Slo-Niacin and atorvastatin (Lipitor) are both drugs that lower cholesterol. In this research, we will compare the effectiveness of Slo-Niacin and atorvastatin taken alone and together. This study will help show how the individual benefits of the two drugs taken separately can be combined when taken together.
Combined niacin and a statin treatment has greater potential value than either agent alone for the dyslipidemia of insulin resistance, obesity and the metabolic syndrome. The efficacy of Slo-Niacin and atorvastatin has not been formally examined in this setting.
Methods: Forty-four dyslipidemic men and women (LDL-C >130mg/dL and below average HDL-C (<55 in women and <45 in men) were randomized to a 3 month course of atorvastatin 10 mg or Slo-Niacin increased monthly at doses of 500, 1000 and 1500 mg/day. The alternate drug was added in the second 3-month segment. Lipid profiles and transaminase measurements were obtained monthly and full lipoprotein quantifications, apoproteins, remnant like lipoproteins (RLP), LDL buoyancy, glucose, insulin, and C-reactive protein were measured at the end of each 3-month sequence. Results: Mean entry lipids were (mg/dL) TG 187, LDL-C 171, HDL-C 39. Mean BMI was 32.6 Kg/M2. When Slo-Niacin and atorvastatin were given alone, respective decreases in triglyceride (TG) were 18% and 10%, LDL-C 12% and 36% and non-HDL-C 15% and 36%. HDL-C increased 8% and 6%, respectively. Combined therapy decreased median TG 33% and mean LDL-C 43% and increased mean HDL-C 10%. Mean hs CRP decreased 23% and RLP 44.5% in the combined groups. Conclusions: Slo-Niacin with atorvastatin improves all lipoprotein fractions, RLP and hsCRP in combined hyperlipidemia. The reduction of LDL with the drug combination is equivalent to that obtained with 20-80 mg of atorvastatin alone.
