OBJECTIVE: To determine the multiple functions of policosanol in elderly dyslipidemia patients.There were 294 elderly dyslipidemia patients enrolled into this clinical study. They were randomly divided into four groups, as follows: 20 mg policosanol (group A, n = 64); 10 mg policosanol (group B, n = 72); 20 mg atorvastatin (group C, n = 91); and 10 mg policosanol + 20 mg atorvastatin (group D, n = 62). Plasma platelet count, platelet aggregation rate, circulating endothelial cell (CEC) count, high sensitivity C-reactive protein (hs-CRP), and carotid intima-media thickness (IMT) were measured before the study (week 0) and at weeks 12, 24, and 52.
RESULTS: In group A, the platelet aggregation rate caused by adenosine diphosphate (ADP) after treatment was significantly decreased compared with before treatment (48.79% ± 20.29% vs. 40.37% ± 23.56%), but the arachidonic acid (AA)-induced platelet aggregation rates were similar. The platelet aggregation rates induced by AA and ADP in groups B, C, and D did not change significantly. CEC counts and hs-CRP and homocysteine levels in all groups after treatment were significantly lower compared with before treatment, but carotid IMTs were similar.
CONCLUSION: Policosanol regulates blood lipid levels and improves endothelial cell function, and it could delay the progress of atherosclerosis.ChiCTR-RRC-17013396 (retrospectively registered).
