What is Amlodipine?
Amlodipine works by relaxing the blood vessels allowing blood to pass through the body more freely. It lowers your blood pressure by widening your blood vessels, which allows blood to be pumped around your body much easier. You may also recognise Amlodipine by its brand names of Istin and Amlostin.
This medication is highly effective in treating high blood pressure and coronary artery disease. These tablets are angioselective calcium channel blockers, which inhibit the movement of calcium ions into vascular smooth muscle cells and cardiac muscle cells. By doing so, they allow for an increase in blood flow around your heart and a decrease in pressure.
What is Amlodipine used for?
Amlodipine tablets are prescribed to treat high blood pressure and angina. By reducing our blood pressure level, we can prevent your chances of suffering from more serious complications such as strokes, heart attacks or heart disease.
Although it is not generally used to treat heart disease, it can be prescribed to prevent the chest pain this disease causes.
Amlodipine is only available on prescription and comes available as either a liquid or tablets.
