Sudafed doesnt contain ephedrine, it contains pseudoephedrine. The difference between the two is that ephedrine has both the hydroxyl and methylamino group on the same side of the propyl chain whereas psudoephedrine has them on opposite sides.
This differenace makes pseudoephedrine (both the dextro- and levo- enantiomers) extremely weak stimulants, but doesnt take away from their ability to releive a congested nose
While im thinking of it Bojangles69, you must be talking of d-ephedrine. l-ephedrine is useless unless a person were making methamphetamine from it, but thats a different post for a different forum
