Application of Atorvastatin calcium
1. Hypercholesterolemia
patients with primary hypercholesterolemia. Including patients with familial hypercholesterolemia (heterozygous type) or mixed hyperlipidemia (equivalent to types IIa and IIb of Fredrickson classification), if the effect of dietary therapy and other non-drug treatments is not satisfactory, the application of this product can be treated It has elevated total cholesterol (TC), elevated low-density lipoprotein cholesterol (LDL-C), elevated apolipoprotein B (Apo B), and elevated triglycerides (TG).
