Key result
A combination of aliskiren (150 mg) and valsartan (80 mg) provided synergistic effects on renin release and lowered BP at least as effectively as higher dose monotherapy over 48 hours.
Why the study?
Does the combination of aliskiren and valsartan provide synergistic hormonal and blood pressure effects compared to monotherapy or placebo in mildly sodium-depleted normotensive individuals?
RCT (n=12)
Double-blind
randomized, four-period crossover
Does the combination of aliskiren and valsartan provide synergistic hormonal and blood pressure effects compared to monotherapy or placebo in mildly sodium-depleted normotensive individuals?
The combination of a renin inhibitor and an AT1 receptor antagonist provides synergistic effects on renin-angiotensin system hormone levels and prolonged blockade of angiotensin II.

Supports low-dose dual RAS blockade for efficient BP control; extends synergy data to short-term sodium-depleted settings.
Azizi et al. (2004) conducted an RCT in mildly sodium-depleted normotensive (n=12). Aliskiren and valsartan combination vs. Aliskiren 300 mg, valsartan 160 mg, and placebo was evaluated on Hormonal and blood pressure effects. A combination of aliskiren (150 mg) and valsartan (80 mg) provided synergistic effects on renin release and lowered BP at least as effectively as higher dose monotherapy over 48 hours.
