Does Entresto Cause Low Blood Pressure?
Yes, low blood pressure (hypotension) is a known side effect of Entresto (sacubitril/valsartan), a drug used to treat heart failure. Clinical trials showed hypotension in 18% of patients on Entresto versus 12% on valsartan alone.[1] It's often dose-dependent and more common in those starting treatment or with dehydration, low sodium, or concurrent diuretics.
How Common Is Hypotension with Entresto?
In the PARADIGM-HF trial, the primary study supporting FDA approval, symptomatic hypotension occurred in 14% of Entresto users compared to 9.2% in the enalapril group.[1][2] Prescribing information lists hypotension as very common (≥10%), with risks rising in elderly patients or those with renal impairment.[3]
Why Does Entresto Lower Blood Pressure?
Entresto combines sacubitril, a neprilysin inhibitor that boosts natriuretic peptides to promote vasodilation and natriuresis, with valsartan, an ARB that blocks angiotensin II. This dual action relaxes blood vessels more than ACE inhibitors alone, reducing blood pressure.[1][4] Effects peak within 2 hours of dosing and stabilize over weeks.
What Are Symptoms and Risks of Low Blood Pressure on Entresto?
Symptoms include dizziness, lightheadedness, fainting, fatigue, or blurred vision, especially when standing (orthostatic hypotension). Severe cases can lead to falls, kidney injury, or shock. Risk factors: starting dose, volume depletion, or drugs like diuretics/NSAIDs.[3][5] Monitor blood pressure closely at initiation; dose adjustments or pauses may be needed.
How Do Doctors Manage Hypotension from Entresto?
Start at 24/49 mg twice daily, titrating up over weeks if tolerated. If hypotension occurs, reduce dose to 49/51 mg, hold temporarily, or correct fluids/electrolytes. Avoid in patients with systolic BP <100 mmHg.[3] About 10-15% need dose reduction due to low BP in trials.[1]
Does Entresto Lower BP More Than Other Heart Failure Drugs?
| Drug | Hypotension Rate in Trials | Notes |
|------|-----------------------------|-------|
| Entresto | 14-18% | Higher vasodilation[1] |
| Enalapril (ACEI) | 9-12% | Less neprilysin effect[1] |
| Carvedilol (beta-blocker) | 5-10% | Bradycardia more common[6] |
| Spironolactone | 1-5% | Hyperkalemia risk instead[7] |
Entresto causes more hypotension than ACE inhibitors but offers better survival benefits in HFrEF.[2]
Who Should Avoid Entresto Due to BP Concerns?
Contraindicated in history of angioedema, pregnancy, or with ACEIs/ARBs. Use caution in BP <100/60 mmHg, renal artery stenosis, or severe liver disease. Not for HFpEF without trials data.[3]
