Smooth muscle relaxants work directly on the smooth muscle in the wall of the gut. Taking a medicine that blocks these receptors may cause a dry mouth. For example, muscarinic receptors also help to control the production of saliva in the mouth. Reducing the muscle contractions in this way often helps to relieve some of the symptoms caused by IBS.īecause muscarinic receptors are also found in other parts of the body, taking an antimuscarinic can have other effects. However, in conditions such as irritable bowel syndrome (IBS) these muscle contractions can occur too often or be painful, causing symptoms such as pain and bloating.Īntimuscarinics work by attaching to the receptors and in this way stopping the chemicals from 'docking' there to make the muscle contract. These muscle contractions are brought about by various chemicals produced by your body which stick to special 'docking' sites (receptors) on the muscles. The movement of food along your gut (intestines) happens because some of the muscles in the gut tense (contract) and then relax in a regular pattern throughout the length of the gut.
