Primary outcomePrimary: Time-weighted Average (TWA) Change From Baseline (0 Hours) to 12 Hours in Heart-Rate-Corrected Augmentation Index (AIx) After A Single Dose of Treatment — -11.1; -0.7; 2.1 percent — p=<0.0005
Summary
This study will test the relationship between CBP (central blood pressure) and PBP (peripheral blood pressure) effects after single and multiple doses of Isosorbide mononitrate extended release (ISMN ER) or Amlodipine besylate in participants with hypertension.
