General description

Atorvastatin calcium salt trihydrate is an anti-hyperlipoproteinemic and a synthetic cholesterol-reducing agent. It is a crystalline powder.


Atorvastatin calcium salt trihydrate has been used:
• as an inhibitor of β-Hydroxy β-methylglutaryl-CoA (HMG-CoA) reductase in HepG2 cells
• to investigate its anticancer functionality in human cell lines
• in the preparation of atorvastatin poly(lactic-co-glycolic acid) biosphere for tissue engineering studies


5, 25 mg in glass bottle

Biochem/physiol Actions

Atorvastatin calcium salt trihydrate is a specific inhibitor of HMG-CoA reductase. HMG-CoA reductase is the enzyme that catalyzes the conversion of HMG-CoA to mevalonate, an early step in cholesterol biosynthesis. Atorvastatin is used in the treatment of hypercholesterolemia.
