Introduction[edit | edit source]
Calcium channel blockers (CCBs) are used in the management of hypertension, angina pectoris, supraventricular arrhythmias, subarachnoid hemorrhage, pulmonary hypertension, and for the prevention of migraine[1].
They work by preventing calcium from entering the cells of the heart and arteries. Calcium causes the heart and arteries to contract more strongly. By blocking calcium, calcium channel blockers allow blood vessels to relax and open.
Some calcium channel blockers can also slow the heart rate, which can further lower blood pressure[2].
