Ephedrine receptors
WebPseudoephedrine is a mixed-acting decongestant, which activates α- and β-adrenergic receptors directly by binding to the receptor itself, and indirectly by causing norepinephrine release in synaptic nerve terminals. Pseudoephedrine is also used illicitly in the production of methamphetamine. WebEphedrine is a sympathomimetic amine. The principal mechanism of its action relies on its indirect stimulation of the adrenergic receptor system, which is part of the sympathetic nervous system ( SNS ), by increasing the activity of noradrenaline at the post-synaptic α- and β-receptors.
