Mydrate

Mydrate Uses, Dosage, Side Effects, Mechanism of Action, How Long Does it Take to Work? Mydrate is a brand name. Its generic name is Cyclopentolate.

Introduction

Mydrate 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

Mydrate 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

Mydrate 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. Mydrate is often combined with epinephrine to produce an even stronger mydriatic and cycloplegic effect.

How Long does it Take to Work?

Mydrate 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

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

Route of Elimination

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

Dosage

The dosage of Mydrate 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

Mydrate 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. Squeeze two drops of the solution into the affected eye, being careful not to touch the eyelids with the dropper. Close the eyelid gently for 1 to 2 minutes and repeat in the other eye, if necessary.

Side Effects

Possible side effects from Mydrate 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.

Precaution

Use caution when administering cyclopentolate to patients with high risk of angle closure glaucoma, patients with cardiovascular disease, or those with severe glaucoma. Patients should avoid driving, operating machinery, and other activities requiring clear vision during treatment with cyclopentolate. Use of contact lenses should be avoided during treatment. It is also important to inform the patient that the effects of cyclopentolate can take several days to wear off.
