Ontology: Carbachol (C0006945)

Definition (NCI) A synthetic choline ester and a positively charged quaternary ammonium compound. Carbachol is a parasympathomimetic that mimics the effect of acetylcholine on both the muscarinic and nicotinic receptors. This drug is administered ocularly to induce miosis to reduce intraocular pressure in the treatment of glaucoma. Carbachol is also used to stimulate micturition by contraction of detrusor muscle. This drug may cause hypotension, bradycardia, nausea, vomiting, bronchospasm, and abdominal cramps.
Definition (MSH) A slowly hydrolyzed cholinergic agonist that acts at both muscarinic and nicotinic receptors.
Definition (CSP) slowly hydrolyzed cholinergic agonist that acts at both muscarinic and nicotinic receptors.

Definition (MSH) Agents causing contraction of the pupil of the eye. Some sources use the term miotics only for the parasympathomimetics but any drug used to induce miosis is included here.

Ontology: Parasympathomimetic Agents (C0030512)

Definition (MSH) Drugs that mimic the effects of parasympathetic nervous system activity. Included here are drugs that directly stimulate muscarinic receptors and drugs that potentiate cholinergic activity, usually by slowing the breakdown of acetylcholine (CHOLINESTERASE INHIBITORS). Drugs that stimulate both sympathetic and parasympathetic postganglionic neurons (GANGLIONIC STIMULANTS) are not included here.
