Usually available in ophthalmic formulations, tropicamide is used to cause mydriasis and cycloplegia for eye exams or ocular procedures. It is also used in combination with [hydroxyamphetamine] for the same indication. Oral tropicamide has been investigated as a potential drug to relieve sialorrhea in patients with Parkinson's Disease."}]
