Docusate is an anionic surfactant, which works by reducing the surface tension of the stool, allowing more intestinal water and fat to combine with the stool. This decreases the strain and discomfort associated with constipation.It does not stay in the gastrointestinal tract, but is absorbed into the bloodstream and excreted via the gallbladder after undergoing extensive metabolism.
