Entresto to Lisinopril Conversion

Heart failure remains a significant health concern globally, affecting millions of individuals and presenting a complex challenge in medical management. Among the various medications used for heart failure treatment, Entresto (sacubitril/valsartan) and lisinopril are prominent choices. Understanding the transition from Entresto to lisinopril or vice versa requires a comprehensive look at their mechanisms, dosage equivalencies, therapeutic benefits, side effects, and considerations for clinical practice.

Heart Failure and Medication Management

Heart failure is a chronic condition characterized by the heart’s inability to pump blood efficiently to meet the body’s needs. It leads to symptoms such as shortness of breath, fatigue, and fluid retention. Medications play a crucial role in managing heart failure by improving symptoms, reducing hospitalizations, and prolonging life expectancy.

Entresto and lisinopril are both widely used in the management of heart failure but belong to different classes of medications with distinct mechanisms of action and benefits.

Understanding Entresto (Sacubitril/Valsartan)

Entresto is a combination medication consisting of sacubitril, a neprilysin inhibitor, and valsartan, an angiotensin II receptor blocker (ARB). Neprilysin inhibition enhances the levels of beneficial peptides, such as natriuretic peptides, which promote vasodilation and diuresis, thereby reducing blood pressure and improving heart function. Valsartan blocks the effects of angiotensin II, further contributing to vasodilation and reducing the workload on the heart.

The combination of sacubitril and valsartan in Entresto has been shown to reduce cardiovascular mortality and hospitalizations for heart failure compared to traditional therapies like ACE inhibitors alone.

Lisinopril: Mechanism and Therapeutic Benefits

Lisinopril belongs to the class of medications known as angiotensin-converting enzyme (ACE) inhibitors. It works by inhibiting ACE, the enzyme responsible for converting angiotensin I into angiotensin II. By blocking this conversion, lisinopril reduces the production of angiotensin II, a potent vasoconstrictor, and aldosterone, a hormone that increases sodium and water retention. This results in vasodilation, reduced blood pressure, and improved cardiac output.

Lisinopril is effective in reducing symptoms of heart failure, improving exercise tolerance, and slowing the progression of the disease. It is commonly used as a first-line treatment in heart failure management.

Factors Influencing the Decision to Convert from Entresto to Lisinopril

Clinical Considerations

The decision to convert from Entresto to lisinopril or vice versa is influenced by several factors:

  • Clinical Stability: Patients should be clinically stable without acute exacerbations of heart failure symptoms.
  • Renal Function: Both medications are excreted via the kidneys, so renal function should be assessed before initiating or adjusting therapy.
  • Tolerability: Patient tolerance to side effects such as hypotension, hyperkalemia, and renal dysfunction should be evaluated.

Therapeutic Equivalency and Dosage Conversion

When transitioning from Entresto to lisinopril, or vice versa, it is essential to consider therapeutic equivalency and adjust dosages accordingly. The following are general guidelines for dosage conversion:

  • From Entresto to Lisinopril: Start lisinopril at a low dose (e.g., 2.5-5 mg once daily) and titrate upwards based on patient response and tolerability. The starting dose may vary depending on the patient’s renal function and previous medication regimen.
  • From Lisinopril to Entresto: Calculate the equivalent dose of valsartan in Entresto based on the patient’s current lisinopril dose and titrate according to clinical response.

Monitoring and Follow-Up

Patients transitioning between medications should be closely monitored for signs of worsening heart failure symptoms, electrolyte imbalances (e.g., hyperkalemia), and changes in renal function. Regular follow-up visits allow healthcare providers to assess treatment efficacy, adjust dosages as needed, and address any concerns or side effects.

Comparing Side Effects and Adverse Reactions

Both Entresto and lisinopril have well-established side effect profiles that healthcare providers must consider when managing patients with heart failure:

  • Entresto: Common side effects include hypotension, hyperkalemia, and renal dysfunction. Neprilysin inhibition may also increase the risk of angioedema in patients previously intolerant to ACE inhibitors.
  • Lisinopril: Common side effects include hypotension, dry cough (due to increased bradykinin levels), hyperkalemia, and renal dysfunction. Angioedema is a rare but serious adverse effect associated with ACE inhibitors.

Special Populations and Considerations

Certain patient populations require special considerations when converting between Entresto and lisinopril:

  • Renal Impairment: Dose adjustments are necessary in patients with impaired renal function to prevent medication accumulation and toxicity.
  • Pregnancy and Breastfeeding: Both medications are contraindicated during pregnancy due to potential harm to the fetus. Alternative therapies should be considered for women of childbearing age.


understanding the conversion from Entresto to lisinopril or vice versa is essential for optimizing heart failure management. Each medication offers distinct benefits and considerations based on its mechanism of action, side effect profile, and therapeutic equivalency. Healthcare providers play a crucial role in evaluating patient suitability, initiating therapy, and monitoring treatment efficacy. By considering clinical stability, renal function, therapeutic equivalency, and monitoring parameters, healthcare providers can effectively transition patients between Entresto and lisinopril to achieve optimal outcomes in heart failure management. Always consult with a healthcare professional before making any changes to medication therapy.
