What is cholinergic agonist?

Cholinergic agonists are the name given to a group of medicines that mimic the actions of acetylcholine. Acetylcholine is one of the most common neurotransmitters in our body, and it has actions in both the central and peripheral nervous systems.

What are cholinergic agonists and classification of cholinergic agonists?

Cholinomimetics can be classified as: Direct-acting (receptor agonists), acting on muscarinic and nicotinic, and Indirect-acting (cholinesterase inhibitors), which, in turn, can be reversible or irreversible. Direct-acting cholinomimetics are drugs that act directly by stimulating cholinergic receptors.

How do cholinergic agonists work?

The direct-acting cholinergic agonists work by directly binding to and activating the muscarinic receptors. Examples of direct-acting cholinergic agents include choline esters (acetylcholine, methacholine, carbachol, bethanechol) and alkaloids (muscarine, pilocarpine, cevimeline).

Which medication is a cholinergic?

Cholinergic drugs are also used in control of glaucoma, a disease that is caused by increased pressure inside the eye. The most common drugs used for this purpose are demecarium (Humorsol) and echthiophate (Phospholine iodide).

What are cholinergic side effects?

The possible adverse effects of cholinergic drugs are: slow heart beat, possibly leading to cardiac arrest. muscle weakness, muscle cramps, and muscle pain. convulsions. weak breathing, inability to breath. increased stomach acid and saliva. nausea and vomiting. izziness, drowsiness, and headache.

What do cholinergic drugs do?

A cholinergic drug is an acetylcholine agonist that stimulates the parasympathetic nervous system and mimics a hormone found naturally in the body. This hormone controls digestion and muscle strength.

What are the effects of acetylcholine?

Rare (systemic) side effects of Acetylcholine include: slow heartrate. flushing. low blood pressure (hypotension) breathing difficulty. sweating.
