Ephedrine (EPH) is a sympathomimetic amine commonly used as a decongestant and to treat hypotension associated with regional anaesthesia. Chemically, it is an alkaloid derived from various plants in the genus Ephedra (family Ephedraceae). It is usually marketed as the ephedrine hydrochloride and ephedrine sulfate.
In traditional Chinese medicine, the herb ma huang (Ephedra sinica) contains ephedrine as its principal active constituent. The same is true of other herbal products containing extracts from Ephedra species. Nagayoshi Nagai was the first one to isolate ephedrine from Ephedra vulgaris in 1885. The substance called soma mentioned in old Hindu books such as the Rig Veda, may have been ephedra extract.
Chemistry
Ephedrine exhibits optical isomerism and has two chiral centres. By convention the enantiomers with opposite stereochemistry around the chiral centres are designated ephedrine, while pseudoephedrine has same stereochemistry around the chiral carbons. That is, (1R,2R)- and (1S,2S)-enantiomers are designated pseudoephedrine; while (1R,2S)- and (1S,2R)-enantiomers are designated ephedrine. More on [ Ephedrine ]
