Pseudoephedrine is a sympathomimetic drug of the phenethylamine and amphetamine chemical classes. It may be used as a nasal/sinus decongestant, as a stimulant, or as a wakefulness-promoting agent in higher doses.

Pseudoephedrine is closely related in structure to methamphetamine, although its CNS actions are much less potent and also longer-lasting than those of the amphetamines. Its peripheral stimulant actions are similar to but less powerful than those of epinephrine (adrenaline), a hormone produced in the body by the adrenal glands.
