What Is Domperidone?
Domperidone belongs to a class of medicines called dopamine antagonists.
It works by blocking dopamine receptors in the brain and stomach.
This action reduces the feeling of nausea and improves the movement of food in the stomach and intestines.
Unlike other similar medicines, Domperidone has minimal effect on the brain, which makes it safer for most adults.
How Does Domperidone Work?
Domperidone increases the movement of the stomach and intestines. It enhances muscle contractions in the digestive tract, helping food move forward smoothly.
It also prevents vomiting by blocking dopamine signals that trigger nausea.This dual action makes it useful for treating both nausea and digestive discomfort.
