What Are PCSK9 Inhibitors?
PCSK9 inhibitors are a newer type of cholesterol-lowering medicine. They work by targeting a protein in the liver called PCSK9. This protein usually reduces the liver's ability to remove ‘bad’ LDL cholesterol from the blood. By blocking PCSK9, these medicines help the body clear more LDL cholesterol, lowering its levels.
Examples of PCSK9 inhibitors include alirocumab and evolocumab. These drugs are given by injection, usually every two to four weeks. They are typically prescribed alongside statins when cholesterol remains high or if statins are unsuitable.
How Do PCSK9 Inhibitors Prevent Heart Attacks?
High levels of LDL cholesterol increase the risk of fatty deposits in the arteries, leading to heart attacks. PCSK9 inhibitors dramatically lower LDL cholesterol, often by over 50%. This reduction means less chance of blockages forming in blood vessels that supply the heart.
Large clinical studies have shown that people using PCSK9 inhibitors have fewer heart attacks and strokes. These benefits are particularly noticeable in those who have already had a heart event or have very high cholesterol. Reducing LDL levels helps protect arteries and lowers overall cardiovascular risk.
Who Might Be Offered PCSK9 Inhibitors in the UK?
PCSK9 inhibitors are not for everyone but are vital for certain groups. In the UK, they are considered for people with very high cholesterol despite taking the maximum tolerated dose of statins. They may also be offered to those who cannot take statins due to side effects.
People with inherited conditions like familial hypercholesterolaemia may benefit the most. If you have already had a heart attack or are at high risk, your doctor may discuss this option with you. Access is typically through specialist referral after reviewing other treatments.
Are There Any Side Effects or Considerations?
PCSK9 inhibitors are usually well tolerated. The most common side effects are mild, such as reactions at the injection site or cold-like symptoms. Serious side effects are rare but can include allergic reactions.
These medicines are designed to be used alongside a healthy lifestyle. Eating well, exercising, and avoiding smoking all contribute to heart health. Regular check-ups with your healthcare team ensure your risk is managed appropriately.
What Are PCSK9 Inhibitors?
PCSK9 inhibitors are a type of medicine that helps to lower cholesterol. They work by blocking a protein in your liver called PCSK9. This protein usually stops the liver from removing ‘bad’ cholesterol (called LDL cholesterol) from your blood. When PCSK9 is blocked, your body can remove more ‘bad’ cholesterol and your cholesterol levels go down.
Some common PCSK9 inhibitor medicines are alirocumab and evolocumab. You usually get this medicine as an injection every two to four weeks. Doctors sometimes give PCSK9 inhibitors if statins do not work enough or if you cannot take statins.
How Do PCSK9 Inhibitors Prevent Heart Attacks?
Having high ‘bad’ cholesterol can block your blood vessels, which can cause heart attacks. PCSK9 inhibitors can reduce ‘bad’ cholesterol by half. This means your blood vessels are less likely to get blocked and you are less likely to have a heart attack.
Big studies have shown that people who take PCSK9 inhibitors have fewer heart attacks and strokes. This is especially helpful if you already have high cholesterol or had a heart problem before. Lowering ‘bad’ cholesterol helps keep your heart and blood vessels healthy.
Who Might Be Offered PCSK9 Inhibitors in the UK?
PCSK9 inhibitors are not given to everyone. In the UK, they are for people with very high cholesterol even after taking as much statin medicine as they can. They are also for people who cannot use statins because they get side effects.
People who have illnesses passed down in their family, like familial hypercholesterolaemia, may use these medicines. Your doctor may suggest PCSK9 inhibitors if you had a heart attack or you are at high risk. These medicines are usually given after your doctor has checked other treatments and may need you to see a specialist.
Are There Any Side Effects or Considerations?
PCSK9 inhibitors are mostly safe and do not cause many problems. Some people may get a sore red patch where they had the injection or have cold symptoms. Serious problems are rare, but tell your doctor if you feel unwell or have an allergic reaction.
You should still eat healthy food, move your body, and avoid smoking to help your heart. Go to regular doctor visits to make sure your health is okay and you are getting the right treatment.
Helpful tools or tips: Ask your nurse or doctor to show you how to give yourself the injection. You can use reminder apps or alarms to help you remember your medicine. Ask a family member or friend to help you keep track of injections and appointments.
Frequently Asked Questions
PCSK9 inhibitors are a class of medications that lower cholesterol by blocking the protein PCSK9, which leads to increased removal of LDL cholesterol from the blood.
By significantly lowering LDL cholesterol, a major risk factor for heart attacks, PCSK9 inhibitors reduce the likelihood of plaque buildup and subsequent heart attacks.
PCSK9 inhibitors are typically recommended for people at high risk of heart attacks who cannot achieve sufficient LDL cholesterol reduction with statins or have statin intolerance.
They are usually used in addition to lifestyle changes and other cholesterol-lowering medications, such as statins and ezetimibe.
Studies have shown that PCSK9 inhibitors can reduce LDL cholesterol by 50-60% and lower the risk of heart attacks and other cardiovascular events.
LDL cholesterol is often called 'bad' cholesterol because high levels contribute to plaque buildup in arteries, increasing heart attack risk.
No, they are generally used when statins are not enough or not tolerated; statins remain first-line therapy.

Yes, they are particularly useful for patients with this genetic condition who cannot reach cholesterol targets with other therapies.
LDL cholesterol levels typically decrease within weeks of starting therapy.
They can lower cholesterol significantly, but dangerously low levels are rare and should be monitored by a doctor.
They are targeted to those at highest risk or unable to achieve cholesterol goals with traditional methods, not for general use.
