A Double‐blind Randomized Clinical Trial Evaluating the Analgesic Efficacy of Ketorolac versus Butorphanol for Patients with Suspected Biliary Colic in the Emergency Department

Abstract

Although limited by small sample size and convenience sample, this study demonstrates that both ketorolac and butorphanol provide pain relief in biliary colic. Both agents should be considered reasonable options in the ED treatment of biliary colic, especially in patients that may undergo HIDA.
