Tigecycline: a review of a new glycylcycline antibiotic

Abstract

Tigecycline derived from minocycline. It is part of a new class of antibiotics called glycylcyclines. Tigecycline is given intravenously and has activity against a variety of gram-positive and gram-negative bacterial pathogens, many of which are resistant to existing antibiotics. Tigecycline successfully completed phase III trials in which it was at least equal to intravenous vancomycin and aztreonam to treat complicated skin and skin structure infections (cSSSI), and to intravenous imipenem and cilastatin to treat complicated intra-abdominal infections (cIAI). Tigecycline side effects are primarily digestive upset. It should be a valuable addition to the armamentarium to treat even the most resistant pathogens.
