The aim of this study was to evaluate the efficacy and safety of ezetimibe 10 mg added to atorvastatin 20 mg compared with doubling atorvastatin to 40 mg in patients with hypercholesterolemia at moderately high risk for coronary heart disease who did not reach low-density lipoprotein (LDL) cholesterol levels <100 mg/dl with atorvastatin 20 mg. In this 6-week, multicenter, double-blind, randomized, parallel-group study, 196 patients treated with atorvastatin 20 mg received atorvastatin 20 mg plus ezetimibe 10 mg or atorvastatin 40 mg for 6 weeks. Adding ezetimibe 10 mg to atorvastatin 20 mg produced significantly greater reductions in LDL cholesterol than increasing atorvastatin to 40 mg (؊31% vs ؊11%, p <0.001). Significantly greater reductions were also seen in non-highdensity lipoprotein cholesterol, total cholesterol, and apolipoprotein B (p <0.001). Significantly more patients reached LDL cholesterol levels <100 mg/dl with atorvastatin 20 mg plus ezetimibe compared with atorvastatin 40 mg (84% vs 49%, p <0.001). The 2 treatment groups had comparable results for high-density lipoprotein cholesterol, triglycerides, apolipoprotein A-I, and high-sensitivity C-reactive protein. The incidences of clinical and laboratory adverse experiences were generally similar between groups. In conclusion, the addition of ezetimibe 10 mg to atorvastatin 20 mg was generally well tolerated and resulted in significantly greater lipid-lowering efficacy compared with doubling atorvastatin to 40 mg in patients with hypercholesterolemia at moderately high risk for coronary heart disease.

Background-Despite the established efficacy of statins, many patients do not achieve recommended LDL cholesterol (LDL-C) goals. Contributing factors may be inadequate dosing, increased risk for adverse effects with high-dose monotherapy, and increased potential for intolerance and adverse effects with combinations of available agents. Methods and Results-In a double-blind study, 628 patients with baseline LDL-C 145 to 250 mg/dL and triglycerides Յ350 mg/dL were randomly assigned to receive 1 of the following for 12 weeks: ezetimibe (10 mg/d); atorvastatin (10, 20, 40, or 80 mg/d); ezetimibe (10 mg) plus atorvastatin (10, 20, 40, or 80 mg/d); or placebo. The primary efficacy end point was percentage reduction in LDL-C for pooled ezetimibe plus atorvastatin versus pooled atorvastatin treatment groups. Ezetimibe plus atorvastatin significantly improved LDL-C, HDL cholesterol (HDL-C), triglycerides, total cholesterol:HDL-C, and high-sensitivity C-reactive protein (hs-CRP) compared with atorvastatin alone (PϽ0.01).

Aim: Type 2 diabetes mellitus (T2DM) and metabolic syndrome (MetS) are both associated with increased risk for atherosclerotic coronary heart disease (CHD). Thus, it is useful to know the relative efficacy of lipid-altering drugs in these patient populations. Methods: A double-blind, parallel group trial of adult patients with hypercholesterolaemia at high-CHD risk receiving atorvastatin 40 mg/day compared atorvastatin 40 mg plus ezetimibe 10 mg (ezetimibe) vs. doubling atorvastatin to 80 mg. This post hoc analysis reports lipid efficacy results in patients grouped by diagnosis of T2DM, MetS without T2DM or neither. Per cent change from baseline at week 6 was assessed for LDL-C, total cholesterol, HDL-C, non-HDL-C, Apo A-I, Apo B and triglycerides. Safety was monitored through clinical and laboratory adverse events (AEs). Results: Compared with doubling atorvastatin, atorvastatin plus ezetimibe resulted in greater reductions in LDL-C, triglycerides, Apo B, non-HDL-C, total cholesterol and lipid ratios in the T2DM, MetS and neither groups. Treatment effects were of similar magnitude across patient groups with both treatments, except triglycerides, which were slightly greater in the T2DM and MetS groups vs. neither group. Changes in HDL-C, Apo A-I and high sensitivity C-reactive protein (hs-CRP) were comparable for both treatments in all three groups. Safety and tolerability profiles were generally similar between treatments and across patient groups, as were the incidence of liver and muscle AEs. Conclusions: Compared with doubling atorvastatin to 80 mg, addition of ezetimibe to atorvastatin 40 mg produced greater improvements in multiple lipid parameters in high-CHD risk patients with T2DM, MetS or neither, consistent with the significantly greater changes observed in the full study cohort (clinical trial # NCT00276484).

Background Despite the efficacy of statins in lowering low-density lipoprotein cholesterol (LDL-C) levels, many patients who are at high risk for heart disease with hypercholesterolemia require additional LDL-C level reduction. The cholesterol absorption inhibitor, ezetimibe, has been shown to provide significant incremental reductions in LDL-C levels when co-administered with statins. This study was performed to compare the efficacy and safety of ezetimibe (10 mg) plus response-based atorvastatin titration versus response-based atorvastatin titration alone in the attainment of LDL-C goals in subjects who are at high risk for coronary heart disease (CHD) and are not at their LDL-C goal on the starting dose of atorvastatin.

Background: Many patients on statin therapy do not achieve recommended LDL cholesterol goals. They require either high dose statin regimen or combination of statins with other lipid modifying agents. Ezetimibe is a novel drug when added to statins, will provide additional reduction in LDL-C level.Methods: Total 100 patients with CHD or hypertension and having serum LDL-C levels of ≥100 mg/dl were enrolled for the study and were randomly allocated to two groups. Baseline investigations done. Patients from Group I received Atorvastatin (10mg) per day orally and patients from group II received combination of Atorvastatin (10mg) and Ezetimibe (10mg) per day orally. Study treatment was started on the day of randomization and continued for 12 weeks and follow up visits were scheduled at 4, 8, and 12 weeks. During each follow up investigations repeated and patients were interviewed and examined for occurrence of any adverse effect.Results: There was greater reduction in levels of LDL-C, To...

Higher than 80% of coronary heart disease-related mortality occurs in patients >65 years of age. Guidelines recommend low-density lipoprotein (LDL) cholesterol targets for these at-risk patients; however, few clinical studies have evaluated lipid-lowering strategies specifically in older adults. This multicenter, 12-week, randomized, double-blind, parallelgroup trial evaluated the efficacy and safety of the usual starting dose of ezetimibe/ simvastatin (10/20 mg) versus atorvastatin 10 or 20 mg and the next higher dose of ezetimibe/simvastatin (10/40 mg) versus atorvastatin 40 mg in 1,289 hypercholesterolemic patients >65 years of age with or without cardiovascular disease. Patients randomized to ezetimibe/simvastatin had greater percent decreases in LDL cholesterol (؊54.2% for 10/20 mg vs ؊39.5% and ؊46.6% for atorvastatin 10 and 20 mg, respectively; ؊59.1% for 10/40 mg vs ؊50.8% for atorvastatin 40 mg; p <0.001 for all comparisons) and the number attaining LDL cholesterol <70 mg/dl (51.3% for 10/20 mg, 68.2% for 10/40 mg) and <100 mg/dl (83.6% for 10/20 mg; 90.3% for 10/40 mg) was significantly larger compared to those receiving atorvastatin for all prespecified dose comparisons (p <0.05 to <0.001). A significantly larger percentage of high-risk patients achieved LDL cholesterol <70 mg/dl on ezetimibe/simvastatin 10/20 mg (54.3%) versus atorvastatin 10 mg (10.9%, p <0.001) or 20 mg (28.9%, p <0.001) and ezetimibe/simvastatin 10/40 mg (69.2%) versus atorvastatin 40 mg (38.2%, p <0.001), and a significantly larger percentage of intermediate-risk patients achieved LDL cholesterol <100 mg/dl on ezetimibe/simvastatin 10/20 mg (82.1%) versus atorvastatin 10 mg (59.3%, p <0.05). Improvements in non-high-density lipoprotein cholesterol, total cholesterol, apolipoprotein B, and lipoprotein ratios were significantly greater with ezetimibe/simvastatin than atorvastatin for all comparisons (p <0.01 to <0.001).

Synopsis: Obesity, metabolic and inflammatory factors increase coronary heart disease (CHD) risk, and conceivably affect lipid altering drug efficacy. Purpose: Assess the influence of obesity, impaired fasting glucose, and inflammatory status on the efficacy of ezetimibe 10 mg (E) added to atorvastatin (A) vs. doubling of A in hypercholesterolemic patients at moderately high risk (MHR-none with diabetes) or high risk (HR-53% with diabetes) for CHD. Methods: Post-hoc analysis of two multicenter, 6-week, double-blind, randomized, parallel group trials. MHR patients on A20 mg were randomized to A20 mg 1 E or A40 mg. HR patients on A40 mg received A40 mg 1 E or A80 mg. Percent of change in baseline lipids was assessed in patient subgroups with baseline body mass index (BMI) ,30 or 30kg/m2;fastingbloodsugar(FBS),100or30 kg/m2; fasting blood sugar (FBS) ,100 or 30kg/m2;fastingbloodsugar(FBS),100or100 mg/dl, and high-sensitivity C-reactive protein (hsCRP) ,1, 1-3, or .3 mg/L. Assessment was conducted using the full analysis set approach (all randomized patients taking $ 1 dose of study medication, and having a baseline value and at least 1 post-baseline value).
