Abstract: BACKGROUND: Statins have emerged as the global leader in pharmacologic therapy for dyslipidaemia, and rosuvastatin has demonstrated clinical efficacy as well as safety in several clinical trials and postmarketing analyses. AIM: The present article reviewed the effects of rosuvastatin on the quantity and the quality of low-density lipoproteins (LDL). METHODS: We searched for and reviewed all the available evidence in a systematic way. A literature search (by Medline and Scopus) was performed using the following headings: 'LDL-cholesterol', 'LDL size', 'LDL subclasses', 'small dense LDL', 'apolipoprotein B, apo B' and 'rosuvastatin' up to 11 November 2008. The authors also manually reviewed the references of selected articles for any pertinent material. RESULTS: Rosuvastatin reduces LDL-cholesterol levels to a greater extent than other statins and is able to modulate significantly LDL size and subclasses towards less atherogenic particles as well as the LDL particle number, as indirectly measured by the levels of apo B. DISCUSSION AND CONCLUSIONS: The recent Justification for the Use of statins in Primary prevention: an Intervention Trial Evaluating Rosuvastatin study provides more evidence about the effectiveness of rosuvastatin therapy in reducing cardiovascular risk, even among persons who would not currently be considered for pharmacotherapy. Further insights on cardiovascular outcomes will be available by the on-going trials included in the GALAXY program that includes subjects with type-2 diabetes, haemodialysis recipients, patients with congestive heart failure and specific ethnic groups, such as African American, Hispanic and South Asian populations.

Abstract: Since their introduction in the 1980s, 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors (statins) have emerged as the one of the best-selling medication classes to date, with numerous trials demonstrating powerful efficacy in preventing cardiovascular outcomes. As our understanding of low-density lipoprotein cholesterol (LDL-C) and atherosclerosis continues to grow, the concept of 'lower is better' has corresponded with a more is better' approach to statin-based therapy. This review provides a detailed understanding of the clinical efficacy and safety of statins with a particular emphasis on the third generation drug, rosuvastatin.

Abstract: Since the identification of a fungal metabolite that inhibits HMG-CoA reductase in 1976, statins have emerged rapidly as the global leader in pharmacotherapeutics designed to lower low-density lipoprotein cholesterol (LDL-C). In conjunction, practice guidelines have recommended increasingly aggressive measures to improve coronary heart disease (CHD) outcomes by lowering LDL-C. By virtue of unique chemical characteristics, enhanced binding thermodynamics and limited cytochrome P450 3A4 metabolism, rosuvastatin calcium has a safety profile in line with currently marketed statins, but a different efficacy profile. Mirroring this chemical profile, the GALAXY program represents a comprehensive evaluation of the efficacy, safety and cost-effectiveness of rosuvastatin in individuals representing various clinical diagnoses, pathophysiological states and ethnicities. Also results from the Justification for the Use of statins in Primary prevention: an Intervention Trial Evaluating Rosuvastatin (JUPITER) study could provide further evidence for the use of rosuvastatin in individuals with traditional and emerging CHD risk factors, such as an elevated high sensitivity C-reactive protein level. This review will provide a comprehensive evaluation of the chemistry, clinical efficacy, safety and tolerability of rosuvastatin, and discuss the future role in the management of CHD and atherosclerosis.
