Pharm III Lipids Flashcards
HMG-CoA Enzyme reductase Inhibtors (Statins)
Blocks HMG-CoA Reductase–> Intracellular depletion of cholesterol–> Inc. binding of LDL by Rec.; Dec.LDL
DOC for H-LDL and CHD risk; CI- PREGO X; Myalgia, Myopathy, Rhabdo, HepToxic; Baseline, 6wk, 12 wk LFT
HMG-CoA Enzyme Reductase Inh. Drug Interactions
Fibric Acid derivatives; Gemfibrozil (No Combo Statin)
Prego X; NO CHF Pts;; Hemodialysis
Niacin–> Inc. risk of severe myopathy, rhabdo, hepatoxicity; Grapefruit Inh CYPSA4; Red yeast rice Inc. Myopathy and Rhabdo; Cytochrome p450
Statins (HMG-CoA Reductase Inh.) with no renal insufficiency
Atorvastatin
Pitavastatin
High Intensity Statin class that lowers LDL by approx 50%
Atorvastatin 40-80mg

- Pitavastatin (HD) -Pravastatin (HD)
- Lovastatin (HD) - Fluvasttatin (HD)
- Rosuvastatin (LD) -Atorvastatin (LD) -Simvastatin
Low intensity statin class that lowers LDL by 30%
- Pravastatin -Pitavastatin
- Lovastatin -Fluvastatin
- Simvastatin
Initiation of Statin Therapy in Pt w/ Clinical ASCVD
- Fasting Lipid panel -ALT
- CK -2ndary Statin safety consider
<75 W/O CI= HI >75 W/ CI=Mod. I
Initiation of statin W/No Clinical ASCVD
-Add A1C Pts w/o ASCVD –> No Diabetes 40-75
Fibric Acid Derivatives (Fibrates)
Stimulate Lipoprotein Lipase Activity–>Red.Lipogenesis
Raises LDL and Lowers TG by30-55%, Inc. HDL 18-22%
Use: Dec hypertiglyeridemias, include HIV protease tx
PREGO C; No monitor; No Statin Combo (Gemfibrozil)–> Rhabdo, Myopathy, GI S/S
Inc. Warfarin effects; CI-Severe renal or hepatic disease
Fibric Acid Derivatives (Agents)
- Gemfibrizol (w/food) -Fenofibrate
- Fenofibric Acid
Nicotinic Acid (Niacin)
Inhibits the hepatic synthesis of VLDL by inh. Lipolysis in adipose tissue–> Dec. Free FA–>Dec. LDL
Lower LDL 15-26%
Lower TG 20-50%
Raises HDL 20-50%
Reduces Major coronary events
Niacin (Nicotinic Acid)
Use;Combo w Resin or HMG-CoA Red inh. to normalize LDLw/ Family Hx of hypercholestererolemia/triglecerimia
AE: PREGO C ; Flushing, Warmth, Upper GI distress, Inc Hepatic Transaminase; Hepatoxic, Hyperglycemia/ Hyperurecemia/Gout; Req. LFTs c 6-12 wks
Bile Acid Sequestrants (Bile Acid Binding)
Anion exchange resins bind Neg. charge bile acids/salt
Small intestine–> Dec LDL from Inc. Bile Produce
AE: GI Distress/constipation/Bloating;Dec. Tolerance 40%
Dec. Vit. ADEK and Other Rxs Admin 1-2 hrs bef or4-6 aft
CI: >400 TG –> VLDL Synth from TG
Bile Acid Sequestrants (Bile Acid Binding)
- Colistepol (Prego B) -Cholestyramine
- Colesevelam (Prego B) Fewer GI AE;
Ezetimibe
Selective Cholesterol intest. Absorption Inhibitor of cholesterol; nhibits cholesterol reabsorpt in bile
Lowers-LDL 18-20% HDL- Raises Lower TG-7-17%
Adjunct to Statin >25% add Dec. LDL; Prego C
Take Bile sequestrans 2 hrs before or 4-6 hrs after Rx
