Biliary colic: Difference between revisions

Analgesia during the attacks is important. The first choice is [[NSAID|NSAIDs]] like ketorolac, diclofenac, or ibuprofen, and the second choice is [[Opioid|opioids]] like morphine. Many are reluctant to use morphine as it theoretically contricts the sphincter of Oddi, and alternative opioids which cause less constriction (like buprenorphine or meperidine) are often used instead. However, systematic reviews have found that all opioids cause sphincter constriction, and there is no evidence that morphine is worse than other opioids in this regard.
