Application

Hexamethonium bromide has been used:
  • as an autonomic ganglia-blocking agent to study its effects on whisker movement in rats
  • as a nicotinic receptor antagonist to study its effects on antigen-induced arthritis (AIA) progression in mice
  • as a non-selective ganglionic nicotinic acetylcholine receptor (nAChR) antagonist to study its effects on cytisine-induced autonomic cardiovascular responses in mice

Biochem/physiol Actions

Hexamethonium bromide is a nicotinic acetylcholine receptor (nAChR) antagonist. It preferentially blocks nicotinic receptors at autonomic ganglia. It can cross the blood-brain barrier only at high doses.

Nicotinic cholinergic receptors mediate autonomic transmission at ganglia. However, whether different subtypes of nicotinic cholinergic receptors expressed in autonomic ganglia elicit distinct roles in mediating sympathetic and parasympathetic regulations remain to be defined. In this study, we observed that different
