Atorvastatin and Coenzyme Q10: what the research found
PubMed indexes 8 records that name Atorvastatin and Coenzyme Q10 together, either in the title or in an interaction, co-administration, or pharmacokinetic context. The key findings come first, in the authors’ own words, followed by every study with its design and PubMed link.
A summary of published research, not medical advice. A pharmacist can check any combination against your full list of medicines and supplements.
Reviews and human studies first. Each quote is the authors’ own conclusion about their study, not a NutriStack assessment, and a single study is not a consensus.
“Amlodipine is able to neutralize the negative effect of atorvastin on the redox balance of CoQ10 in patients with CHF. An additional prescription of the antioxidant ethoxidol to standard therapy for patients with CHF was substantiated. Determination of the redox state of CoQ10 in plasma can be used to diagnose and assess the degree of oxidative stress in patients with cardiovascular diseases, as well as to assess…”
“Despite substantial increases in the serum Q10 and selenium levels following the oral supplementation, this study revealed no significant effects on SIM compared with the placebo.”
“In conclusion, long-term treatment with ATO might increase plasma levels of BNP in patients with CAD when it is accompanied by a greater reduction in plasma CoQ10. However, ATO-induced decreases in CoQ10 might not increase oxidative stress.”
The research
8 studies naming Atorvastatin and Coenzyme Q10.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
Journal of Zhejiang University. Science. B · 2016 · PMID 26739525
Comparative StudyAnimal study
“Co-administration of L-carnitine, but not coenzyme Q10, enhances the anti-osteoporotic effect of atorvastatin while antagonizing myopathy in ovariectomized rats. This could be valuable in treatment of osteoporotic patients. However, further confirmatory studies are needed.”
Names both Atorvastatin and Coenzyme Q10 in its title.
“Despite substantial increases in the serum Q10 and selenium levels following the oral supplementation, this study revealed no significant effects on SIM compared with the placebo.”

“In conclusion, long-term treatment with ATO might increase plasma levels of BNP in patients with CAD when it is accompanied by a greater reduction in plasma CoQ10. However, ATO-induced decreases in CoQ10 might not increase oxidative stress.”
Names both Atorvastatin and Coenzyme Q10 in its title.
“These changes in plasma CoQ10 levels showed no relation to the changes in serum AST, ALT and CK levels. Further studies are needed, however, for the evaluation of CoQ10 supplementation in statin therapy.”
Names both Atorvastatin and Coenzyme Q10 in its title.

Clinical TrialComparative Study
“Percent reductions of ubiquinol-10 and those of total cholesterol showed a positive correlation (r = 0.627, p = 0.0165). As atorvastatin reduces serum ubiquinol-10 as well as serum cholesterol levels in all patients, it is imperative that physicians are forewarned about the risks associated with ubiquinol-10 depletion.”
Names both Atorvastatin and Coenzyme Q10 in its title.
“P and A did not decrease CoQ10 despite a significant decrease in LDL levels. These findings suggest that HMG-CoA reductase inhibitors do not significantly decrease the synthesis of circulating CoQ10 in healthy subjects. Routine supplementation of CoQ10 may not be necessary when HMG-CoA reductase inhibitor therapy is administered.”
Names both Atorvastatin and Coenzyme Q10 in its title.
“Amlodipine is able to neutralize the negative effect of atorvastin on the redox balance of CoQ10 in patients with CHF. An additional prescription of the antioxidant ethoxidol to standard therapy for patients with CHF was substantiated. Determination of the redox state of CoQ10 in plasma can be used to diagnose and assess the degree of oxidative stress in patients with cardiovascular diseases, as well as to assess the efficacy and safety of ongoing pharmacotherapy.”
Names both Atorvastatin and Coenzyme Q10 in its title.

Animal study
“The combined use of CoQ10/atorvastatin could be a potential strategy to prevent CIN. However, future studies are warranted to test different combinations for longer prophylactic periods.”
Names both Atorvastatin and Coenzyme Q10 in its title.
Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.
How to read this page
A literature summary, not guidance.
A study listed here is not proof that Atorvastatin and Coenzyme Q10 interact. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
