This study is designed as a mechanistic study to compare the effect of two different combinations of anti-hypertensive treatments (aliskiren and valsartan vs. telmisartan and ramipril) on the renin-angiotensin-aldosterone system (RAAS) in patients with moderate hypertension.

Clinical Details

Official title: An 8 Week, Double-blind, Randomized, Parallel-group Study to Compare the Effect of Aliskiren 300mg + Valsartan 320mg vs. Telmisartan 80mg + Ramipril 10mg on Biomarkers of the Renin-angiotensin-aldosterone System in Moderate Hypertension

Study design: Allocation: Randomized, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Basic Science

Primary outcome: Compare the effects of aliskiren + valsartan vs ramipril + telmisartan on 24-hour urinary aldosterone

Secondary outcome:

Compare the effects of aliskiren + valsartan vs ramipril + telmisartan on Plasma Renin Activity (PRA)and angiotensin II

Compare the effects of aliskiren + valsartan vs ramipril + telmisartan on mean sitting systolic and diastolic blood pressure

Assess safety and tolerability of aliskiren + valsartan and ramipril + telmisartan
