How does Domperidone work?
Domperidone works mainly by blocking dopamine receptors. This causes an increased contraction of the muscles in the stomach, tightening of the muscles at the entry to the stomach, and relaxation of the muscles at the exit of the stomach itself. These actions accelerate the passage of food through the stomach into the intestine. It helps prevent vomiting and lessens bloating, feelings of sickness, and fullness. It also stops food from flowing the wrong way through the stomach and thus prevents reflux.
This medicine also blocks dopamine receptors establish in the chemoreceptor trigger zone (CTZ). The CTZ is stimulated by nerve messages from the stomach when an irritant is existent. It is also activated openly by agents flowing in the blood. When activated, it sends messages to a different part of the brain that sends messages to the gut that causes the vomiting reflex. Delaying the dopamine receptors in the CTZ stops nausea messages from being directed to the vomiting center. This decreases the feeling of nausea and prevents vomiting.
