Study Notes
Drugs for Atherosclerosis Prevention
-
Statins: Inhibit HMG-CoA reductase, a rate-limiting step in cholesterol synthesis. Lower LDL cholesterol and cholesterol levels. Adverse effects include muscle pain (myopathy) and liver dysfunction. Typically used with statins.
-
Sterol Absorption Inhibitors (e.g., Ezetimibe): Inhibit cholesterol absorption in the gut, further lowering LDL cholesterol levels.
-
Fibric Acid Derivatives (e.g., Gemfibrozil): Reduce VLDL levels by increasing the breakdown of triglycerides and decreasing the secretion of VLDL from the liver, resulting in lower VLDL and triglycerides. Adverse effects include GI upset, myopathy, and hyperkalemia.
-
Bile Acid Binding Resins (e.g., Cholestyramine): Bind bile acids in the intestines, preventing their reabsorption and increasing their excretion. This increases cholesterol excretion and lowers LDL levels. Adverse effects are bloating and constipation.
-
PCSK9 Inhibitors (e.g., Alirocumab, Evolocumab): Inhibit PCSK9, a protein that reduces the liver's ability to remove cholesterol from the body. This leads to higher LDL removal. Adverse affects include mild skin rash and upper respiratory infections. Lowering LDL cholesterol when other drugs do not work. Used as a last resort when other drugs do not work. More expensive than the other classes. Difficult issues with compliances or infections.
