Doses of up to 800 mg can be given as two divided doses to be taken with food. David McAuley, Pharm.D. Absorption:Calcium channel antagonists are absorbed well orally, however many have low bioavailability due to hepatic first-pass metabolism, primarily by CYP3A4. By blocking calcium, calcium channel blockers allow blood vessels to relax and open. Your body uses ions (atoms with an electrical charge) in electrolytes to transport things into and out of your cells. 0000009287 00000 n The effect of felodipine on blood pressure is principally a consequence of a dose-related decrease of peripheral vascular resistance in man, with a modest reflex increase in heart rate. 0000186357 00000 n Wrist blood pressure monitors: Are they accurate? This is especially true with verapamil, which strongly affects the timing and strength of your heartbeat, meaning it can be deadly if you take too much. Take on an empty stomach (1 hr before or 2 hrs after a meal). The binding of nifedipine to voltage-dependent and possibly receptor-operated channels in vascular smooth muscle results in an inhibition of calcium influx through these channels. May be given once daily or in 2 divided doses. Vegetarian diet: Can it help me control my diabetes? 0000208153 00000 n As a result, verapamil relaxes blood vessels and increases the supply of blood and oxygen to the heart while reducing its workload .
