Indirectly acting cholinomimetic agents
Indirectly acting cholinomimetic agents do not themselves activate acetylcholine receptors. They exert their effects by increasing the concentration of endogenous acetylcholine in contact of the cholinergic receptors. Acetylcholine stimulates the receptors and is responsible for the elicited effects.
This rise in the acetylcholine level can result either from an increase in its synthesis and of its release, or of an inhibition of its destruction.
