Strong and Sustained Antihypertensive Effect of Small Interfering RNA Targeting Liver Angiotensinogen

Abstract

99% suppression of circulating AGT. Maximal blockade of the renin-angiotensin system, achieved by valsartan+siRNA, yielded the greatest reduction in blood pressure and cardiac hypertrophy, whereas AGT lowering alone was as effective as conventional renin-angiotensin system inhibitors. Given its stable and sustained efficacy, lasting weeks, RNA interference may offer a unique approach to improving therapy adherence and treating hypertension.
