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-Naphthalene-heptanoic acid, 1,2,6,7,8,8a­hexahydro-β,δ,6-trihydroxy-2-methyl-8-(2-methyl-1-oxobutoxy)-,monosodium salt,[1S­ [1α(βS*,δS*),2α,6α,8β(R*),8aα]]-. Structural formula: Pravastatin sodium USP is an white to yellowish white, hygroscopic powder. It is a relatively polar hydrophilic compound with a partition coefficient (octanol/water) of 0.59 at a pH of 7.0. It is freely soluble in water, in methanol, soluble in alcohol, very slightly soluble in acetonitrile, practically insoluble in ether, in ethyl acetate, and in chloroform. Pravastatin sodium tablets USP are available for oral administration as 10 mg, 20 mg, 40 mg or 80 mg tablets. Inactive ingredients include: croscarmellose sodium, crospovidone, magnesium stearate, meglumine, microcelac 100 (lactose monohydrate and microcrystalline cellulose), microcrystalline cellulose, opadry white YS-1-7040 (hypromellose 2910, polyethylene glycol 8000, talc, and titanium dioxide).
