The Mechanism of Action

Calcium channel blockers (CCBs) employment by preventing ca from entering the muscleman cell of the heart and profligate vessel walls.

Vertigo: A driblet in systemic blood press can lead to lightheadedness.
Flushing: A sensation of warmth or redness in the aspect or neck.

To palliate these effects, doctors ofttimes start patient on a low dose and titrate up easy base on tolerance.
