Now, here comes the numerous controversies. A lot of articles stated that pts on CCB (calcium channel blockers) such as Nifepidine(Procardia) , Verpamil,(Calan) Diltiazem (Cardizem) shouldn't be taking calcium supplements. Calcium supplements ( may contain lead) may also decrease the efficacy of calcium channel . However, other studies suggested that Inadequate calcium intake may contribute to accelerated bone loss and density. .There is an ongoing debate whether these calcium channel blockers increase the risks of heart attacks.; as these meds block the transport of calcium across the muscle cell membrane.
Calcium. Calcium regulates the tone of the smooth muscles lining blood vessels, and population studies have found that people who have sufficient dietary calcium have lower blood pressure than those who do not. Hypertension itself increases calcium loss from the body. The effects of extra calcium on blood pressure, however, are mixed with some even showing higher pressure.
Effects of Anti-Hypertensive Drugs on Exercise. Certain anti-hypertensive medications, including diuretics and beta-blockers, can interfere with exercise capacity. ACE inhibitors or calcium-channel blockers are the best drugs for active individuals. However, patients who must take drugs that interfere somewhat with exercise capability should still adhere to an exercise program and consult a physician on how best to balance medications with exercise.
Dash Diet (Dietary Approaches to Stop Hypertension) is rcommended for Hypertensive pts. It's low salt to avoid more potassium loss. It's rich in fruits and vegetables. and nutrients and calcium obtained from foods naturally. They also contain other nutirents such as potassium and magnesium which help in the absorption of Ca.
