Docusate sodium solution is an anionic surfactant widely used as a stool softener in medical settings to relieve constipation. It works by facilitating the penetration of water and lipids into the stool, increasing its water content and making it easier to pass. This solution is often prescribed for patients who should avoid straining during bowel movements, such as those recovering from surgery, experiencing hemorrhoids, or dealing with heart conditions. It is also used in veterinary medicine to treat constipation in animals. Additionally, it can be found in over-the-counter laxative products for general use and in bowel preparation regimens before medical procedures. In pharmaceutical and cosmetic formulations, it serves as an emulsifier, solubilizer, and wetting agent. Its gentle action makes it suitable for both short-term and long-term use under medical supervision.
