could you please tell me the difference between pseudoephedrine and ephedrine? do they do the same thing?

User avatar Pseudoephedrine (a sympathomimetic) is an orally effective nasal decongestant with peripheral effects similar to epinephrine and central effects similar to, but less intense than, amphetamines. It directly stimulates alpha-adrenergic receptors of respiratory mucosa causing vasoconstriction, directly stimulates beta-adrenergic receptors causing bronchial relaxation, increased heart rate and contractility.
Ephidrine has similar effects however it works by releasing tissue stores of epinephrine and therby produces an alpha and beta adrenergic response, longer acting but less potent than epinephrine.
