Coronary Artery Disease Flashcards
Moderately High Risk patient LDL lowering drugs
<130 mg/dL
IHD patients high risk LDL levels target
< 100 mg/dL
Bile acid resins
Cholestyramine
Colestipol
Colesevelam
Mechanism: anion exchange resins (non absorbable, insoluble) bind bile acids within intestines & prevent them from being reabsorbed.
For lowering LDL-C
Should be taken before meals
GI tolerance, dyspepsia common
Statins
HMG CoA reductase Inhibitors
Inhibits HMG-CoA reduces cholesterol production
Lower LDL & triglycerides increase HDL
Statins
HMG CoA reductase Inhibitors
Inhibits HMG-CoA reduces cholesterol production
Lower LDL & triglycerides increase HDL
Statins precautions
GI effects
Elevatte LFT values alanine aminotransferase ALT
Aspartate aminotransferase AST
Myopathy lovastatin simvastatin
Elevate Creatin Kinase >10 times the upper limit with pravastatin
Cerivastatin removed from market for 31 patients rhabdomyolysis. Alone or in combo with gemfibrozil
Rhabdomyolysis monitoring in statins
Muscle symptoms check before therapy
Evaluate after 6 to 12 weeks after therapy
Muscle soreness tenderness pain should be immediately reported
Con current therapy with Cyclosporine Macrolide antibiotics Azole antifungal Niacin Fibrates Nefazodone Increases risk
Fibric acid derivative
Gemfibrozil
Fenofibrate
Inhibit cholesterol synthesis lower LDL-C and bile acids
Lower triglycerides & VLDL (very effective)
Gi adverse effects
LFT increase value
Increase CK
Rhabdomyolysis monitor
Niacin
Lower LDL-C triglycerides through participation in tissue respiration oxidation reduction reaction which decrease hepatic LDl & VLDL production
Inhibition of adipose tissue liploysis, decrease triglycerides esterification
Increase lipoprotein lipid activity
Niacin controlled release (Niaspan, Slo- Niacin)
Niacor (immediate release)
Niacin adverse effects
GI
Flushing itching skin
Liver toxicity
LFT should be performed
Ezetimibe
Zetia
Selectively inhibit intestinal absorption of cholesterol and related phytosterols
Adjunct therapy and dietary measures or in combo with statins
Dose 10 mg per day orally
With combo statins. LFT enzymes ALT may be increased (3 times)
