Some medications are commonly associated with pancreatitis, most commonly corticosteroids such as prednisolone, but also including the HIV drugs didanosine and pentamidine, diuretics, the anticonvulsant valproic acid, the chemotherapeutic agents L-asparaginase and azathioprine, estrogen by way of increased blood triglycerides,[13] and antihyperglycemic agents like metformin,[14] vildagliptin,[15] and sitagliptin.[16] It may be noted here that the drugs used to treat conditions that are themselves associated with increased events of pancreatitis may also be incidentally linked to pancreatitis. Examples include statins in dyslipidemia and gliptins in diabetes. According to the Food and Drug Administration's MedWatch Surveillance System and Published Reports Atypical, atypical antipsychotics such as clozapine, risperidone, and olanzapine can also be responsible for causing pancreatitis.[17]
