Clinical implication of SGLT2 inhibitors in type 2 diabetes

다국어 초록 (Multilingual Abstract)

Treatment of type 2 diabetes mellitus (T2DM) continues to present challenges, with many patients failing to achieve glycemic targets. Despite the availability of many oral and injectable anti-diabetic agents, therapeutic efficacy is often offset by undesirable side effects such as hypoglycemia, weight gain and cardiovascular complications. Therefore, the search for new therapeutic agents with an improved benefit-risk profile continues. Recent research has focused on the kidney as a potential therapeutic target, especially because maximal renal glucose reabsorption is increased in T2DM. Under normal physiological conditions, nearly all filtered glucose is reabsorbed in the proximal tubule of the nephron via the sodium/glucose cotransporter 2 (SGLT2). SGLT2-inhibitors are a new class of oral anti-diabetes, which reduce hyperglycemia by increasing urinary glucose excretion independently of insulin secretion or action. Canagliflozin and dapagliflozin in US market, and ipragliflozin and luseogliflozin in Japan market are now available for glycemic control in type 2 diabetics. There are several phase III clinical ongoing trials involving this new class of medications. This review examines some of the key efficacy and safety data from clinical trials of the SGLT2 inhibitors approved, and their future perspectives in the treatment of T2DM.
