Ezetimibe/Simvastatin: a review of its use in the management of hypercholesterolemia. [Journal Article, Review]
Am J Cardiovasc Drugs 2004; 4(6):405-22.
Ezetimibe/simvastatin (Inegy, Vytorin) therapy combines two lipid-lowering compounds with complementary mechanisms of action, thereby blocking the two sources of plasma cholesterol and improving lipid profiles. Thus, intestinal absorption of dietary cholesterol and related phytosterols is blocked by ezetimibe, with the biosynthesis of cholesterol in the liver inhibited by simvastatin.Developing management trends for primary hypercholesterolemia include the aggressive reduction of low-density lipoprotein cholesterol (LDL-C) to goals lower than previously considered appropriate, the targeting of lipid subfractions and atherogenic indices other than LDL-C alone, and the broader use of combination lipid-lowering therapy. In line with these trends, ezetimibe/simvastatin is an effective and generally well tolerated adjunct to dietary therapy for markedly reducing LDL-C levels, providing a 52% reduction with the recommended starting dosage. Furthermore, ezetimibe/simvastatin is formulated with variable doses of simvastatin (i.e. 10/10 mg, 10/20 mg, 10/40 mg, and 10/80 mg) and hence, the dosage may be adjusted to suit the individual patient's needs. As longer-term efficacy, tolerability, economic and outcome data accrue, ezetimibe/simvastatin will be positioned more definitively relative to existing and emerging lipid-lowering treatments. Currently, ezetimibe/simvastatin therapy represents a valuable novel option for the management of primary hypercholesterolemia across diverse patient populations and as an adjunct to other lipid-lowering treatments in those with homozygous familial hypercholesterolemia.
