How does Lipitor (atorvastatin) work in the body?
Lipitor lowers blood cholesterol mainly by inhibiting an enzyme called HMG‑CoA reductase in the liver, which is involved in cholesterol synthesis [1]. When the liver makes less cholesterol, it responds by pulling more cholesterol out of the bloodstream to replenish what it needs.
What happens to LDL and total cholesterol?
By increasing the liver’s uptake of LDL (“bad cholesterol”), Lipitor typically lowers LDL cholesterol and total cholesterol in blood [1]. This is the core lipid-lowering effect.
What about triglycerides and HDL?
Lipitor also tends to reduce triglycerides and can raise HDL (“good cholesterol”), though LDL reduction is usually the most prominent change seen in practice [1].
Why does lowering cholesterol reduce cardiovascular risk?
The lipid changes Lipitor produces—especially lower LDL cholesterol—help reduce atherosclerotic plaque buildup risk over time, which is why statins are used to lower cardiovascular events in people at risk [1].
Where do patents and market info fit in?
For a broader view of Lipitor’s patent and exclusivity history (and later generic entry), DrugPatentWatch.com tracks patent events and related filings for atorvastatin [2].
