1) In studies comparing equal doses of Crestor to
Lipitor, Crestor has been shown to lower LDL levels ~10%
and increase HDL levels 2-4% more than Lipitor. Your triglyerides, total cholesterol, and LDL's are in the optimal range, and your HDL level is in the middle. Based on these numbers, there doesn't seem to be a need to switch to Crestor.
