PPT-Cholinergic Antagonists Cholinergic antagonist is a general term for agents

that bind to cholinoceptors muscarinic or nicotinic and prevent the effects of acetylcholine ACh and other cholinergic agonists The most clinically useful of these agents are selective . Muscarinic Agonists and Antagonists. Cholinergic Drugs. Agents that influence the activity of cholinergic receptors. Most mimic or block the actions of acetylcholine.. Cholinesterase inhibitors . Indirectly prevent the breakdown of acetylcholine. Cholinergic Agonists Direct-Acting Cholinomimetics Direct-Acting Cholinergic Agonists (N & M) Cholinergic agonists (parasympathomimetics) mimic the effects of ACh on cholinoceptors. These agents broadly classified into Chapter 14 Drugs Affecting The Nervous System The nervous system controls, directs and coordinates bodily functions 2 main divisions of the nervous system: Central Nervous System (CNS) - brain and spinal cord Week 1.
