Big Pharma is not in the Cure Business. That makes no commercial sense.
The research doesn't says statins cure disease but that they improves certain conditions.
My definition of a disease being cured may be different from the medical definition. If you need to continually take a drug to maintain normal levels of whatever, I personally wouldn't consider that a cure. For me, to be cured means there is no further need to take a drug or procedure to maintain or keep your health.
Per a friend who is an oncologist who was a pharmacist for 10 years before becoming a physician, “statins are poison.” Additional truth, if you want to kiss your sex life goodbye, by all means, suck down statins.” If you doubt that, research it and ask around. I sat next to a nurse at a mammogram center and she told me that she would “never ever” take a statin. To each his own as they say.
