Valproic acid-associated pancreatitis: report of three cases and a brief review.
We describe three patients with seizure disorders in whom pancreatitis or pancreatic injury was probably caused by valproic acid, a widely used anticonvulsant drug. Trivial or no increases of serum amylase (EC 3.2.1.1) but striking increases of serum lipase (EC 3.1.1.3) were common to all patients, as assayed in the Kodak Ektachem. In vitro, valproic acid does not cause any change in serum lipase. In patients with symptoms suggestive of pancreatitis and abnormal values for amylase and (or) lipase, treatment with valproic acid should be discontinued.
