Statins are a competitive antagonists of HMG CoA, as they directly compete with the endogenous substrate for the active site cavity of HMGR. Statins are also noncompetitive with the cosubstrate NADPH (nicotinamide adenine dinucleotide phosphate). [5] By blocking the HMGR enzyme they inhibit the synthesis of cholesterol via the mevalonate pathway.
Statins appear to be effective at preventing cardiovascular disease and death in older adults, according to new research. Most clinical trials evaluating statins have not included people 75 and ...
A risk exists of muscle damage (myopathy and rhabdomyolysis) with statins. Hypercholesterolemia is not a risk factor for mortality in persons older than 70 years and risks from statin drugs are more increased after age 85. [2] Fibrates are indicated for hypertriglyceridemia. Fibrates typically lower triglycerides by 20% to 50%.
Researchers tested simvastatin, later sold by Merck as Zocor, on 4,444 patients with high cholesterol and heart disease. After five years, the study concluded the patients saw a 35% reduction in their cholesterol, and their chances of dying of a heart attack were reduced by 42%. [12] [192] In 1995, Zocor and Mevacor both made Merck over US$1 ...

In 1994, the findings of a Merck-funded study were published in The Lancet concluding the efficacy of statins in lowering cholesterol proving for the first time not only that a "statin reduced 'bad' LDL cholesterol but also that it led to a sharp drop in fatal heart attacks among people with heart disease." [112] [116]
Over the dose range of 1 to 80 mg/day strong linear dose‐related effects were found; total cholesterol was reduced by 22.1% to 44.8%, LDL cholesterol by 31.2% to 61.2%, non-HDL cholesterol by 28.9% to 56.7% and triglycerides by 14.4% to 26.6%.
Statins are the typically used medications, in addition to healthy lifestyle interventions. [68] Statins can reduce total cholesterol by about 50% in the majority of people, [39] and are effective in reducing the risk of cardiovascular disease in both people with [69] and without pre-existing cardiovascular disease.
