    摘要: New form of irbesartan having favourable chargeability is prepared from the alcoholic/etheric or ketonic solution of irbesartan after slow cooling with sporadic or light agitation and alternatively new crystalline form of an acid addition salt of irbesartan is prepared from the aqueous solution of a sodium salt of irbesartan after strongly acidifying aforesaid solution and subsequently adjusting pH with an alkali. Those are used in manufacturing a pharmaceutical composition.

    摘要: Present invention refers to the process of preparing amorphous atorvastatin calcium without intermediate isolation of crystal or undefined mixture of crystal and amorphous atorvastatin calcium, respectively. Forming of calcium atorvastatin salt is carried out in a mixture of chlorinated organic solvent or cyclic hydrocarbon solvent, respectively, the non-hydroxylic organic solvent, and water, the source of calcium ions is calcium acetate or calcium chloride, respectively.
