SGLT2 inhibitors and risk of diabetic ketoacidosis (Q18-11)
What is the issue?
- SGLT2 inhibitors and DPP-4 inhibitors are newer classes of antidiabetic drugs used as second- or third-line treatments in the management of type 2 diabetes.
- However, several safety concerns related with the use of SGLT2 inhibitors have been raised including a potentially increased risk of DKA.
What was the aim of the study?
- This study, evaluated the risk of DKA associated with the use of SGLT2 inhibitors compared to the use of DPP-4 inhibitors.
How was the study conducted?
- CNODES investigators conducted eight population-based cohort studies with electronic health records of over 400,000 patients with type 2 diabetes from seven Canadian provinces and the United Kingdom.
- Cohorts included patients aged 18 years and older who received a prescription for an SGLT2 inhibitor or a DPP-4 inhibitor between 2013 and 2018.
- The risk of DKA was compared in users of SGLT2 inhibitors versus users of DDP-4 inhibitors. Results were combined across studies using a statistical approach called meta-analysis.
What did the study find?
- The use of SGLT2 inhibitors was associated with an almost three-fold relative increase in the risk of DKA compared with DPP-4 inhibitors. This increased risk was observed for each of the three SGLT2 inhibitor molecules (canagliflozin, dapagliflozin, empagliflozin) available during the study period.
- Given the rapidly increasing use of SGLT2 inhibitors in patients with type 2 diabetes, physicians should be aware of DKA as a potential adverse effect.
- CNODES has the ability to analyze a large amount of anonymous patient data to reliably assess questions of drug safety and effectiveness. The results of this study are an important addition to previous research.
- These findings provide evidence of an increased risk of DKA with SGLT2 inhibitors in a real-world setting.
- Physicians should be aware of DKA as a potential adverse effect when prescribing SGLT2 inhibitors.
- Sodium-glucose cotransporter 2 (SGLT2) inhibitor use was associated with an increased risk of diabetic ketoacidosis (DKA) compared to dipeptidyl peptidase-4 (DPP-4) inhibitors among patients with type 2 diabetes.
