verapamil Inhibits calcium ion influx across cell membrane during cardiac depolarization; produces relaxation of coronary vascular smooth muscle peripheral vascular smooth muscle; dilates coronary vascular arteries; decreases SA/AV node HTN, angina, SVT, atrial flutter, afib
Procardia nifidipine Inhibits calcium ion influx across cell membrane during cardiac depolarization, produces relaxation of coronary vascular smooth muscle, dilates coronary vascular arteries, .>myocardial O2 delivery in pts w/vasospastic angina, dilates peripheral arteries HTN, vasopastic angina, chronic stable angina
Cardizem diltiazem Inhibits calcium ion influx across cell membrane during cardiac depolarization, produces relaxation of coronary vascular smooth muscle, dilates coronary arteries, slows SA/AV node conduction times, dilates peripheral arteries; decreased angina. CCB Angina, afib, atrial flutter, SVT
Lotrel amlodipine-benazepril Inhibits calcium ion influx across cell membrane during cardiac depolarization; produces relaxatn of coronary vascular smooth muscle & peripheral vascular smooth muscle; dilates crnary vascular arteries; > myocardial O2 delivery in pt w/vasospastic angina HTN
Catapres clonidine Inhibits sympathetic vasomotor center in CNS, which reduces impulses in sympathetic nervous system; B/P; pulse rate, cardiac output decreased; prevents pain signal transmission in CNS by α­adrenergic receptor stimulation of the spinal cord; < b/p in HTN HTN
