Hyoscine butylbromide
chemical compound
Hyoscine butylbromide, also known as scopolamine butylbromide and sold under the brand name Buscopan among others, is an anticholinergic medication used to treat abdominal pain, esophageal spasms, bladder spasms, biliary colic, and renal colic. It is also used to improve excessive respiratory secretions at the end of life. Hyoscine butylbromide can be taken by mouth, injection into a muscle, or into a vein.
Side effects may include sleepiness, vision changes, dry mouth, rapid heart rate, triggering of glaucoma, and severe allergies. Sleepiness is uncommon. It is unclear if it is safe in pregnancy. It appears safe in breastfeeding. Greater care is recommended in those with heart problems. It is an anticholinergic agent, which does not have much effect on the brain.
Hyoscine butylbromide was patented in 1950, and approved for medical use in 1951.

Why this record matters
The phrase “chemical compound” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jan 1, 2026. The linked authority identifier is Q419361. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1950 and 1951.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
