Mechanism of action

Docusate sodium is an anionic surfactant that lowers the surface tension of the stool-water interface, allowing water to penetrate and soften the stool mass. Sorbitol is a sugar alcohol that is poorly absorbed in the small intestine, creating an osmotic gradient that draws water into the colon, increasing stool bulk and promoting bowel movement. Together, they provide both softening and osmotic laxative effects for constipation relief.
