Description

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.
