http://linked.open...gbank/description
  • Telithromycin, a semi-synthetic erythromycin derivative, belongs to a new chemical class of antibiotics called ketolides. Ketolides have been recently added to the macrolide-lincosamide-streptogramin class of antibiotics. Similar to the macrolide antibiotics, telithromycin prevents bacterial growth by interfering with bacterial protein synthesis. Telithromycin binds to the 50S subunit of the 70S bacterial ribosome and blocks further peptide elongation. Binding occurs simultaneously at to two domains of 23S RNA of the 50S ribosomal subunit, domain II and V, where older macrolides bind only to one. It is used to treat mild to moderate respiratory infections. (en)

http://linked.open...mechanismOfAction
  • Telithromycin acts by binding to domains II and V of 23S rRNA of the 50S ribosomal subunit. By binding at domain II, telithromycin retains activity against gram-positive cocci (e.g. Streptococcus pneumoniae) in the presence of resistance mediated by methylases (erm genes) that alter the binding site at domain V. Telithromycin may also inhibit the assembly of nascent ribosomal units. Compared to erythromycin A, telithromycin binds to the 23S rRNA with 10 times greater affinity in erythromycin-susceptible organisms and 25 times greater affinity in macrolide-resistant strains. This increased binding affinity may be conferred by the C11-12 carbamate side chain of telithromycin. The side chain appears to maintain binding at domain II in the presence of resistance mediated by alterations in domain V. (en)

http://linked.open...outeOfElimination
  • The systemically available telithromycin is eliminated by multiple pathways as follows: 7% of the dose is excreted unchanged in feces by biliary and/or intestinal secretion; 13% of the dose is excreted unchanged in urine by renal excretion; and 37% of the dose is metabolized by the liver. (en)
http://linked.open...drugbank/toxicity
  • LD50>2000 mg/kg (PO in rats). Adverse effects are similar to those of clarithormycin and erithromycin and include diarrhea, nausea, vomiting, loose stools, abdominal pain, flatulence and dyspepsia. It may also cause dizziness, headache and taste disturbances. (en)
