O que é Hyoscine Butylbromide?
Hyoscine Butylbromide — best known by the brand name Buscopan in many European markets — is an antispasmodic medicamento used to relieve abdominal pain and cramps caused by smooth muscle spasm in the gastrointestinal tract and urinary system. It belongs to the antimuscarinic (anticholinergic) class of medicamentos.
Unlike its close chemical relative Hyoscine Hydrobromide (utilizado para travel sickness and as a pre-operative sedative), Hyoscine Butylbromide is specifically formulated as a quaternary ammonium compound. This structure prevents it from crossing the blood-brain barrier in significant amounts at therapeutic doses, which means it acts locally on the gut without causing the sedation, confusion, or other central nervous system effects associated with other anticholinergics.
Hyoscine Butylbromide is used to relieve the pain and discomfort associated with:
- Irritable Bowel Syndrome (IBS): Abdominal cramping and spasms
- Menstrual cramps (dysmenorrhoea): Uterine smooth muscle spasm
- Gastrointestinal spasm: From conditions such as diverticular disease or acute gastroenteritis
- Biliary and renal colic: Spasm of the bile ducts or urinary tract (typically in a clinical setting)
Como funciona Hyoscine Butylbromide work?
Hyoscine Butylbromide is a competitive antagonist of muscarinic acetylcholine receptors (primarily M1, M2, and M3 subtypes) in smooth muscle tissue of the gut and urinary tract. By blocking these receptors, it prevents acetylcholine from binding and triggering muscle contraction.
The result is relaxation of smooth muscle in:
- The wall of the intestine (reducing gut motility and intestinal cramping)
- The bile ducts and gallbladder
- The ureter and urinary bladder
This selective action on peripheral smooth muscle — without meaningful central nervous system effects at standard doses — makes Hyoscine Butylbromide well suited for ambulatory (outpaciente or home) management of gastrointestinal spasm.
Para quem é Hyoscine Butylbromide for?
Hyoscine Butylbromide is appropriate for adults and adolescents experiencing:
- Recurrent abdominal cramping and pain consistent with IBS
- Acute menstrual pain (dysmenorrhoea) with a cramping component
- Abdominal pain from gastrointestinal spasm in the context of other diagnosed conditions
It should not be used by people with:
- Myasthenia gravis (anticholinergic medicamentos may worsen muscle weakness)
- Urinary retention or risk of urinary retention (e.g., benign prostatic hyperplasia)
- Narrow-angle glaucoma
- Significant obstruction of the gastrointestinal or urinary tract
- Megacolon or paralytic ileus
Hyoscine Butylbromide is also not recommended during pregnancy, particularly the first trimester, without medical guidance. Women who are pregnant or breastfeeding should consult a médico before use.
Dosagem
For adults and adolescents over 12 years, typical guidance based on EMA-approved prescribing information is:
| Formulation | Dose | Frequency |
|---|---|---|
| Oral comprimidos (10 mg) | 10–20 mg | Up to 3–4 times daily |
| Maximum daily dose | 80 mg | Do not exceed |
Tablets should be swallowed whole with water. Dosing should be taken as needed for symptom relief rather than continuously, unless a médico has advised a regular dosing schedule.
Higher-dose formulations or combination products may be available on receita médica.
Efeitos secundários
Because Hyoscine Butylbromide acts primarily peripherally (outside the brain), central nervous system efeito secundários are uncommon at standard oral doses. However, anticholinergic effects in the rest of the body may occur.
Efeitos secundários comuns
- Dry mouth (reduced saliva production)
- Constipation (slowing of gut motility)
- Urinary hesitancy or difficulty urinating
- Blurred vision (reduced accommodation)
- Reduced sweating (which can increase body temperature in hot environments)
Menos comuns efeito secundários
- Increased heart rate (tachycardia)
- Flushing
- Skin rash
Serious but rare efeito secundários
- Acute urinary retention: Particularly in men with pre-existing prostate enlargement
- Acute angle-closure glaucoma: In susceptible individuals (pre-existing narrow-angle glaucoma)
- Serious allergic reactions: Including anaphylaxis (very rare)

Informação de segurança importante
Não utilize Hyoscine Butylbromide if you have:
- Myasthenia gravis
- Narrow-angle glaucoma
- Urinary retention or difficulty urinating
- Significant gastrointestinal obstruction or paralytic ileus
- Megacolon
Seek urgent medical attention if you experience:
- Severe abdominal pain that is new, worsening, or accompanied by fever
- Blood in your stools or black/tarry stools
- Unintended weight loss
- Difficulty swallowing
These symptoms may indicate a serious underlying condition that requires urgent medical investigation, not antispasmodic tratamento.
Important: Hyoscine Butylbromide relieves the symptoms of cramping — it does not treat the underlying cause. If your symptoms are new, severe, or not responding to tratamento, an independent médico should evaluate you.
