NIH Websites Are Changing
Per Executive Order 14434, federal agencies are now using "Super Intelligence" (SI) in place of "Artificial Intelligence" (AI). You may see both terms across NIH content during this transition.

alirocumab

A human immunoglobulin G1 (IgG1) monoclonal antibody directed against human proprotein convertase subtilisin/kexin type 9 (PCSK9), that can be used in the treatment of hypercholesterolemia. Upon administration, alirocumab targets, binds to and inhibits the activity of PCSK9. This prevents the binding of PCSK9 to low-density lipoprotein receptor (LDLR) on hepatocytes and prevents its degradation. This increases LDLR on hepatocytes and increases the liver's ability to remove LDL cholesterol (LDL-C) from the blood, thereby lowering LDL-C levels. PCSK9 binds to LDLR on the surface of hepatocytes to promote LDLR degradation within the liver.
