93 publications concerning drug-induced pancreatitis are reviewed. A confirmed causal relationship between drug and acute pancreatitis so far exists only for 8 compounds: azathioprine, chlorothiazide, furosemide, sulfonamides, tetracycline, estrogens, valproic acid and L-asparaginase. There is less convincing, but still suggestive, evidence for a causal relationship with 5 other drugs, namely: corticosteroids, chlorthalidone, ethacrynic acid, phenformin and iatrogenic hypercalcemia. Due to inadequate or contradictory evidence, the link between a number of additional drugs and acute pancreatitis is considered possible, conditional or doubtful. Finally, the scant literature concerning the pathogenesis and histological lesions of drug-induced pancreatitis is briefly reviewed.
