Brand: Mydriacyl, Tropicacyl, Opticyl, Visumidriatic
Tropicamide is an anticholinergic medication primarily used to dilate the pupil (mydriasis) and paralyze the ciliary muscle (cycloplegia) for ophthalmic examinations. It belongs to the class of antimuscarinic drugs, which block the action of acetylcholine, a neurotransmitter that controls muscle contraction and glandular secretions. In the eye, this leads to temporary relaxation of the muscles controlling the pupil and lens, facilitating procedures like fundus examination and refraction.
Used to dilate the pupil for ophthalmic examinations.
Outcome:
Increased anticholinergic effects (e.g., dry mouth, blurred vision, constipation)
Mechanism:
Additive anticholinergic activity
Outcome:
Increased risk of systemic anticholinergic effects
Mechanism:
Reduced hepatic clearance of tropicamide
Outcome:
Potentially increased intraocular pressure
Mechanism:
Unknown
Most likely new formulation: sustained-release tropicamide for extended mydriasis (Year: 2026, 30% confidence)
Based on historical safety data and usage patterns, the likelihood of regulatory changes in the next 5 years is low (<5%).
