Pharmacology

Homatropine is a competitive muscarinic receptor antagonist with a bulky aromatic group in place of the acetyl group of acetylcholine. It is expected to act in similar manner as atropine, producing similar parasympatholytic effects. By blocking muscarinic receptors and cholinergic signalling pathways, homatropine blocks the response of the iris sphincter muscle and cause the pupil to become unresponsive to light upon dilation or mydriasis. It also blocks the accommodative muscle of the ciliary body to cholinergic stimulation.

Pregnancy & Lactation

There are no adequate and well-controlled studies in pregnant women. Matropin should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether Homatropine is excreted in human milk. Caution should be exercised when Matropin is administered to a nursing mother.
