Americans will still have to get a rx to buy statins. Neither Mevavor (in years past), nor Lipitor were given FDA permission to become OTC. Can't blame the manufacturers for trying (in different years), but in school one concept brought up was,"Where is the inexpensive OTC lab service to do periodic monitoring?
Granted it would be awesome if a patient could get lab services while waiting on a statin purchase, but often labs are expensive to set up.
Additional worries were probably: Is it normal muscle soreness or is it Rhabdomyolysis? Can we not mix statins and other OTCs? What about the statin-marijuana-alcohol combination?" 
For better or for worse, the FDA does not wish it. So let it be written, so let it be done.

From the peer reviewed literature below on the differences of US versus UK government opinion of statins.

Those in the UK can get simvastatin OTC, but only after consulting with a RPH.
