Incretin-based Drugs and Acute Pancreatitis

The purpose of this study is to determine whether incretin-based drugs (used to treat type 2 diabetes) taken either alone or in combination with other anti-diabetic drugs are associated with an increased risk of acute pancreatitis (AP) compared to other combinations of oral hypoglycemic agents (OHA). The investigators will carry out separate population based cohort studies using administrative health databases in six jurisdictions in Canada, the US, and the UK. Cohorts will be defined by the initiation of a new anti-diabetic drug when incretin-based drugs entered the market, with follow-up until hospitalization for AP. The results from the separate sites will be combined to provide an overall assessment of the risk of AP in users of incretin-based drugs and by class of incretin-based drugs.
