Q

statin MOA

A

primarily works by interruption of the conversion of HMGCoA to mevalonate, which is the rate limiting step in cholesterol biosynthesis; Also reduce CoQ10; if pt takes CoQ10 supplements, that can reduce chance of myalgia

Q

bile acid sequestrants MOA

A

Binds bile acid in the intestinal lumen, which reduces enterohepatic circulation of bile acids. Indirectly increases clearance of LDL and decreases absorption; can bind co-administered drugs in the gut -> take 1hr before or 4hr after dimer

Q

niacin MOA

A

Reduces hepatic synthesis of VLDL which leads to reduces synthesis of LDL; Reduces HDL catabolism; Nicotinic acid affects lipids but nicotinamide does not

Q

fibrates MOA

A

Not fully understood, but appears related to PPARα which may increase lipoprotein lipase enhancing TG clearance and increase apoA expression which will increase HDL

Q

PCSK9 inhibitors MOA

A

Human monoclonal antibody to PCSK9 (proprotein convertase subtilisin kexin type 9, a protein that degrades the LDL receptor). Binds to PCSK9 and increases the number of LDL receptors available to clear circulating LDL.
