🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Cyclopentolate is a competitive antagonist at muscarinic acetylcholine receptors. By blocking these receptors in the iris sphincter muscle and ciliary muscle, it prevents acetylcholine from binding, leading to relaxation of the sphincter and paralysis of the ciliary muscle. This results in pupil dilation (mydriasis) and loss of accommodation (cycloplegia).
