Homatropine (Equipin, Isopto Homatropine) is an anticholinergic medication that is an antagonist at muscarinic acetylcholine receptors and thus the parasympathetic nervous system. It is used in eye drops as a cycloplegic (to temporarily paralyze accommodation ), and as a mydriatic (to dilate the pupil ).
A spasm of accommodation (also known as a ciliary spasm, an accommodation, or accommodative spasm) is a condition in which the ciliary muscle of the eye remains in a constant state of contraction. Normal accommodation allows the eye to "accommodate" for near-vision. However, in a state of perpetual contraction, the ciliary muscle cannot relax ...

[ 3] Specifically it is used to help examine the back of the eye. [ 4] It is applied as eye drops. [ 3] Effects occur within 40 minutes and last for up to a day.
Cyclopentolate is a muscarinic antagonist. [ 2] It is commonly used as an eye drop during pediatric eye examinations to dilate the eye ( mydriatic) 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 ...
Recurrent corneal erosion is a disorder of the eyes characterized by the failure of the cornea 's outermost layer of epithelial cells to attach to the underlying basement membrane ( Bowman's layer ). The condition is excruciatingly painful because the loss of these cells results in the exposure of sensitive corneal nerves.
For symptomatic bradycardia, the usual dosage is 0.5 to 1 mg IV push; this may be repeated every 3 to 5 minutes, up to a total dose of 3 mg (maximum 0.04 mg/kg). [ 23 ] Atropine is also useful in treating second-degree heart block Mobitz type 1 (Wenckebach block) , and also third-degree heart block with a high Purkinje or AV-nodal escape rhythm .
Ophthalmic drug administration is the administration of a drug to the eyes, most typically as an eye drop formulation. Topical formulations are used to combat a multitude of diseased states of the eye. These states may include bacterial infections, eye injury, glaucoma, and dry eye. [1] However, there are many challenges associated with topical ...
Eye drop. Eye drops or eyedrops are liquid drops applied directly to the surface of the eye usually in small amounts such as a single drop or a few drops. Eye drops usually contain saline to match the salinity of the eye. Drops containing only saline and sometimes a lubricant are often used as artificial tears to treat dry eyes or simple eye ...
