Cholesterol-Lowering Statin Drugs and the Dietary Supplement Coenzyme

Q10

Worst Pills Best Pills Newsletter article June, 2005

On March 4, 2005, the Food and Drug Administration (FDA) denied two

citizen's petitions to require that the professional product

labeling, or package inserts, for the cholesterol-lowering " statin "

drugs recommend that the dietary supplement coenzyme Q10 be added to

statin therapy to reduce the risk of muscle damage, heart damage and

congestive heart failure. Coenzyme Q10 is also known as CoQ10,

ubiquinone, or ubidecarenone. It is manufactured naturally in the

bodies of humans and most mammals. While coenzyme Q10 is generally

not harmful to people, we have explained in the 2005 edition of Worst

Pills, Best Pills and online at www.worstpills.org that there have

been no studies indicating that coenzyme Q10 is clinically useful in

the treatment or prevention of anything. As we're about to explain,

that holds true regarding claims about coenzyme Q10 in the prevention

of statin toxicities.

The cholesterol-lowering statin drugs currently approved for use in

the U.S. are atorvastatin (LIPITOR), fluvastatin (LESCOL), lovastatin

(MEVACOR), pravastatin (PRAVACHOL), rosuvastatin (CRESTOR), and

simvastatin (ZOCOR).

The full text of the FDA's 21-page denial can be found on the

Internet at http://www.fda.gov/ohrms/dockets/dockets/02p0243/02p-0243-

pdn0001-vol4.pdf.

The original petition asking for the statin labeling changes was

filed in May 2002 by n Whitaker, M.D., who operates a Web site

that proclaims " Your Definitive Guide to Complementary and

Alternative Health. " The petition stated that : Dr. Whitaker

recommends the use of CoQ10 [coenzyme Q10] as a dietary supplement

and also licenses the use of his name and likeness in connection with

the manufacturing and sale of high quality dietary supplements,

including CoQ10.

Dr. Whitaker's petition can be found on the Internet at

http://www.fda.gov/ohrms/dockets/dailys/02/May02/052902/02p-0244-

cp00001-01-vol1.pdf

More than 50 references were submitted in support of the two

petitions, including laboratory data, position papers, animal

studies, and clinical investigations that proposed that statins lead

to low blood levels of coenzyme Q10, resulting in toxicity from the

statin drugs. The FDA reviewed not only the references submitted, but

also surveyed the published literature on coenzyme Q10 independently.

A study appearing in the American Heart Journal in August 2001 raises

a doubt about a proposed link between statin treatment and coenzyme

Q10 blood levels. This study found that the statins pravachol and

atorvastatin did not significantly decrease blood levels of coenzyme

Q10. The authors question the need for coenzyme Q10 supplementation.

The petitions asked the FDA to require that the labeling of all

approved statins include a boxed warning that, in part, discusses

what the petitions refer to as " risks " associated with statin-induced

deficiency of coenzyme Q10. These are impairment of heart function,

liver dysfunction, and muscle pain. In addition, the petitions

request that the FDA declare statin-induced deficiency of coenzyme

Q10 a " serious and significant concern, " and order the distribution

of Medication Guides for all approved statins. Medication Guides are

FDAapproved drug information written specifically for patients that

must be distributed with each new and refill prescription by the

pharmacist.

The petitions also state that certain " warnings " about decreased

levels of coenzyme Q10 now appear in the professional product

labeling of all statin drugs sold in Canada. This, the petitioners

contend, shows that the Canadian government has recognized the

existence of " reasonable " evidence of an association of a serious

hazard with a drug, which should put the FDA on notice and encourage

them to grant the requested warning.

In fact, Health Canada, the Canadian equivalent of FDA, does not

conclude that statin-induced decreases in coenzyme Q10 levels have

any clinical significance. For example, the Canadian simvastatin

labeling says that " Significant decreases in circulating [CoQ] levels

in patients treated with [Zocor] and other statins have been

observed. The clinical significance of a potential long-term statin

induced deficiency of [CoQ] has not been established.... " The

Canadian lovastatin labeling contains substantially the same

statements. The Canadian atorvastatin and rosuvastatin labels are

similar to the Canadian simvastatin and lovastatin labeling in this

regard, but they also includes the following sentence: " It has been

reported that a decrease in myocardial [CoQ] levels could lead to

impaired cardiac function in patients with borderline congestive

heart failure.... " This labeling does not conclude that there is

reasonable evidence of an association between statin induced

decreases in coenzyme levels and heart function in patients with

borderline congestive heart failure. It only states that it has been

reported.

The FDA concluded its denial of Dr. Whitaker's petitions with the

following statement:

After a thorough review of the information submitted and currently

available, relevant scientific evidence, we conclude that there is no

reasonable evidence that statin-induced decreases in CoQ levels are

associated with impairment of myocardial function, liver dysfunction

or myopathies. Nor can we conclude that there is reasonable evidence

that CoQ supplementation with statins is associated with decreased

risk, prevention, or mitigation of such adverse events.

Accordingly, the requested boxed warning is not warranted because the

scientific data does not support the inclusion of such a warning

under the applicable legal standard. The current statin labeling

already includes the serious and rare side effects of statin therapy,

namely, muscle toxicity and liver dysfunction. We have also

determined (based on current, relevant scientific information) that

Medication Guides such as those you describe are not warranted.

Nonetheless, we continue to give careful consideration to any

relevant information that bears on the safe and effective use of

statins.

Dietary supplements, such as coenzyme Q10, are marketed in the U.S.

without their manufacturers having to demonstrate to the FDA that

they are safe and effective for any use. In addition, dietary

supplements are produced in facilities that do not follow FDA good

manufacturing practice regulations similar to those that must be

followed by producers of prescription and non-prescription drugs.

When a consumer purchases a dietary supplement, the consumer does not

know if what is listed on the label is actually in the bottle. This

sad state of affairs is the result of the Dietary Supplement Health

and Education Act (DSHEA) passed in 1994. This law opened the door

for dietary supplement industry and trampled on a basic American

right: the right of a marketplace free from untested products that

are promoted with unsubstantiated claims.

What You Can Do

You should not use coenzyme Q10 in an attempt to prevent or treat the

adverse reactions associated with the use of the cholesterol lowering

statin drugs.

Why do they flip/flop on their findings..... ALL THE DAMN TIME????

Hi Bogie,

As always there are two sides to every story and our "Spin Doctors" are always out there looking to discredit even the hallowed Vitamin C with over 10,000 independent clinical trial studies to support its efficacy. Did you know that the FDA has "grandfathered" in certain natural supplements like Aloe vera and colloidal silver? There are 2.3 million - I repeat - two million three hundred thousand articles on the efficacy of aloe vera. In the face of this overwhelming scientific proof, it is amazing to many observors like myself how the FDA still attempts to refute such evidence.

With permission, I will post several clinical data studies that absolutely recommend taking CO-q10 BEFORE and AFTER any heart surgery and most definitely with any statin drugs.

Think about this fact - We are BORN with CO-Q10- in our bodies. Do you think God and Mother Nature made a mistake? We are BORN with aerobic bacteria (good guys) to protect our intestines and colon. We are BORN with endorphins - natural pain killers to protect against pain signals.

I have more Faith in our Creator than the monopolistic greedy drug cartels and their unholy alliance with the AMA.
