Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
