In the outdated D/L system (+)-pseudoephedrine is also referred to as L-pseudoephedrine and (−)-pseudoephedrine as D-pseudoephedrine (in the Fisher projection then the phenyl ring is drawn at bottom).Often the D/L system (with small caps) and the d/l system (with lower-case) are confused. The result is that the dextrorotary d-pseudoephedrine is wrongly named D-pseudoephedrine and the levorotary l-ephedrine (the diastereomer) wrongly L-ephedrine. The IUPAC names of the two enantiomers are (1S,2S)- respectively (1R,2R)-2-methylamino-1-phenylpropan-1-ol. Synonyms for both are psi-ephedrine and threo-ephedrine. Pseudoephedrine is the International Nonproprietary Name of the (+)-form, when used as pharmaceutical substance. Society and culture
