🔬 How This Medicine Works (Pharmacology)

Peak Plasma TimeNot established from the available information.
Duration of ActionMydriasis and cycloplegia typically last 6-24 hours.

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).

Mechanism Steps

1
Receptor binding: Cyclopentolate binds competitively to muscarinic acetylcholine receptors on the iris sphincter and ciliary muscle.
2
Blockade of acetylcholine: It prevents acetylcholine from activating these receptors, leading to inhibition of muscle contraction.
3
Pupil dilation: Relaxation of the iris sphincter causes the pupil to dilate (mydriasis).
4
Cycloplegia: Paralysis of the ciliary muscle results in loss of accommodation, making it difficult to focus on near objects.
