🔬 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 eye. This blockade prevents the muscles from contracting, resulting in pupil dilation (mydriasis) and paralysis of accommodation (cycloplegia). The effects are reversible and temporary.
