The invention discloses a
cefepime dihydrochloride compound. The
cefepime dihydrochloride compound is prepared by a following method comprising the following steps: (1) dissolving a
cefepime dihydrochloride crude product into water and performing membrane separation and
impurity removal by selecting a separating membrane with the
molecular weight cut off of 500-3000; (2) adding the
impurity-removed solution into an
organic solvent, then adding
active carbon into the obtained solution, stirring, filtering the solution to remove
charcoal, and collecting the filter solution; (3) separating and purifying the filter solution with a
chromatographic column, wherein a mobile phase is a mixed
solvent of isopropanol and
acetonitrile, and a
stationary phase filler is
silica gel or aluminum
oxide; and (4) concentrating the separated and purified filter solution, and performing spray-
drying to obtain the cefepime dihydrochloride compound. The invention also discloses a pharmaceutical composition containing the cefepime dihydrochloride compound, wherein the pharmaceutical composition is sterile
powder for injection. The cefepime dihydrochloride compound and the pharmaceutical composition disclosed by the invention have low
impurity content and few toxic and side effects, so that the medication safety of the patient is greatly improved.
