Blood Pressure Reduction and Changes in Antihypertensive Medication Use Among Patients With Hypertension Who Initiated Sodium-Glucose Cotransporter-2 Inhibitors.

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have demonstrated a blood pressure (BP) reduction benefit despite other indications for use. We evaluated BP changes and antihypertensive medication use pre- and post-SGLT2i initiation among 12 960 patients with treated hypertension and among subgroups with apparent treatment-resistant hypertension (aTRH) and/or proteinuria. Post-SGLT2i initiation, the mean (SD) systolic blood pressure (SBP) was reduced from 133.9 (16.4) to 128.6 (15.5) mmHg and the mean diastolic blood pressure (DBP) was reduced from 70.8 (11.8) to 68.3 (11.3) mmHg among all patients. The mean SBP/DBP reduction was 5.3/2.5, 6.2/2.8, and 6.1/2.9 mmHg among all patients, patients with aTRH, and patients with proteinuria, respectively. Achieved BP < 130/80 mmHg increased by 12.5%, 16.9%, and 11.1% for all patients, patients with aTRH, and patients with proteinuria, respectively. Discontinuation of ≥ 1 antihypertensive medication within 12 months of SGLT2i initiation occurred in 33.4% overall, 47.6% of patients with aTRH, and 38.7% of patients with proteinuria.
