Zusammenfassung:A stable, amorphous, lyophilized dihydrochloride salt of 7-( alpha -(2-aminothiazol-4-yl)- alpha -(Z)-methoxyiminoacetamido]-3-[(1-methyl-1-pyrrolidi nium)methyl]-3-cephem-4-carboxylate is described. This lyophilized salt is more easily prepared than the crystalline counterpart and can be reconstituted in effective concentrations for intramuscular and intravenous injection utilizing suitable organic and inorganic bases to pH 3-7.0.
