Cyclopentolate, Atropine, Tropicamide, and Homatropine are the typical cycloplegic eye drops used once daily to treat spasm of accommodation by relaxing the ciliary muscle. One side effect is blurred vision since these induce dilation.
Topical atropine is used as a cycloplegic, to temporarily paralyze the accommodation reflex, and as a mydriatic, to dilate the pupils. [15] Atropine degrades slowly, typically wearing off in 7 to 14 days, so it is generally used as a therapeutic mydriatic, whereas tropicamide (a shorter-acting cholinergic antagonist) or phenylephrine (an α-adrenergic agonist) is preferred as an aid to ...
It is commonly used as an eye drop during pediatric eye examinations to dilate the eye and prevent the eye from focusing/accommodating (cycloplegic). Cyclopentolate [citation needed] or atropine can also be administered to reverse muscarinic and central nervous system effects of indirect cholinomimetic (anti-AChase) administration.
Diphenoxylate/atropine, also known as co-phenotrope and sold under the brand name Lomotil among others, is used to treat diarrhea. [ 2 ] [ 3 ] It is a fixed-dose combination of the medications diphenoxylate , as the hydrochloride, an antidiarrheal ; and atropine , as the sulfate, an anticholinergic . [ 1 ]
The effects of atropine on the central nervous system include memory disruption, which may lead to severe confusion. [74] The major effects of belladonna consumption last for three to four hours; visual hallucinations can last for three to four days, and some negative aftereffects are preserved for several days.
However, scopolamine has greater effects on the central nervous system (CNS) than atropine due to its ability to cross the blood–brain barrier. [4] At higher-than-therapeutic doses, atropine and scopolamine cause CNS depression characterized by amnesia, fatigue, and reduction in rapid eye movement sleep.
Parasympathetic fibers travel with cranial nerve III, the oculomotor nerve, to innervate the circular layer of muscle of the eye (sphincter pupillae). Damage to this nerve typically manifests itself as mydriasis, because the sympathetic supply to the pupil, which causes mydriasis, remains unaffected, and therefore unopposed.
