Atorvastatin er en selektiv, kompetitiv HMG- CoA- reduktasehæmmer, det hastighedsbegrænsende enzym, som er ansvarlig for omdannelsen af 3- hydroxy- 3- methyl- glutaryl- coenzym A til mevalonat, et forstadium til sterol, herunder kolesterol.
Atorvastatin is a selective, competitive inhibitor of HMG-CoA reductase, the rate-limiting enzyme responsible for the conversion of 3-hydroxy-3-methyl-glutaryl-coenzyme A to mevalonate, a precursor of sterols, including cholesterol.
