Atorvastatin calcium hydrate (Totalip) is a potent inhibitor of the HMG-CoA reductase . It is used as a potent hypolipidemic agent to reduce the elevated total-cholesterol, low-density lipoprotein (LDL), apolipoprotein B (apo B), and triglyceride (TG) levels, and to increase the high-density lipoprotein cholesterol (HDL-C) level in patients with primary hypercholesterolemia and mixed dyslipidemia.
