From the Guidelines
Atorvastatin can lower triglycerides, although its effect is modest, typically reducing triglyceride levels by 10% to 15%. This is based on the guidelines from the Endocrine Society, as reported in the American Family Physician in 2013 1.
Key Points to Consider
- The primary approach to managing hypertriglyceridemia involves dietary counseling, weight loss, and increased physical activity, especially for patients with mild to moderate elevations in triglyceride levels.
- For patients with severe hypertriglyceridemia, the reduction of dietary fat and simple carbohydrates, along with drug therapy, is crucial to prevent pancreatitis.
- While statins like atorvastatin have a role in modifying cardiovascular risk, especially in patients with moderately elevated triglycerides, they are not the first-line treatment for severe hypertriglyceridemia.
Management Considerations
- Fibrates, niacin, and n-3 fatty acids are considered first-line treatments for patients with hypertriglyceridemia who are at risk of pancreatitis or have moderate to severe elevations in triglyceride levels.
- The treatment goal for patients with moderate hypertriglyceridemia includes achieving a non–high-density lipoprotein cholesterol level of 30 mg per dL higher than the low-density lipoprotein goal, as recommended by the NCEP ATP III.
- Lifestyle modifications, including weight loss, reduced alcohol consumption, limited intake of simple sugars, and regular exercise, are essential components of triglyceride management, alongside pharmacological interventions.
From the FDA Drug Label
Atorvastatin calcium reduces total-C, LDL-C, apo B, and TG, and increases HDL-C in patients with hyperlipidemia (heterozygous familial and nonfamilial) and mixed dyslipidemia The response to atorvastatin calcium in 64 patients with isolated hypertriglyceridemia treated across several clinical trials is shown in the table below (Table 10). For the atorvastatin calcium-treated patients, median (min, max) baseline TG level was 565 (267 to 1,502) Table 10: Combined Patients With Isolated Elevated TG: Median (min, max) Percentage Change From Baseline Atorvastatin 10 mg (N=37) TG -41 (-76.2, 49.4) Atorvastatin 20 mg (N=13) TG -38.7 (-62.7, 29.5) Atorvastatin 80 mg (N=14) TG -51.8 (-82.8, 41.3)
Atorvastatin can lower triglycerides. The drug label shows that atorvastatin calcium reduces TG levels in patients with hyperlipidemia and isolated hypertriglyceridemia. The median percentage change from baseline in TG levels for atorvastatin-treated patients ranged from -38.7% to -51.8% across different doses 2.
From the Research
Atorvastatin's Effect on Triglycerides
- Atorvastatin has been shown to lower triglyceride levels in patients with hypertriglyceridaemia 3, 4, 5.
- The mechanism by which atorvastatin reduces triglyceride levels is not fully understood, but it is thought to be related to its ability to inhibit HMG-CoA reductase 4.
- Studies have demonstrated that atorvastatin can reduce triglyceride levels by up to 43% in patients with triglyceride levels ≥3.1 mmol/L [≥273 mg/dL] [6].
- Atorvastatin's ability to lower triglyceride levels makes it a suitable treatment option for patients with combined hyperlipidaemia or hypertriglyceridaemia 4, 5.
Comparison to Other Statins
- Atorvastatin has been shown to be more effective than other statins, such as lovastatin, pravastatin, and simvastatin, in reducing triglyceride levels 4, 5.
- Atorvastatin's pharmacokinetic properties, including its longer plasma half-life and active metabolites, may contribute to its greater efficacy in lowering triglyceride levels 7.
Clinical Implications
- The ability of atorvastatin to lower triglyceride levels, in addition to its LDL-lowering effects, makes it a valuable treatment option for patients with dyslipidaemias 3, 5.
- Atorvastatin's triglyceride-lowering effects may also contribute to its ability to reduce cardiovascular risk in patients with hypertriglyceridaemia 6, 7.
