| titleOfInvention | PROCEDURE FOR OBTAINING PRAVASTATIN SODIUM PURIFIED. |
| abstract | Procedure for obtaining pravastatinnpurified sodiumn n n Simple, fast, economical andneasy industrial scaling, to obtain pravastatin sodiumnpurified from a fermentation broth, which comprises thenformation of an enriched aqueous solution of pravastatin, thenobtaining and isolation of pravastatin sodium or rawnpravastatin calcium and conversion to pravastatin sodiumnpurified by suspension in water, adjust to acidic pH,nextraction with organic solvent such as ethyl acetate or methylnisobutyl ketone, adding a solution of acid sodium saltncarboxylic acid in low molecular weight alcohol, such as octanoatensodium in methanol and isolation of purified sodium pravastatinnby filtration, allowing to obtain a quality final productnpharmaceutical optionally applying a recrystallization processnto the purified pravastatin sodium obtained. |
