Objective
To assess the incremental low-density lipoprotein-cholesterol (LDL-C) lowering efficacy of doubling the statin dose or switching to the ezetimibe/simvastatin 10/20 mg combination tablet (EZE/SIMVA) in patients on simvastatin 20 mg or atorvastatin 10 mg not at LDL-C target < 2.5 mmol/L.
Study design and methods
Patients with documented coronary heart disease (CHD) and/or type 2 diabetes (DM2) with LDL-C > or = 2.5 and < 5.0 mmol/L despite treatment with atorvastatin 10 mg or simvastatin 20 mg were randomized to (1) double statin dose or (2) switch to ezetimibe/simvastatin 10/20, according to a PROBE study design. LDL-C, lipoprotein subfractions and safety data were assessed during the study.
Results
119 of 178 (67%) patients in the EZE/SIMVA group and 49 of 189 (26%) in the doubling statin group reached target LDL-C < 2.5 mmol/L. The odds ratio of success for EZE/SIMVA versus doubling statin treatment in reaching the LDL-C target of < 2.5 mmol/L was 5.7 (95% CI: 3.7-9.0, p < 0.0001). A reduction in total cholesterol (TC), total/high density lipoprotein (HDL) cholesterol ratio and apolipoprotein B was observed in both groups, but this reduction was significantly more pronounced in the EZE/SIMVA group as compared with the doubling statin dose group. Treatment was well tolerated and no difference was observed between the two groups with regard to adverse effects.
Conclusions
In CHD/DM2 patients treated with simvastatin or atorvastatin with LDL-C persistently > or = 2.5 mmol/L, switching to the EZE/SIMVA was more effective in attaining the LDL-C target of < 2.5 mmol/L than doubling the statin dose.
