What are the treatment options for hypertriglyceridemia?

From the Guidelines

Treatment of hypertriglyceridemia should prioritize lifestyle modifications, including a low-fat diet, reduced simple carbohydrate intake, increased physical activity, and weight loss, as first-line therapy, with medications such as fibrates, omega-3 fatty acids, and statins considered for patients with triglyceride levels above 500 mg/dL or those not responding to lifestyle changes alone, as recommended by the most recent guidelines 1.

Lifestyle Modifications

Lifestyle changes are essential in managing hypertriglyceridemia, with a focus on:

• Adopting a low-fat diet (less than 30% of calories from fat)
• Reducing simple carbohydrate intake
• Limiting alcohol consumption
• Increasing physical activity
• Achieving weight loss if overweight These modifications can help reduce triglyceride levels and decrease the risk of cardiovascular disease and acute pancreatitis.

Medications

For patients with triglyceride levels above 500 mg/dL or those not responding to lifestyle changes alone, medications may be necessary. Options include:

• Fibrates (e.g., fenofibrate, gemfibrozil) to reduce triglycerides by 30-50%
• Omega-3 fatty acids (2-4 grams daily) to reduce triglycerides and improve cardiovascular health
• Statins (e.g., atorvastatin, rosuvastatin) to reduce LDL cholesterol and triglycerides, particularly in patients with elevated LDL cholesterol
• Niacin (1-2 grams daily) to reduce triglycerides, although it may have more side effects

Severe Hypertriglyceridemia

For patients with severe hypertriglyceridemia (>1000 mg/dL), combinations of these medications may be necessary to reduce the risk of acute pancreatitis and cardiovascular disease. It is essential to individualize treatment based on the patient's specific needs and risk factors, as recommended by the American College of Cardiology 1 and the American Diabetes Association 1.

From the FDA Drug Label

1. 2 Severe Hypertriglyceridemia Fenofibrate tablets are also indicated as adjunctive therapy to diet for treatment of adult patients with severe hypertriglyceridemia. The initial treatment for dyslipidemia is dietary therapy specific for the type of lipoprotein abnormality. Excess body weight and excess alcoholic intake may be important factors in hypertriglyceridemia and should be addressed prior to any drug therapy. 2.3 Severe Hypertriglyceridemia The initial dose is 54 mg per day to 160 mg per day.

The treatment options for hypertriglyceridemia include:

• Dietary therapy: specific for the type of lipoprotein abnormality
• Lifestyle modifications: addressing excess body weight and excess alcoholic intake
• Fenofibrate tablets: as adjunctive therapy to diet, with an initial dose of 54 mg per day to 160 mg per day for severe hypertriglyceridemia 2 2

From the Research

Treatment Options for Hypertriglyceridemia

The treatment of hypertriglyceridemia involves a combination of lifestyle modifications and medication. According to 3, lifestyle modifications such as cessation of alcohol consumption, reduced intake of rapidly metabolized carbohydrates, weight loss, and blood sugar control are the most effective ways to lower triglyceride levels.

Medication Options

Several medication options are available for the treatment of hypertriglyceridemia, including:

• Fibrates: can lower triglyceride concentrations, but their efficacy in combination with statins has not been clearly shown in endpoint studies 3
• Omega-3 fatty acids: a daily dose of 2-4 g can lower triglyceride levels 3
• Statins: can exhibit a significant hypotriglyceridemic activity, especially in high doses 4, 5
• Niacin: can be effective in lowering triglyceride levels, but may have adverse effects 4, 6
• Volanesorsen: a new medication that works by binding to Apo C-III mRNA and degrading that mRNA, thus decreasing the synthesis of Apo C-III and increasing the binding of triglycerides to LDL receptors 7

Specific Treatment Strategies

The treatment strategy for hypertriglyceridemia depends on the severity of the condition and the presence of other risk factors. According to 4, patients with severe hypertriglyceridemia and abdominal pain or pancreatitis should be hospitalized and treated with hypolipidemic drugs and, if needed, with insulin/dextrose infusion or therapeutic apheresis. For patients with mild to moderate hypertriglyceridemia, statins remain the first line of therapy, but additional reduction in triglyceride-rich lipoproteins and remnant particles may be needed to further reduce residual cardiovascular risk 6.

Considerations for Treatment

When selecting a treatment option for hypertriglyceridemia, it is essential to consider the potential benefits and risks of each medication. According to 7, volanesorsen may cause a decrease in platelet count, renal toxicity, and elevate liver enzymes, which may limit its use in certain patients. In contrast, omega-3 fatty acids may be a well-tolerated and effective alternative to fibrates and niacin, but further large-scale clinical studies are required to evaluate their effects on cardiovascular outcomes and CVD risk reduction in patients with hypertriglyceridemia 6.

Key Points to Consider

• Hypertriglyceridemia is associated with an increased risk of cardiovascular events and acute pancreatitis 3, 4, 5
• Lifestyle modifications are the most effective way to lower triglyceride levels 3
• Medication options are available, but the choice of medication depends on the severity of the condition and the presence of other risk factors 3, 4, 5, 6, 7
• Potential benefits and risks of each medication should be considered when selecting a treatment option 6, 7
