 Statin - CoQ10 suppression (Arch Neurol, 6/04)
1: Arch Neurol. 2004 Jun;61(6):889-92. Related Articles, Links Atorvastatin decreases the coenzyme Q10 level in the {*filter*} of patients at risk for cardiovascular disease and stroke. Rundek T, Naini A, Sacco R, Coates K, DiMauro S. Department of Neurology, Columbia University College of Physicians & Surgeons, New York, NY 10032, USA. BACKGROUND: Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) are widely used for the treatment of hypercholesterolemia and coronary heart disease and for the prevention of stroke. There have been various adverse effects, most commonly affecting muscle and ranging from myalgia to rhabdomyolysis. These adverse effects may be due to a coenzyme Q(10) (CoQ(10)) deficiency because inhibition of cholesterol biosynthesis also inhibits the synthesis of CoQ(10). OBJECTIVE: To measure CoQ(10) levels in {*filter*} from hypercholesterolemic subjects before and after exposure to atorvastatin calcium, 80 mg/d, for 14 and 30 days. DESIGN: Prospective blinded study of the effects of short-term exposure to atorvastatin on {*filter*} levels of CoQ(10). SETTING: Stroke center at an academic tertiary care hospital.Patients We examined a cohort of 34 subjects eligible for statin treatment according to National Cholesterol Education Program: {*filter*} Treatment Panel III criteria. RESULTS: The mean +/- SD {*filter*} concentration of CoQ(10) was 1.26 +/- 0.47 micro g/mL at baseline, and decreased to 0.62 +/- 0.39 micro g/mL after 30 days of atorvastatin therapy (P<.001). A significant decrease was already detectable after 14 days of treatment (P<.001). CONCLUSIONS: Even brief exposure to atorvastatin causes a marked decrease in {*filter*} CoQ(10) concentration. Widespread inhibition of CoQ(10) synthesis could explain the most commonly reported adverse effects of statins, especially exercise intolerance, myalgia, and myoglobinuria.

 Statin - CoQ10 suppression (Arch Neurol, 6/04)
Hardly a surprise finding. The body creates CoQ10 in the mevalonate pathway. Statins interrupt this pathway upstream of the CoQ10 production. This short-circuiting of the process makes it impossible for the body to produce this nutrient that is so essential to the mitochondria. Such study findings are roughly equivalent to "when the faucet turns off, the water flow stops." Necessary to measure the absence of the water, though, for all those who will doubt it.

 Statin - CoQ10 suppression (Arch Neurol, 6/04)
Doesn't supplementing with CoQ10 help solve the problem of statins preventing the body from making it? Something like 100 mg of CoQ10 in softgel form? Quote: > Hardly a surprise finding.

There are several studies showing statins deplete coenzyme q10. There are no double blind randomized studies which show taking CoQ10 will replenish statin-induced depletion and/or correct damage posited to be caused by the statin-induced depletion. Langsjoen and Folkers on Coenzyme Q10 and cardiomyopathy. Also more recent on www.pubmed.org http://www.***.com/ Zee Quote: > > Hardly a surprise finding.

From: http://www.***.com/ "HMG-CoA reductase inhibitors used to treat elevated {*filter*} cholesterol levels by blocking cholesterol biosynthesis also block CoQ10 biosynthesis (13). The resulting lowering of {*filter*} CoQ10 level is due to the partially shared biosynthetic pathway of CoQ10 and cholesterol. In patients with heart failure this is more than a laboratory observation. It has a significant harmful effect which can be negated by {*filter*}CoQ10 supplementation(14)." L.

"In patients with heart failure." These studeis deal with cardiomyopathy. Statin induced coenzyme q10 depletion is thought to have a far greater scope. There is nothing yet regarding generalized myopathy. Or cognitive adverse effect, or polyneuropathies, or.... Zee

Would suggest you confer with your doctor on the appropriate dosage amount (for you). Servant to the humblest person in the universe, Andrew -- Dr. Andrew B.
