Cholinergic Agonists and Antagonists

These flashcards cover key concepts about cholinergic agonists and antagonists, including definitions of relevant terms and examples.

Cholinergic Drug

A drug that binds and activates the acetylcholine receptor.

Anticholinergic Drug

A drug that blocks the acetylcholine receptor or its downstream actions.

Parasympathomimetics

Drugs that stimulate or mimic the parasympathetic nervous system.

Direct-Acting Cholinergic Drugs

Cholinergic drugs that act on receptors to activate tissue response.

Indirect-Acting Cholinergic Drugs

Drugs that inhibit the enzyme cholinesterase, allowing acetylcholine to persist.

Muscarinic Receptors

Cholinergic receptors that stimulate smooth muscles.

Nicotinic Receptors

Cholinergic receptors that stimulate skeletal muscles.

Cholinesterase Inhibitors

Substances that prevent the breakdown of acetylcholine by inhibiting cholinesterase.

Bethanechol Chloride

An example of a direct acting cholinergic drug.

Acetylcholine

The neurotransmitter mimicked by cholinergic drugs.
