What is Mydriacyl
TropicamideThe Generic name of this drug
Treatment SummaryTropicamide is a type of medication that blocks the action of the chemical acetylcholine, which helps to relax the muscles in the eyes. It is used to dilate the pupils and paralyze the ciliary muscle during eye exams and ocular procedures. It is also used in combination with another drug, hydroxyamphetamine, for the same purpose. Tropicamide has also been studied as a potential treatment for drooling in people with Parkinson's disease when taken orally.

Effectiveness
How Mydriacyl Affects PatientsTropicamide is a drug used to widen the pupils and temporarily paralyze the muscles in the eye. It usually starts to work within 10-15 minutes, and can last up to 24 hours. It can also increase the pressure in the eye, but serious side effects are not normally seen. It has been used in Parkinson's Disease to reduce saliva production, and has also been shown to reduce tremors in rodent models.
How Mydriacyl works in the bodyTropicamide is a drug that blocks the activity of muscarinic receptors, which are found in the eye and salivary glands. In the eyes, these receptors play a role in pupil constriction and near vision. By blocking these receptors, tropicamide causes the pupil to dilate and prevents near vision. It also blocks muscarinic receptors found in salivary glands, which helps reduce excessive saliva production.
