We conducted a post hoc pharmacoeconomic analysis of a multicenter, open-label, randomized, parallel-group, 8-week efficacy-safety comparison of five HMG-CoA reductase inhibitors-atorvastatin, fluvastatin, lovastatin, pravastatin, and simvastatin. The 534 patients requiring cholesterol-lowering therapy took the drugs for 8 weeks with 15 different regimens. Low-density lipoprotein (LDL) was meas...

Endothelial dysfunction is an early event in atherogenesis and is associated with the propensity to cause future cardiovascular events. The amelioration of endothelial dysfunction has been a research target for some years now, and success has been reported with, for example, the 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors. Research has also identified the homozygous del...

Hydroxy-methyl-glutaryl-coenzyme A (HMG-CoA) reductase inhibitors or statins are well tolerated, but associated with various statin-associated symptoms (SAS), including statin-associated muscle symptoms (SAMS), diabetes mellitus (DM), and central nervous system complaints. These are "statin-associated symptoms" because they are rare in clinical trials, making their causative relationship to sta...

HMG-CoA (3-hydroxy-3-methylglutaryl-coenzyme A) reductase (HMGR) catalyzes the committed step in cholesterol biosynthesis. Statins are HMGR inhibitors with inhibition constant values in the nanomolar range that effectively lower serum cholesterol levels and are widely prescribed in the treatment of hypercholesterolemia. We have determined structures of the catalytic portion of human HMGR comple...

In skin fibroblasts grown from four children with a homozygous form of type II hyperlipoproteinemia, the feedback control of sterol synthesis and the inhibitory effect on hydroxymethylglutaryl (HMG) CoA reductase activity by serum or low density lipoprotein were present, though diminished compared with the effects in normal fibroblasts. Stimulation of HMG CoA reductase by insulin and inhibition...
