🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine works by competitively blocking acetylcholine at muscarinic receptors located on the sphincter muscle of the iris and the ciliary muscle of the lens. This blockade prevents the muscle contraction that normally constricts the pupil and allows the lens to focus on near objects. As a result, the pupil dilates (mydriasis) and the ciliary muscle relaxes (cycloplegia), temporarily paralyzing accommodation. The effects are reversible and last for several hours to a day.
