Why are calcium channel blockers bad for you?

Calcium channel blockers are prescribed for hypertension (high blood pressure), heart arrhythmias (irregular heart beats), and angina (chest pain.) Unfortunately, research shows that these drugs make one far more susceptible to dying of a heart attack (resulting in early death) as well as potentiating cancer.

Are calcium blockers safe?

Calcium channel blockers are generally safe, but like any medication, need to be taken properly and with care. To lessen the chance of interactions, always tell your doctor about other medications you’re taking.

What is the most effective calcium channel blocker?

The dihydropyridine calcium channel blockers, a group that includes amlodipine, felodipine and lacidipine, are a common choice for treatment of hypertension. Amlodipine, which is both low cost and taken once daily, is the one of the most commonly prescribed agents.

What are the two types of calcium channel blockers?

There are two distinct chemical classes of CCBs: the dihydropyridines (such as nifedipine and amlodipine) and the nondihydropyridines (diltiazem and verapamil).

Who shouldn’t take calcium-channel blockers?

Calcium channel blockers may be used to treat heart failure caused by high blood pressure when other medications to lower blood pressure do not work. Calcium channel blockers generally should not be used if you have heart failure due to systolic dysfunction.

What is the best time of day to take calcium-channel blockers?

Calcium channel blockers should be taken at the same time each day. It is better to take them before or during a meal. If you are taking a calcium channel blocker you should avoid grapefruit juice as it can increase the levels of drug in your body and increase the risk of side effects.

What is a natural calcium blocker?

Magnesium is an example of a nutrient that acts as a natural CCB. Research has shown that higher levels of magnesium block the movement of calcium. In animal studies, magnesium supplementation seemed to be most effective in the young with elevated blood pressure, before they developed hypertension.

Which is better beta blocker or calcium blocker?

Beta blockers can also prevent further heart attacks and death after a heart attack. Calcium channel blockers (CCBs) dilate the arteries, reducing pressure within and making it easier for the heart to pump blood, and, as a result, the heart needs less oxygen.

Can I stop taking calcium channel blockers?

Don’t stop taking your calcium-channel blockers unless your doctor tells you to. Stopping calcium-channel blockers suddenly can cause pain and tightness in your chest (angina).

Similarly, normal doses of vitamin D-3 (4,000 IU a day or less) do not significantly affect calcium levels, and may be taken with calcium-channel blockers.

Which is better diltiazem or amlodipine?

Although both agents were well tolerated and reduced blood pressures consistently over the 10-week test period, amlodipine was more effective than diltiazem in reducing systolic and diastolic blood pressures to the target pressures of < 140 mm Hg systolic and < 90 mm Hg diastolic over a range of doses widely used in ...

  • Constipation.
  • Dizziness.
  • Fast heartbeat (palpitations)
  • Fatigue.
  • Flushing.
  • Headache.
  • Nausea.
  • Rash.

Do calcium channel blockers affect the kidneys?

Calcium channel or entry blockers (CEBs) exert important vascular and tubular effects on the kidney. These renal effects include an enhancement of glomerular filtration rate (GFR), renal blood flow (RBF), and electrolyte excretion.

What is an alternative to amlodipine?

There are several other calcium channel blockers that work in the same way as amlodipine. They include nifedipine, felodipine, lacidipine and lercanidipine. There are other calcium channel blockers, such as diltiazem and verapamil, that have other effects on the heart.

Do calcium channel blockers affect sleep?

Use of calcium channel blockers was associated with significant reduction in total sleep time (-41 min, P = 0.005) and 8% lower sleep efficiency (P = 0.004). No other antihypertensive medication, including diuretics and beta-blockers, was associated with sleep impairment.

Can diltiazem cause weight gain?

Heart failure has gotten worse in some people taking this drug. If you have heart failure, talk with your doctor.

A severe skin reaction (Stevens-Johnson syndrome/toxic epidermal necrolysis) may happen.

Are calcium channel blockers safe long-term?

In a recent casecontrol study, long-term use of calcium channel blocking drugs was associated with a greater-than-twofold increased breast cancer risk. If prospectively collected data confirm that calcium channel blocker use increases breast cancer risk, this would have major implications for hypertension treatment.

What are 4 worst blood pressure drugs?

Both Yancy and Clements point out that those medications include: thiazide diuretics (chlorthalidone, hydrochlorothiazide) ACE inhibitors (benazepril, zofenopril, lisinopril, and many others) calcium channel blockers (amlodipine, diltiazem)

While on beta-blockers, you should also avoid eating or drinking products that have caffeine or taking over-the-counter cough and cold medicines, antihistamines, and antacids that contain aluminum. You should also avoid drinking alcohol, because it can decrease the effects of beta-blockers.

Is magnesium a calcium blocker?

Oral magnesium acts as a natural calcium channel blocker, increases nitric oxide, improves endothelial dysfunction, and induces direct and indirect vasodilation.

What is safest beta blocker?

Cardioselective. A number of beta blockers, including atenolol (Tenormin) and metoprolol (Toprol, Lopressor), were designed to block only beta-1 receptors in heart cells. Since they don’t affect beta-2 receptors in blood vessels and the lungs, cardioselective beta blockers are safer for people with lung disorders.

Is diltiazem hard on the kidneys?

Diltiazem monotherapy was confirmed to be an effective antihypertensive agent. Although mean arterial pressure was reduced from 121 to 108 mm Hg, diltiazem had no overall effect on glomerular filtration rate, renal plasma blood flow, salt and water excretion, or body fluid composition.

Can you drink alcohol while taking calcium channel blockers?

Interactions With Calcium Channel Blockers Do not drink alcohol while taking a calcium channel blocker. Alcohol interferes with the effects of the drug and increases the side effects. Taking other blood pressure medications in combination with a calcium channel blocker may cause a sudden drop in blood pressure.

Do calcium blockers cause bone loss?

Calcium channel blockers do not affect mineralization of the bone, nor do they increase the risk for osteoporosis. One group found that people on calcium channel blockers may have a slightly higher risk of fractures; however, that was thought to be due to an increased number of falls, especially in the elderly.

Can you exercise on calcium channel blockers?

Previous studies have shown that treatment with beta-blockers tends to reduce exercise capacity, whereas treatment with calcium blockers may preserve or even improve exercise tolerance.

What are the alternatives to calcium channel blockers?

Worldwide, beta blockers and vasodilators, especially the calcium-channel blockers, are the most commonly used alternative agents. Several studies comparing these 2 classes of medications are reviewed.
