Effect of Coenzyme Q10 Supplementation on Simvastatin-Induced Myalgia
Abstract
Myalgia is the most frequently reported adverse side effect associated with statin therapy and often necessitates reduction in dose, or the cessation of therapy, compromising cardiovascular risk management. One postulated mechanism for statin-related myalgia is mitochondrial dysfunction through the depletion of coenzyme Q(10), a key component of the mitochondrial electron transport chain. This pilot study evaluated the effect of coenzyme Q(10) supplementation on statin tolerance and myalgia in patients with previous statin-related myalgia. Forty-four patients were randomized to coenzyme Q(10) (200 mg/day) or placebo for 12 weeks in combination with upward dose titration of simvastatin from 10 mg/day, doubling every 4 weeks if tolerated to a maximum of 40 mg/day. Patients experiencing significant myalgia reduced their statin dose or discontinued treatment. Myalgia was assessed using a visual analogue scale. There was no difference between combined therapy and statin alone in the myalgia score change (median 6.0 [interquartile range 2.1 to 8.8] vs 2.3 [0 to 12.8], p = 0.63), in the number of patients tolerating simvastatin 40 mg/day (16 of 22 [73%] with coenzyme Q(10) vs 13 of 22 [59%] with placebo, p = 0.34), or in the number of patients remaining on therapy (16 of 22 [73%] with coenzyme Q(10) vs 18 of 22 [82%] with placebo, p = 0.47). In conclusion, coenzyme Q(10) supplementation did not improve statin tolerance or myalgia, although further studies are warranted.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
