Similar trends were observed for changes in total cholesterol .
Implication sGiven the available data , the addition of ezetimibe to ongoing simvastatin , atorvastatin , or rosuvastatin monotherapy offers greater reduction in LDL-C among patients at high risk of CVD compared to doubling the initial statin dose
Purpose While statins are used as first-line treatments for high-risk patients with hypercholesterolemia , statin monotherapy is often insufficient to achieve target low-density lipoprotein cholesterol ( LDL-C ) levels .
Second-line treatment options include up-titration of statin dose , switching to a more potent statin , or combination therapy , e.g. , with ezetimibe .
The aim of this study was to evaluate the efficacy of adding ezetimibe to simvastatin , atorvastatin , or rosuvastatin monotherapy versus doubling the dosage or switching to a higher-potency statin in a population of patients with hypocholesterolemia at high risk of cardiovascular disease ( CVD ) and who had been previously treated with a statin .
Safety and efficacy of ezetimibe added to atorvastatin versus up titration of atorvastatin to 40 mg in Patients > or = 65 years of age (from the ZETia in the ELDerly [ZETELD] study).
Few clinical studies have focused on the efficacy of lipid-lowering therapies  in patients > or = 65 years of age . The percentage of change from baseline in low-density lipoprotein ( LDL ) cholesterol and the percentage of patients achieving prespecified LDL cholesterol levels after 12 weeks of ezetimibe 10 mg plus atorvastatin versus up titration of atorvastatin were assessed in subjects > or = 65 years old with hyperlipidemia and at high risk of coronary heart disease . After stabilization of atorvastatin 10-mg therapy , 1,053 patients , > or = 65 years old , at high risk of coronary heart disease , with and without atherosclerotic vascular disease and a LDL cholesterol level that was not < 70 or < 100 mg/dl , respectively , were r and omized to receive ezetimibe added to atorvastatin 10 mg for 12 weeks versus up titration to atorvastatin 20 mg for 6 weeks followed by up titration to atorvastatin 40 mg for an additional 6 weeks . Ezetimibe added to atorvastatin 10 mg result ed in significantly greater changes at week 6 in LDL cholesterol ( p < 0.001 ) , significantly more patients with atherosclerotic vascular disease achieving a LDL cholesterol level of < 70 mg/dl ( p < 0.001 ) , and significantly more patients without atherosclerotic vascular disease achieving a LDL cholesterol level of < 100 mg/dl ( p < 0.001 ) at weeks 6 and 12 compared to atorvastatin 20 mg or atorvastatin 40 mg . In addition , ezetimibe plus atorvastatin 10 mg result ed in significantly greater changes at week 6 in total cholesterol , triglycerides , non-high-density lipoprotein ( HDL ) cholesterol , apolipoprotein B ( all p < 0.001 ) , and HDL cholesterol ( p = 0.021 ) compared with atorvastatin 20 mg and significantly greater changes at week 12 in LDL cholesterol , non-HDL cholesterol , apolipoprotein A-I ( p = 0.001 ) , total cholesterol , apolipoprotein B ( p < 0.030 ) , and HDL cholesterol ( p < 0.001 ) compared with atorvastatin 40 mg . Both treatments were generally well tolerated , with comparable safety profiles . In conclusion , adding ezetimibe to atorvastatin 10 mg produced significantly greater favorable changes in most lipids at 6 and 12 weeks and significantly greater attainment of prespecified LDL cholesterol levels than doubling or quadrupling the atorvastatin dose in patients > or = 65 years old at high risk for coronary heart disease
