Barry Keate, has lived with tinnitus over 40 years and has published 150+ research articles on numerous aspects of tinnitus. He is an expert on the condition and a well-known advocate for those with tinnitus.
Statin medications, such as Lipitor, Mevacor, Crestor, Zocor, and others, are frequently prescribed to lower cholesterol levels. They significantly reduce the level of CoQ10 in the body resulting in deficiency of this critical compound.
Statin drugs are very expensive and come with significant side effects. The statin drug class is the largest and most profitable of all prescription medications, costing $22 billion per year in the US. This represents 8% of the total American drug cost of $270 billion. In this article we will explore the affect of statin drugs on critical ailments including tinnitus and how the compound Coenzyme Q10 (CoQ10) can mitgate the deleterious side-effects of these popular prescription medications.
To fully appreciate the tinnitus – CoQ10 connection it is important to review the recent history of this important enzyme and its relationship to disease states.
CoQ10 was discovered in 1957 by Frederick Crane. PhD, now at Purdue University in Indiana. Four years later, Peter D. Mitchell, PhD, of the University of Edinburgh, figured out how CoQ10 produces energy at the cellular level and won the 1978 Nobel Prize in chemistry for this discovery.
It is a fat soluble compound and is found in virtually every cell in the body. It is required for the conversion, or burning, of fats in the mitochondria of the cells to produce energy in the form of adenosine triphosphate (ATP). ATP is the energy powerhouse of the cells and provides energy for all cellular and biological operations. Without ATP production the cells and eventually the entire organism will die. CoQ10 is also a powerful antioxidant.
Coenzyme Q10 (also known as CoQ10) is a member of the ubiquinone family of compounds. Vitamins are coenzymes and both are necessary for fostering thousands of essential biochemical processes. Since the human body can synthesize coenzyme Q10 from food, it is not considered to be a vitamin. The name ubiquinone refers to the ubiquitous presence of these compounds in all living organisms. Now there is evidence that CoQ10 supplementation can be helpful for a certain subset of tinnitus patients, those who are deficient in CoQ10.
Most commercial CoQ10 consists of ubiquinone, which provides satisfactory absorption for most people. Those with advanced congestive heart failure are not able to absorb this properly due to fluid retention, or edema, which occurs in the liver and intestine in these critically ill patients. These patients should use the more absorbable form, Ubiquinol which has recently become commercially available. (See chart above.)
CoQ10 is synthesized in the body primarily from amino acids. These are found mainly in organ meats, poultry and fish with smaller amounts coming from soybean and canola oil, and nuts. Adequate vitamin B6 nutrition is essential for CoQ10 biosynthesis. The average dietary intake of CoQ10 in the western world is estimated at 3-5 mg/day.
According to the free radical and mitochondrial theories on aging, oxidative damage of cells by reactive oxygen species (ROS), often called free radicals, plays an important role in the functional declines that accompany aging.1 ROS are generated by mitochondria as a byproduct of ATP production. If not neutralized by antioxidants, ROS damage mitochondria over time, causing them to function less efficiently and to generate more damaging free radicals in a self-perpetuating cycle. Eventually the damaged cells are unable to continue operating and die. CoQ10 plays a central role in mitochondrial ATP production and also functions as an antioxidant in mitochondrial membranes. Tissue levels of CoQ10 have been reported to decline with age. 2
Two medical journal articles suggest tremendous promise in the treatment of cancer. One study conducted on 10 cancer patients who were also given CoQ10 for heart failure showed survival for periods of five to 15 years.3 Another study using CoQ10, antioxidants and essential fatty acids for 32 breast cancer patients found that all patients survived for 24 months when about 6 deaths would have been expected. One patient had a tumor removed surgically. It returned but stabilized at 1.5 – 2 cm after the patient began taking 90 mg CoQ10 daily. One month after increasing the dose to 390 mg, the tumor completely disappeared, confirmed by mammography.4
One of the most remarkable findings was that CoQ10 supplementation can extend the lifespan of patients with acquired immune deficiency syndrome (AIDS). In 1986 researchers began treating seven patients with HIV or AIDS. Not all the patients consistently took the CoQ10 but “treatment was very encouraging and at times even striking… All 7 patients felt better soon after starting on CoQ10.” 5
Oxidation of low-density lipoproteins (LDL) in arterial walls is thought to represent an early condition leading to the development of atherosclerosis (excessive plaque build-up in blood vessels). CoQ10 inhibits the oxidation of LDL. Studies with atherosclerotic mice found that CoQ10 supplementation significantly inhibited the formation of atherosclerotic lesions (arterial plaque).6
Human studies also show that CoQ10 is a valid adjunct treatment for cardiovascular disease. In particular, a study of heart attack patients showed that compared to placebo, supplementation with 120 mg per day of CoQ10 reduced secondary cardiac events by 45% and significantly reduced the number of cardiac deaths. All of these heart attack patients were prescribed a statin drug to lower cholesterol levels. The active group was taking both statin drugs and C0Q10 while the placebo group took only a statin medication. The major adverse effect of statin treatment was fatigue that occurred in 40.8% of the statin-only group but only 6.8% of the patients supplemented with CoQ10 expressed fatigue. 7
Massive advertising by drug companies has resulted in millions of Americans taking statin drugs every day. Statins have now become the most profitable drug class in the world. While statin drugs do lower cholesterol, there is controversy as to how effective these drugs are in extending overall life span.
Peter H. Langsjoen, MD ,a Texas cardiologist,is the foremost authority on the use of CoQ10 in the treatment of heart disease. His numerous research studies can be found in the world’s most prestigious scientific journals.
In 1990, the Proceedings of the National Academy of Science published Dr. Langsjoen’s studies on the safety of statin drugs. Dr. Langsjoen explained that the mechanism by which statin drugs lower cholesterol also inhibits the natural biosynthesis of CoQ10 in the liver. He wrote that he conducted these studies to learn “If lovastatin (Mevacor) were to reduce levels of CoQ10, this reduction would constitute a new risk of cardiac disease, since it is established that CoQ10 is indispensable for cardiac function.” Dr. Langsjoen then reported that his animal and human studies showed that lovastatin does indeed lower levels of CoQ10. He went on to describe case histories of his lovastatin patients who suffered from progressive cardiac degeneration but whose heart function improved after oral administration of CoQ10. 8
By July of 2002, Dr. Langsjoen had become a vocal critic of statin drugs and published a new paper titled “Statin-Induced Cardiomyopathy.” In an excerpt from this paper, Dr. Langsjoen describes his 17 year experience with statin drugs as follows:
“I have seen a frightening increase in heart failure secondary to statin usage…. Over the past five years, statins have become more potent, are being prescribed in higher doses, and are being used with reckless abandon in the elderly and in patients with normal cholesterol levels. 9
Dr. Langsjoen attributes these heart failure cases as being caused by “statin-induced CoQ10 depletion” that is preventable if stain drug users supplement with CoQ10.
The evidence supporting CoQ10 as an antidote to statin drug complications is so clear that in 1989 and 1990 Merck patented the use of CoQ10 in combination with statin drugs to both prevent and treat these complications. However, Merck has neither exercised these patents nor educated physicians or patients about the necessity of taking CoQ10 along with statin drugs. One of the two Merck patents states that:
“Since Coenzyme Q10…is of benefit in congestive heart failure patients, the combination with HMG-CoA reductase inhibitors (statin drugs) should be of value in such patients who also have the added risk of high cholesterol. 10
Based on the overwhelming body of evidence of CoQ10 depletion from statin drugs, Julian Whitaker, MD, filed a petition in 2002 against the FDA that meticulously documented the many lethal effects that would occur if patients prescribed statin drugs were not supplemented with CoQ10. The object of this petition was to force the FDA to mandate on the package insert that patients taking stain drugs should also take CoQ10.
Dr. Whitaker asserts that most patients and doctors do not realize that stain drugs block the production of CoQ10. He went on to describe how CoQ10 has been found to be essential for cellular energy production as well as for the functioning of the heart muscle. His petition stated, “Statin drugs have proven in clinical trials to deplete Coenzyme Q10, the ‘sparkplugs’ of the human body. Patients who take statin drugs without Coenzyme Q10, particularly those with a history of heart disease, are especially prone to developing complications that can have fatal consequences. 11
The FDA has ignored the petition and, to this date, has not responded.
The Tinnitus Connection
As far back as 1988, researchers were aware that CoQ10 was effective in promoting recovery from acute sudden deafness. A Japanese study was conducted on guinea pigs with acute sensorineural hearing loss artificially induced by hypoxia (lack of oxygen) conditions. The results showed that CoQ10 “is effective in promoting recovery from damage in auditory hairs as well as preventing respiratory metabolic impairment of hair cells due to hypoxia.” 12
Based on recent findings that CoQ10 can also be effective for treating hypertension, muscular dystrophy and neurodegenerative diseases, researchers in Berlin, Germany decided to study its effects on people with tinnitus.13 The study involved 20 patients with tinnitus and lasted for 16 weeks. Researchers recorded CoQ10 levels before the study began and used the Tinnitus Questionnaire (TQ) to evaluate efficacy. Patients were given 100 mg three times daily.
At the end of the study they found mean plasma concentration of CoQ10 significantly increased and was still elevated 4 weeks after the study ended. No statistical differences in Tinnitus Questionnaire scores were recorded.
However, a subgroup of 7 patients had significant reductions in questionnaire scores from 38 to 24. These responders had a reduction in all dimension of the TQ score compared with their initial values except for the dimension of emotional distress. The people in this group who responded well had a much lower level of CoQ10 before the study began than non-responders. Moreover, the increase of CoQ10 levels was significantly higher in responders than in non-responders. These results showed a significant improvement in tinnitus in those who initially had the lowest CoQ10 levels.
Everyone who is taking prescription statin drugs to lower cholesterol should be also taking supplemental CoQ10 to prevent damaging side-effects of the medication. Those who also have tinnitus, which most of our readership presumably has, should also use it for the potential of improving the condition.
Body Language Vitamin Company’s Anti-Age/Energy Formula was formulated by Michael Seidman, MD. The daily dosage includes 90 mg of CoQ10. It also includes therapeutic amounts of Acetyl-L-Carnitine, Alpha Lipoic Acid and Glutathione, all of which are mitochondrial metabolites which aid in the production of ATP and neutralize free radicals which are produced at the same time.
The product is protected by US Patent #5,977,162 relating to its benefit for hearing loss. Three additional patents are in progress related to: 1) Enhancement of mitochondrial function, 2) Natural increase in energy production and, 3) Positive support when taken two-three times per day on neurodegenerative disorders including Alzheimer’s and Parkinson’s diseases.
Author’s Comment: There are many safe and effective ways to reduce cholesterol without resorting to statin medications. Diet and exercise are both highly effective for this and also for reducing tinnitus. Many herbs, vitamins and other supplements are also helpful.
Omega-3 fatty acids found in fish oils reduce the risk of heart attack and lower cholesterol levels. Garlic does much the same. As discussed in last month’s article, B vitamins lower homocysteine, improving the health of arterial lining and preventing damage from plaque build-up. Niacin, or vitamin B3, is also known to lower cholesterol and, in high doses, can also help remove cholesterol from plaque in arterial linings.
Ginkgo biloba (found with garlic in Arches Tinnitus Relief Formula®) also protects blood vessels and lowers cholesterol levels. A recent study into the effects of Ginkgo biloba found that it significantly lowers free circulating cholesterol. 14
We do not advocate discontinuing any prescribed medication without the express approval of the prescribing physician. However, the addition of other therapies and supplements will help lower cholesterol and may lead to a reduced need for prescription medications.
