    摘要: The present invention provides pravastatin sodium substantially free of pravastatin lactone and epiprava, the C-6 epimer of pravastatin. The present invention further provides a novel process for recovering pravastatin sodium from a fermentation broth in such high purity. The process includes the stages of forming an solution of the compound by extraction, obtaining an ammonium salt of pravastatin from the solution, purifying the ammonium salt of the compound and transposing the salt of the compound to pravastatin sodium.

    摘要: New polymorphic forms of pravastatin sodium are provided. Each of the new forms is selectively obtained by crystallization from different solvent systems, each solvent system having a protic component, and by controlling the rate of crystallization through temperature. The new polymorphic forms are suitable for use as active substances of pharmaceutical dosage forms for reduction of serum cholesterol levels in the bloodstream.
