- - Add-on therapy to statins
- - Decrease TG synthesis in liver
- - Decreases FFA --> liver, decreased TG & VLDL/IDL/LDL
- - Increases HDL
- - Facial flushing
- - IR, SR, ER formulations
-
Fibrates
- - First-line therapy for lowering TG
- - PPARα agonist
- - Upregulate LPL, which breaks down TG's to FFA's

Fenofibrate
- - Fibrate
- - No increased risk of myopathy + statin
-
Cholesterol Absorption Inhibitor
- - Add-on therapy to statins for lowering LDL (~18%)
- - Impacts NPC1L1 sterol transporter

- - Upregulation of LDL-R
- - Contraindicated in severe liver disease
-
Ezetimibe
- Cholesterol absorption inhibitor (only one)
-
Fish oils (Omega-3 FA's)
- - EPA & DHA

- - Decrease risk of sudden cardiac death (~1 g/day)
- - Smelling of fish
- - Better absorbed with food
- - Read the label to acheive needed dose
-
Plant Sterols
- - Competitively block cholesterol aborption in small intestines
