What is domperidone?

Domperidone is an antiemetic (anti-sickness) and prokinetic drug. It belongs to a group of drugs called dopamine antagonists. It is used to treat stomach-related issues, such as nausea and vomiting, as well as stomach pain and discomfort caused by decreased movement of the stomach and upper gastrointestinal (GI) tract. It is also used to boost breastmilk supply.

Domperidone works by blocking dopamine receptors in the gut. It increases the movement or contractions of the muscles in your stomach and intestines, increasing how quickly and easily food moves through your digestive tract. It also acts on the chemoreceptor trigger zone in your brain, which is involved in nausea and vomiting. This area of your brain is outside the blood-brain barrier. Unlike other dopamine antagonists, domperidone does not cross the blood-brain barrier, which minimizes central nervous system (CNS) side effects.

Domperidone works to boost breastmilk supply by increasing the level of a hormone called prolactin, which stimulates the production of breastmilk.

Domperidone is available on prescription and in some places as an over-the-counter (OTC) medicine. It is available in many places around the world, including the UK, Europe, Canada and New Zealand. Approved uses of the drug vary from country to country. It is also used for off-label or unapproved conditions, including boosting breastmilk supply. Domperidone is not approved for use in the US, but some patients with severe gastrointestinal motility disorders can still access it through an expanded access investigation new drug (IND) application.

Domperidone first became available in the late 1970s.
