NameTelithromycin
Groups approved
DescriptionTelithromycin, 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.
