Dapagliflozin efficacy and safety: a perspective review.

Type 2 diabetes mellitus is a prevalent, progressive disease with a need for innovative therapeutic agents to continue to advance disease management. Dapagliflozin is the second agent in a new class of oral antihyperglycemic drugs: sodium-glucose cotransporter 2 (SGLT2) inhibitors. SGLT2 is responsible for the majority of renal glucose reuptake; inhibition of the cotransporter allows for increased renal glucose excretion that consequently leads to reduced plasma glucose levels. Because this mechanism does not require the action of insulin, dapagliflozin rarely causes hypoglycemia and is effective in patients both early and late in the course of their disease. Studies of dapagliflozin have demonstrated efficacy both as monotherapy and in combination with oral antihyperglycemic agents and insulin. Dapagliflozin has been shown to decrease hemoglobin A1c (HbA1c) values 6 mmol/mol (0.5%) to 8 mmol/mol (0.7%). The most common adverse reactions observed with dapagliflozin in clinical trials were female genital mycotic infections, urinary tract infections, and nasopharyngitis. Dapagliflozin is a new oral agent for type 2 diabetes with short-term efficacy similar to dipeptidyl peptidase 4 inhibitors; its long-term safety and efficacy are unknown.
