Magnesium citrate belongs to a class of medications calledosmotic laxativesandpurgatives. It works by drawing and retaining water into the large colon. This softens the stool and stimulates the rhythmic movement of the muscles in the colon, leading to a bowel movement.
Magnesium citrate is used for the short-term of relief of constipation, and to cleanse the bowels prior to certain procedures, such as a colonoscopy.
