Colospa acts directly on the smooth muscle in the gut causing it to relax. It also prevents nerve signals getting through to the muscle in the intestines. This also causes the muscle to relax, preventing painful muscle spasm. Little or no antispasmodic effect was seen on the uterus and the bronchial muscles. Gastric emptying time and intestinal propulsion were affected much less than by papaverine. No significant inhibition of normal peristalsis has been observed.
Primary irritable colon characterised by persistent diarrhoea, alternating constipation and diarrhoea, abdominal pain and postprandial distension. Secondary irritable colon due to organic lesions such as regional enteritis, diverticulitis, specific and non-specific inflammatory conditions of the gastro-intestinal tract.
