Statins' effect on plasma levels of Coenzyme Q10 and improvement in myopathy with supplementation.J Am Assoc Nurse Pract. 2014 Feb; 26(2):85-90.JA
Heart disease is the leading cause of death in the United States. HMG-CoA reductase inhibitors, or statins, are medications at the forefront of the battle against cardiovascular disease. Despite their effectiveness, patient compliance with statins has lagged because of medication cost and adverse effects, namely myopathy. Myopathy is the most common side effect of statin use. The purpose of this review is to report plasma levels of CoQ10 in patients taking statins and then to determine the benefit of Coenzyme Q10 (CoQ10) supplementation on statin-related myopathy as evidenced by symptomatic improvement and increase in serum levels of CoQ10.
CINAHL, Medline, Health Source: Nursing/Academic Edition, and Cochrane Library.
Evidence from this review suggests that studies showed a significant relationship between statin intake and decreased serum levels of CoQ10. A few studies showed a benefit in symptoms of myalgia or improvement of serum levels of CoQ10 with supplementation. One study showed no benefit of CoQ10 supplementation when taken with statins. There were no risks of supplementation reported in any of the studies.
IMPLICATIONS FOR PRACTICE
CoQ10 supplementation might benefit those patients suffering from statin-induced myopathy as evidenced by the results of these studies. Supplementation of CoQ10 at a dose of between 30 and 200 mg daily has shown to have beneficial effects on statin myopathy with no noted side effects. Further research is necessary.
