CoEnzyme Q10 in Statin Myopathy
Statins (such as simvastatin or Zocor) are the most effective and widely prescribed medications to lower cholesterol levels and reduce the frequency of heart attacks, cardiac deaths and strokes. Unfortunately, statins can cause muscle discomfort or pain called "myalgia" in patients treated with these drugs. These symptoms often cause patients who need these medications to stop taking the drug. The cause of statin muscle pain is not known, but it is thought that a reduction of a vitamin-like substance called Coenzyme Q10 (CoQ10) during statin treatment may play a role. CoQ10 is a vitamin like substance and is not a drug approved and regulated by the Food and Drug Administration (FDA). This study will look at the effects of CoQ10 supplements on individuals who develop muscle symptoms while on simvastatin.
The investigators hope to test the hypothesis that CoQ10 supplementation compared to placebo in patients with documented statin myalgia reduces the intensity of pain during statin treatment.

- To test the hypothesis that CoQ10 supplementation compared to placebo in patients with documented statin myalgia reduces the intensity of pain during statin treatment. [ Time Frame: We selected 8 weeks of therapy . ] [ Designated as safety issue: No ]Increasing pain tolerability is a key clinical measure. We selected 8 weeks of therapy for the simvastatin vs placebo and CoQ10 vs placebo sections of the study because in the largest clinical study, the median time toonset of mylagia in statin naïve subjects was 1 month (4) and statin rechallenge typically reproduces symptoms more rapidly(3). Consequently, most subjects with true statin myalgia will have clearly developed symptoms at or before 8 weeks, the point at which study procedures are completed, allowing us to accurately assess the impact of CoQ10 on muscle pain intensity.
