osmotic laxative

An osmotic laxative is a medication that helps relieve constipation by drawing water into the intestines. This increased water softens the stool and stimulates bowel movements, making it easier to pass. Osmotic laxatives work by either containing substances that attract water, such as magnesium or phosphate salts, or by holding onto water within the intestinal tract. They typically produce a bowel movement within hours to days, depending on the specific type. These laxatives are often used for short-term relief or to clean out the bowel before medical procedures.
