Abstract
The chemistry, microbiology, pharmacokinetics, clinical efficacy, and adverse effect profile of teicoplanin are reviewed and, where appropriate, compared with vancomycin. Teicoplanin is a glycopeptide antibiotic with potent bactericidal activity against a wide variety of aerobic and anaerobic gram-positive bacteria. In contrast to the structurally related vancomycin, teicoplanin has a prolonged elimination half-life of approximately 60 hours and it may be safely administered by the intramuscular route. Adverse effects of teicoplanin include ototoxicity, nephrotoxicity, skin rash, eosinophilia, neutropenia, and transient elevation of serum aminotransferases. Teicoplanin may be beneficial as an alternative to vancomycin for patients with poor vascular access and in those requiring long-term outpatient therapy. The role of teicoplanin in the treatment and prophylaxis of gram-positive infections will ultimately depend on its unfolding safety and efficacy profile.
