Pravastatin sodium, USP is one of a class of lipid-lowering compounds, the statins, which reduce cholesterol biosynthesis. These agents are competitive inhibitors of HMG-CoA reductase, the enzyme catalyzing the early rate-limiting step in cholesterol biosynthesis, conversion of HMG-CoA to mevalonate. Pravastatin sodium, USP is designated chemically as 1-naphthaleneheptanoic acid, 1,2,6,7,8,8a-hexahydro-β,δ,6-trihydroxy-2-methyl-8-(2-methyl-1-oxobutoxy)-, monosodium salt, [1 S -[1α (β S *,δ S *),2α,6α,8β( R *),8aα]]-. It has the following structural formula: C 23 H 35 NaO 7 M.W. 446.52 Pravastatin sodium, USP is an odorless, white to off-white, fine or crystalline powder. It is a relatively polar hydrophilic compound with a partition coefficient (octanol/water) of 0.59 at a pH of 7. It is soluble in methanol and water (> 300 mg/mL), slightly soluble in isopropanol, and practically insoluble in acetone, acetonitrile, chloroform, and ether. Pravastatin Sodium Tablets USP are available for oral administration as 10 mg, 20 mg, and 40 mg tablets. Inactive ingredients include: calcium phosphate dibasic anhydrous, croscarmellose sodium, crospovidone, lactose anhydrous, microcrystalline cellulose, povidone and sodium stearyl fumarate.
