May take without regard to food. 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. However, CaCl ideally should be administered via a central line because of the risk of skin necrosis on extravasation. Nadolol. The effect of nisoldipine on blood pressure is principally a consequence of a dose-related decrease of peripheral vascular resistance. Cytosolic calcium concentration mediated by membrane gated influx of calcium is responsible for maintaining vascular smooth muscle tone. Nifedipine, a dihydropyridine calcium channel blocker, was once one of the most widely used medications for hypertension, but safety and tolerability concerns along with the introduction of new classes of antihypertensive medications and an increasing pool of data showing mortality benefit of other classes caused .
