What is the best medication for lowering triglycerides?

Best Medications for Lowering Triglycerides

For patients with hypertriglyceridemia, fibrates are considered the most potent triglyceride-lowering agents, with gemfibrozil being the first-line treatment for severe hypertriglyceridemia (≥1500 mg/dL) and fenofibrate preferred for moderate hypertriglyceridemia, especially when combined with statins.

Treatment Algorithm Based on Triglyceride Levels

Severe Hypertriglyceridemia (≥500 mg/dL)

• Fibrates are the first-line treatment for severely elevated triglycerides (>500 mg/dL) due to the risk of pancreatitis 1
• Gemfibrozil (600 mg twice daily) is recommended as first-line treatment specifically for triglycerides ≥1500 mg/dL due to its well-established efficacy and safety profile 2
• Fibrates can reduce triglyceride levels by up to 50%, making them the most potent triglyceride-lowering agents available 1
• For triglycerides between 500-1500 mg/dL, either gemfibrozil or fenofibrate can be used as first-line treatment 2
• Prescription-grade omega-3 fatty acids (particularly icosapent ethyl) are an alternative option, reducing triglycerides by up to 40% 1
• Niacin can reduce triglycerides by up to 30% but should be used with caution due to potential increased risk of cardiovascular disease 1

Moderate Hypertriglyceridemia (200-499 mg/dL)

• For triglycerides between 200-499 mg/dL, treatment depends on clinical judgment 1
• Fenofibrate is preferred over gemfibrozil when combined with statins due to lower risk of myopathy 1, 2
• In clinical trials, fenofibrate has demonstrated triglyceride reductions of 29-54.5% 3, 4
• Icosapent ethyl (a highly purified omega-3 fatty acid) added to statin therapy reduces cardiovascular events in patients with triglycerides between 135-500 mg/dL who have established cardiovascular disease or diabetes plus two major risk factors 1

Mild Hypertriglyceridemia (150-199 mg/dL)

• Lifestyle modifications and statin therapy are the primary approach 1
• Encourage increased consumption of omega-3 fatty acids in the form of fish or capsules (1g/day) 1

Special Considerations

Diabetic Patients with Hypertriglyceridemia

• Improved glycemic control should be aggressively pursued first, as it can effectively reduce triglyceride levels 1
• Insulin therapy (alone or with insulin sensitizers) may be particularly effective in lowering triglyceride levels 1
• After optimizing glycemic control, consider adding a fibric acid derivative 1
• Fenofibrate treatment in diabetic patients with hypertriglyceridemia has shown benefits for both lipid profile and glycemic control 5

Combined Hyperlipidemia (Elevated LDL-C and Triglycerides)

• First choice: Improved glycemic control plus high-dose statin 1
• Second choice: Improved glycemic control plus statin plus fibric acid derivative 1
• Third choice: Improved glycemic control plus statin plus nicotinic acid 1
• When adding a fibrate to statin therapy, fenofibrate is preferred over gemfibrozil due to lower risk of myopathy 1, 2

Comparative Efficacy

• Fenofibrate has shown greater LDL-C lowering effects compared to gemfibrozil 6
• In head-to-head comparisons, fenofibrate demonstrated better effects on overall lipoprotein and metabolic profiles compared to omega-3 fatty acids, though both had similar effects on triglyceride reduction 4
• Fenofibrate at 400 mg/day has shown optimal lipid-lowering effects, reducing elevated VLDL-TG by 65% in type IIB + IV patients 7

Safety Considerations

• The combination of statins with fibrates increases the risk of myopathy 1
• This risk is higher with gemfibrozil than with fenofibrate when combined with statins 2
• Fenofibrate therapy has been associated with increases in serum aminotransferase levels, requiring regular monitoring of liver function 6
• Niacin should be used with caution due to potential side effects including flushing, hyperglycemia, and potential increased cardiovascular risk 1, 8

Remember that lifestyle modifications (weight management, physical activity, dietary changes including reduced intake of simple sugars and alcohol) remain essential components of triglyceride management for all patients 1.
