DRopEridol for Abdominal pain in the emergency department for Morphine Equivalent Reduction. The DREAMER study.

Introduction: Droperidol is a dopamine-2 receptor antagonist in the class of butyrophenone antipsychotics with antiemetic, sedative, analgesic, and anxiolytic properties. In the postoperative setting, droperidol provides an opioid sparing effect and decreases nausea/vomiting. Another butyrophenone antipsychotic, haloperidol, has been shown to reduce morphine milliequivalents (MME) administered when used for abdominal pain in the emergency department (ED).
