Heart Failure Medications: An In-Depth Overview

Heart failure is a chronic condition in which the heart cannot pump blood efficiently to meet the body’s needs. Medicinal therapy plays a crucial role in both managing symptoms and slowing the progression of the disease. This guide offers a detailed look at heart failure medications, including drug classes, common prescriptions, how they work, side effects, and important discussion points for patients and caregivers.

Why Are Medications Necessary for Heart Failure?

Medications for heart failure help:

Reduce the heart’s workload and improve its pumping efficiency
Lower blood pressure and control fluid buildup
Decrease risk of complications and hospitalizations
Improve quality of life and longevity

Because heart failure often gets worse over time, the correct combination of medicines can make a significant difference in managing symptoms and slowing progression.

Main Classes of Heart Failure Medications

Doctors typically prescribe several different drugs from distinct categories, each targeting a unique aspect of the condition. The following table summarizes the primary classes:

Drug Class	How It Works	Common Examples
ACE Inhibitors	Relax blood vessels, lower blood pressure, reduce strain on the heart	Enalapril, Lisinopril, Captopril
ARBs	Same as ACE inhibitors, alternative for those intolerant to ACE inhibitors	Losartan, Valsartan, Candesartan
ARNIs	Combine an ARB and a neprilysin inhibitor to increase benefit	Sacubitril-Valsartan
Beta Blockers	Slow heart rate, lower blood pressure, decrease demand on the heart	Carvedilol, Metoprolol, Bisoprolol
Diuretics	Promote fluid loss through urination, lower blood pressure, reduce swelling	Furosemide, Torsemide, Bumetanide
Aldosterone Antagonists	Increase sodium and water excretion, decrease blood pressure	Spironolactone, Eplerenone
SGLT2 Inhibitors	Promote kidney excretion of glucose and sodium, may reduce mortality	Dapagliflozin, Empagliflozin
Other Drugs	Vasodilators, anticoagulants, cholesterol-lowering medications as indicated	Hydralazine, Warfarin, Statins

How Are Drugs Chosen for Heart Failure Treatment?

Medication selection depends on several factors:

Type of heart failure: Reduced ejection fraction (HFrEF) vs. Preserved ejection fraction (HFpEF)
Severity of symptoms and stage of disease
Other conditions: Kidney disease, diabetes, high blood pressure, etc.
Previous responses to medications
Potential interactions and side effects

Most patients will receive medicines from multiple drug classes. Dosing is often started low and gradually increased to the optimal level for each individual.

Foundational Therapies for Heart Failure with Reduced Ejection Fraction (HFrEF)

Current expert guidelines recommend the following four classes as core therapies for HFrEF:

Beta blockers
RAAS inhibitors: ARNI preferred, ACE inhibitor or ARB as alternatives
Aldosterone antagonists
SGLT2 inhibitors

Specific drugs within each class are chosen based on individual patient characteristics and tolerance. According to clinical evidence, using one medication from each class can help lower the risk of hospitalization and death.

10 Frequently Prescribed Heart Failure Medications

Here are ten medications often prescribed for heart failure, with basic usage guidelines:

Carvedilol (Coreg, Coreg CR): Beta blocker; typically taken twice daily or once daily (CR version) with food.
Enalapril (Vasotec): ACE inhibitor; taken once or divided in two doses daily.
Lisinopril (Prinivil, Zestril): ACE inhibitor; usually once daily.
Furosemide (Lasix): Diuretic; once daily, often in the morning to minimize nighttime urination.
Losartan (Cozaar): ARB; usually once daily.
Metoprolol (Lopressor, Toprol XL): Beta blocker; immediate- and extended-release forms available.
Valsartan (Diovan): ARB; once or twice daily.
Sacubitril-Valsartan (Entresto): ARNI; twice daily, as directed.
Spironolactone (Aldactone): Aldosterone antagonist; once daily.
Dapagliflozin (Farxiga): SGLT2 inhibitor; once daily.

The right medication and combination for each patient is determined by their medical history, symptoms, and how well they tolerate the drugs.

How Do Heart Failure Medications Work?

Each drug class operates differently to relieve symptoms and improve heart function. Here’s a closer look:

ACE inhibitors and ARBs: Improve blood flow by making blood vessels wider (vasodilation) and lower blood pressure, helping the heart pump more efficiently.
ARNI (sacubitril-valsartan): Addresses two pathways—lowering blood pressure and increasing levels of natural substances that help the heart and blood vessels function better.
Beta blockers: Slow the heartbeat and decrease its force, reducing strain and lowering oxygen demand.
Diuretics: Remove excess fluid, reducing swelling and making breathing easier.
Aldosterone antagonists: Promote excretion of sodium and water, preventing harmful heart and vascular remodeling.
SGLT2 inhibitors: Help the kidneys remove extra glucose and sodium, which may lower blood volume and reduce heart failure-related hospitalizations.

Potential Side Effects of Heart Failure Medicines

All medications can cause side effects. Commonly reported issues include:

ACE Inhibitors: Dry cough, skin rash, dizziness, potential kidney dysfunction
ARBs: Dizziness, headache
ARNIs: Low blood pressure, dizziness, cough
Beta Blockers: Fatigue, weakness, dizziness, possible worsening of asthma
Diuretics: Increased urination, thirst, electrolyte abnormalities (low potassium or sodium), sensitivity to sunlight
Aldosterone antagonists: Nausea, stomach cramps, diarrhea, elevated potassium levels
SGLT2 inhibitors: Urinary tract infections, increased thirst, risk of low blood pressure

Talk with your healthcare provider about any new or unusual symptoms, and do not stop taking medication without medical advice.

Important Questions to Ask Your Doctor

Building an effective heart failure treatment plan means staying informed and engaged with your care team. Here are key questions to discuss:

What type of heart failure do I have, and how does it impact my medication choices?
Why is each medicine part of my treatment plan?
How often and when should I take my drugs?
What side effects should I watch for?
Will these medicines interact with my other prescriptions or supplements?
Are there regular lab tests I need with any of these drugs?
Could my medicine options change as my condition or lifestyle changes?

Monitoring and Long-Term Follow-Up

Managing heart failure is a lifelong process. Your doctor will:

Regularly review your symptoms and overall health
Adjust doses or add new medicines as needed
Monitor blood tests for kidney function and electrolyte levels, especially with diuretics and aldosterone antagonists
Help you develop strategies to take medicines correctly and promptly report problems

Lifestyle and Complementary Measures

Medicines are most effective when combined with other treatments, including:

Following a heart-healthy diet (low sodium, balanced nutrients)
Maintaining a regular exercise routine, as guided by your provider
Avoiding tobacco, limiting alcohol
Managing other conditions such as diabetes or high blood pressure
Monitoring daily weight for signs of fluid retention

Integrating non-drug strategies can improve the effectiveness of your medication regimen and overall prognosis.

Recent Advances in Heart Failure Therapy

Ongoing medical research has resulted in new treatment options for heart failure, such as:

SGLT2 Inhibitors: Dapagliflozin and empagliflozin, originally designed for diabetes, have shown benefits for heart failure patients even without diabetes.
Sacubitril-Valsartan (ARNI): Combining ARB with a neprilysin inhibitor has been proven to reduce hospitalizations and deaths.
Vericiguat (Verquvo): A new oral medication for chronic heart failure, taken once daily, that works on the nitric oxide pathway to aid heart function.

These innovations offer more choices to tailor therapy to each individual’s needs.

Frequently Asked Questions (FAQs)

What happens if I miss a dose of my heart failure medication?

If you forget a dose, take it as soon as you remember unless it is close to the next scheduled dose—never double up. If you miss doses frequently, talk to your pharmacist or doctor about strategies to stay on track.

Do heart failure medicines cure the condition?

While medicines do not cure heart failure, they can substantially improve symptoms, slow progression, and reduce risks of complications.

Can lifestyle changes allow me to stop taking my medications?

Lifestyle improvements can enhance how well your medications work, but most people with heart failure need to continue drug therapy long term. Never stop without consulting your provider.

Why am I taking multiple heart failure medications?

Each drug class targets a different part of the condition. Combining medications allows for better symptom control and improved outcomes.

Are there alternative treatments for heart failure?

Besides medications, some cases may benefit from implantable devices, surgery, or advanced therapies. These approaches are customized to your medical status and risks.
