Cardiovascular
Medicines for Peripheral arterial disease
Narrowing of the arteries that supply the legs, usually from atherosclerosis, often causing cramping calf pain on walking — managed mainly by reducing cardiovascular risk, with stopping smoking, exercise, an antiplatelet and a statin at the core.

Quick answer
What is Peripheral arterial disease?
Peripheral arterial disease, or PAD, develops when the arteries carrying blood to the legs become narrowed by a build-up of fatty deposits in their walls, a process called atherosclerosis. The same process affects the arteries of the heart and brain, so PAD is best thought of as a sign that the whole circulation is at risk, not just a problem with the legs.
- How it is treated: The most important goal in PAD is to reduce overall cardiovascular risk, because the greatest danger is not usually to the leg but to the heart and brain.
- Self-care: Stopping smoking is the most important change of all and dramatically improves outcomes.
- When to seek help: See your GP if you develop cramping leg pain on walking that eases with rest, or if you have risk factors such as smoking, diabetes, high blood pressure or high cholesterol, so your circulation can be checked.
What it is
Peripheral arterial disease, or PAD, develops when the arteries carrying blood to the legs become narrowed by a build-up of fatty deposits in their walls, a process called atherosclerosis. The same process affects the arteries of the heart and brain, so PAD is best thought of as a sign that the whole circulation is at risk, not just a problem with the legs. The classic symptom is intermittent claudication: a cramping, aching or tired feeling in the calf, thigh or buttock that comes on with walking and eases within a few minutes of rest, only to return when walking starts again. Many people have no symptoms at all, while others first notice that wounds on the feet are slow to heal. Because PAD shares its risk factors with heart disease and stroke — smoking, high blood pressure, high cholesterol, diabetes and increasing age — finding it is an important opportunity to lower the risk of a future heart attack or stroke as well as to help the legs.
How it is treated
The most important goal in PAD is to reduce overall cardiovascular risk, because the greatest danger is not usually to the leg but to the heart and brain. Stopping smoking is the single most valuable step and is encouraged and supported at every opportunity. A supervised exercise programme — regularly walking to the point of discomfort, resting, then walking again — is a cornerstone of treatment and can genuinely improve walking distance over time. Alongside this, an antiplatelet medicine and a statin are offered to nearly everyone with PAD to protect the arteries, and blood pressure and diabetes are managed carefully. Good foot care is emphasised, since reduced blood supply makes the feet more vulnerable to injury and slow-healing wounds. Where claudication remains very limiting despite these measures, or where the blood supply to the leg is severely reduced, specialist vascular assessment can consider procedures to restore flow. Treatment is reviewed over time, focusing on both symptoms and long-term protection.

Symptoms that can point to Peripheral arterial disease
Peripheral arterial disease can be one cause of these symptoms. Each guide explains the other possible causes and the red-flag warning signs that mean you should get urgent help:
Beyond medication
Lifestyle and self-care
Stopping smoking is the most important change of all and dramatically improves outcomes. Regular walking exercise, even when it brings on discomfort, gradually improves how far you can walk. Eating a heart-healthy diet, keeping to a healthy weight, staying active and looking after your feet — checking them daily and treating small injuries promptly — all help protect both your legs and your circulation as a whole.
When to get help
When to see a doctor
See your GP if you develop cramping leg pain on walking that eases with rest, or if you have risk factors such as smoking, diabetes, high blood pressure or high cholesterol, so your circulation can be checked. It is important to seek prompt advice if leg pain comes on at rest or at night, if a wound or ulcer on the foot or leg is not healing, or if the skin changes colour. Seek urgent or emergency help if a leg or foot suddenly becomes painful, pale, cold, numb or weak, as this can mean the blood supply has been cut off and the limb is at risk and needs treating without delay.
Not sure how urgent it is? It is always OK to call NHS 111 for advice, day or night.
Answers
Peripheral arterial disease: frequently asked questions
What medicines are used for peripheral arterial disease?
The two mainstays are an antiplatelet medicine, which makes the blood less likely to form clots on the diseased artery walls, and a statin, which lowers cholesterol and helps stabilise the fatty deposits. Both are offered to nearly everyone with PAD, not mainly to ease leg symptoms but to protect the arteries and reduce the risk of a future heart attack or stroke. Medicines to control blood pressure and, where present, diabetes are also important. Alongside these, stopping smoking and a supervised walking programme do much of the work in improving symptoms and outcomes.
Will exercise make my leg pain worse?
It may feel uncomfortable at first, but supervised walking exercise is one of the most effective treatments for the cramping pain of claudication. The approach is to walk until the discomfort builds, rest until it eases, then walk again, repeating this regularly. Over weeks and months this can train the circulation to work more efficiently and noticeably improve how far you can walk before the pain comes on. It is safe and encouraged, and your healthcare team can guide you on how to do it.
Why is stopping smoking so important in PAD?
Smoking is a major cause of the artery damage behind PAD and strongly speeds the disease up, so stopping is the single most valuable thing you can do. It slows the narrowing of the arteries, improves walking distance over time and substantially lowers the risk of heart attack, stroke and losing the limb. Support to stop smoking is offered at every opportunity, and the benefits begin soon after you quit, making it well worth seeking help to succeed.
Can peripheral arterial disease become an emergency?
Usually PAD progresses slowly and is managed in clinic, but it can occasionally become urgent. If the blood supply to a leg drops severely you may get pain at rest, especially at night, or wounds that will not heal — these need prompt specialist assessment. More seriously, if a leg or foot suddenly turns painful, pale, cold and numb, the blood supply may have been blocked off completely, which is an emergency that needs treatment straight away to save the limb. Knowing these warning signs means you can act quickly.
