Indications

Homatropine eye drops are indicated for use as a mydriatic and cycloplegic agent.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Homatropine works by blocking muscarinic receptors, the same target atropine acts on, so it produces similar effects on the eye. In place of the acetyl group found in acetylcholine, the drug carries a bulky aromatic group, and this structural difference lets it compete with acetylcholine for those receptor sites. Once bound, it interrupts cholinergic signalling in two ways: it stops the iris sphincter muscle from responding, so the pupil widens (dilates) and no longer reacts to light, and it also blocks the ciliary body's accommodative muscle from responding to cholinergic stimulation, limiting the eye's ability to focus.

Pregnancy & Breastfeeding

Nobody has run adequate, well-controlled studies of Matropin in pregnant women. So it should be used during pregnancy only if the likely benefit justifies the possible risk to the baby.

It isn't known whether Homatropine passes into human breast milk. Take care when Matropin is given to a woman who is breastfeeding.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
