You'll be pleased to hear that this is nothing to do with whether they're good, bad or indifferent. More to do with who they choose to do further research.
There is to be a £1 million trial into the danger of statins, examining the risk of muscle pain. One of the key researchers is Professor Jane Armitage, an expert in public health medicine at the University of Oxford. She is confident that statins do not increase the risk of muscle pain in most patients and believes side effects are rare. She has said "We are very anxious about adverse publicity on statins".
She heads up the Clinical Trial Service Unit and Epidemiological Studies Unit and I have no doubt of her credentials, but it would seem that she has already decided the results of any trial they do, which I find very worrying.
She obviously hadn't seen the Merck Pharmaceutical patent application of 1990 (yep, 26 years ago) that wanted to add CoQ10 to the statin to prevent skeletal muscular myopathy. Statins prevent CoQ10 uptake and that's what causes the muscle pain in some people who take statins.
