Lipoprotein = lipid transport.

Causes of Hyperlipidemia Lifestyle Diabetes Mellitus Kidney disease Pregnancy Hypothyroidism Genetic Alcohol Dyslipidemia Drugs- Thiazides, Cyclosporin, Glucocorticoids, Beta Blockers..

Protein Phospholipid Cholesterol Triglyceride A. A lipoprotein 0000 0 Chylomicron — VI-DL HDL B. The variety Of lipoproteins Blood Lipids Serum Triglycerides • VLDL • CHYLOMICRONS Serum Cholesterol • LDL (Bad, 77.5%) • HDL (Good, 17.5%) IDL (Neutral, 5%).

1-chylomicron mainly T.G carry lipid from intestine to liver 2-VLDL mainly T.G from liver to blood 3-ILDL half cholesterol half T.G 4-LDL mainly cholesterol bad cholesterol 5-HDL from tissues to liver good cholesterol.

Antihyperlipedemic drugs. Hyperlipidemia SINGLE USE ONLY.

Classification. Statins Niacin Fibrates Bile acid resins, Ezetimibe.

BILE ACID-BINDING RESINS (CHOLESTYRAMINE) 1-Bind to bile acids in the intestine decrease cholesterol and T.G absorption 2-prevent their absorption and . preventing the recycling of bile acids, bile acid-binding resins divert hepatic cholesterol to synthesis of new bile acids, thereby reducing the amount of cholesterol..

Mechanism of action. نتيجة بحث الصور عن ‪bile binnding resin‬‏.

Side effect 1-GIT disturbance (steatorrhea) 2-decrease absorption of fat soluble vitamins 3-cholesterol gall stones.

EZETIMIBE.

Mechanism of action Selective inhibition of cholesterol absorption both 1-exogenous (dietary ) 2-endogenous (biliary).

Preparations (HMG CO A Reductase inhibitors) atorvastatin, simvastatin.

Mechanism of action Inhibition of HMG-co A reductase decrease so, inhibit synthesis of cholesterol in liver.
