How does Metoclopramide work?
Metoclopramide mainly works as a dopamine antagonist (blocks dopamine). Dopamine is a chemical made by your brain that affects many parts of your body, including the digestive tract.
Dopamine normally slows down muscle movements in your gut, causing food to stay in your stomach longer. This can lead to nausea, vomiting, and heartburn. By blocking dopamine, Metoclopramide helps speed up muscle movements in your gut and relieve these stomach-related symptoms. Metoclopramide also tightens a muscle in your gut to stop the backflow of stomach acid into your throat. This helps prevent heartburn.
How do I take Metoclopramide?
Metoclopramide is typically dosed at 10 mg to 15 mg by mouth 4 times daily. It should be taken 30 minutes before meals and at bedtime. Your dose might be lower if you are older than 65 years old, have liver or kidney conditions, or are taking medications that interact with Metoclopramide.
