RESUMO
BACKGROUND AND OBJECTIVE: Elevated serum low-density lipoprotein cholesterol (LDL-C) is a major cardiovascular risk factor. This study aimed to determine the efficacy and safety of co-administration of the cholesterol absorption inhibitor ezetimibe with an HMG-CoA reductase inhibitor (statin) in the treatment of Mexican patients with dyslipidaemia who had not attained the LDL-C treatment goal with statin monotherapy. MATERIAL AND METHODS: We studied 256 patients with elevated serum LDL-C (as defined by the US National Cholesterol Education Program Adult Treatment Panel III guidelines) despite statin therapy. All patients had lipid profiles performed at baseline and after 6-8 weeks of treatment with statin therapy plus ezetimibe 10 mg/day for 6-8 weeks. RESULTS: Addition of ezetimibe to statin treatment reduced mean serum LDL-C levels significantly (from 160 +/- 42.8 to 100 +/- 36 mg/dL; p<0.001) after 6-8 weeks of treatment, with 61.7% of patients achieving LDL-C values below the goal established according to their coronary risk group. Serum LDL-C goals were achieved at the end of the study in 88.2% of the low-risk coronary group, 75.7% of the moderate-risk group and 47.8% of the high-risk group. Ezetimibe was well tolerated; no hepatic or muscle-related adverse events were observed. CONCLUSION: Addition of ezetimibe to statin treatment was both efficacious and safe when used for further reduction of serum LDL-C in dyslipidaemic patients who had not reached their LDL-C treatment goal while taking statin monotherapy.
