Docusate is best described as which type of laxative?

• A. Osmotic laxative
• B. Bulk-forming laxative
• C. Stool softener
• D. Stimulant laxative

Answer: (C)

Docusate is a stool softener. It works as a surfactant, lowering the surface tension of the stool so water and fats can mix in, which softens the stool and makes it easier to pass without significantly increasing intestinal movements. This is why it’s often used to prevent constipation and reduce straining, especially when patients should avoid bearing down after surgery or a cardiac event. The effect usually appears in about 1 to 3 days. It isn’t an osmotic laxative, which draws water into the colon to soften and flush stool; it isn’t a bulk-forming laxative, which adds indigestible fiber and increases stool bulk to stimulate movement; and it isn’t a stimulant laxative, which directly increases peristalsis.
