At the intestinal level, different movements are needed to achieve defecation, that is, the expulsion of feces, these movements are known by the name of peristaltic movements which are classified into segmented ones which allow the propulsion of feces through the ascending colon and mass movements this helps the movement of stool through the transverse and sigmoid colon.
It should be noted that these movements are generated thanks to coordination by the parasympathetic nervous system, when there is a variation in the speed of these peristaltic movements, the number of times the patient defecates will be directly affected, if these bowel movements are decreased (or slow) it is then said that the patient has constipation, which translates into difficulty in achieving defecation.
For this type of pathology, the science in charge of health gave fruit to different drugs called laxatives, laxatives focus on facilitating the evacuation of the patient by different methods, this type of drugs are in different presentations can be found in pills, capsules, solution or syrup to be consumed or administered orally. The main mechanism of action of this type of drug is to change the structures of the stool, allowing them to be classified into different groups such as: waste-forming laxatives, which are based on increasing the volume of the stool through the absorption of water by of this organic materialthus achieving increased peristaltic movements by pressure, emollient laxatives or lubricants.
This type of drug is responsible for coating the stool to promote lubrication when passing through the intestinal lumen, hyperosmoral laxatives produce intestinal peristaltic movement by causing the absorption of water in the stool increasing its volume, laxatives can also be mentioned These are made from sodium that also causes water retention by the fecal matter and finally, there are stimulant laxatives, these do not alter the structure of the fecal matter but induce peristaltic movements directly in the intestines, causing stimulation of the nerves that innervate this type of tissue.
