May 24, 2005 Cholesterol Drug Crestor Poses Risks, Journal Says Study Suggests Use Only as Last Resort By Marc Kaufman Washington Post Staff Writer
The powerful cholesterol-lowering drug Crestor is significantly more likely than other statins to cause muscle deterioration that can lead to kidney disease and failure, according to a study in the American Heart Association's journal, Circulation.
The conclusion is at odds with the most recent recommendation of the Food and Drug Administration, which in March rejected a citizen's petition to remove Crestor from the market. At the time, the FDA said Crestor, which has been aggressively marketed by AstraZeneca LP, appeared to be no more dangerous than other statins for most people.
Based on the number of side effects reported to the FDA, however, the researchers said yesterday that Crestor was two to six times as likely to cause complications over a one-year period as three other statins on the market.
Although the number of serious side effects reported by Crestor users was small, the study authors said the higher rate convinced them that doctors should try their patients on other statins and only turn to Crestor as a last resort.
The study "raises concerns about the safety of this drug at the range of doses used in common clinical practice," the study concludes. "It would seem prudent at the current time for health care providers to consider other statins as first-line therapy."
AstraZeneca defended its billion-dollar-a-year drug, saying "we strongly disagree with the conclusions of this study." In a statement, the company said the FDA's voluntary system for soliciting reports of complications, called "adverse events," does not confirm the accuracy of the accounts it gets and so cannot be used to determine a drug's risks.
The company cited the FDA's recent conclusion that based on all the evidence available, Crestor does not pose an unacceptable risk. "AstraZeneca again reaffirms that the safety profile of Crestor is in line with other marketed statins, and is a highly effective cholesterol-lowering therapy," it said.
With drug safety an increasingly hot topic with the public, doctors and members of Congress, the Circulation paper quickly became a new source of controversy.
Sidney M. Wolfe of Public Citizen Health Research Group, who filed the petition rejected by the FDA, said the study confirmed his conclusions.
"This should be very embarrassing to the FDA," Wolfe said. He said that unlike the arthritis painkillers Vioxx and Bextra, which were recently taken off the market because of harmful side effects, Crestor's potential to cause muscle and kidney damage was known before the drug was approved.
"Short of having the drug taken off the market, I don't think that anything could contribute to the end of a drug more than this paper," Wolfe said.
Scott M. Grundy, a University of Texas Southwestern Medical Center researcher long associated with efforts to reduce cholesterol levels to prevent heart disease, defended the drug. Grundy, in a commentary accompanying the research paper, said he was not convinced that the risks from the higher potency of Crestor outweighed its possible benefits to patients with especially high cholesterol levels.
The American Heart Association -- which did not take a position on either the study or the accompanying commentary -- held a teleconference yesterday to discuss the study and its view that patients should continue on whatever statins their doctors prescribe. Grundy said he would prescribe Crestor now as readily as any other statin. But Richard H. Karas of Tufts-New England Medical Center, lead author of the Circulation paper, said he would recommend Crestor only as a last resort.
Both Karas and Grundy have received research contracts and speaking fees from statin makers, including AstraZeneca. The heart association also receives considerable financial support from drug companies.
Crestor, which was approved by the FDA in 2003, is agreed to be the most potent statin on the market. Its higher strength, however, does not make a dramatic difference in studies. While statins such as Lipitor, Zocor and Pravachol lower LDL -- or harmful -- cholesterol by 50 to 55 percent, Crestor decreases it by 55 to 60 percent, said Grundy and Karas.
In the new study, doctors of patients taking Crestor were significantly more likely to report complications of kidney disease and rhabdomylosis, a muscle deterioration that releases toxins into the blood that can cause renal failure. The overall number was small -- 145 muscle or kidney problems out of 5.2 million prescriptions during the drug's first year on the market -- but the number was substantially higher than for other statins.
In 2001, the FDA took Baycol, a considerably more powerful statin than Crestor, off the market because of similar side effects. In a congressional hearing last December, FDA drug safety officer and whistle-blower David Graham identified Crestor as one of five drugs now on the market that he believed posed serious safety problems that were not balanced by their benefits.
The FDA yesterday referred callers to its March conclusions that Crestor is no more hazardous than other statins.
Grumpy Richard - 24 May 2005 15:05 GMT Incredible, but typical.
Can anyone explain why ANY physician would prescribe this stuff, given its troubled history, and the availability of other statins that have much better track records?

One reason may be that the patient did not respond well to the other statins.
Grumpy richard - 24 May 2005 16:58 GMT Could be, but I suspect that the numbers ($1 billion of the stuff sold last year) tend to point to other motives.
I found this very interesting newsletter from 2003, discussing the introduction of Crestor:
http://www.trends-in-medicine.com/Aug2003/Crestor083p.pdf
A terrifying quote from the newsletter: "Six of the 10 cardiologists interviewed plan to use Crestor as soon as it is available, and they will use it much as they would any other statin."
Are these just six particularly stupid and reckless cardiologists? Or are they representative of the entire profession?

Grumpy Richard - 25 May 2005 03:35 GMT Call me an old fuddy-duddy, but it seems wrong and strange to me that millions of people were placed on a drug that's not particularly more effective than others at lowering *indicators* of trouble, has not been shown to actually reduce true morbidity and mortality, and may have significant side effects.
Heck, the stuff might actually confer immortality - but until its been very-well characterized, which it clearly isn't yet, why not try to stick to things that *are* very-well characterized, and proven to be safe and effective?

Can Garlic Reduce Levels of Serum Lipids? A Controlled Clinical StudyJain, Adesh K. MD; Vargas, Ramon MD; Gotzkowsky, Sandra RN; and McMahon F. Gilbert, MD, FACP, "Can Garlic Reduce Levels of Serum Lipids? A Controlled Clinical Study", American Journal of Medicine, June 1, 1993, Vol. 94, Num. 0, pp. 632-635
"Forty-two healthy adults (19 men, 23 women), mean age of 52 +/- 12 years, with a serum cholesterol (TC) level of greater than or equal to 220 mg/dL received, in a randomized, double-blind fashion, either 300 mg three times a day of standardized garlic powder in tablet form or placebo ... The base serum TC level of 262 +/- 34 mg/dL was reduced to 247 +/- 40 mg/dL (p<0.01) after 12 weeks of standardized garlic treatment. Corresponding values for placebo were 276 +/- 34 mg/dL before and 274 +/- 29 mg/dL after placebo treatment. Low-density lipoprotein cholesterol (LDL-C) was reduced by 11% by garlic treatment and 3% by placebo (p<0.05). ... Treatment with standardized garlic 900 mg/d produced a significantly greater reduction in serum TC and LDL-C than placebo. The garlic formulation was well tolerated without any odor problems."
Inhibition of Low Density Lipoprotein Synthesis by Dietary Omega-3 Fatty Acids in HumansIllingworth, Roger D.; Harris, William S.; and Connor, William E., "Inhibition of Low Density Lipoprotein Synthesis by Dietary Omega-3 Fatty Acids in Humans", Arteriosclerosis, May 1, 1984, Vol. 4, Num. 3, pp. 270-275
"Diets rich in omega-3 fatty acids derived from fish oils lower the plasma concentrations of low density lipoproteins (LDL) and very low density lipoproteins in humans. ... We conclude that dietary omega-3 fatty acids lower plasma LDL levels in normal human subjects by reducing the rate of synthesis of apoprotein B."
"Recent metabolic studies have indicated that when fish oils rich in omega-3 fatty acids are added to the diets of either normal volunteers or hyperlipidemic patients, the plasma concentrations of both cholesterol and triglycerides are reduced. We have previously shown that dietary fish oils lower plasma concentrations of very low density lipoprotein (VLDL) and low density lipoprotein (LDL) cholesterol levels even more effectively than equal amounts of polyunsaturated vegetable oils. The purpose of the experiments reported in this paper was to examine the mechanism(s) by which dietary omega-3 fatty acids reduce plasma concentrations of LDL in normal human subjects."
"Steady-state concentrations of plasma cholesterol and triglycerides on the control and fish-oil-enriched diets were obtained in 10 to 14 days and both were significantly lower on the omega-3 fatty acid-enriched diet. The total and LDL cholesterol concentrations fell 23% and 20% respectively, on the fish-oil-enriched diet; these changes were paralleled by a 43% decrease in the concentrations of plasma triglycerides."
Beneficial Effects of Soybean Isoflavone in Postmenopausal Japanese Women: A Four-Week StudyUesugi, Takehiko; Fukui; Yukata, MS; and Yamori, Yukio, MD, PhD, "Beneficial Effects of Soybean Isoflavone in Postmenopausal Japanese Women: A Four-Week Study", Journal of the American College of Nutrition, January 1, 2002, Vol. 21, Num. 2, pp. 97-102
"In addition to beneficial effects on bone metabolism, isoflavones lowered total serum cholesterol levels as well as LDL cholesterol. High LDL cholesterol levels are known to be associated with atherosclerosis. Estrogen increases LDL catabolism by increasing the number of LDL receptors, as shown in hepatocytes from estrogen-treated rats. Isoflavones may reduce LDL level by increasing the number of LDL receptors in a similar manner. Our data thus confirmed that isoflavones had beneficial effects on bone and lipid metabolism, suggesting they may be useful for preventing both osteoporosis and coronary heart diseases."

"Enstrom et al showed a risk reduction in cardiovascular disease of 42% in men and 25% in women consuming > 50 mg vitamin C/d from the diet plus regular supplements, corresponding to approximately 300 mg total vitamin C/d. An earlier study b Enstrom et al indicated that intakes of vitamin C > 250 mg/d were not associated with an additional risk reduction for cardiovascular disease, although subsequent reanalysis of the data indicated that intakes > 750 mg/d were associated with a reduction in overall mortality. Sahyoun et al reported a significant 62% lower risk of cardiovascular disease in a population of elderly men and women consuming > 388 mg vitamin C/d than in those consuming < 90 mg/d."
Cross sectional study of effects of drinking green tea on cardiovascular and liver diseasesImai, K. and Nakachi, K., "Cross sectional study of effects of drinking green tea on cardiovascular and liver diseases", BMJ (British Medical Journal), March 18, 1995, Vol. 310, Num. 0, pp. 693-696
"Our cross sectional study showed a close association between high consumption of green tea and normalization of serum components, which reflects cardiovascular and liver diseases. Increased consumption of green tea, especially more than 10 cups a day, was associated with a decreased serum total cholesterol and triglycerides concentrations; increased high density lipoprotein cholesterol concentrations and decreased low density and very low density lipoprotein cholesterol concentrations, resulting in a reduced atherogenic index; decreased serum concentrations of lipid peroxides among smokers; and decreased aspartate aminotransferase and alanine aminotransferase concentrations, and serum ferritin concentrations. The associations between green tea and serum total cholesterol and triglycerides concentrations and between green tea and high and low density lipoprotein cholesterol concentrations are well correlated with experimental observations and the prevalence of heart disease in our cohort, implying green tea may act preventively against cardiovascular disease."
Antioxidant Supplementation in Atherosclerosis Prevention (ASAP) study: a randomized trial of the effect of vitamin E and C on 3-year progression of carotid atherosclerosisJ.T. Salonen; K. Nyyssönen, R. Salonen; H.-M. Lakka, J. Kaikkonen; E. Porkkala-Sarathaho; S. Voutilainen; T. A. Lakka; T. Rissanen; L. Leskinen; T.-P. Tuomainen; V.-P. Valkonen; U. Ristonmaa; and H.E. Poulsen, "Antioxidant Supplementation in Atherosclerosis Prevention (ASAP) study: a randomized trial of the effect of vitamin E and C on 3-year progression of carotid atherosclerosis", Journal of Internal Medicine, January 1, 2000, Vol. 248, Num. 0, pp. 377-386
"In men, the proportion of those who experienced progression was reduced by 74% (95% CI 36-89%, P = 0.003) in the group randomized to receive both vitamins, as compared with those who received only placebo. The respective treatment effect was nonsignificant in groups that received only vitamin E or vitamin C, although there were trends towards protection."
"The present findings are the first demonstration in a population-based study of an atherosclerotic disease preventing effect of supplementation with antioxidant vitamins. Our study suggests that the benefit may be limited to men, and possibly to men who are at increased oxidative stress such as smokers or those who have insufficient status of dietary or endogenous antioxidants. The observed effect modification by gender and smoking status needs to be retested in further clinical trials."
"The progression rate in smoking men who received vitamin E and C supplements was lower than in nonsmoking men receiving placebo. Thus, in this study the preventive effect of the supplementation was at least equal to the atherosclerosis promoting effect of smoking. This is not a trivial effect from the public health point of view."
"The vitamins E and C supplements were safe. There were neither excess death nor excess other adverse events in the groups randomized to supplements, although the sample size was not designed to detect effects on either deaths or other disease events. Both the adherence to treatment and the bioavailability of the supplements were good, judged based on increases of plasma vitamin levels. The drop-out rate during the trial was exceptionally low."
"In conclusion, our study shows that a formulation providing combined supplementation with reasonable doses of both vitamin E and slow-release vitamin C for at least three years can retard the progression of common carotid atherosclerosis substantially in regular smoking men. However, this study does not provide evidence for any substantial preventive effect in postmenopausal women, although a small benefit cannot be ruled out. As common carotid plaques and increased intimal-media thickness have been shown to predict coronary events, this observation may imply benefits with regard to atherosclerosis-related events."
Study: Diet lowers cholesterol as well as drug", CNN, February 8, 2005
A diet rich in fiber and vegetables lowered cholesterol just as much as taking a statin drug, Canadian researchers reported Monday.
They said people who cannot tolerate the statin drugs because of side-effects can turn to the diet, which they said their volunteers could easily follow.
David Jenkins of St. Michael's Hospital and the University of Toronto and colleagues created what they called a diet "portfolio" high in soy protein, almonds, and cereal fiber as well as plant sterols -- tree-based compounds used in cholesterol-lowering margarines, salad dressing and other products.
They tested their diet on 34 overweight men and women, comparing it with a low-fat diet and with a normal diet plus a generic statin drug, lovastatin.
Each volunteer followed each regimen for a month, with a break in between each treatment cycle.
Writing in the American Journal of Clinical Nutrition, Jenkins and colleagues said the low-fat diet lowered LDL -- the low-density lipoprotein or "bad" cholesterol -- by 8.5 percent after a month. Statins lowered LDL by 33 percent and the "portfolio" diet lowered LDL by nearly 30 percent.
4 Reasons to Grab a Handful of Almonds as Your Next Snack", Medical News Today, February 7, 2005
During American Heart Month, a New Study Adds to the Body of Research on Almonds' Healthy Heart and Weight Benefits -
Crunchy, handy almonds have been sighted in many new breakfast, snack, and salad products as research continues to show their healthful qualities. So, when you're perusing the supermarket aisles during American Heart Month (February) or National Nutrition Month (March), consider these three reasons almonds fit the bill as a perfect nutritional "boost" to meals and snacks:
1) New research supports almonds' ability to lower cholesterol. A study to be published Monday in the American Journal of Clinical Nutrition provides more evidence that almonds are one of the most heart-healthy foods around.
The study finds that when directly compared to first-generation statins, a certain heart-healthy dietary approach including almonds is just as effective in lowering LDL, or "bad," cholesterol below the recommended range for heart disease prevention.
Lifestyle Changes Cut Heart Risk Without Drugs", Reuters UK, January 5, 2005
In a new study, a 12-week program designed to change unhealthy lifestyles helped adults with high blood pressure, high cholesterol, and high blood sugar reach their goal risk-factor levels without using drug therapy.
These results "refute the notion that intensive lifestyle intervention is not worth the effort," lead author Dr. Neil F. Gordon, from St. Joseph's/Candler Health System in Savannah, Georgia, and colleagues note in the American Journal of Cardiology.
The results are based on a study of 2390 adults who participated in the lifestyle program, which involved an initial health assessment followed by the setting of goals and lifestyle changes designed to reduce their risk factors.
Participation in the program was associated with a significant improvement in blood pressure, cholesterol levels, sugar levels, and body weight. Moreover, in a subset of 700 patients, the intervention was linked to a significant reduction in standard risk scores for heart disease.
"Therapeutic lifestyle changes can generally be implemented less expensively than most medications and, unlike single-drug therapy, favorably affect multiple risk factors," the investigators point out.
Thus, the current findings could have important implications for healthcare payers, which often do not reimburse for such lifestyle interventions, they add.

Valerie Reitman, "Eating cinnamon boon to health, study finds", Cincinnati Post, January 5, 2005
A little bit of cinnamon might spice up your health.
The aromatic bark can lower blood sugar, triglycerides and cholesterol levels, as well as improve insulin functioning, particularly in Type 2 diabetics, researchers have found. Richard Anderson, lead scientist at the Human Nutrition Research Center in Beltsville, Md., has been studying cinnamon and calls its medicinal properties the most significant nutritional discovery he's seen in 25 years.
"I don't know of anything else," he said, other than drugs, "that can change glucose, triglycerides and cholesterol levels nearly so much."
The most recent study, which appeared in the journal "Diabetes Care," showed that, after 40 days, 30 diabetics who had taken 1 to 6 grams of cinnamon extract daily reduced their risk factors for cardiovascular disease. Specifically, their mean fasting glucose fell 18 percent to 29 percent, their triglycerides 25 percent to 30 percent, their LDL ("bad") cholesterol 7 percent to 27 percent and their total cholesterol 12 percent to 26 percent.
Good fats lower multiple heart disease risk factors", Medical News Today, November 9, 2004
A Penn State study has shown that a diet rich in alpha-linolenic acid from walnuts, walnut oil and flaxseed oil not only lowered bad cholesterol but also decreased markers for blood vessel inflammation in men and women representative of typical Americans at cardiovascular risk.
While previous studies have shown that walnut supplementation favorably affects cholesterol and other lipids that are signs of cardiovascular risk, this new study is the first to demonstrate that a diet high in walnuts decreases C-reactive protein (CRP), a marker of inflammation strongly associated with heart disease.
Dr. Penny Kris-Etherton, distinguished professor of nutrition who led the study. says, "In a heart healthy diet, you need different unsaturated fatty acids that come from a variety of vegetable sources. Walnuts are a good source of two essential unsaturated fatty acids, alpha-linolenic acid and linoleic acid. They are a source of dietary fiber and a small amount of plant protein and other important vitamins and minerals. This research shows that walnuts, with their unique nutrient profile, can play a role in reducing cardiovascular risk factors as part of eating plans that also control saturated fat, trans fat, dietary cholesterol and calories."
The study is detailed in a paper, Dietary Alpha-Linolenic Acid Reduces Inflammatory and Lipid Cardiovascular Risk Factor in Hypercholesterolemic Men and Women, in the current issue of the Journal of Nutrition. The authors are Guixiang Zhao, former doctoral student in nutritional sciences at Penn State; Dr. Terry D. Etherton, distinguished professor and head of the Department of Dairy and Animal Sciences; Dr. Keith R. Martin, assistant professor of nutritional sciences; Dr. Sheila G. West, assistant professor of biobehavioral health; Dr. Peter J. Gillies, director, Health Science Strategy, DuPont Haskell Laboratory for Health and Environmental Sciences, DuPont; and Kris-Etherton.
The study included 20 men and 3 women, average age about 50, who were overweight, had moderately elevated cholesterol and LDL cholesterol and were representative of individuals at risk for cardiovascular disease. On average their total cholesterol was 225, LDL cholesterol 154, HDL cholesterol 45 and triglycerides 137 mg/dl.
The participants ate three experimental diets that provided about 35 percent of total calories as fat. One diet approximated the average American diet (AAD). Another, the linoleic acid (LA) diet, included an ounce of walnuts and a tablespoon of walnut oil that provided about 12.6 percent of calories from linoleic acid and 3.6 percent of calories from alpha-linolenic acid. The third, the alpha-linolenic acid (ALA) diet, included the walnuts and walnut oil as well as a teaspoon of flaxseed oil to boost the content of alpha-linolenic acid. The fat content was 10.5 percent of calories from linoleic acid and 6.5 percent from alpha-linolenic acid.
The participants consumed each diet for six weeks. Then they took a two-week break before beginning the next diet. At the end of each 6-week diet period, they provided blood samples so that their cardiovascular risk factors could be monitored.
Compared to the average American diet, both the LA and the ALA diets lowered total cholesterol about 11 percent, LDLs about 11 or 12 percent and triglycerides about 18 percent. After six weeks on the diet, CRP declined after both the LA and ALA diets but more so on the ALA diet. Some participants had a dramatic reduction in CRP.
Amy Norton, "Exercise During Pregnancy Keeps Cholesterol Down", Reuters UK, August 27, 2004
Women who stay active early in pregnancy may have lower cholesterol than those who take it easy, new research suggests.
Investigators found that among 925 pregnant women evaluated at the end of the first trimester, levels of total cholesterol and blood fats called triglycerides declined as exercise levels increased.
It is normal for a woman's cholesterol and triglycerides to go up during pregnancy, lead study author Carole L. Butler told Reuters Health, but particularly large increases have been linked to the pregnancy complications gestational diabetes and preeclampsia -- a potential dangerous condition marked by high blood pressure, fluid retention and protein in the urine.
Some studies have found evidence that exercise lowers a woman's risk of both of these complications. The new findings suggest that effects on cholesterol could be one reason, said Butler, a researcher at the University of Washington in Seattle.
She and her colleagues report the findings in the American Journal of Epidemiology.
The study included women who were interviewed around their 13th week of pregnancy about their exercise habits over the previous week, as well as other lifestyle and health factors. The researchers found that women who spent the most time being active -- about 13 or more hours a week -- had the lowest total cholesterol and triglyceride levels, while sedentary women had the highest. More moderate exercisers fell somewhere in between.
Similarly, women who reported vigorous activities such as jogging had lower cholesterol and triglycerides than women who engaged in moderate exercise such as "casual" swimming and biking. Again, sedentary women had the highest levels.
However, it seems a woman need not exercise intensely to see the most cholesterol benefits. According to Butler, time spent exercising, whatever the activity, was just as strongly related to cholesterol levels as exercise intensity was.
She said the findings should encourage research into the effects of exercise later in pregnancy as well.

"Blueberries 'lower cholesterol'", BBC News, August 24, 2004
Blueberries could provide an alternative way to lower cholesterol, according to US researchers.
A compound in the fruits acted as effectively as a commercial drug used to reduce levels of the "bad" form of cholesterol in rodents.
Although the results are preliminary, the Department of Agriculture team thinks the antioxidant ingredient could be developed as a treatment.
They presented their findings to an American Chemical Society meeting.
Amy Norton, "Soy Protein May Benefit Diabetics' Kidneys", Reuters, August 6, 2004
The kidney function of people with type 2 diabetes seems to be improved by dietary soy protein, with the added benefit that their levels of "good" cholesterol also go up a bit, preliminary research suggests.
Kidney function often becomes impaired with long-standing diabetes. The study of 14 older men with diabetes-related kidney disease found that adding a soy product to their diets reduced the amount of protein in their urine -- an indicator of improved kidney function.
The study is too small to draw conclusions, but the results provide "initial evidence" that isolated soy protein may help reduce diabetics' risk of kidney and heart disease, the researchers say.
Dr. John W. Erdman Jr., one of the study's authors, told Reuters Health he hopes the work will spur larger studies.
It's unclear why soy protein might aid in diabetic kidney disease, but estrogen-like plant compounds called isoflavones could be involved, said Erdman, a professor of food science at the University of Illinois at Urbana-Champaign.
He and his colleagues there and with the Veterans Affairs Illiana Health Care System in Danville, Illinois, report the findings in the Journal of Nutrition.
For eight weeks, men in the study used an isolated soy protein powder that could be added to a drink or food. For another eight weeks, they used a milk-based protein powder.
The goal, Erdman explained, was to have the men replace part of their usual protein intake with the soy or milk protein; however, the patients failed to follow the diet instructions and instead added the protein powders to their normal routine.
Yet even with the extra protein intake, the men's excretion of protein in urine fell an average of nearly 10 percent when they consumed the soy product, the researchers found. In contrast, protein levels in the urine increased with the milk-based powder.
In addition, eight weeks on the soy powder boosted the men's levels of heart-healthy HDL cholesterol by about four percent, while it tended to dip while the men were on the milk protein.

You are right--people that take statins should also visit a health food store and buy a bottle of CoEnzyme Q10 aka CoQ10. If you have any muscle pains--some doctors prescribe a diuretic (water pill). My doctor told me that in many cases the muscle and joint pain that is caused because statins (and some blood pressure medications) in some cases cause a built up of potassium. The diuretic pills quickly flush any excess potassium and sodium out of your system because it has a chance to build up to excess levels. I realize that some medical experts disagree with the medical experts that have this point of view. I just know that my muscle pain problems related to statins went away after I started taking diurectic pills.

As to the risks you mentioned, I believe I'll take my chances. There are few ironclad solutions to many problems; there are only trade-offs. I think of it as making the best of a bad situation.

Anyway.....
ahh..as always, the voice of reason but I think Crestor's days are numbered. As these drugs get more and more potent the potential for (serious) side effects can increase. Personally, I do think better restraint is needed in prescribing them. In general, I think the whole area of statins, cholesterol and CAD are just beginning to undergo a sea change in understanding.
