Last updated on November 13th, 2024 at 11:27 am

What are the Doses for Entresto? Well, Entresto (sacubitril/valsartan) is a groundbreaking medication used to treat heart failure with reduced ejection fraction (HFrEF). As a combination of two drugs, sacubitril and valsartan, Entresto works by reducing strain on your heart and improving its pumping ability. Correct dosing is very important in maximizing the medication’s benefits while minimizing potential risks.

Dosage Information

Initial Dosage

The starting dose of Entresto is important for setting the foundation of treatment. For most patients, the recommended initial dosage is 49 mg of sacubitril/51 mg of valsartan, taken twice daily. This dosage is typically given if you have never taken Entresto before or are switching from other heart failure treatments.

Why Start Low?

Starting at a lower dose helps you to minimize potential side effects and allows your body to adjust to the medication. It also helps your healthcare provider gauge how well you tolerates the drug before increasing the dosage.

Maintenance Dosage

Once have been on the initial dose for a period of time, your healthcare provider will adjust the dosage based on your response to the medication. The usual maintenance dose is 97 mg of sacubitril/103 mg of valsartan, taken twice daily. This higher dose is typically reached after the initial dose has been tolerated well.

How is the Dose Adjusted?

The maintenance dosage is determined based on various factors, including the patient’s overall health, response to the medication, and any side effects experienced. Regular follow-ups are essential to ensure the dosage remains optimal.

Maximum Dosage

The maximum recommended dose of Entresto is 97 mg of sacubitril/103 mg of valsartan, taken twice daily. Exceeding this dosage is not advised as it may increase the risk of adverse effects without providing additional therapeutic benefits.

Safety Considerations

Adhering to the prescribed maximum dosage ensures safety while maintaining the efficacy of the treatment. Dosages beyond this threshold have not been shown to provide additional benefits and can lead to unnecessary complications.

Dosage Adjustments

For Specific Conditions

Entresto is primarily prescribed for HFrEF, but dosage adjustments may be necessary based on the specific nature and severity of the condition. For instance, if you have advanced heart failure, you will require close monitoring and potential dosage adjustments.

How Does Condition Severity Affect Dosage?

If you have more severe heart failure symptoms, you will start at a lower dose and gradually increase, while those with milder symptoms might reach the maintenance dose more quickly. The goal is to balance effectiveness with safety.

Renal Impairment

If you have kidney problems, you will need adjusted dosages of Entresto. For those with moderate renal impairment (eGFR 30-59 mL/min/1.73 m²), the recommended dose is 49 mg/51 mg twice daily. In severe cases, the use of Entresto may be contraindicated.

Why Adjust for Kidney Function?

Renal impairment can affect how the body processes medications, necessitating dose adjustments to avoid potential accumulation and adverse effects.

Hepatic Impairment

If you have liver problems, particularly mild to moderate hepatic impairment, the initial dosage of Entresto for you is typically 49 mg/51 mg twice daily. In cases of severe hepatic impairment, the use of Entresto is generally not recommended.

Managing Liver Function

Monitoring liver function tests is crucial for patients with hepatic impairment to ensure safe and effective dosing. Dosage adjustments are made based on these tests and the patient’s overall response.

Administration Instructions

How to Take Entresto

You should take Entresto by mouth, with or without food. The medication is usually administered in tablet form, with doses split into two daily administrations.

Optimal Administration Tips

• Consistency: Take Entresto at the same times each day to maintain steady levels in the bloodstream.
• Swallow Whole: Tablets should be swallowed whole, not crushed or chewed, to ensure proper absorption.

Missed Dose

If a dose of Entresto is missed, it should be taken as soon as remembered unless it is almost time for the next dose. In this case, skip the missed dose and resume the regular dosing schedule. Doubling up on doses to make up for a missed one is not recommended.

Handling Missed Doses

• Timing: If a dose is missed but remembered within a few hours, it should be taken promptly.
• Avoiding Overdose: Do not take extra doses to compensate for a missed one, as this can lead to potential overdose.

Patient-Specific Considerations

Age

Elderly patients may be more sensitive to the effects of Entresto, particularly with regard to blood pressure. It is important for older adults to start at a lower dose and adjust based on their response.

Age-Related Adjustments

• Monitoring: Frequent monitoring is required to assess blood pressure and overall health.
• Dosage Adjustments: Dosage might be adjusted more cautiously for elderly patients.

Weight

Body weight can influence how Entresto is metabolized and its effects. While weight is not a primary factor in dosage adjustments, it can be considered in conjunction with other factors like renal function and overall health.

Impact of Weight on Dosage

• Weight Loss or Gain: Significant changes in weight might necessitate a review of the medication regimen.

Other Medications

Entresto may interact with other drugs, which can affect its efficacy or increase the risk of side effects. Common interactions include those with medications that impact blood pressure, potassium levels, or renal function.

Managing Drug Interactions

• Inform Healthcare Providers: Always inform healthcare providers about all other medications being taken.
• Regular Reviews: Medication reviews are essential to manage interactions effectively.

Side Effects and Monitoring

Common Side Effects

Entresto can cause side effects, particularly when starting the medication or adjusting the dose. Common side effects include:

• Hypotension: Low blood pressure can occur, especially when initiating treatment or increasing dosage.
• Hyperkalemia: Elevated potassium levels may be a concern.
• Renal Impairment: Changes in kidney function are possible.

Managing Side Effects

• Regular Monitoring: Regular blood tests to monitor potassium levels and kidney function.
• Reporting: Patients should report any significant side effects to their healthcare provider immediately.

Monitoring Requirements

Patients on Entresto should undergo regular monitoring to ensure the medication is working as intended and to catch any adverse effects early. Monitoring typically includes:

• Blood Pressure: Regular checks to monitor for hypotension.
• Kidney Function: Periodic tests to assess kidney health.
• Potassium Levels: Regular blood tests to monitor for hyperkalemia.

Drug Interactions

Interactions with Other Drugs

Entresto may interact with various medications, potentially altering its effectiveness or increasing side effects. Key interactions include:

• Diuretics: May enhance the risk of hypotension and electrolyte imbalances.
• NSAIDs: Can reduce the effectiveness of Entresto and increase the risk of renal impairment.
• Potassium-Sparing Diuretics: May increase the risk of hyperkalemia.

Managing Interactions

• Review Medications: Regular reviews of all medications being taken to manage interactions effectively.
• Adjust Dosages: Adjusting dosages or selecting alternative medications as needed.

Overdose Information

Signs of Overdose

Taking too much Entresto can lead to serious health issues. Signs of an overdose may include:

• Severe Hypotension: Markedly low blood pressure can cause dizziness, fainting, or shock.
• Severe Hyperkalemia: Excessive potassium levels may lead to heart rhythm problems.

What to Do

• Immediate Action: Seek emergency medical help if an overdose is suspected.
• Emergency Services: Contact emergency services or go to the nearest emergency room for prompt treatment.

Entresto Dosing Chart

The Entresto dosing chart is a guide to determine the correct dosage of Entresto (sacubitril/valsartan) for managing heart failure based on prior ACE inhibitor/ARB use and other clinical factors like kidney function and blood pressure.

Entresto is typically initiated at a lower dose, such as 24/26 mg or 49/51 mg twice daily, especially for patients new to ARB therapy, with low blood pressure, or moderate kidney impairment. Patients who are stable on ARBs or ACE inhibitors may start at a higher dose of 49/51 mg twice daily. The goal is to titrate to the target maintenance dose of 97/103 mg twice daily over 2-4 weeks, as tolerated, to maximize therapeutic effects while minimizing side effects. Regular monitoring of blood pressure, kidney function, and potassium levels helps ensure safe and effective dosing adjustments.
