The Food and Drug Administration (FDA) today issued a public health advisory concerning the identified risks and benefits of Crestor (Rosuvastatin calcium), a cholesterol-lowering drug.
The Crestor advisory is intended to notify the public of "potentially significant emerging safety data," says Dr. Steven Galson, Acting Director, Center for Drug Evaluation and Research (CDER).
Risk of Serious Muscle Damage
The FDA is updating information about the risk of rhabdomyolysis (serious muscle damage) in patients taking Crestor, as well as other statin drugs.
This is a well-known, rare adverse effect of all statins, the agency notes. Extensive review of the large amount of data available to date from controlled trials, as well as the latest post-marketing safety information, indicates that patients taking recommended doses of Crestor have a similar risk of rhabdomyolysis as patients on other statin cholesterol treatments.
Crestor's manufacturer, Astra-Zeneca Pharmaceuticals, today revised the package insert for Crestor, based on discussions with the FDA.
These changes re-emphasize recommendations made in the original label about the need for physicians to consider using lower starting doses of the drug in some individuals as a means of reducing the risk of rhabdomyolysis, according to the FDA.
The revised labeling notes that this may be particularly important for treating Asian American patients, since clinical trial data suggest that they (along with patients on cyclosporine or patients with severe renal insufficiency) may have higher drug levels and therefore be at greater risk for muscle injury due to Crestor than the general population.
Kidney Failure Risk
Kidney failure of various types also has been reported in patients treated with Crestor, as well as other statins.
However, patients who are candidates for statin therapy (e.g., patients with diabetes, hypertension, atherosclerosis, and/or heart failure) also may be at higher risk for kidney failure even when they are not prescribed statin therapy. Based on FDA's review of these cases and the available data from controlled trials, FDA cannot confirm that recommended doses of statins, including Crestor, can cause or worsen kidney failure.
Overall, FDA says it believes that potential benefits of statin drugs (including Crestor) when used as labeled and indicated for the treatment of elevated cholesterol (hypercholesterolemia) outweigh their potential risks and provide an important treatment option for millions of Americans at risk of heart disease.

Anyone who is harmed by *any* medication will face difficult challenges. Fortunately, even with this news, serious side effects from statins are extremely low. The odds of a serious bleed from aspirin are much higher.

I live with someone disabled for 7 years by Lipitor.
I have two friends who have lost their homes this calendar year due to statin damage disabling them to the point that they were unable to work. Two others this calendar year who are in the process of determining the degree of statin cognitive damage they have suffered (both had NP tests and scored below the 10 percentile), one in the process of losing his job at 52 years of age due to the statin damage.
How many people are you acquainted with who have lost all income due to aspirin bleed?
How many people do you know who have lost their homes because of aspirin bleed?
Statin damage to muscles, nerves, and brain function causes lasting disability that is not comparable to aspirin bleed.

Au contraire, Mrs. Hope.
Aspirin:
Damage to the lining of your stomach, prolonged bleeding time, wheezing, breathlessness, ringing in the ears, hearing loss, chronic catarrh & runny nose, headache, confusion, nausea, vomiting, GI upset, GI bleeding, ulcers, rash, allergic reactions, hives, bruising, abnormal liver function tests, liver damage, and hepatitis. Kidney Damage, severe metabolic derangements, respiratory and central nervous system effects, strokes, fatal hemorrhages of the brain, spleen, liver, intestines & lungs and DEATH.
300 to 500 reported deaths per year: (taken as directed).
[BTW Sharon, death is a serious disabling side effect.]
Ulcers caused by NSAIDs, including aspirin kill about 16,500 people in the United States each year (reported in the New England Journal of Medicine).
Can you lose your home when you're dead? Can you work when you're dead? Can you have cognitive damage tests when you're dead? Can you lose your job when your dead? Can you lose your income when you're dead? Can you have a lasting diability when you're dead?
Your personal and touching story has no bearing on the fact that aspirin debilitates and kills more people yearly than statins.
NOTE: The benefits of aspirin for cardiovascular and cerebrovascular indications has been shown in many studies. I am not against the use of aspirin. The risks of any medication need to be weighed with the benefits.

Bullfeathers! It's been known for some time that the incidence of kidney failure is a whopping 75x higher compared to other statins.
Just a casual observation: When drugs appear on this _Do Not Use_ list, about 24 to 30 mos later, the FDA finally bans them.

The categories and winners of the Bitter Pill Awards for Exposing Drug Company Manipulation of Consumers are:
Performance Anxiety Award: For Exploitation of Male Fears of Inadequacy. A three-way tie, going to the makers of Viagra, Levitra and Cialis
What ads for these drugs have in common is they all play on male fears of impotence, and by association, with masculinity and virility. No longer do they seem to focus on Erectile Dysfunction as a medical condition, but instead on sexual desire, potency and "mischievousness." These ads help demonstrate the misplaced priorities of the drug industry as a whole.
Speak No Evil Award: For Concealing Drug Risks and Benefits in the Name of Profits:
Shared by Merck, maker of Vioxx, and Pfizer, maker of Celebrex By now the dangers associated with Vioxx and Celebrex are well known. What is less well known is that Merck and Pfizer knew about the dangers during their aggressive direct to consumer ad campaigns and chose to hide them from the public. Merck used tactics such as a sales staff training manuals with the title "Dodgeball Vioxx" which instructed representatives how to evade doctors' questions about the cardiovascular safety of Vioxx. The marketing campaigns for these two drugs led millions of people who would have done just as well on a much cheaper over the counter drug to pay top dollar for a drug that potentially put them at great risk.

Meanwhile I do not believe pharmaceutical folks have anything like a Hippocratic Oath. Too bad since they seem to running the heath care business. Seems their restraints are legal in nature and ethics a dream state.
Ethos and common sense must arise and they can and do usually when it is very obviously needed. Meanwhile suffering rules the day.

Public Citizen Press Releases
Providing the latest information about Public Citizen activities

FDA Shows Dangerous Cowardice in Crestor Announcement
Statement of Sidney M. Wolfe, MD, Director, Public Citizen's Health Research Group
Today's announcement by the U.S. Food and Drug Administration (FDA)
concerning revised labeling of the cholesterol-lowering drug Crestor is
yet another example of the agency's dangerous cowardice in failing to
adequately protect people in this country from uniquely dangerous
prescription drugs. Like statements from AstraZeneca, the FDA's
statement is replete with false and misleading information. Rather than
responding in a public health-positive manner to our March 2004 petition
and banning this drug, the FDA has done exactly what AstraZeneca wanted
with minimal labeling changes and surely has pleased one of the drug
companies contributing to the $150 million in drug industry funding that
the FDA is receiving this year for drug review.
Since the last supplement to our petition to ban Crestor (submitted in
October 2004), which was based on adverse reaction reports through
August 26 of last year, there have been an additional 52 U.S. cases of
life-threatening muscle damage (rhabdomyolysis) reported to the FDA and
an additional 12 U.S. cases of kidney failure or impairment in people
not having rhabdomyolysis reported to the agency up to the end of
January of this year. The total of such U.S. cases reported since the
drug was first marketed in September 2003 is now 117 cases of
rhabdomyolysis and 41 cases of kidney failure, both higher than seen
with the other currently marketed statins. Because of concerns about the
safety of Crestor, several countries, including Germany, Norway and
Spain, have not approved the drug.
Although the increased rate of rhabdomyolysis is not as high as that of
the now-banned Baycol, the FDA is well aware that the rate is higher
than that of the other statins, a fact it covers up by saying the rate
is "similar." The FDA statement also includes other "facts" that
are extremely misleading if not false:
FDA Statement: "Data available to date from controlled trials, as
well as post-marketing safety information, indicate that the risk of
serious muscle damage is similar with Crestor compared to other marketed
statins."
Response: Crestor was the only statin that caused rhabdomyolysis at any
dose in clinical trials prior to approval. (The cases occurred at 80 mg,
a dosage not approved, but most of the post-marketing cases are
occurring at 10 or 20 mg.)
FDA Statement: "Mild, transient proteinuria (or protein in the urine,
usually from the tubules), with and without microscopic hematuria
(minute amounts of blood in the urine), occurred with Crestor, as it has
with other statins, in Crestor's pre-approval trials."
Response: Although the FDA admits that with Crestor, "The frequency
of occurrence of proteinuria appeared dose-related," it fails to
mention that this dose-related increase in proteinuria and hematuria
(blood in the urine) was seen only with Crestor and not with any other
statin.
FDA Statement: "In clinical trials with doses from 5 to 40 mg daily,
this effect was not associated with renal impairment or renal failure
(i.e., damage to the kidneys)."
Response: (from FDA medical officer during the July 2003 FDA hearing on
Crestor approval): "These three cases of renal insufficiency of
unknown etiology are of concern because they present with a clinical
pattern, which is similar to the renal disease seen with rosuvastatin in
these clinical trials. ... Proteinuria and hematuria could be potentially
managed with regular urinalysis screening. However, if they are the
signals for the potential progression to renal failure in a small number
of patients, this may represent an unacceptable risk since currently
approved statins do not have similar renal effects." (emphasis
added)
Rather than being a "Public Health Advisory," as the announcement
is titled, this FDA statement is more like an AstraZeneca Health
Advisory. In its inability to serve two masters, the FDA has sided once
again with its funders in the drug industry.

Sharon Hope - 05 Mar 2005 19:02 GMT Likely your relative also suffered nerve damage. Neuromuscular damage by statins is part of why it is so disabling, as the nerve damage takes much longer to heal, and some is possibly permanent.
Your relative might benefit from a neurologist consultation, particularly if the neurologist is familiar with the neurotoxic effects of statins.
