Abstract: The importance of non-pharmacological control of plasma cholesterol levels in the population is increasing, along with the number of subjects whose plasma lipid levels are non-optimal, or frankly elevated, according to international guidelines. In this context, a panel of experts, organized and coordinated by the Nutrition Foundation of Italy, has evaluated the nutritional and lifestyle interventions to be adopted in the control of plasma cholesterol levels (and specifically of LDL cholesterol levels). This Consensus document summarizes the view of the panel on this topic, with the aim to provide an updated support to clinicians and other health professionals involved in cardiovascular prevention.

Abstract: The development of more active and safe new 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) will increase the armamentarium of therapeutic tools available to the physicians for antiatherosclerotic therapies. Rosuvastatin presents a promising pharmacological profile: high affinity for the enzyme, a relative high hydrophilicity, selective hepatic uptake and activity, minimal cytochrome P450-mediated metabolism. Clinically the drug displays the highest lipid-lowering efficacy in the class with a safety profile similar to the other statins. Drug interaction potential is reduced. Rosuvastatin effectively decreases triglycerides, triglyceride-rich lipoproteins, non-HDL cholesterol, and increases HDL cholesterol. All together these properties will favor the achievement of therapeutic goals in the treated patients.

Abstract: Statins effectively lower LDL-cholesterol and some members of this class have been shown to reduce the risk of major cardiovascular events and total mortality in patients with or at risk for coronary heart disease. Statins are in general well tolerated. Withdrawal rates related to adverse events are low (< or =3%). The most common adverse events are mild gastrointestinal symptoms. Elevated serum transaminase levels occur infrequently (< or = 1.5%). These are generally asymptomatic, reversible and rarely require drug withdrawal. Statins do not cause adverse endocrine effects, do not alter glycemic control in diabetic patients, and do not increase cancer risk. Dose-related myopathy and/or rhabdomyolysis also occurs very rarely, although the risk is increased by concomitant administration of cyclosporine, niacin, fibrates, or by CYP3A4 isoenzyme inhibitors (e.g. erythromycin, systemic azole antifungal agents etc.) with statins metabolized by this isoenzyme. The pharmacokinetics of the individual statin should be considered in patients receiving polypharmacological treatments, to minimize the risk of unfavorable drug interactions. Atorvastatin is well tolerated in long-term treatment of dyslipidemia and is characterized by a safety profile similar to the other available statins.

Abstract: The beneficial effects of statins are assumed to result from their ability to reduce cholesterol biosynthesis. However, because mevalonic acid is the precursor not only of cholesterol, but also of many nonsteroidal isoprenoid compounds, inhibition of 3-hydroxy-3-methylglutaryl coenzyme A reductase may result in pleiotropic effects. It has been shown that several statins decrease smooth muscle cell migration and proliferation and that sera from fluvastatin-treated patients interfere with its proliferation. Cholesterol accumulation in macrophages can be inhibited by different statins, while both fluvastatin and simvastatin inhibit secretion of metalloproteinases by human monocyte-derived macrophages. The antiatherosclerotic effects of statins may be achieved by modifying hypercholesterolemia and the arterial wall environment as well. Although statins rarely have severe adverse effects, interactions with other drugs deserve attention. Simvastatin, lovastatin, cerivastatin, and atorvastatin are biotransformed in the liver primarily by cytochrome P450-3A4, and are susceptible to drug interactions when co-administered with potential inhibitors of this enzyme. Indeed, pharmacokinetic interactions (e.g., increased bioavailability), myositis, and rhabdomyolysis have been reported following concurrent use of simvastatin or lovastatin and cyclosporine A, mibefradil, or nefazodone. In contrast, fluvastatin (mainly metabolized by cytochrome P450-2C9) and pravastatin (eliminated by other metabolic routes) are less subject to this interaction. Nevertheless, a 5- to 23-fold increase in pravastatin bioavailability has been reported in the presence of cyclosporine A. In summary, statins may have direct effects on the arterial wall, which may contribute to their antiatherosclerotic actions. Furthermore, some statins may have lower adverse drug interaction potential than others, which is an important determinant of safety during long-term therapy.
