Sodium-glucose cotransporter-2 inhibitors (SGLT2i) and glucagon-Like peptide-1 receptor agonists (GLP-1 RA) are recommended in people with type 2 diabetes (T2D) for glycaemic control and for people with high cardiovascular risk. However, current guidelines do not specifically address the role of initial early combination therapy with SGLT2i and GLP-1 RA or dual gastric inhibitory polypeptide (GIP)/GLP-1 RA, but rather sequential initiation with either in T2D. This review synthesizes the available evidence on the use of SGLT2i and GLP-1-based therapies for T2D and provides a rationale for their combination. The combination of SGLT2i with GLP-1-based therapies addresses complementary pathophysiological mechanisms and enhances efficacy in achieving target haemoglobin A1C (HbA1c) levels. SGLT2i and GLP-1 RA also have been shown to prevent complications of T2D. While both classes reduce adverse cardiorenal events, SGLT2i has a predominant effect on prevention of kidney dysfunction and heart failure, whereas GLP-1 RA has a more marked effect on the risk of atherosclerotic cardiovascular disease. Both drug classes have favourable safety profiles. Finally, weight loss with combination therapy may have disease-modifying effects that may reverse T2D progression. We propose that the combination of SGLT2i with GLP-1 RA or dual GIP/GLP-1 RA should be considered for most patients with T2D who do not have contraindications.
