Abstract

BACKGROUND
Dapagliflozin is an oral selective inhibitor of sodium-glucose cotransporter 2(SGLT2), the kidney transporter chiefly responsible for glucose reabsorption from the glomerular filtrate. Because this mechanism does not require the action of insulin, dapagliflozin rarely causes hypoglycemia. Dapagliflozin may affect blood glucose control as well as blood pressure and the body weight which are one of the cardiovascular disease risk factors. However, dehydration and ketoacidosis are reported as the side effects of the dapagliflozin treatment and the safety issues have been occurred. The aim of this study is to analyze the effectiveness and adverse events of dapagliflozin in Korean patients.
METHODS
From December 2014 to August 2015, we retrospectively reviewed the electronic medical records of type 2 diabetes patients who were prescribed dapagliflozin at Severance Hospital.
RESULTS
A total of 202 Korean patients were enrolled in this study. The effectiveness in the reduction of blood glucose was statistically significant(p < 0.001). Dapagliflozin decreased 0.74% of HbA1c after 24 weeks. Significantly more participants achieved the target HbA1c level(HbA1c < 7%) after 24 weeks(n=42, 35.3%) than before taking dapagliflozin(n=21, 17.6%). Blood pressure decreased 5.7 mmHg s ystolic b lood p ressure(SBP), 1.9 mmHg d iastolic b lood p ressure(DBP) a fter 24 weeks. M ore than o ne q uarter of participants(n=35, 29.4%) experienced weight loss. Most common adverse event was genitourinary symptoms.
CONCLUSION
In this study, the effectiveness of dapagliflozin in improving glycemic control, blood pressure control, and weight loss was statistically significant. However, elderly and female patients, who have higher incidence of adverse events, should use dapagliflozin cautiously.
