Drugs used to treat preventable diseases carry serious risks (Part 2 - ARBs)

Posted Jun 22 2010 7:02am

Part 2:

Angiotensin receptor blockers - anti-hypertensive drugs – linked to lung cancer and heart-related deaths

lungs

Angiotensin-receptor blockers (ARBs) are used to to treat hypertension, heart failure, and diabetic nephropathy (kidney dysfunction). They work by blocking a hormone system that regulates vascular tone and water and salt balance to control blood pressure.

Because angiotensin can affect cell survival and angiogenesis (formation of new blood vessels), two important factors in tumor growth, angiotensin is thought to play a role in cancer progression.1 To determine whether taking ARBs affected cancer risk, scientists performed a meta-analysis of several studies to uncover any possible links between ARBs and cancers. They determined that ARBs carry a increased risk of new diagnosis of any cancer (8%), and a significantly higher risk of lung cancer (25%).2

One ARB in particular, olmesartan (Benicar), is now under scrutiny by the FDA for potential cardiovascular risks. In a clinical trial testing olmesartan’s efficacy for slowing kidney damage in diabetics, there were increased rates of sudden cardiac death and death from heart attack and stroke in the subjects taking the drug compared to those taking placebo.3

In my practice, and from results recorded from members at DrFuhrman.com , even people with dramatically high blood pressure readings and dramatically high cholesterol levels have successfully returned their levels to normal without medications. In fact, as published in the medical journal Metabolism, the nutritarian diet is the most effective method to lower high cholesterol, even more effective than drugs.4 If people were very informed of these results and the risks involved with taking medications many more would certainly embrace nutritional excellence as therapy. High cholesterol and high blood pressure are lifestyle-created conditions, and the safest and most effective treatment is a high nutrient diet and exercise.
