Abstract

Objective: Results of direct comparative studies between ezetimibe/simvastatin and rosuvastatin therapies have not been reported. Both of these treatment options offer significant reductions in LDL-C. To evaluate the lipid efficacy of each of these therapies relative to each other, a metaanalysis of data from 14 randomized, double-blind clinical trials that compared the effectiveness of two new options for cholesterol lowering was performed. Data sources: PubMed, EMBASE and BIOSIS databases were searched up to March 14,2004. Methods of study selection: Efficacy results from clinical trials with the co-administration of ezetimibe 10mg with simvastatin or with the ezetimibe/simvastatin combination product (ezetimibe/simvastatin 10/10 mg, 10/20mg, 10/40mg, and 10/80mg) were compared with efficacy results from clinical trials of rosuvastatin 5mg, 10mg, 20 mg, and 40 mg in patients with primary hypercholesterolemia. Trials in healthy patients, heterozygous familial hypercholesterolemia or combined hyperlipidemia, and pharmacokinetic trials were excluded. Data extraction and synthesis: This analysis used pooled data for LDL-C, HDL-C, non-HDL-C, triglycerides, total cholesterol, apolipoprotein (apo) A-I, and apo B for the two therapies at their lowest doses (ezetimibe/ simvastatin 10/10 mg and rosuvastatin 5mg) through their highest doses (ezetimibe/simvastatin 10/80mg and rosuvastatin 40 mg), and estimated within-treatment percentage changes in these parameters. Percentage reductions from baseline in LDL-C for the pooled data were 46.2% and 41.8% for ezetimibe/simvastatin 10/10 mg and rosuvastatin 5 mg, respectively; 50.6% and 47.4% for ezetimibe/simvastatin 10/20mg and rosuvastatin 10mg, respectively; 55.9% and 52.1% for ezetimibe/simvastatin 10/40mg and rosuvastatin 20 mg, respectively; and 59.7% and 58.5% for ezetimibe/simvastatin 10/80mg and rosuvastatin 40 mg, respectively. Conclusions: The results of this meta-analysis suggest greater LDL-C lowering with ezetimibe/ simvastatin compared with rosuvastatin. These results need to be confirmed in a head-to-head comparison of both therapies.
