Abstract

"MéTODO PARA PRODUZIR UMA FORMA SóLIDA DE HEPARINA". A presente invenção fornece um novo método para processar uma solução que contém heparina; sais de heparina ou complexos de heparina em um solvente ou em uma mistura de solventes, para formar produtos sólidos de heparina, caracterizado pela utilização de um tambor de secagem à pressão atmosférica ou sob vácuo e em uma temperatura de secagem adequada."METHOD FOR PRODUCING A SOLID FORM OF HEPARIN". The present invention provides a novel method for processing a solution containing heparin; Heparin salts or heparin complexes in a solvent or a mixture of solvents to form heparin solids, characterized by the use of a drying drum at atmospheric pressure or under vacuum and at a suitable drying temperature.
