Morphology

pseudoephedrine = ephedrine (semi-transparent) = pseudo + ephedrine

The word is transparently built with pseudo- plus the base 'ephedrine', but the medical meaning is specialized and not fully predictable from the parts alone.

Etymology

Pseudoephedrine begins with pseudo- meaning 'false' and ends with ephedrine, a name from the plant Ephedra, so the name suggests a chemical that is 'like' ephedrine but not the same. So, pseudoephedrine is the drug used as a decongestant in cold and allergy medicines and is sometimes controlled because it can be misused.
