Abstract

The invention discloses compound sulfachlorpyridazine sodium powder and a preparation method thereof. The compound sulfachlorpyridazine sodium powder is prepared from the raw materials in parts by weight of 59-65 parts of sulfachlorpyridazine sodium, 11-13 parts of sulfanilamide synergist, 11-26 parts of inclusion compound, 1-2 parts of cosolvent and the balance filler. The compound sulfachlorpyridazine sodium powder is obtained by adopting an inclusion technology and spray drying. The inclusion compound is used after being dried for 8-12 hours, so that the inclusion space of the inclusion compound is increased, trimethoprim can be better included, the bad smell and bitter taste of trimethoprim are covered, the palatability of traditional compound sulfachlorpyridazine sodium powder is improved, the solubility of sulfachlorpyridazine sodium powder is increased, active ingredients are stably released, and the bioavailability is improved.

Description

technical field [0001] The invention relates to the technical field of veterinary medicine, in particular to a compound sulfachlordazine sodium powder and a preparation method thereof. Background technique [0002] The antibacterial spectrum of sulfachlordazine sodium is similar to that of sulfamethoxine, and it is the sulfa drug with the strongest antibacterial activity in vivo and in vitro. It has a wide antibacterial spectrum and a wide range of effects, and has a good inhibitory effect on most Gram-positive and Gram-negative bacteria. Clinically, it is mainly used for infectious diseases of Escherichia coli and Pasteurella in pigs and chickens. It also has a significant effect on coccidia, toxoplasma, leukocytozoa, etc. Bacteria are slow to develop drug resistance to running, maintain for a long time, have low blood drug concentration, and are not easy to produce crystallization urine and hematuria. [0003] With the emergence of antibacterial synergists such as trime...
