Exam 2: HLD Flashcards
Statins: MOA
HMG CoA reductase inhibitors (decrease cholesterol synthesis) Decrease LDL (upregulation of LDL receptors)
PSCK9i: Examples
Evolocumab (Repatha)
Alirocumab (Praluent)
PSCK91: MOA
Activate SREBP which inhibits PCSK9 and increase LDL receptors
Fibrates: MOA
Activate PPAR-alpha receptor
- increase lipoprotein lipolysis (increase HDL)
- decrease TG
- increase LDL size
Fibrates: examples
Gemfibrozil (Lopid)
Fenofibrate (Tricor)
Clofibrate (Atromid)
Fenofibric acid (Trilipix)
Niacin: MOA
Increase HDL and decrease hepatic synthesis/secretion VLDL
Bile acid sequestrants: Examples
Cholestryramine
Colestipol
Colesevelam
Bile acid sequestrants: MOA
Decrease LDL
Decrease intestinal reabsorption of bile (makes liver use cholesterol to make more bile)
Ezetimibe: MOA
Inhibit cholesterol absorption in small intestine
Ezetimibe dosing
5-10mg po daily
Counseling for statins and fibrates
Weakness/pain/fatigue
Counseling for niacin
Flushing (take ASA 325mg 30min before)
Counseling for bile acids
No drugs 2 hrs before and 4hrs after bile acids
Which medications do NOT require LFTs
Bile acids and ezetimibe
Which agent is most potent for increase HDL and decrease TG
Niacin
Which agent is mostly used for decrease LDL but not increase HDL and decrease TG?
Ezetimibe
What is the primary fxn of lipoproteins?
Transportation of TG and cholesterol from liver to tissues vice versa
Chlyomicron TG/Chol/Protein
90/5/5
VLDL TG/Chol/Protein
60/30/10
LDL TG/Chol/Protein
10/60/30
HDL TG/Chol/Protein
10/30/60
What is the fxn of HDL
Transport excess cholesterol from body to liver
What is the fxn of LDL
Transport cholesterol from liver to body
T/F: APO A1 is artherogenic
False – APO A1 is artheroprotective and APO B is artherogenic
LDL Size: Fluffy LDL is a/w ___ ASCVD risk
Less – fluffier the less ASCVD risk
