FDA panel recommends wider use for cholesterol-lowering drug Crestor

December 15, 2009 |  4:00 pm

A Food and Drug Administration advisory panel recommended today that drug-maker AstraZeneca be allowed to expand the labeling on its cholesterol-lowering drug Crestor to include some people who do not have high cholesterol levels. That could allow as many as 6 million more people to use the drug, preventing about 50,000 heart attacks, strokes and deaths each year, experts said.

The FDA is not required to follow the recommendations of its advisory panels, but it usually does.

Crestor, known generically as rosuvastatin, is one of a family of drugs called statins that block production of cholesterol in the liver. More than 13 million Americans take statins regularly and worldwide sales total more than $33 billion per year, most of that in the United States.

But many studies have shown that statins have a variety of other effects, including protection against glaucoma, cataracts, macular degeneration, and perhaps even flu. They also reduce inflammation, which plays a key role in heart disease. The inflammation specifically linked to cardiovascular problems is characterized by a rise in levels of C-reactive protein, or CRP. Crestor, and perhaps other statins as well, apparently reduce the risk of heart attacks by reducing levels of CRP in addition to reducing cholesterol.

In a study of nearly 18,000 people with high levels of CRP but normal or slightly elevated levels of cholesterol, researchers found that Crestor reduced the risk of death from heart disease by 20%. Overall, there was a 44% reduction in deaths, strokes, heart attacks and hospitalizations to clear clogged arteries. The planned four-year study was terminated after only two years because the results were so dramatic. That study was the primary basis for AstraZeneca's application to expand the labeling for Crestor.

That study showed some potential side effects of the drug. About 2.8% of patients taking the drug developed diabetes, compared with 2.3% of those taking a placebo. But all drugs in the class do this, and experts think the drugs may simply make latent diabetes appear earlier. There were also 13 deaths due to gastrointestinal disorders among those taking Crestor, compared with only one in the placebo group. Experts think this is probably due to chance, but recommended that monitoring continue.

Sales of Crestor totaled $3.6 billion last year, and experts predicted that FDA approval of the labeling change could add an extra $500 million. Crestor is one of the most expensive statins, costing about $3.45 per day. Simvastatin (Zocor) is now sold in a generic form and the bestselling statin, Pfizer's Lipitor, will be available as a generic in 2011.

AstraZeneca estimates that about half of the patients who suffer a heart attack do not have high cholesterol levels. Heart disease kills about 450,000 people in the United States each year. An estimated 935,000 Americans have heart attacks each year and 795,000 have strokes.

This is an amazingly one-sided written article. I would hope that someone that would write such an article would do a little more research as to the possible side effects. The most common are liver damage and muscle deterioriation. On a personal note, my father-in-law had taken Lipitor for 14 years, to eventually notice that his legs were having difficulty walking without pain. Due to the fact that he was 79 at the time, doctors just thought it was due to old age. Being educated in the harms of statins and alternatives as well as my husband being a medical professional, we knew this was a possible side effect. He had his blood tested by his doctors to determine the reason he was having difficulty, and they found it to be muscle deterioratin due to the statin he was taking, Lipitor. After pulling him off and allowing him to take a natural plant sterol / omega three product, he has been able to keep his cholestorol in a safe range. I hope this is helpful for others ;-)

When Uffe Ravnskov, MD PhD actually went back and looked at the peer-reviewed medical literature he found 38 cohort studies where people with higher cholesterol on average lived longer and no published studies showing the converse. Not a bad end-point to look at. Of course, this still leaves out the whole issue of statin side effects. Weren't they saying just a couple weeks back that statins cured swine flu? Now they want to give them to healthy people with normal cholesterol. This is embarrassing, just creepy drug pushers. 20 Billion in yearly sales though. If you care to read up on cholesterol and overall mortality there is an introductory write-up here
