BACKGROUND: Dyslipidemia is a major risk factor for cardiovascular disease and is treated with many effective lipid-lowering agents. Statins are often used alone or in combination with fibrates. Combination therapy is more effective due to their comparative actions, but the increased incidence of side effects should be considered carefully. RESEARCH DESIGN AND METHODS: A meta-analysis of published data was conducted to compare the safety and efficacy of statins alone versus statins plus fibrates in patients with dyslipidemia. In total, nine articles were assessed for efficacy analysis and ten articles were assessed for safety analysis. RESULTS: In the efficacy analysis, a combination of statins and fibrates provided significantly greater reductions in total cholesterol (SE = 0.430; 95% CI 0.315-0.545), LDL cholesterol (SE = 0.438; 95% CI 0.321-0.555) and triglycerides (SE = 0.747; 95% CI 0.618-0.876), and a significantly greater increase in HDL cholesterol (SE = 0.594; 95% CI 0.473-0.715) than treatment with statins alone. In the safety analysis, treatment with statins alone was associated with a significant reduction in the numbers of total adverse events (RR = 0.665; 95% CI 0.539-0.819), liver-related adverse events (RR = 0.396; 95% CI 0.206-0.760) and kidney-related adverse events (RR = 0.146; 95% CI 0.075-0.285). CONCLUSION: We suggest that treatment with statins plus fibrates provides clinical benefits over treatment with statins alone but increased risks, especially of hepatic or renal side effects, should be monitored carefully.
