Source-derived summary

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).

The related chemical compound homatropine methylbromide (methylhomatropine) is a different medication. Homatropine is less potent than atropine and has a shorter duration of action. It is available as the hydrobromide salt. Homatropine is also given as an atropine substitute, given to reverse the muscarinic and CNS effects associated with indirect cholinomimetic (anti-AChase) administration.

Homatropine hydrobromide is on the World Health Organization's List of Essential Medicines.

It is an antagonist of all five muscarinic acetylcholine receptors.

Editorial reviewA dependable orientation record for establishing vocabulary, names and a first evidence trail.

Its strongest next move is a source search built around Homatropine, group and stereoisomers.
Editorial analysis

Why this record matters

“Homatropine” is worth following because a concise public description often conceals a longer documentary argument. Here, Homatropine, group and stereoisomers provides the most credible route into that argument.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jan 2, 2026. The linked authority identifier is Q1038115. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
