What is Domperidone?

Plain description, key identifiers and synonyms

Domperidone is 1-[3-(Piperidin-1-yl)propyl]-1,3-dihydro-2H-benzimidazol-2-one in which the 4-position of the piperidine ring is substituted by a 5-chloro-1,3-dihydro-2H-benzimidazol-2-on-1-yl group. A dopamine antagonist, it is used as an antiemetic for the short-term treatment of nausea and vomiting, and to control gastrointestinal effects of dopaminergic drugs given in the management of parkinsonism. The free base is used in oral suspensions, while the maleate salt is used in tablet preparations. It has a role as a dopaminergic antagonist and an antiemetic. It is a member of benzimidazoles and a heteroarylpiperidine.

Domperidone is a peripherally selective dopamine D2 receptor antagonist, used as an antiemetic, gastroprokinetic agent, and galactagogue.

Pharmacology

Domperidone is a peripheral-specific antagonist of the dopamine receptor D2 (D2R), with antiemetic, gastrokinetic and galactagogue activities. Following administration, domperidone binds to D2R expressed by peripheral neurons, this inhibits dopamine binding and D2R-mediated signaling. Inhibition of peripheral D2R signaling prevents or relieves various gastrointestinal (GI) symptoms, such as nausea and vomiting, and may help relief reflux and symptoms of a variety of other upper GI disorders.
