Direct renin inhibitors. These capsules work further to ACEIs and ARBs in relaxing blood vessels however thru a different mechanism. Just one has been approved in the United States to this point: aliskiren (Tekturna).
Calcium channel blockers. These pills slow the motion of calcium into the coronary heart and blood vessel walls, keeping blood vessels dilated and enhancing the coronary heart’s pumping capacity.
