Abstract

The invention provides a method for preparing water-soluble florfenicol powder, wherein the steps of the method are as follows: step (1) taking florfenicol, β-cyclodextrin and an absorption accelerator, and mixing them in a mixer 5min, make a physical mixture, the mass ratio of each component is as follows: florfenicol 10~30w / w%, β-cyclodextrin 69.5~89.5w / w%, absorption accelerator 0.5w / w%; Step (2) The physical mixture obtained in the step (1) is put into a vibration pulverizer and pulverized to obtain water-soluble florfenicol powder. The invention also provides the water-soluble florfenicol powder prepared by the method, the maximum solubility of florfenicol is 10000mg / L, which is equivalent to 200 times of the clinical concentration, and can realize the drinking water administration of the farm.

Description

technical field [0001] The invention belongs to the field of veterinary medicine, in particular to a preparation method of water-soluble florfenicol powder and the prepared water-soluble florfenicol powder. Background technique [0002] Florfenicol (Florfenico1), also known as florfenicol, is the fluoride of thiamphenicol, which belongs to the broad-spectrum antibiotics of chloramphenicol for animals. It is developed by Schering-Plough Company of the United States. Chloramphenicol is similar to thiamphenicol, but its antibacterial activity is significantly better than that of chloramphenicol, and it has no side effects of aplastic anemia, and does not form cross-resistance with humans, so it has a wide range of clinical applications and is used for the treatment of Respiratory tract infection, typhoid fever, intestinal infection, etc. However, due to the poor water solubility of florfenicol, the dosage method is limited in clinical application, especially in large-scale int...
