Optimizing LDL-C lowering with statins.
Clinical studies have demonstrated the efficacy of statins in reducing low-density lipoprotein cholesterol (LDL-C) and lowering coronary heart disease risk. However, many patients receiving statin therapy in clinical practice are not achieving their LDL-C goals. Generally, statins are initiated at starting doses, and doses should be titrated as needed until the goal of therapy is achieved or a second lipid-lowering drug is required; titration is required in the majority of patients who receive less efficacious agents. Most patients receiving statin therapy in clinical practice are maintained on their starting dose, and this frequently results in inadequate control of elevated cholesterol levels. A number of factors may limit dose titration in clinical practice, including the cost of therapy, safety of prescribing statins at high doses and the additional office visits required for evaluations and monitoring. There may be several solutions to this problem. The choice of statin appears to be one of the important factors influencing the success of therapy. Selecting a statin that provides greater LDL-C lowering enables more patients to achieve LDL-C goals, and the majority of patients can be effectively treated with starting doses of the more efficacious statins. Another factor influencing the success of therapy is the willingness to add other drugs to a statin to enhance LDL-C lowering. Choices here include niacin, a bile acid sequestrant, and ezetimibe, a new cholesterol absorption inhibitor. Of these approaches, use of a more efficacious statin is preferred to combination therapy because of cost, safety, effectiveness, and simplicity issues.
