Study Notes
Drugs for Dyslipidemias
- Dyslipidemia is a condition involving abnormal levels of lipids (fatty substances) in the blood.
- Lipids in the blood include triglycerides and cholesterol.
- Water-insoluble fats require apoproteins (specialized lipid-carrying proteins) for transport in the blood.
- Lipoproteins are combinations of triglycerides or cholesterol with apoproteins.
Types of Lipoproteins
- Chylomicron: Lowest protein content
- Very-low density lipoprotein (VLDL): Low protein content
- Low Density Lipoprotein (LDL): Less protein than high-density lipoprotein (HDL)
- Intermediate-density lipoprotein (IDL)
- High-density lipoprotein (HDL): Highest protein content
Coronary Heart Disease (CHD)
- Target total cholesterol in adults should be less than 200 mg/dL.
- LDL levels between 100 and 130 mg/dL may be acceptable for those without risk factors.
- High-risk individuals should aim for LDL levels below 70 mg/dL.
- High-risk factors include family history of premature heart disease (father or brother diagnosed before 55, or mother or sister before 65), smoking, obesity, and diabetes.
- Low levels of HDL (below 40 mg/dL) also present a high risk.
- Triglyceride target is less than 150 mg/dL.
Drugs for Dyslipidemia
- HMG-CoA reductase inhibitors (Statins): Lower cholesterol production in the liver
- Cholesterol Absorption Inhibitors (Ezetimibe)
- Fibric acid derivatives: Primarily lower triglycerides
- Niacin (nicotinic acid): Used to lower triglycerides, and cholesterol if used in combination with statins.
- Bile acid sequestrants (Colestipol, Cholestyramine): Reduce intestinal reabsorption of bile acids, affecting cholesterol levels.
Adverse Reactions
- Myositis and Myopathy (muscle pain) including localized or diffuse muscle groups, mild to severe/life-threatening conditions (renal failure/rhabdomyolysis). Risks are dose-related and influenced by drug interactions and diseases of the liver or kidneys, and advanced age
- Hepatotoxicity (liver damage): Possible asymptomatic liver effects
- Drug interactions: Statins, Niacin, Fibrates
Important Considerations
- Drugs for dyslipidemia are adjunctive to non-drug measures; their effects are predictable
- Combined treatments may be beneficial with additional risks
- Lipid-lowering drugs are not permanent cures
- Potential dangers during pregnancy and breastfeeding exist with these medications
- Patient treatment must consider actual lipid profiles, age, gender, other coronary risk factors, co-morbidities, and the effectiveness of non-drug measures
Additional Notes
- PCSK9 inhibitors (e.g., evolocumab) are newer medications that target PCSK9, an enzyme affecting LDL receptor activity in the liver.
- Lipid lowering implications require a thorough assessment of medical history, dietary habits, and lifestyle before medication initiation.
- Cautious use, monitoring for side effects, and patient counseling about long-term management are crucial.
