ABSTRACT Introduction: Both sodium-glucose co-transporter-2 inhibitors (SGLT-2Is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) have been consistently found to lower blood glucose, body weight and systolic blood pressure (SBP) in patients with type 2 diabetes mellitus (T2DM). While all the SGLT-2Is inhibit glucose reabsorption by blocking SGLT-2 receptor in kidney, dose-dependently, the highest licensed dose of canagliflozin 300-mg has an additional ability to inhibit SGLT-1 receptor in intestine transiently, that may lead to additional inhibition of prandial glucose absorption, unlike other approved highly selective SGLT-2Is. Areas covered: An electronic search on studies with highest licensed dose of all approved SGLT-2Is and long-acting GLP-1RAs was made up to December 2016. We systemically reviewed the studies of canagliflozin 300-mg and compared its glucose, body weight and SBP lowering with other approved SGLT-2Is and GLP-1RAs in their highest approved doses. Expert commentary: From the available evidences, it appears that canagliflozin 300-mg may have the highest potential to improve gluco-metabolic profile in T2DM, amongst the SGLT-2Is class. While the highest approved dosage of GLP-1RAs lowered HbA1c better than canagliflozin 300-mg, weight and SBP lowering could be non-inferior or slightly better with the latter drug. Nonetheless, only head-to-head trial can conclusively answer these questions.
