Dyslipidemia drugs Flashcards

1
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
