Bethanidine is a post-ganglionic adrenergic neurone-blocking agent which exerts a marked postural hypotensive effect. The precise mechanism whereby bethanidine causes blockade of adrenergic neurones is unknown. An initial sympathomimetic effect has been demonstrated in man and animals, possibly due to release of catecholamines.

The effects of bethanidine sulphate, a pharmacological analog of the cardiac antibrillatory drug, bretylium tosylate, were studied on action potentials (APs) and K+, Na+, and Ca2+ currents of single cultured embryonic chick heart cells using the whole-cell current clamp and voltage clamp technique. Extracellular application of bethanidine (0.3 mM) increased the overshoot and the duration of the APs and greatly decreased the outward K+ current (IK) and potentiated the inward fast Na+ currents (INa) and the inward slow calcium current (ICa). However, intracellular introduction of bethanidine (0.1 mM) blocked INa.
