Introduction

cyclopentolate is a synthetic anticholinergic drug. It is an acetylcholine receptor antagonist primarily used to decrease intraocular pressure in the diagnosis and treatment of certain kinds of plateau iris, pupillary dilation, anterior and posterior synechiae as well as treatment of esotropia. It is also prescribed for angle closure glaucoma.

Uses

cyclopentolate is used to treat a wide range of ophthalmologic conditions including, but not limited to, intraocular pressure, pupillary dilation, anterior and posterior synechiae, esotropia, and angle closure glaucoma.

Mechanism of Action

cyclopentolate works at acetylcholine receptors and acts as an antagonistic drug against acetylcholine. Its blocking action at cholinergic receptors prevents contraction of radial, circular, and longitudinal muscles, resulting in mydriasis (pupillary dilation), cycloplegia (paralysis of the muscles controlling accommodation for near vision), and decreased intraocular pressure. cyclopentolate is often combined with epinephrine to produce an even stronger mydriatic and cycloplegic effect.

How Long does it Take to Work?

cyclopentolate takes approximately 5-10 minutes to produce its maximal effects. However, its duration of action can last anywhere from days to weeks depending on the dosage and individual.

Absorption

cyclopentolate is rapidly and completely absorbed following topical application to the eyes and systemic absorption is minimal.

Route of Elimination

cyclopentolate is rapidly metabolized to inactive metabolites and is eliminated mainly through urine.

Dosage

The dosage of cyclopentolate depends upon the condition being treated and the particular patient’s response to treatment. The recommended dosage is 1 to 2 drops of she 0.5% ophthalmic solution in each affected eye, 1 to 3 times daily.

Administration

cyclopentolate must be administered accurately and carefully. Wash hands and apply a clean strip of gauze to the lower eyelid. Remain in a seated position and look up slightly.

Close the eyelid gently for 1 to 2 minutes and repeat in the other eye, if necessary.

Side Effects

Possible side effects from cyclopentolate include stinging, burning, itching, blurred vision, temporary increase in intraocular pressure, photophobia, discomfort, nausea, dry mouth, dizziness, confusion, agitation, irritability, and confusion.

Toxicity

Topical application of cyclopentolate may result in mild to moderate systemic toxicity, although serious toxicity from systemic absorption is considered rare. Symptoms of systemic toxicity include nausea, vomiting, rash, headache, delirium, hemolysis, amblyopia, tachycardia, and hypertension.
