Efficacy and Safety of Policosanol Plus Fenofibrate Combination Therapy in Elderly Patients with Mixed Dyslipidemia: A Randomized, Controlled Clinical Study.

BACKGROUND: Policosanol is a mixture of long-chain alcohols isolated from sugar cane. This controlled, randomized clinical trial was designed to compare the efficacy and safety of fenofibrate, policosanol and a combination of these 2 in lowering low-density-lipoprotein cholesterol (LDL-C) in elderly patients with mixed dyslipidemia.

METHODS: A total of 102 patients aged ≥60years were randomly assigned into 3 groups: patients receiving a 24-week therapy of fenofibrate (200 mg/day), policosanol (20 mg/day) or fenofibrate + policosanol combination. Lipids were evaluated at baseline, after 16 and after 24 weeks of therapy. Brachial-ankle pulse wave velocity (ba-PWV) was performed, and SF-36 questionnaires were used to evaluate the patients' quality of life. The primary endpoint was the percentage reduction in LDL-C. The secondary end points included percentage change in nonhigh density lipoprotein cholesterol (non-HDL-C), total cholesterol (TC), triglyceride, high-density-lipoprotein cholesterol (HDL-C), ba-PWV and SF-36 scores. Safety was assessed by adverse events and laboratory parameters.

RESULTS: LDL-C, non-HDL-C and TC were decreased, respectively after treatment with policosanol for 24 weeks (P < 0.01). Treatment with policosanol + fenofibrate resulted in significantly greater reductions in TC, non-HDL-C and LDL-C compared to fenofibrate alone (P < 0.01, respectively). There were significant increases in SF-36 scores in the policosanol and policosanol + fenofibrate groups (P < 0.05), and significant improvements of ba-PWV in the 2 groups (P < 0.01). There were no serious adverse events or significant changes in laboratory variables after any of the treatment regimens.

CONCLUSIONS: Policosanol + fenofibrate combination therapy significantly improved lipid parameters, arterial stiffness, and quality of life, with good tolerability.
