Praluent (Alirocumab)

Federico II University · FDA-approved active Small molecule

Alirocumab is a monoclonal antibody that binds to and inhibits PCSK9, a protein that degrades LDL receptors, thereby increasing LDL receptor availability and lowering blood LDL cholesterol.

Alirocumab is a monoclonal antibody that binds to and inhibits PCSK9, a protein that degrades LDL receptors, thereby increasing LDL receptor availability and lowering blood LDL cholesterol. Used for Hypercholesterolemia (heterozygous familial and non-familial) in patients not adequately controlled by statins, Homozygous familial hypercholesterolemia, Established cardiovascular disease (secondary prevention).

Mechanism of action

PCSK9 normally binds to LDL receptors on hepatocytes and promotes their degradation, reducing the liver's ability to clear LDL cholesterol from the blood. By blocking PCSK9, alirocumab prevents this degradation, allowing more LDL receptors to remain on the cell surface and increasing LDL cholesterol uptake from circulation. This results in significant reductions in plasma LDL cholesterol levels.
