Uses

Main

  • Domperidone is used to move food faster through the food pipe, esophagus, stomach and the intestines. This means the food cannot stay in the same place for too long, thus, reducing the feeling of being full, even before the food is over on the plate.
  • The drug is a dopamine agonist and belongs to the group of drugs called the anti-emetics. The drug helps one overcome the feelings of nausea (feeling sick) and vomiting (being sick).
  • Domperidone is prescribed to people with gastroparesis, a condition where the emptying of the stomach is delayed, when there is no mechanical gastric outlet obstruction. This causes nausea, vomiting, fullness after eating, abdominal pain, bloating, etc. Such patients are given Domperidone to increase the rate of gastric emptying to reduce the symptoms.
  • Parkinson’s disease can cause poor gastrointestinal function, nausea and vomiting in the patient. These symptoms appear as a side effect of the drugs they are given. Domperidone helps these patients get relief from these symptoms by blocking dopamine receptors. This does not worsen the symptoms of Parkinson’s as the drug does not cross the blood-brain barrier.
  • Adults and children with functional dyspepsia are also prescribed Domperidone.

Other

Prolactin helps in the stimulation of lactation and lack of it puts an end to the production of breast milk. Domperidone, however, not used in the US for this or any other use. This is because there is a lack of evidence related to the effects and safety of the drug on the infant.
