Dược Lực Học : Tigecycline is the first clinically-available drug in a new class of antibiotics called the glycylcyclines. Glycylcyclines are a new class of antibiotics derived from tetracycline. These tetracycline analogues are specifically designed to overcome two common mechanisms of tetracycline resistance, namely resistance mediated by acquired efflux pumps and/or ribosomal protection. Glycylcycline antibiotics have a similar mechanism of action as tetracycline antibiotics. Both classes of antibiotics bind to the 30S ribosomal subunit to prevent the amino-acyl tRNA from binding to the A site of the ribosome. However, the glycylcyclines appear to bind more effectively than the tetracyclines.
Cơ Chế Tác Dụng : Tigecycline is a glycylcycline antibiotic developed and marketed by Wyeth under the brand name Tygacil. It was given a U.S. Food and Drug Administration (FDA) fast-track approval and was approved on June 17, 2005. It was developed in response to the growing prevalence of antibiotic resistance in bacteria such as Staphylococcus aureus. Tigecycline, a glycylcycline, inhibits protein translation in bacteria by binding to the 30S ribosomal subunit and blocking entry of amino-acyl tRNA molecules into the A site of the ribosome. This prevents incorporation of amino acid residues into elongating peptide chains. Tigecycline carries a glycylamido moiety attached to the 9-position of minocycline. The substitution pattern is not present in any naturally occurring or semisynthetic tetracycline and imparts certain microbiologic properties to tigecycline. Tigecycline is not affected by the two major tetracycline resistance mechanisms, ribosomal protection and efflux. Accordingly, tigecycline has demonstrated in vitro and in vivo activity against a broad spectrum of bacterial pathogens. There has been no cross resistance observed between tigecycline and other antibiotics. Tigecycline is not affected by resistance mechanisms such as beta-lactamases (including extended spectrum beta-lactamases), target site modifications, macrolide efflux pumps or enzyme target changes (e.g. gyrase/topoisomerase). In vitro studies have not demonstrated antagonism between tigecycline and other commonly used antibacterial drugs. In general, tigecycline is considered bacteriostatic.
Dược Động Học :

▧ Protein binding :
71% to 89%
▧ Metabolism :
Tigecycline is not extensively metabolized. In vitro studies with tigecycline using human liver microsomes, liver slices, and hepatocytes led to the formation of only trace amounts of metabolites. A glucuronide, an N-acetyl metabolite, and a tigecycline epimer (each at no more than 10% of the administered dose) are the primary metabolites.
▧ Half Life :
27-43 hours
Độc Tính : Since glycylcyclines are similar to tetracyclines, they share many of the same side effects and contraindications as tetracyclines. These side effects may include nausea/vomiting, headache, photosensitivity, discoloration of growing teeth, and fetal damage.
Chỉ Định : For the treatment of infections caused by susceptible strains of the designated microorganisms in the following conditions: Complicated skin and skin structure infections caused by Escherichia coli, Enterococcus faecalis (vancomycin-susceptible isolates only), Staphylococcus aureus (methicillin-susceptible and -resistant isolates), Streptococcus agalactiae, Streptococcus anginosus grp. (includes S. anginosus, S. intermedius, and S. constellatus), Streptococcus pyogenes and Bacteroides fragilis. Complicated intra-abdominal infections caused by Citrobacter freundii, Enterobacter cloacae, Escherichia coli, Klebsiella oxytoca, Klebsiella pneumoniae, Enterococcus faecalis (vancomycin-susceptible isolates only), Staphylococcus aureus (methicillin-susceptible isolates only), Streptococcus anginosus grp. (includes S. anginosus, S. intermedius, and S. constellatus), Bacteroides fragilis, Bacteroides thetaiotaomicron, Bacteroides uniformis, Bacteroides vulgatus, Clostridium perfringens, and Peptostreptococcus micros.
Tương Tác Thuốc :
  • Acenocoumarol Tigecycline may increase the anticoagulant effect of acenocoumarol.
  • Anisindione Tigecycline may increase the anticoagulant effect of anisindione.
  • Bexarotene Tigecycline may enhance the adverse/toxic effect of Retinoic Acid Derivatives. The development of pseudotumor cerebri (intracranial hypertension) is of particular concern. Avoid this combination.
  • Dicoumarol Tigecycline may increase the anticoagulant effect of dicumarol.
  • Tretinoin Demeclocycline may increase the adverse effects of oral Tretinoin. Increase risk of pseudotumour cerebri. Concurrent therapy should be avoided.
  • Warfarin Tigecycline may increase the serum concentration of warfarin.
