Rosuvastatin-d₆is intended for use as an internal standard for the quantification of rosuvastatin by GC- or LC-MS. Rosuvastatin is an HMG-CoA reductase inhibitor (IC₅₀= 5 nM).^1,2It is a fully-synthetic inhibitor that is designed to maximize the points of contact with, and inhibition of, HMG-CoA reductase.¹Formulations containing rosuvastatin reduce low-density lipoprotein and C-reactive protein and increase high-density lipoprotein in humans.^3,4
