Ganglioplegic

A ganglionic blocker (or ganglioplegic) is a type of medication that inhibits postganglionic transmission, primarily by acting as a nicotinic antagonist.[1]

Because ganglionic blockers block the parasympathetic nervous system and sympathetic nervous system, the effect of these drugs depends upon the dominant tone in the organ system.[2]

Examples

The first ganglion-blocker to be used clinically was tetraethylammonium, although it was soon superseded by better drugs.[3] Other examples include hexamethonium, pentolinium, mecamylamine, trimetaphan, and pempidine.

Others include:[4]

Uses

Ganglionic blockers are used less frequently now than they were in the past, because more selective agents are now available. However, they are still used in some emergency situations, such as aortic dissection or autonomic dysreflexia.
