Comments

Ephedrine is a sympathomimetic amine, hypothesised to act principally as a β-adrenoceptor agonist. Natural ephedrine is used in Chinese traditional medicine as a treatment for asthma and bronchitis. Chemically, ephedirine can exist as four stereoisomers: the (1R,2S) and (1S,2R) pair of enantiomers is known as ephedrine ( with the INN racephedrine aknowledging the racemic mixture), while (1R,2R) and (1S,2S) pair is known as pseudoephedrine. The (1R,2S) isomer is also named (-)-ephedrine or D-ephedrine. The (1S,2S) isomer being (+)-ephedrine or L-ephedrine. Pseudoephedrine is much less active than ephedrine.
