[HMG-CoA reductase inhibitors: a brief review of their pharmacological properties and clinical efficacy in cardiovascular disease].

The results of recently published studies on primary and secondary prevention of coronary heart disease with HMG-CoA reductase inhibitors--statins--support their use in patients with primary hypercholesterolaemia or mixed hyperlipidaemia, with or without atherosclerotic vascular disease. From a pharmacological point of view, statins inhibit HMG-CoA reductase, reduce the endogenous synthesis of cholesterol and increase the apoB/apoE lipoprotein clearance from plasma. Recent studies confirm that HMG-CoA reductase inhibitors may also decrease hepatic production of VLDL and LDL-cholesterol. However, they have different pharmacokinetic properties and variable effectiveness with potential clinical implications. These drugs are generally well tolerated with a similar profile of adverse effects (gastrointestinal effects, hepatic dysfunction and myopathy). The knowledge of their pharmacodynamic and pharmacokinetic properties can lead to a rational use and greater understanding of their potential benefits.
