Domperidone is a peripherally selective D2 receptor antagonist. It acts as an antiemetic and a prokinetic agent through its effects on the chemoreceptor trigger zone and motor function of the stomach and small intestine. Domperidone was not approved in USA due to risks of cardiac arrhythmias, cardiac arrest, and sudden death, but is available in other countries. However, FDA allows access to Domperidone through an expanded access investigational new drug application (IND) to patients with gastroesophageal reflux disease with upper GI symptoms, gastroparesis, and chronic constipation. As an “off-label” use, domperidone is prescribed to breastfeeding women to enhance their milk production.

Domperidone should be taken 15-30 minutes before meals and, if necessary, before retiring. Adult dose of the drug is 10 mg three times daily. Domperidone is also available as suppository or as a solution for intramuscular injection.
Route of Administration:
Other
After dissection, rat striata were homogenized by seven manual strokes in a Wheaton Teflon-glass homogenizer with ice cold 50 mM HEPES buffer, centrifuged at 27000g, the supernatant was discarded. The pellet was homogenized (five strokes), resuspended in ice cold buffer, and centrifuged again. Nonspecific binding of [3H]Spiperone (ca.0.07 nM) was defined by adding unlabeled chlorpromazine. Binding was terminated by filtering with 15 mL of ice cold buffer. Radioactivity was determined on an LKB-1219 Rack-Beta liquid scintillation counter. Domperidone binds to D2 receptorss with Ki of 1 nM
