Study Notes
Antihyperlipidemic Drugs Overview
- Hyperlipidemias can be primary (due to genetic factors) or secondary (due to metabolic disorders, diabetes, alcohol use, hypothyroidism, or primary biliary cirrhosis).
- Classification of hyperlipidemias includes Type I (familial hyperchylomicronemia), Type IIa (familial hypercholesterolemia), Type IIb (familial combined hyperlipidemia), Type III (familial dysbetalipoproteinemia), Type IV (familial hypertriglyceridemia), and Type V (familial mixed hypertriglyceridemia).
- Treatment goals for hyperlipidemias include decreasing lipoprotein production, increasing lipoprotein catabolism, and increasing cholesterol removal.
- Desired cholesterol levels are below 200 mg/dl, LDL ("bad") below 130 mg/dl, and HDL ("good") higher than 60 mg/dl.
- Nicotinic Acid (Niacin) inhibits hormone-sensitive lipase, reducing fatty acids, triglycerides, VLDL and LDL synthesis, and increasing HDL.
- HMG-CoA Inhibitors (Statins) competitively inhibit HMG-CoA reductase, effectively lowering plasma cholesterol in all types of hyperlipidemias.
- Fibrates (e.g., Fenofibrate, Gemfibrozil) decrease triglycerides, increase lipoprotein lipase, and moderately increase HDL levels, with potential adverse effects on the GI system and muscles.
- Bile Acid Binding Resins (e.g., Cholestyramine, Colestipol) bind bile acids in the intestine, reducing total cholesterol concentration, but may impair absorption of vitamins and interfere with drug absorption.
- Cholesterol Absorption Inhibitors (e.g., Ezetimibe) reduce serum LDL and triglycerides by inhibiting intestinal cholesterol absorption with less impairment in absorption of fat-soluble vitamins.
- Glycemic Drugs Overview
- Diabetes Mellitus Type 1 is genetic and affects younger patients, while Type II is usually due to diet and affects older individuals.
- Insulin comes in various forms including rapid-acting, intermediate-acting, and prolonged-acting, with different onset and peak actions. Intensive treatment aims for glucose level normalization with more frequent insulin injections, reducing long-term complications by 60%.
