Mechanism Of Action and Pharmacodynamic Effects
Guanethidine is a substrate of the norepinephrine transporter, NET (SLC6A2). The drug is transported into storage granules in sympathetic neurones in place of endogenous ligand, and thereby decreases teh quantity of norepinephrine available for release across the synapse. This action reduces neurotransmitter release, subsequent postganglionic adrenoceptor activation and ultimately reduces arteriolar vasoconstriction. See the DrugBank link for further details.
