Product Description

Hexamethonium dibromide is a medication that was used in the past as a ganglionic blocker to lower blood pressure by inhibiting the transmission of signals between nerves in the autonomic nervous system. It is a quaternary ammonium compound that is structurally similar to acetylcholine, a neurotransmitter that is involved in the transmission of nerve impulses between nerve cells in the autonomic nervous system.

Like other ganglionic blockers, hexamethonium dibromide works by binding to and blocking the nicotinic receptors on the postganglionic neurons of the autonomic nervous system. This blockade leads to a decrease in the activity of both the sympathetic and parasympathetic nervous systems, resulting in a decrease in blood pressure.

Hexamethonium dibromide is no longer used as a first-line treatment for hypertension due to its potential for serious side effects such as low blood pressure, constipation, dry mouth, blurred vision, and urinary retention. It may be used in certain clinical settings as a diagnostic tool to assess the function of the autonomic nervous system in certain disorders, such as orthostatic hypotension.

It is important to note that hexamethonium dibromide is a potent drug that should only be used under the supervision of a qualified healthcare professional. Proper safety precautions, such as monitoring for potential side effects and maintaining adequate hydration, should be taken when administering this medication.
