Unlike most others, however, it is a completely synthetic compound. Inhibition of the enzyme decreases de novo cholesterol synthesis, increasing expression of low-density lipoprotein receptors LDL receptors on hepatocytes.
Like other statins, atorvastatin also reduces blood levels of triglycerides and slightly increases levels of HDL-cholesterol. Recent studies have shown that in patients suffering from acute coronary syndrome , high-dose statin treatment may play a plaque-stabilizing role. At high doses, statins have anti-inflammatory effects, incite reduction of the necrotic plaque core, and improve endothelial function, leading to plaque stabilization and, sometimes, plaque regression.
However, there is an increased risk of statin-associated adverse effects with such high-dose statin treatment. It is the dosage of atorvastatin, rather than systemic medication concentration, which correlates with extent of LDL-C reduction.
