Mebeverine is a drug whose major therapeutic role is in the treatment of irritable bowel syndrome (IBS) and the associated abdominal cramping. It works by relaxing the muscles in and around the gut. It is a musculotropic antispasmodic drug without anticholinergic side-effects. The drug is also indicated for treatment of gastrointestinal spasm secondary to organic disorder. It was first registered in 1965 and is marketed as Colofac, Duspatal, Colotal, Colospa, Mebeverine(e-i-a), Rudakol, Boots IBS relieve, Fomac, Mebecon and Duspatalin by Abbott Laboratories.

Indications[edit]

Spastic functional disturbances of the colon:

Mode of action[edit]

Mebeverine is an antimuscarinic. It belongs to a group of compounds called musculotropic antispasmodics. These compounds act directly on the gut muscles at the cellular level to relax them. This relieves painful muscle spasms of the gut, without affecting its normal motility. Mebeverine is used to relieve symptoms of irritable bowel syndrome and related intestinal disorders that are the result of spasms in the intestinal muscles. These include colicky abdominal pain and cramps, diarrhoea alternating with constipation and flatulence (wind).

Mebeverine is also an inhibitor of calcium-depot replenishment. Therefore, it has dual mode of action which normalizes the small bowel motility.

Adverse effects[edit]

Side effects may include:[1]

Since 1978, 21 cases of severe adverse reactions to mebeverine were reported in the Netherlands.[2] Most reactions consisted of urticaria or maculopapular rash, sometimes accompanied by fever, polyarthritis, thrombopenia or angioedema.

Very rarely, people taking this medicine may develop allergic reactions.[3]

Pregnancy and breastfeeding[edit]

Mebeverine passes into breast milk, but the amount is considered too small to be harmful to a nursing infant.

Driving and using machines[edit]

Mebeverine is unlikely to affect your ability to operate machinery or to drive, yet not completely out of the question. [4] [5]
