French pharmaceutical company Hoechst Marion Roussel (later Sanofi-Aventis) began phase II/III clinical trials of telithromycin (HMR-3647) in 1998. Telithromycin was approved by the European Commission in July 2001 and subsequently went on sale in October 2001. In the US, telithromycin received FDA approval on April 1, 2004 .

The Telithromycin is an organic compound with the formula C₄₃H₆₅N₅O₁₀. The IUPAC name of this chemical is (1R,2S,4R,6R,7R,8R,10S,13S,14S)-7-[(2S,3R,4S,6R)-4-(dimethylamino)-3-hydroxy-6-methyloxan-2-yl]oxy-13-ethyl-6-methoxy-2,4,6,8,10,14-hexamethyl-17-[4-(4-pyridin-3-ylimidazol-1-yl)butyl]-12,15-dioxa-17-azabicyclo[12.3.0]heptadecane-3,9,11,16-tetrone. With the CAS registry number 191114-48-4, it is also named as 2H-oxacyclotetradecino[4,3-d]oxazole-2,6,8,14(1H,7H,9H)-tetrone, 4-ethyloctahydro-11-methoxy-3a,7,9,11,13,15-hexamethyl-1-[4-[4-(3-pyridinyl)-1H-imidazol-1-yl]butyl]-10-[[3,4,6-trideoxy-3-(dimethylamino)-β-D-xylo-hexopyranosyl]oxy]-, (3aS,4S,7R,9R,10R,11S,13R,15S,15aR)-. The product's classification codes are Anti-Bacterial Agents; Anti-Infective Agents; Antibacterial; Antimicrobial. Besides, it is the first ketolide antibiotic to enter clinical use. It is used to treat mild to moderate respiratory infections.
