To determine the effect of the combination of niacin and gemfibrozil on the lipid profile, a retrospective review was conducted of 161 patients who were prescribed a combination of gemfibrozil and niacin for 6 to 12 months at a community‐based lipid clinic. Low‐density lipoprotein (LDL) and high‐density lipoprotein (HDL) cholesterol, total cholesterol, triglycerides, ratio of total cholesterol to HDL, alanine aminotransferase (ALT), and weight were measured at entry to the clinic, 2 months after dietary instruction, during single‐agent therapy, and during combination therapy. Mean doses of niacin and gemfibrozil were 1,229 mg/day and 1,200 mg/day, respectively. Patient weight decreased significantly after dietary instruction and after institution of combination therapy. There were no significant changes in ALT levels with either single‐agent therapy or with combination therapy. The combination of niacin and gemfibrozil produced marked and significant changes in lipid levels: total cholesterol and LDL decreased by 14%, HDL increased by 24%, the ratio of total cholesterol to HDL decreased by 30%, and triglycerides decreased by 52%. The combination of niacin and gemfibrozil in the setting of dietary instruction has a marked beneficial effect on serum lipid levels, and was most effective in patients with initial levels of HDL <40 mg/dL, triglycerides >250 mg/dL, and LDL >160 mg/dL. No episodes of ALT elevation or symptomatic myositis were seen.
