Abstract

The oral administration of neomycin or niacin as single-drug therapy can significantly lower total and low-density lipoprotein cholesterol concentrations in patients with type II hyperlipoproteinemia. However, in the majority of patients treated with one of these drugs as sole therapy plasma lipid and lipoprotein concentrations do not normalize. The effect of combined neomycin (2 g/day) and niacin (3 g/day) treatment on the plasma lipoprotein concentrations was determined in 25 type II hyperlipoproteinemic patients in a double-blind, randomized, placebo-controlled, crossover clinical trial. Treatment with neomycin was well tolerated by all 25 study patients and significantly reduced total and low-density lipoprotein cholesterol concentrations by 23% and 29%, respectively (p < .05). In contrast to the well-tolerated neomycin regimen, 11 patients (44%) were unable to continue niacin treatment because of adverse side effects. In the 14 patients treated with both neomycin and niacin, niacin further lowered the concentrations of total and low-density lipoprotein cholesterol by 18% and 25%, respectively, and increased high-density lipoprotein cholesterol by 32% (p < .05) compared with that in the patients receiving neomycin plus niacin placebo. Compared with diet-only therapy, combined treatment with neomycin plus niacin reduced the total plasma cholesterol concentration by 36% low-density lipoprotein cholesterol by 45%, and the low-density lipoprotein/high-density lipoprotein ratio by 46% and it increased plasma high-density lipoprotein concentrations by 24% (p < .001). During the study, 80% of all the study patients and 92% of the patients who complied with the combined regimen normalized their total and low-density lipoprotein concentrations. No serious or irreversible adverse side effects were detected during combination neomycin/niacin treatment. These results indicate that the lipoprotein concentrations in a majority of type II hyperlipoproteinemic patients can be safely normalized by either therapy with neomycin only or by combined treatment with neomycin/niacin.
