Does Entresto (Sacubitril/Valsartan) Lower Blood Pressure?
Yes, Entresto (sacubitril/valsartan) effectively lowers blood pressure through its dual mechanism of action as an angiotensin receptor-neprilysin inhibitor (ARNI). 1, 2
Mechanism and Blood Pressure Lowering Effects
- Entresto combines neprilysin inhibition (sacubitril) with angiotensin II receptor antagonism (valsartan), which increases endogenous natriuretic peptides while simultaneously inhibiting the renin-angiotensin-aldosterone system 2
- The valsartan component in Entresto provides significant blood pressure reduction through angiotensin II receptor blockade, with FDA data showing that valsartan alone produces dose-related decreases in systolic and diastolic blood pressure of approximately 6-9/3-5 mmHg at 80-160 mg doses and 9/6 mmHg at 320 mg 1
- Clinical studies have demonstrated that sacubitril/valsartan produces greater blood pressure reduction than valsartan alone, particularly in patients with resistant hypertension 3
Clinical Evidence in Different Populations
- In patients with heart failure and preserved ejection fraction (HFpEF) who had resistant hypertension, sacubitril/valsartan reduced systolic blood pressure by 4.8 mmHg at 4 weeks and 3.9 mmHg at 16 weeks compared to valsartan alone 3
- For patients with apparent mineralocorticoid receptor antagonist (MRA)-resistant hypertension, the blood pressure reduction was even more pronounced: 8.8 mmHg at 4 weeks and 6.3 mmHg at 16 weeks compared to valsartan alone 3
- In maintenance hemodialysis patients with chronic heart failure, sacubitril/valsartan effectively reduced both systolic and diastolic blood pressure before dialysis 4
- Real-world data from hypertensive heart failure patients showed significant reductions in blood pressure (systolic: 12.8 ± 21.2 mmHg, diastolic: 7.1 ± 16.5 mmHg) following sacubitril/valsartan treatment 5
Regulatory Status and Clinical Applications
- While sacubitril/valsartan was initially developed for hypertension, it is currently FDA-approved primarily for reducing hospitalization and risk of cardiovascular death in patients with heart failure with reduced ejection fraction (HFrEF) in the United States and Europe 2, 6
- However, it has been approved as an antihypertensive agent in some countries including China and Japan 5
- The 2024 European Society of Cardiology guidelines acknowledge that sacubitril/valsartan has BP-lowering properties but note that it awaits supportive evidence from cardiovascular outcomes trials prior to guideline endorsement for routine use in hypertension 6
Potential Benefits in Specific Hypertension Phenotypes
- Sacubitril/valsartan may be particularly effective for age-related hypertension phenotypes such as resistant hypertension characterized by systolic (central) hypertension and/or nocturnal hypertension 7
- In patients with apparent resistant hypertension, 47.9% achieved controlled systolic blood pressure by Week 16 with sacubitril/valsartan compared to 34.3% with valsartan alone 3
- For those with apparent MRA-resistant hypertension, blood pressure control rates were 43.6% with sacubitril/valsartan versus 28.4% with valsartan alone 3
Safety Considerations
- The most common side effect of sacubitril/valsartan is hypotension, which requires monitoring, particularly when initiating therapy 2
- In hemodialysis patients, there was an increased incidence of hyperkalemia during sacubitril/valsartan treatment, highlighting the need for electrolyte monitoring in certain populations 4
- Like other agents affecting the renin-angiotensin system, sacubitril/valsartan should not be combined with ACE inhibitors or direct renin inhibitors due to increased risk of adverse events 8
In conclusion, Entresto (sacubitril/valsartan) demonstrates significant blood pressure-lowering effects through its dual mechanism of action, with evidence showing superior blood pressure reduction compared to valsartan alone, particularly in patients with resistant hypertension.
