Excerpt: Using Nutraceuticals to Reduce Side Effects of Prescription Drug
Integrative medicine is defined as “an approach to medical care that combines standard medicine with CAM (complementary and alternative medicine) practices that have shown through science to be safe and effective.”[i]
One area in which integrative medicine can be particularly useful is when specific nutraceuticals are used to help compensate for certain side effects caused by some prescription drugs.
Statins and Coenzyme Q10
Physicians often use statin medications as an important therapy in reducing and maintaining serum cholesterol levels in patients with hypercholesterolemia (i.e., high cholesterol levels). However, in addition to reducing cholesterol levels, statin medications also reduce the body’s production of coenzyme Q10 (CoQ10). In turn, this can lead to a myopathy marked by muscle pain in those patients prescribed a high statin dose.[ii]
In fact, the pharmaceutical suppliers of Lipitor (Pfizer)[iii], Zocor (Merck)[iv], and Crestor (AstraZeneca)[v] all state that significant decreases in circulating CoQ10 levels in patients treated with statins have been observed and that the clinical significance of a potential long-term, statin-induced deficiency of CoQ10 has not been established. This recognition is especially evident in the fact that Merck has even gone so far as to obtain two patents to combine CoQ10 with its statin drug.[vi]
Given the potential adverse effects of statin therapy, co-administration with CoQ10 makes a great deal of medical sense. In vitro research[vii] has established that pretreatment with CoQ10 reduced the toxic effects of statins and may protect cells from statin-induced injuries and alleviate their side effects.
Likewise, animal research[viii] demonstrated that CoQ10 supplementation improved metabolic parameters, liver function, and mitochondrial respiration in rats with high doses of atorvastatin and a cholesterol-rich diet.
Evidence from a review of human studies[ix] showed a benefit in symptoms of myalgia or improvement of serum levels of CoQ10 with supplementation of 30-200 mg daily of CoQ10, with no reported risks, in patients prescribed statins. In older athletes taking statins, 200 mg of CoQ10 daily improved muscle performance as measured by time to anaerobic threshold and leg strength. Many other measures of mitochondrial function also tended to improve.[x] Other research[xi] found that 200 mg of CoQ10 supplementation daily improved endothelial dysfunction in statin-treated type 2 diabetic patients, compared to placebo, possibly by altering local vascular oxidative stress.
