Relationship between acute pancreatitis and ACE inhibitors

Most of the acute pancreatitis cases are due to cholelithiasis and alcohol intake.Two percent of the cases are related to medications. Drugs including ACE (angiotensin-converting enzyme) inhibitors and thiazide diuretics may cause acute pancreatitis. Patients with biliary system disorders using certain drugs may develop acute pancreatitis and this may be confusing when considering the aetiology. We report a patient without any known risk factor who developed acute pancreatitis shortly after the intake of lisinopril and hydrochlorothiazide. Common bile duct stone and biliary sludge were diagnosed after physical and radiological evaluation.
