Medical action:

Domperidone is a peripheral dopamine (D2) and (D3) receptor antagonist. It provides relief from nausea by blocking receptors at the chemoreceptor trigger zone (a location in the nervous system that registers nausea) at the floor of the fourth ventricle (a location near the brain). It increases motility in the upper gastrointestinal tract to a moderate degree and increases lower esophageal sphincter pressure by blocking dopamine receptors in the gastric antrum and the duodenum. It blocks dopamine receptors in the posterior pituitary gland increasing the release of prolactin which in turn increases lactation. Domperidone may be more useful in some patients and cause harm in others by way of the genetic characteristic of the person, such as polymorphisms in the drug transporter gene ABCB1, the potassium channel KCNH2 gene, and α1D--adrenoceptor ADRA1D gene.

Precautions:

Take special care with this medicine

Check with your doctor or pharmacist before taking these tablets if you:

have any kidney problems. If you take domperidone over a long period, your doctor may want to lower the amount you use. This will depend on how severe your kidney problems are.
