Case ReportsA new source of drug-induced acute pancreatitis: codeine.
A variety of drugs have been reported to cause acute pancreatitis during the past 40 years. We report the first series of four cases of acute pancreatitis related to codeine ingestion. Four patients (three female, mean age 50.2 yr) presented with clinical, biochemical, and radiological evidence of acute pancreatitis. ⋯ The likely underlying pathophysiological mechanism is codeine-induced spasm of the sphincter of Oddi combined with sphincter of Oddi dysfunction related to a previous cholecystectomy. Codeine ingestion leads to acute pancreatitis in some individuals. Previous cholecystectomy seems to predispose to codeine-induced pancreatitis.
