Teicoplanin.

Teicoplanin, a new glycopeptide antibiotic similar to vancomycin, has proved effective in the treatment of various gram-positive infections in both the normal and the immunocompromised host. In vitro activity against most gram-positive organisms is equal to or greater than that of vancomycin. In both open and comparative clinical trials, teicoplanin has been well tolerated, rarely prompting discontinuation of treatment. Nephrotoxicity caused by teicoplanin is uncommon, even when used concomitantly with aminoglycosides or cyclosporin A. Favorable pharmacokinetics allow for intramuscular administration as well as intravenous bolus dosing, and, after appropriate loading doses, maintenance therapy may be given on a once-daily basis. The combination of all of these factors makes teicoplanin an effective, safe alternative to vancomycin in the treatment of gram-positive infections.
