Mannitol oral excretion time varies from person to person, and Mannitol is not recommended to drink often.
Mannitol for monosaccharide, oral absorption is very little, in the original form of intestinal excretion, its excretion fast and slow with the patient’s gastrointestinal function, stool dryness, whether the movement and so on are related, so the excretion time varies from person to person.
Commonly used 20% mannitol for hypertonic solution, oral intake can make the intestinal osmotic pressure rise, prevent intestinal water absorption, so that the intestinal content of the volume increased, the intestinal tract was dilated, thus stimulating the intestinal wall, enhance intestinal peristalsis, so that intestinal contents rapidly discharged.
Mannitol is highly osmotic and is mainly used for diuresis, treatment of cerebral edema, intracranial hypertension, glaucoma, preoperative bowel preparation, etc. It is not used orally except for bowel preparation. Therefore, it is only recommended to be used in preoperative bowel preparation, and mannitol is not recommended as a regular laxative, much less for frequent oral administration.
