Abstract

The invention discloses a cefmetazole sodium powder for injection. The cefmetazole sodium powder for injection comprises: by weight, 1000 parts of cefmetazole sodium used as a raw material and 10-20 parts of L-lysine used as an auxiliary material. The power injection is prepared according to the following preparation method: firstly removing dust from the raw material and the auxiliary material, cleaning, wiping and sterilizing; respectively crushing cefmetazole sodium and L-lysine in a clean area of 100 level, and sieving through a sieve of 80 meshes; weighing and mixing according to a prescription, subpackaging into tube-type bottles after testing content qualified, pressing plugs, capping, carrying out lamp inspection, examining qualified, labeling and packaging. The cefmetazole sodiumpowder for injection in the prescription has stable performance to temperature and light. After 6 months of accelerated testing and 12 months of long-term sample storage for observation, contents of related substances are all less than 1%, and color, clarity, bacterial endotoxin and the like of the powder injection all accord with the pharmacopeial standard. The preparation method of the prescription has advantages of simple technology and stable and reliable quality.
