Racephedrine, also known as racemic ephedrine and sold under the brand names Efetonina and Ephoxamine among others, is the racemic form of ephedrine which has been used as a bronchodilator to treat asthma.^{[1][2][3][4][5]} More specifically, it is a racemic mixture of (1R,2S)- and (1S,2R)-enantiomers.^[3] Conversely, ephedrine is the enantiopure (1R,2S)-enantiomer.^[1] Racephedrine has been marketed for medical use in Italy.^[1] Like ephedrine, racephedrine is a releasing agent of norepinephrine and to a much lesser extent of dopamine.^[6][7][8][9] Both ephedrine enantiomers are active in this regard, but ephedrine ((1R,2S)-ephedrine) has greater potency than (1S,2R)-ephedrine.^[6][7][8][9]
