Sorbitol is a sugar alcohol used as an osmotic laxative for the treatment of constipation and for bowel cleansing prior to medical procedures. It is also used in oral care products and as a sweetener in foods. Sorbitol is approved for use as a laxative in several countries.
Pharmacokinetics
Pharmacokinetic parameters for sorbitol are not well characterized in the literature due to its primary local action in the gut and minimal systemic absorption. Estimates below are provided based on typical osmotic laxative pharmacokinetics in healthy adults.
