Abstract

PURPOSE: To prepare the title injection which is extremely stable even in the presence of moisture, and easily reconstituted by dissolving in water before use, by packing a novel cephalosporin-type antibiotic substance SM(H) together with a basic substance in the form of powders in an ampule.
CONSTITUTION: The title injection agent is prepared by packing a novel antibiotic substance D-7-[α-(4-hydroxy-6-methylnicotinamio)-4-hydroxy-phenyl-acetamido]-3- -(1-methyltetrazol-5-yl)thiomethyl-Δ3-cephem-4-carboxylic acid [hereinafter called SM(H)] and a basic substance especially Na2CO3 in the form of powders in an ampule. The molar ratio of SM(H) and Na2CO3 is pref. 1:0.6W1.5. A freeze-dried injection of a water soluble salt of S(M)H is rather unstable, however, the title injection is stable even in the presence of 4W5% of moisture.
