Statins: how it works, status and trials

Approved (generic)PillLowering LDL cholesterol

Statins slow the liver's production of cholesterol. With less cholesterol inside, liver cells add more LDL receptors, which pull more LDL out of the blood.

In technical terms: Block the rate-limiting step of cholesterol synthesis. Lower liver cholesterol activates SREBP-2, which raises LDL-receptor (and PCSK9) production.

Where it fits in the body

Cholesterol synthesis and absorption

When the liver has less cholesterol, whether because synthesis is blocked (statins, bempedoic acid) or less arrives from the gut (ezetimibe, bile acid sequestrants), SREBP-2 switches on the LDL-receptor gene and the liver pulls more LDL out of the blood. SREBP-2 also raises PCSK9, which is one reason PCSK9 inhibitors add well to statins.

Common questions

▸How does Statins work?

Statins slow the liver's production of cholesterol. With less cholesterol inside, liver cells add more LDL receptors, which pull more LDL out of the blood. In technical terms: Block the rate-limiting step of cholesterol synthesis. Lower liver cholesterol activates SREBP-2, which raises LDL-receptor (and PCSK9) production. It acts on HMG-CoA reductase · liver.

▸How much does Statins lower cholesterol or other lipids?

LDL-C −30% to ≥50% by intensity; major vascular events ↓ ≈ 22% per mmol/L LDL-C. Individual results differ, and a clinician can say what to expect for one person.

▸Is Statins approved, and what is the status?

Approved (generic) (curated October 25, 2026).

▸How is Statins taken?

Oral · daily.
