🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Homatropine is a competitive antagonist of acetylcholine at muscarinic receptors. By blocking these receptors in the sphincter muscle of the iris and the ciliary muscle, it causes pupil dilation (mydriasis) and paralysis of accommodation (cycloplegia). This action is reversible and shorter-lasting than that of atropine.
