Ephedrine has the same action as epinephrine but has slightly different properties. It is similar to amphetamines in that ephedrine causes noradrenaline release leading to catecholaminergic receptor stimulation. Ephedrine has a lower potency but longer duration of action when compared with epinephrine. It also has more pronounced CNS effects.
