Re: Crestor v Zocor potency?
The Consumer Reports booklet you have on your website is very good; thanks for letting us know about it. I agree that anyone taking a statin, or thinking about taking a statin, should read it.
I do not interpret their recommendations on Lipitor as having anything to do with safety or effectiveness; they make several statements confirming its safety and effectiveness consistent with what I already know about the studies that have been done. Their recommendations are very reasonable overall, but they put a lot of emphasis on cost factors, which is important but may not be the most important depending upon a person's health condition and financial circumstances.
Lipitor costs more because it does not have a generic (yet). If it worked as well for me as Lipitor, I'd still be taking simvastatin myself. (I actually have fewer side effects with Lipitor...Zocor/simvastatin made me constipated, Lipitor does not). It looks to me like they picked two years mostly out of the air...note they say it assumes you have changed lifestyle issues and have switched to simvastatin.
Note also they do not recommend Crestor for any group of people, presumably because of cost, lack of "proof" that it prevents heart attacks while other statins already have this "proof," and potential safety issues.
