Mechanism of Action

Domperidone is a dopamine antagonist (blocking both D1 and D2 receptors) Dopamine antagonism stimulates gastric emptying, increased rate of intestinal transit time and enhanced strength of oesophageal sphincter contractions. The antiemetic effect of domperidone is due to the prokinetic effect on the gastrointestinal tract combined with antagonisation of dopamine receptors in the chemo trigger zone (CTZ). Domperidone does not readily cross the blood brain barrier.

Warnings and precautions

Before taking this medicine contact your doctor if you:

• suffer from liver problems (liver function impairment or failure)

• suffer from kidney problems (kidney function impairment or failure). It is advisable to ask your doctor for advice in case of prolonged treatment as you may need to take a lower dose or take this medicine less often, and your doctor may want to examine you regularly.

Domperidone may be associated with an increased risk of heart rhythm disorder and cardiac arrest. This risk may be more likely in those over 60 years old or taking doses higher than 30mg per day. The risk also increases when domperidone is given together with some drugs.

Tell your doctor or pharmacist if you are taking drugs to treat infection (fungal infections or bacterial infection) and/or if you have heart problems or AIDS/HIV. 

Domperidone should be used at the lowest effective dose. While taking domperidone, contact your doctor if you experience heart rhythm disorders such as palpitations, trouble breathing, and loss of consciousness. Treatment with domperidone should be stopped.
