RT Journal Article SR Electronic T1 Domperidone, a new dopamine antagonist JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 457 OP 461 VO 135 IS 5 A1 M. C. Champion A1 M. Hartnett A1 M. Yen YR 1986 UL http://www.cmaj.ca/content/135/5/457.abstract AB Domperidone is a dopamine antagonist that has recently been released in Canada. Unlike metoclopramide hydrochloride, the other available dopamine antagonist, it does not readily enter the central nervous system. Domperidone acts as both an antiemetic and an upper gastrointestinal tract prokinetic agent. It is rapidly absorbed after oral administration, and few side effects have been reported. Domperidone has been approved for use in Canada for the symptomatic management of upper gastrointestinal tract motility disorders and to prevent gastrointestinal symptoms associated with the use of dopamine agonist agents in Parkinson's disease. The pharmacologic features, indications and side effects of domperidone are reviewed.
