cholinergic-blocking drugs

drugs that block the action of acetylcholine and substances similar to acetylcholine at receptor sites in the synapse

1

mydriasis

dilation of the pupil of the eye caused by contraction of the dilator muscle of the iris

2

parasympathetics

drugs that reduce the activity of the parasympathetic nervous system; also called anticholinergics

3

cholinergic blockers: natural plant alkaloids

atropine [generic], belladonna [Belladonna tincture], hyoscyamine [Levsin], scopolamine [Transderm-Scop]

4

cholinergic blockers: synthetic and semi-synthetic drugs

benztropine [Cogentin], biperidan [Akineton], darifenacin [Enablex], dicyclomine [Bentyl], fesoterodine [Toviaz], glycopyrrolate [Robinul], homatropine [Isopto Homatropine], ipratropium [Atrovent], mepenzolate [Cantil], methscopolamine [Pamine], oxybutynin [Ditropan], procyclidine [Kemadrin], propantheline [Pro-Banthine], solifenacin [Vesicare], tolterodine [Detrol], trihexyphenidyl [generic], trospium [Sanctura]

cholinergic blockers adverse effects: central nervous system

excitation, restlessness, irritability, disorientation, hallucinations, delirium, ataxia, drowsiness, sedation, confusion

7

cholinergic blockers adverse effects: eye

dilated pupils (causing blurred vision), increased intraocular pressure
