Theoretically yes, but practically no.

I know personally Few people who started on Lipitor & ended up using Crestor!!!

We taking about the finner differences here.

simply because a scientific article states how drugs comparatively works doesn’t mean that’s how they actually work in all their details!!  

For clarity, my point is that no one is on both statins at same time. 

So, why make the combination effect of both as the primary end point!!

There is alway a possibility that a positive effect of one will be cancelled out by the negative effect of the other!!!! 

I thought you would appreciate the potential impact of finner differences!!!
