Buscopan vs Mebeverine: Mechanism Of Action And Symptoms Control

Although used in the symptomatic treatment of the same condition, Buscopan and Mebeverine are not the same drugs.

  • Buscopan is a brand name for a drug called Hyoscine Butylbromide. Over the counter, Buscopan is sold as Buscopan Cramps and Buscopan IBS Relief (same drug, different names and availability).
  • Mebeverine, on the other hand, is a generic name of the drug, which is also known as Colofac (brand name).

Both Products Contain The Same Active Ingredients Regardless Of Whether They Are Prescribed Or Purchased Over The Counter:

  • Each Buscopan tablets contains 10mg of Hyoscine Butylbromide.
  • Each Colofac or Mebeverine tablet contains 135mg of Mebeverine Hydrochloride.

Symptoms Control (Mechanism Of Action)

Irritable Bowel Syndrome (IBS) has a range of side effects including:

wome suffering from stomach pain

  • Stomach cramps,
  • Stomach pain,
  • Bloating and
  • Changes in bowel habit including diarrhoea or constipation.

Buscopan works by relieving spasms of the smooth muscle which forms part of the gastrointestinal (GI), biliary and genitourinary tracks. Smooth muscle relaxation ‘counteracts’ some of the symptoms experienced by IBS patients. Hyoscine belongs to a group of drugs called Anticholinergics.

Mebeverine exercises the same effect on the smooth muscle of the GI tract. Mebeverine belongs to a group of drugs called Antispasmodics, which relax the smooth muscle.

Antispasmodics drugs should theoretically improve the symptoms of IBS by reducing muscle contractions and spasm (Chang, 2014).

Although both drugs exhibit the same end effect, at a cellular level, their mechanism of action is different.

The above prescribing data reflect the guidelines on the management of IBS as detailed in the next paragraph.

Ongoing Treatment Of Irritable Bowel Syndrome

Drug treatment can be considered on a trial basis alongside dietary and lifestyle adjustments, such as eating regular, healthy and well-balanced meals. Symptoms of diarrhoea and constipation can be managed with different drugs which are not reviewed in this post.

Healthy diet plays important role in the management of IBS symptoms

Antispasmodic drugs such as Mebeverine can be considered in the management of IBS when ongoing symptoms of abdominal pain or spasm are present.

Mebeverine is the preferred drug of choice over Antimuscarinic drugs such as Hyoscine Butylbromide (Buscopan), as it is less likely to cause side effects (BNF, 2017).

When recommending treatment, NICE looks at existing evidence from clinical trials to support prescribing decision making. Small studies suggest that antispasmodics (Mebeverine) may help with IBS symptoms such as pain and bloating.

Several studies found Hyoscine Butylbromide effective and beneficial in the abdominal pain caused by cramping, making it a valuable treatment of IBS (Tytgat, 2007).

Conclusion

Buscopan (Hyoscine Butylbromide) and Colofac IBS (Mebeverine Hydrochloride) are products which can be purchased over the counter for the management of IBS symptoms. Although both products have a similar effect in controlling IBS symptoms, the active ingredients found in Buscopan and Colofac are different.

In the UK, the guidelines on the management of IBS inclines towards Mebeverine as a first choice in IBS treatment; however, patients may need to trial both drugs to see if control of symptoms is improved. Patients need to remember about the importance of contacting their GP if symptoms are persistent, and the previous diagnosis of the condition was made by a doctor.
