Alirocumab works by inhibiting the PCSK9 protein.[8] PCSK9 binds to the low-density lipoprotein receptor (LDLR) (which takes cholesterol out of circulation), and that binding leads to the receptor being degraded, and less LDL cholesterol being removed from circulation. Inhibiting PCSK9 prevents the receptor from being degraded, and promotes removal of LDL cholesterol from circulation.[9]
After subcutaneous administration of alirocumab, maximal suppression of free PCSK9 occurs within 4 to 8 hours and has an apparent half-life of 17 to 20 days. Inhibition is dose-dependent. The antibody is distributed through the circulation, and it is eliminated at low concentrations by binding to its target, and at higher concentrations through a proteolytic pathway.

PCSK9
Proprotein convertase subtilisin/kexin type 9 (PCSK9) is an enzyme encoded by the PCSK9 gene in humans on chromosome 1. It is the 9th member of the proprotein convertase family of proteins that activate other proteins. Similar genes (orthologs) are found…
Ezetimibe inhibits the absorption of cholesterol from the small intestine and decreases the amount of cholesterol normally available to liver cells. The lower levels of cholesterol in the liver cells leads them to absorb more cholesterol from circulation and thus lowering the levels of circulating cholesterol. It blocks the critical mediator of cholesterol absorption, the Niemann-Pick C1-like 1 (NPC1L1) protein on the gastrointestinal tract epithelial cells, as well as in hepatocytes; it blocks aminopeptidase N and interrupts a caveolin 1–annexin A2 complex involved in trafficking cholesterol.
