Abstract

The invention relates to a method for preparing ceftiofur hydrochloride parenteral solution; the hydrochloride parenteral solution has the characteristics of even distribution and clear and transparent solution. The method comprises the following steps: (1) adding propylene glycol and ceftiofur hydrochloride with a volume equal to 60-70% of the total volume of ceftiofur hydrochloride parenteral solution to be prepared in a thick mixing tank; adding 2-10g ceftiofur hydrochloride for every 100ml of total volume of the ceftiofur hydrochloride parenteral solution; heating to 40-50 DEG C and stirring for rapid dissolving; (2) adding propylene glycol to reach the total volume of the ceftiofur hydrochloride parenteral solution to be prepared and cooling to 20-30 DEG C; (3) adding active carbon, stirring for 15-20 minutes and filtering; and (4) filling and sealing, sterilizing, light check and packing. The invention solves the problems of difficult and uneven injection of the ceftiofur hydrochloride parenteral solution of the existing technology and makes up the defects of easy-layer and inconvenient use of the ceftiofur hydrochloride suspension injection of the existing technology.

Description

technical field [0001] The invention relates to a preparation method of ceftiofur hydrochloride injection, in particular to a preparation method of uniformly distributed, clear and transparent ceftiofur hydrochloride injection. Background technique [0002] Porcine contagious pleuropneumonia is a respiratory infectious disease caused by Actinobacillus pleuropneumoniae. Acute and subacute cases are mainly characterized by fibrinous hemorrhagic pleuropneumonia, and chronic cases are mainly characterized by fibrinous necrotizing pleuropneumonia. In the past 20 years, the disease has been increasing year by year in the world, and has become one of the main infectious diseases of pigs, which has brought huge losses to the breeding industry. Ceftiofur hydrochloride has a strong antibacterial effect on most Gram-negative and positive bacteria. It is effective against diseases caused by various pathogens such as Pasta bacillus multocida, Paste bacillus haemolytica, Actinobacillus p...
