See the DrugPatentWatch profile for lipitor

Lipitor, a medication commonly prescribed for lowering cholesterol levels, primarily targets low-density lipoprotein (LDL), also known as "bad" cholesterol [1]. By reducing LDL, Lipitor helps decrease the risk of heart disease and stroke.

However, Lipitor does not specifically reduce high-density lipoprotein (HDL), or "good" cholesterol [1]. In fact, some studies suggest that statins, the class of drugs that Lipitor belongs to, might modestly increase HDL levels [2]. Higher HDL levels are typically associated with a lower risk of heart disease [3].

In summary, Lipitor's primary function is to lower LDL cholesterol, and it does not directly reduce HDL cholesterol.
