Ephedrine is a sympathomimetic alkaloid originally obtained from species of or prepared synthetically. Its action is similar to that of epinephrine (a catecholamine hormone secreted by the adrenal medulla and a neurotransmitter).
Its effects, although less powerful, are more prolonged, and it exerts action when administered orally, whereas epinephrine is effective only by injection. It is used as muscle relaxants, central nervous system and cardiac muscle stimulants in combination with others like theophylline.
It is used to prevent hypotension during spinal and infiltration anesthesia; and as a mydriatic. There are enantiomers in ephedrine structure. (1R,2S)- and (1S,2R)-enantiomers are designated ephedrine (opposite stereoisomerisms around the chiral center), whereas (1R,2R)- and (1S,2S)-enantiomers are designated pseudoephedrine. Commercial ephedrine is (-)-(1R,2S)-ephedrine [also called (-)-Ephedrine or L-ephedrine], while commercial pseudoephedrine enantiomer is (1S,2S)-pseudoephedrine [(+)-pseudoephedrine or D-pseudoephedrine].
Pseudoephedrine has less pressor action and fewer central stimulant effects than ephedrine. Pseudoephedrine is used as a nasal decongestant and a bronchodilator to relaxe and open the air passages to the lung to increase the flow of air, and thus is used in the treatment and/or prevention of symptoms of bronchial asthma and of reversible bronchospasm associated with chronic bronchitis and emphysema.
