Objective: Sodium-glucose cotransporter-2 inhibitor (SGLT2i) treatment had the effect of reducing blood pressure (BP) and cardiovascular events in recent mega-scale trials, but the effects on BP circadian rhythm remained unclear. The present study aimed to determine the nocturnal antihypertensive effect of SGLT2i compared with dipeptidyl peptidase-4 inhibitor (DPP-4i) in patients with type 2 diabetes and hypertension. Research Design and Methods: In this randomized, open-label, parallel-group trial, patients treated with DPP-4i were either switched to luseogliflozin 2.5 mg/day (Luseo group; n=30) or continued DPP-4i (DPP-4i group; n=26). The patients undertook 24-h ambulatory BP monitoring before and 8 weeks after the group allocation. The primary endpoint was mean change in nighttime systolic BP (SBP). Results: Changes in both nighttime and daytime SBP were significantly reduced in the Luseo group compared with the DPP-4i group (nighttime, −4.0±11.4 vs. 3.6±10.7 mmHg, P=0.01; daytime, −4.4±10.9 vs. 3.7±11.9 mmHg, P=0.01). Similarly, nighttime pulse rate (PR) was significantly reduced in the Luseo group compared with the DPP-4i group (−2.0±4.8 vs. 0.9±4.8 bpm, P=0.03). Abnormal BP circadian rhythms (non-dipper and riser types) were significantly decreased in the Luseo group (56.7% to 36.6%, P<0.05). Conclusions: Switching from DPP-4i to luseogliflozin decreased not only daytime but also nighttime SBP and PR, and improved BP circadian rhythm. These improvements could be some of the factors involved in the cardiovascular event suppression observed with SGLT2i therapy. Disclosure R. Hashimoto-kameda: None. K. Cho: None. H. Nomoto: None. A.
