The cholinergic action in the peripheral nerve function is considered to be of two types: (1) The rnuscarinic action of acetylcholine (ACh) occurs in pastganglionic parasympathetic and some sympathetic nerve terminals. Cholinomimetics are classified as direct-acting drugs, that is, drugs that activate the receptor site by mimicking the effects of Ach, and as indirectly acting drugs that prevent the enzyme cholinesterase (AChE) from hydrolyzing ACh at the receptor site. Pharmacology. Pilocarpine is a widely used cholinomimetic that primarily acts on muscarinic receptors. glands and vessels of skeletal muscles.
