CoQ10 and its reaction with prescription drugs is touched on here:

http://www.justwebit.com/members/6584/coq10-side-effects.shtml

"Oral agents that lower blood sugar such as glyburide and
lipid-lowering drugs such as gemfibrozil and statins (lovastatin,
pravastatin, and simvastatin) limit the effectiveness of CoQ10. This
class of drugs cause a reduction in serum levels of CoQ10, resulting in
this limitation."

The National Cancer Institute also states:

"Certain lipid-lowering drugs, such as the "statins" (lovastatin,
pravastatin, and simvastatin) and gemfibrozil, as well as oral agents
that lower blood sugar, such as glyburide and tolazamide, cause a
decrease in serum levels of coenzyme Q10 and reduce the effects of
coenzyme Q10 supplementation. Beta-blockers (drugs that slow the heart
rate and lower blood pressure) can inhibit coenzyme Q10-dependent
enzyme reactions. The contractile force of the heart in patients with
high blood pressure can be increased by coenzyme Q10 administration.
Coenzyme Q10 can reduce the body's response to the anticoagulant drug
warfarin. Finally, coenzyme Q10 can decrease insulin requirements in
individuals with diabetes."
