There is only a ripple of suspicion on the AD & cholesterol lowering
drugs theory..  It may go the way of  so many other theories

I, for one, chose  not to take Crestor,Lipitor or the like when offered
it  a few months ago..

My husband has been on these things forever or so it seems..I can't
believe a cardiac consultant, in Texas, only last month wanted to do a
thallium stress test on him AND perhaps put in another stent..
It's difficult at times to give civil responses to Drs..

Nope.<not smiling or lol> but  could tolerate a few  good jokes about
now..

My husband, Don, finds laughter in everything.-- poor fella,--- laughing
,clapping, talking but can't finish a thought..   enough of this!!!

Vastin is Fluvastatin, which is also known under the brand name Lescol.
Other statins include Lipitor, Crestor, Zocor, Pravachol, Mevacor, and
Baycol.

Cholesterol-lowering Statin drugs are the #1 most prescribed class of all
drugs at this time, and Lipitor is the most prescribed of all drugs.

Credible evidence of statin drugs destroying memory? Absolutely.  The statin
adverse effects include Amnesia and Short-term memory loss, as well as
cognitive damage and aphasia.

A description of my husband's symptoms, along with others', was published by
Smart Money Magazine in an article entitled, "The Lipitor Dilemma" - reprint

Simvastatin-Associated Memory Loss

Amanda Orsi, Pharm.D., Olga Sherman, Pharm.D., and Zegga Woldeselassie,
Pharm.D.,

Abstract: The statins are widely used to treat dyslipidemias. They are
generally associated with mild adverse effects, but rarely, more serious
reactions may occur. A 51-year-old man experienced delayed-onset,
progressive memory loss while receiving simvastatin for
hypercholesterolemia. His therapy was switched to pravastatin, and memory
loss resolved gradually over the next month, with no recurrence of the
adverse effect.

Excerpt:

Do HMG-CoA reductase inhibitors impair memory? After taking simvastatin for
a year, a 51-year-old patient developed short term memory loss, to the
extent of being unable to complete his sentences because he would forget
what he was going to say. The drug was discontinued, replaced by
pravastatin, and within one month his memory returned.14 In a separate case,
a 67-year-old woman developed impaired short-term memory, altered mood,
social impairment, cognitive impairment and dementia after one year of
atorvastatin therapy. When atorvastatin was discontinued, her memory, mood
and cognition improved completely.15 Memory impairment in a patient
receiving atorvastatin has been reported to the BC Regional ADR Centre.

Finally, on memory loss and statins: Sworn testimony from the Baycol trial
in Corpus Christi, Texas. From the transcript of the AM Session on 03-05-03,
in the case Hollis Haltom Vs. Bayer Corporation. Testifying under oath,., in
response to the plaintiff's attorney's question, "What is your current
position at Bayer?", LAWRENCE POSNER, M.D of BAYER stated: "I'm the --  
currently I'm the head of worldwide regulatory affairs for our prescription
drug business, which means I have responsibility in somewhere between 60 and
100 countries where we sell products for registrations, compliance, things
of that nature." Excerpts from the trial transcript follow, with the Q
indicating counsel's Question, and the A indicating Dr. Posner's Answer:

Q. So there are some concerns addressed here back in 1995 about testing up
to .8. And do you know what the nature of the concern was?

A. Yes. It was related to a side effect that occurred in the brain.

Q. Of what kind of animal?

A. It occurred in the brain of dogs.

Q. Okay. So there was a side effect that occurred in dogs, and then there
was a concern about whether you wanted to go forward and test at this higher
dose level in human beings, given what you had learned about the dogs,
right?

A. That's correct.

Q. Okay. Now, did you just say, well, let's forget about these concerns and
we'll go ahead and put .8 on the market anyway, or did you do some further
analysis that was not mentioned the other day?

A. Yes. The authors of this had -- they had two concerns. One concern was
the toxicity that they found in the brain of dogs. But the other was that
they had no way to identify this and who might be at risk before it
happened. So there was no way to detect that someone was at risk for this
side effect.

[skip some testimony on other topics]

Q. Do you remember in one kind of animal there had been some studies done
that there could be a particular kind of problem with one kind of animal?

A. Oh, yeah. Yes, from the -- that's correct, from the toxicology studies.

Q. Okay. And were you able to demonstrate to your own satisfaction, to
SmithKline's satisfaction, to the FDA's satisfaction, that that particular
problem that showed up with that kind of animal is not something that
happens in human beings?

A. Yes. We did it -- we did it by explaining the toxicology data. We also
explained it on the basis of kinetic data. That actually at the higher
levels of drug, what happens is a certain amount of drug is bound to
proteins in the body that circulate; and therefore, is not -- cannot cause
side effects. And actually, a much smaller proportion of the drug is free.
And that what you corrected for that, you actually found out that the
margins of safety were in fact greater than you would predict just from the
animal data.

Q. And as you move forward then and got approval and sold Baycol from 1997
through 2001, did that problem that had shown up with that one kind of
animal ever become a problem with human beings?

A. It was actually shown with other statins as well. It wasn't unique to
cerivastatin. It was a problem -- it was identified early on with lovastatin
and some of the others. In fact, for none of the statins did it ever predict
for any clinical problem or toxicity.

Q. So these animals would have that same problem regardless of which
statin -- or at least with other statins?

A. Certainly with lovastatin it was true.

Q. But when it came time to human beings, that just wasn't something that
happened to human beings?

A. And I think today no one pays much attention to it.

"Based on epidemiologic studies as well as case reports, a risk of
peripheral neuropathy associated with statin use may exist; however, the
risk appears to be minimal. On the other hand, the benefits of statins are
firmly established. These findings should alert prescribers to a potential
risk of peripheral neuropathy in patients receiving any of the statins; that
is, statins should be considered the cause of peripheral neuropathy when
other etiologies have been excluded."

initiation of simvastatin, in a 58-year-old man, who had experienced a
similar but milder episode after starting pravastatin 6 months earlier. This
case suggests that acute polyradiculoneuropathy may represent a rare but
serious side-effect of statin treatment. It also raises the issue of the
pathophysiology of acute neuropathy on statin exposure, with a
hypersensitivity reaction resulting in an immune-mediated process being
possible instead of the hypothesized mitochondrial dysfunction in chronic
cases."

prescutation of asymmetrical numbness and weakness. More common causes of
mononeuropathy multiplex were excluded and the patient improved after the

From the abstract: "The authors verified a diagnosis of idiopathic
polyneuropathy in 166 cases. The cases were classified as definite (35),
probable (54), or possible (77). The odds ratio linking idiopathic
polyneuropathy with statin use was 3.7 (95% CI 1.8 to 7.6) for all cases and
14.2 (5.3 to 38.0) for definite cases. The corresponding odds ratios in
current users were 4.6 (2.1 to 10.0) for all cases and 16.1 (5.7 to 45.4)
for definite cases. For patients treated with statins for 2 or more years
the odds ratio of definite idiopathic polyneuropathy was 26.4 (7.8 to 45.4).
CONCLUSIONS: Long-term exposure to statins may substantially increase the
risk of polyneuropathy."

Peripheral Neuropathy and Lipid-Lowering Therapy

Paul E. Ziajka, MD, PhD, and Tammy Wehmeier, RN, Orlando, Fla.

Abstract: We report a case of peripheral neuropathy induced and excerbated
by several commonly used HMG-CoA reductase inhibitors including lovastatin,
simvastatin, pravastatin, and atorvastatin, and the vitamin niacin. A review
of the literature shows similar cases with individual lipid-lowering drugs,
but this case shows the cross-reactivity of the neuropathic process to
different HMG-CoA reductase inhibitors, and is the first reported case of a
peripheral neuropathy exacerbated by the use of niacin.

Dr. Phillips study mentioned in a Wall Street Journal article (This is
smooth muscle, not cardiac muscle.) Conclusion "statin therapy may be
associated with increased oxidation injury.mild adverse effects of statins
that are difficult to assess might be much more prevalent than widely
considered "

DEFINITION Ubiquinone biosynthesis - Reference pathway. Diagram of the
Ubiquinone (aka CoQ10) metabolic pathway, highlighting exactly where the
Statins interrupt it. All of the 17 or so steps have to happen correctly for
the body to produce CoQ10, but statins interrupt (or retard) this in step
#2.

Introduction to the Citizen's petition to the FDA:

Peter Langsjoen This is the introduction to the petition. (It is aimed at
getting attention, and the wording may be more alarming than necessary.)

To the FDA: "Citizen Petition To Change The Labeling For All Statin Drugs

"This study evaluated left ventricular diastolic function with Doppler
echocardiography before and after statin therapy. Statin therapy worsened
diastolic parameters in most patients; coenzyme Q(10) supplementation in
patients with worsening diastolic function with statin therapy improved
parameters of diastolic function."
