Pseudoephedrine
An ephedra alkaloid and stereoisomer of ephedrine, isolated in Germany in 1889 by the chemists Ladenburg and Oelschlägel: it narrows the blood vessels of the nasal lining and is used as a decongestant for a blocked nose due to colds and sinusitis. This family brings together the active ingredient, pharmacopoeial impurities, labelled standards, nitrosamines and other impurities.
Did you know?Ephedra, or ma huang, has been used in traditional Chinese medicine for thousands of years, but the decongestant effect of pseudoephedrine was only described in 1927, through animal experiments.
