Tropicamide is a drug that dilates the pupil and aids in eye examinations. It is offered under the trade names Mydriacyl and others. It is specifically used to aid in the examination of the back of the eye. It's used as an eye drop. The effects start to show after 40 minutes and might last up to a day.
Blurred vision, increased intraocular pressure, and light sensitivity are all common side effects. Psychosis is a rare but serious adverse effect, especially in youngsters. It's uncertain whether using it while pregnant is safe for the baby. Tropicamide belongs to the antimuscarinic group of anticholinergic medicines. It operates by preventing the eye muscles from responding to nerve signals.
In the United States, Tropicamide was licensed for medicinal use in 1960. It is listed as an essential medicine by the World Health Organization.
Tropicamide is an antimuscarinic medication that causes mydriasis (pupil dilatation) and cycloplegia when used as eye drops. It's utilized to examine the lens, vitreous fluid, and retina more thoroughly. It is commonly used during eye tests such as the dilated fundus examination, but it may also be used before or after eye surgery due to its relatively brief duration of impact (4–8 hours). In addition to treating anterior uveitis, cycloplegic drops are frequently used to reduce the risk of posterior synechiae and inflammation in the anterior chamber of the eye.
Tropicamide is sometimes used in conjunction with the sympathomimetic p-hydroxyamphetamine (brand name Paremyd). The iris dilator muscle is directly stimulated by the sympathomimetic medication, resulting in greater dilation. The sympathomimetic drop most usually used in conjunction with tropicamide in the United States is 2.5 percent phenylephrine hydrochloride (brand name AK-Dilate).
Tropicamide causes stinging and a modest, transitory increase in intraocular pressure in the vast majority of people. For a brief time after instillation, it may induce redness or conjunctivitis (inflammation) as well as a blurring of near vision (care must be taken, and the patient must only drive when vision returns to normal). Tropicamide can induce acute angle-closure glaucoma in extremely uncommon cases. This is more common in patients with narrow anterior chamber angles, and the practitioner must estimate the risk of closure prior to instillation.
Tropicamide is frequently used instead of atropine since atropine has a longer half-life, resulting in persistent dilatation and hazy vision for up to a week. Atropine has a milder sting, but if consumed in large amounts by children or adults, it can be poisonous or fatal.
Because of the poor absorption of eye drops into the bloodstream, systemic effects are minor to non-existent.
How does Tropicamide work?
Tropicamide is an anticholinergic medication that causes mydriasis and cycloplegia by nonselectively inhibiting muscarinic receptors. It dilates the pupil by relaxing the pupillary sphincter. The start of tropicamide-induced mydriasis takes about 10 to 15 minutes, with the best effect occurring 25 to 30 minutes after the drug is given. Tropicamide-induced mydriasis lasts four to eight hours, but it can last up to 24 hours in certain people. Tropicamide prevents accommodation by causing the ciliary muscle to contract. The cycloplegic impact occurs within 20 to 30 minutes of treatment, with a four to ten-hour duration of action. Tropicamide has the ability to raise intraocular pressure. The use of tropicamide in the eyes is not usually associated with substantial systemic side effects.
