Drug-induced pancreatitis

Abstract

We reviewed the English-language literature pertaining to drug-induced pancreatitis and attempted to determine whether the reported association between each drug and pancreatitis was valid. The following drugs seem to cause pancreatitis: azathioprine, chlorothiazide and hydrochlorothiazide, oestrogens, frusemide, 6-mercaptopurine, methyldopa, sulphonamides, sulindac, tetracycline and valproic acid. Less convincing but suggestive evidence exists for colaspase, chlorthalidone, combination cancer chemotherapy, cimetidine, cisplatin, corticosteroids, cytosine arabinoside, diphenoxylate, ethacrynic acid, iatrogenic hypercalcaemia, methandienone, metronidazole, nitrofurantoin, pentamidine, phenformin, piroxicam and procainamide. In general, pancreatitis is a very rare complication of treatment with these drugs. The pathogenesis of the pancreatitis is usually obscure, but is probably mediated by an immune response. Certain drugs such as oestrogens cause hypertriglyceridaemia, which in turn may lead to pancreatitis.
