An update on the safety and efficacy of oral antidiabetic drugs: DPP-4 inhibitors and SGLT-2 inhibitors

Abstract

ABSTRACTIntroduction: Oral antidiabetic medications are important in many type 2 diabetes care plansAreas covered: The article summarizes the cardiovascular and renal safety data for DPP-4 inhibitors and SGLT-2 inhibitors and specific safety data particular to each class.Expert opinion: DPP-4 and SGLT-2 inhibitors provide unique anti-hyperglycemic mechanisms. The cardiovascular safety profiles of DPP-4 inhibitors are promising, but do not show the strong CV risk reduction of empagliflozin and canagliflozin. The heart failure signal associated with DPP-4 inhibitor use is unclear with differing agents, demonstrating increased risk or maybe even protective effects. The risk reduction in cardiovascular disease associated with SGLT-2 inhibitors has translated to recommendations to consider these therapies early in the treatment pathway. Both classes have potential safety concerns that necessitate appropriate patient selection and thorough education on potential side-effects. DPP-4 inhibitors are considered to have neutral or in some studies beneficial renoprotective effects. SGLT-2 inhibitor safety effects on the kidney are more complex. There are reports of acute kidney injury occurring soon after initiating SGLT-2 inhibitor therapy. However, there are large recent studies that have demonstrated the beneficial effect of SGLT-2 inhibitors in slowing the progression of established chronic kidney disease.Trial registration: ClinicalTrials.gov identifier: NCT01243424.Trial registration: ClinicalTrials.gov identifier: NCT01897532.Trial registration: ClinicalTrials.gov identifier: NCT02065791.Trial registration: ClinicalTrials.gov identifier: NCT01986881.
