What type of laxative is used to promote bowel movements?

The correct choice is cathartics because they are specifically designed to stimulate bowel movements and facilitate the expulsion of stool from the intestines. Cathartics work by increasing the motility of the gastrointestinal tract, leading to a quicker and more efficient passage of feces. They can draw water into the intestines or stimulate the muscles of the gut, making them effective for treating constipation or preparing for medical procedures.

In contrast, carminatives are substances that help to relieve gas and bloating by soothing the digestive tract. Antiemetics are used to prevent or treat nausea and vomiting, focusing on stabilizing the stomach rather than promoting bowel movements. Sympathomimetics are agents that mimic the effects of the sympathetic nervous system and have various functions, such as increasing heart rate, but they do not specifically promote bowel movements. Understanding the distinct roles of these compounds highlights why cathartics are the appropriate choice for promoting bowel activity.
