Homatropine
Homatropine (Equipin, Isopto Homatropine) is an anticholinergic medication that is an antagonist at muscarinic acetylcholine receptors and thus the parasympathetic nervous system. It is used in eye drops as a cycloplegic (to temporarily paralyze accommodation), and as a mydriatic (to dilate the pupil). For Homatropine methylbromide see Methylhomatropine, this is a different medication. Homatropine is less potent than atropine and has a shorter duration of action. It is available as the hydrobromide salt.
