Pitavastatin-d5 (sodium) is the deuterated form of Pitavastatin sodium. Pitavastatin (NK-104) sodium acts as a potent inhibitor of hydroxymethylglutaryl-CoA (HMG-CoA) reductase. In HepG2 cells, it inhibits cholesterol synthesis from acetate with an IC50 of 5.8 nM. Pitavastatin sodium is a highly effective inducer of hepatic low-density lipoprotein cholesterol (LDL-C) receptors.
