Calcium channel blocker

22 ratings | 25214 views
Calcium channel blockers (CCB), calcium channel antagonists or calcium antagonists are a number of medications that disrupts the movement of calcium (Ca2+) through calcium channels. Calcium channel blockers are used as antihypertensive drugs, i.e. as medications to decrease blood pressure in patients with hypertension. CCBs are particularly effective against large vessel stiffness, one of the common causes of elevated systolic blood pressure in elderly patients. Calcium channel blockers are also frequently used to alter heart rate, to prevent cerebral vasospasm, and to reduce chest pain caused by angina pectoris. Despite their effectiveness, CCB's often have a high mortality rate over extended periods of use, and have been known to have multiple side effects. Potential major risks however were mainly found to be associated with short-acting CCBs. This video is targeted to blind users.

Surely there must be a human somewhere that could present this material… No matter how great the visual, for me, the patchy generated audio voice will always get me seeking an alternative...
