This retrospective study was carried out to assess the effectiveness of statin-gemfibrozil combination therapy in a community practice lipid clinic and to review safety data from published literature. Forty-six consecutive patients received a statin and gemfibrozil combination for resistant hyperlipidemia to either agent therapy. Fasting total cholesterol (mg/dL), high-density lipoprotein cholesterol (mg/dL), and triglycerides (mg/dL) were measured. Low-density lipoprotein cholesterol (mg/dL) was calculated using the Friedewald formula if triglycerides were <400 mg/dL. Combination therapy reduced total cholesterol, low-density lipoprotein cholesterol, and triglycerides by 11% (p=0.02), 22% (p=0.049), and 39% (p=0.0002), respectively, and raised high-density lipoprotein cholesterol by 5% (p=0.3). A pooled analysis of 838 patients from the literature on statin-gemfibrozil combination therapy revealed an incidence of myositis and severe myopathy of 0.7% and 0.6%, respectively (excluding cerivastatin). We conclude that statin-gemfibrozil combination therapy is effective in significantly reducing total cholesterol, low-density lipoprotein cholesterol, and triglycerides with a trend toward raising high-density lipoprotein cholesterol in patients with hyperlipidemia resistant to either agent alone. Myositis and severe myopathy are infrequent, but not rare side effects which may be statin-specific regarding the incidence of occurrence.
