| titleOfInvention | PREPARATION OF A STABLE CEPHALOTHINE-SODIU M POWDER, FOR PARENTERAL ADMINISTRATION |
| abstract | The invention relates to a process for the preparation of substantially crystalline cephalothin-sodium for parenteral administration, in which a cephalothin-sodium solution is cooled from room temperature to -20 degrees C or preferably to -40 degrees C in 1 to 3 hours. in a mixture containing 2 to 10% of a C 1 -C3 alcohol or acetone, the remainder being water, then heated to a temperature of -3 degrees C to -10 degrees C for 3 hours or more, before cooling it again to -20 degrees C or preferably to -40 degrees C. Then a conventional freeze-drying operation is carried out. A stable, crystalline cephalothin-sodium powder which dissolves rapidly in acceptable pharmaceutical diluents in less than 24 hours. |
