I must let you know from experience with both drugs scientifically, Lipitor does lower your cholesterol levels, and when u want to talk cholesterol, talk, LDL's or HDL's donttalk general. Lipitor has been proven to reduce your LDL levels yes, but the standard dose regimen for Lipitor is 40 mg, NOT 10mg, further more once Lipitor does that at 40 mg, it ALSO STARTS LOWERING YOUR HDL's which are your good cholesterol. So dont be fooled that your cholesterol levels have dropped. Consider the patients out there who suffer from GENETIC/ FAMILIAL DYSLIPIDEMIA's . The game is totally different for GENETICALLY OBESE PAX as well.
