Amlodipine BesylateAmlodipine besylateHow does it work? Amlodipine besylate belongs to a group of medicines called calcium channel blockers. These dilate the blood vessels in the body and are used to treat high blood pressure and angina. Amlodipine slows the movement of calcium through muscle cells in the walls of blood vessels. Calcium is required for these muscle cells to contract, thus amlodipine causes the muscle cells to relax. This causes the blood vessels to dilate. Blood pressure depends on the force with which the heart pumps the blood, and on the diameter of blood vessels and the volume of blood in circulation. Blood pressure increases if the blood vessels are narrow or if the volume is high. Dilating the blood vessels in the extremities therefore decreases blood pressure. The coronary arteries in the heart are also dilated by amlodipine, and this allows more blood, and therefore oxygen, to be delivered to the heart at any time. Overall the heart is required to use less effort to pump blood around the body, and is also given a greater oxygen supply. This prevents the pain of angina, which would normally be brought on because of a lack of oxygen supply to the heart. What is it used for? A severe form of angina pectoris, not caused by exertion High blood pressure Prevention of angina pectoris Warning! This medicine is not recommended for use in children.
