What type of laxative is NOT intended for long-term use due to the risk of dependence?

Irritants and stimulants are classified as laxatives that increase the motility of the intestines and encourage bowel movements. They work by directly stimulating the nerve endings in the intestinal mucosa or by irritating the intestines, leading to increased peristalsis. While they can be effective for short-term relief of constipation, their use is not recommended for prolonged periods due to the potential for dependence and the risk of causing damage to the intestinal lining. Long-term use can lead to a condition known as "cathartic colon," where the bowels become weakened and less able to function on their own without stimulation.

In contrast, bulking agents, stool softeners, and osmotic agents are generally considered safer for longer-term use as they work by different mechanisms. Bulking agents increase the bulk of stool, making it easier to pass, while stool softeners work by allowing water to mix with the stool, making it softer. Osmotic agents draw water into the intestines to facilitate bowel movements, which does not typically lead to dependence. These alternatives can often be used on a more consistent basis without the same risks associated with stimulant laxatives.
