Calcium enters the muscles of your heart and blood vessels through tiny pores called calcium channels. How calcium channel blockers work CCBs reduce blood pressure by limiting the amount of calcium or the rate at which calcium flows into the heart muscle and arterial cell walls.

In doing this they lower the pressure in the blood vessels.

How calcium channel blockers work. Calcium channel blockers work by blocking the passage of calcium into the cells that need to contract. Calcium helps your heart and arteries contract properly to deliver blood and oxygen to your body. How do calcium-channel blockers work.

This causes blood vessels to relax and widen vasodilate improves oxygen supply to the heart and lowers blood pressure. CCBs usually blocks calcium that can enter into the muscle cells through tiny pores especially in the heart and blood vessels. Calcium-channel blockers work by stopping the calcium in your blood from entering the muscle cells in your blood vessel walls.

They are used to treat various conditions including high blood pressure angina Raynauds phenomenon and some abnormal heart rhythms arrhythmias. By blocking calcium calcium channel blockers allow blood vessels to relax and open. The relaxed vessels let blood flow more easily through them thereby lowering blood pressure.

Calcium channel blockers block the small pores in cells called L-type calcium channels that allow calcium to move in and out and widen blood vessels as well as affect the activity of nerve cells. How do calcium channel blockers work. When calcium enters these cells the muscles contract and tighten up making your blood vessels narrower.

These then relax causing the arteries to widen this is called vasodilation. Calcium-channel blockers also prevent angina by widening the coronary arteries that supply your heart. Calcium causes the heart and arteries to contract more strongly.

How do calcium channel blockers work. Calcium channel antagonists or calcium antagonists are the other names of Calcium channel blockers. Some calcium channel blockers also slow the heart rate.

But for many people with heart disease and high blood pressure those muscles are working too hard. Calcium channel blockers reduce the amount of calcium that can enter muscle cells in the heart and blood vessel walls via these channels. When this happens the cells cant work as usually and the muscles become more relaxed which is the reason why these drugs work.

Calcium channel blockers slow the rate at which calcium passes into the heart muscle and into the vessel walls. Calcium channel blocking agents restrict the amount of calcium entering cardiac and smooth muscle cells by blocking voltage-gated calcium channels. Calcium channel blockers are drugs used to lower blood pressure.

Calcium channel blockers are usually well absorbed through the git which means that they go through first pass metabolism However once entered into the blo. As a result it would reduce the blood pressure and your heart doesnt need to work so hard. Calcium channel blockers are used as antihypertensive drugs ie as medications to decrease blood pressure in patients with hypertension.

Thus calcium-channel blockers are smooth-muscle dilators and have a negative inotropic effect on the working myocardial cells of the atria and ventricles. This helps to lower your blood pressure. In coronary and peripheral arterial smooth muscle and the heart inhibition of Ca2 entry blunts the ability of Ca2 to serve as an intracellular messenger.

Calcium channel blockers lower your blood pressure by preventing calcium from entering the cells of your heart and arteries. Calcium-channel blockers restrict how much calcium can enter the muscle cells in your blood vessels. This relaxes the vessels.

Calcium channel blockers CCB calcium channel antagonists or calcium antagonists are a group of medications that disrupt the movement of calcium Ca2 through calcium channels. Calcium channel blockers CCBs dilate the arteries reducing pressure within and making it easier for the heart to pump blood and as a result the heart needs less oxygen. By reducing the hearts need for oxygen calcium channel blockers relieve or prevent angina chest pain.

This means your blood has less space to flow through raising your blood pressure. They work by slowing the movement of calcium into the cells of the heart and blood vessel walls which makes it easier for the heart. Calcium-channel blockers sometimes called calcium antagonists are a group of medicines that affect the way calcium passes into certain muscle cells.
