What are Amlodipine tablets?
Amlodipine is a calcium channel blocker that is primarily used in the treatment of high blood pressure.
Amlodipine has been used to treat high blood pressure and other complications since 1990 and is featured on the World Health Organisation's List of Essential Medicines.
Amlodipine is a prescription only medicine (POM) and is available in tablet form. It is available to buy in 5mg and 10mg doses
What is Amlodipine used for?
Amlodipine is a first line treatment option for high blood pressure. it is also widely used to treat chronic stable angina, and to prevent future heart disease, heart attacks and strokes.
Amlodipine helps to lower blood pressure by widening the blood vessels. As a result, blood is able to flow around the body easier, which also reduces the workload and pressure on the heart. By easing the pressure on the heart, amlodipine also reduces the risk of future heart attacks, strokes and developing heart disease.
How does Amlodipine treat high blood pressure?
Amlodipine works by inhibiting the ion channels within the cells of the heart and blood vessels from absorbing calcium. Blood vessels need calcium in order to restrict and contract, this forces the heart to work harder when pumping the blood around the body and as a result increases blood pressure.
Amlodipine's inhibitory effect on ion channels prevents excessive constrictions in the coronary arteries and reduces peripheral vascular resistance, which is the resistance that must be overcome in order to pump blood around the circulatory system in the body.
Amlodipine reduces contractions and relaxes the muscles within the blood vessels, this results in the widening of the blood vessels (vasodilation) which allows blood to flow through the body using less force from the heart.
Who can take Amlodipine?
Amlodipine is a prescription-only medicine. It can be prescribed to adults and children who are aged 6 years and over.
