Action ⬆ ⬇

A human monoclonal immunoglobulin (IgG1) produced in genetically engineered Chinese hamster ovary cells that binds to PCSK9, inhibiting its binding to the low-density lipoprotein receptor (LDLR) resulting in ↑ number of LDLRs available to clear LDL from blood.

Therapeutic effects:

Reduction in LDL-C in primary hyperlipidemia, HoFH, and HeFH.
Reduction in risk of MI, stroke, and unstable angina requiring hospitalization.

Classifications ⬆ ⬇

Therapeutic Classification: lipid-lowering agents

Pharmacologic Classification: proprotein convertase subtilisin kexin type-9 pcsk-9 inhibitors, monoclonal antibodies

Pharmacokinetics ⬆ ⬇

Absorption: Well absorbed (85%) following SUBQ administration.

Distribution: Mostly distributed in the circulatory system.

Metabolism/Excretion: Eliminated by binding to PCSK9 and by proteolytic degradation.

Half-Life: 17–20 days.

Time/Action Profile ⬆ ⬇

(effect on circulating unbound PCSK9)

ROUTE	ONSET	PEAK	DURATION
