4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Mydriatics

Agents that dilate the pupil. They may be either sympathomimetics or parasympatholytics. (See all compounds classified as Mydriatics.)


Muscarinic Antagonists

Drugs that bind to but do not activate MUSCARINIC RECEPTORS, thereby blocking the actions of endogenous ACETYLCHOLINE or exogenous agonists. Muscarinic antagonists have widespread effects including actions on the iris and ciliary muscle of the eye, the heart and blood vessels, secretions of the respiratory tract, GI system, and salivary glands, GI motility, urinary bladder tone, and the central nervous system. (See all compounds classified as Muscarinic Antagonists.)


Parasympatholytics

Agents that inhibit the actions of the parasympathetic nervous system. The major group of drugs used therapeutically for this purpose is the MUSCARINIC ANTAGONISTS. (See all compounds classified as Parasympatholytics.)
