinetic/pharmacodynamic experiments ascertained that one to two doses of these long-acting agents can provide an extended period (≥6 weeks) of antimicrobial therapy. Results: Clinical studies subsequently found that microbiologic and clinical response rates with these agents were comparable to standard antibiotic agents used in the treatment of bone and joint infections. In addition, pharmacoeconomic analyses have discovered cost savings with the use of these antimicrobial agents in the treatment of serious deep-seated bacterial infections. Conclusions: Thus, these long-acting lipoglycopeptides offer potential for cost-effective outpatient parenteral antibiotic therapy of difficult to treat infections, such as osteomyelitis.
