Abstract
The invention relates to virginiamycin soluble powder and a preparation method thereof, belonging to the technical field of medicines. The soluble powder is prepared from the following components in parts by weight: 0.01-20 parts of virginiamycin, 30-70 parts of polyethylene glycol-4000 and/or polyethylene glycol-6000, 1-10 parts of povidone K30, 0.5-2 parts of lauryl sodium sulfate and 1-10 parts of Fumei powder. The soluble powder provided by the invention is good in water solubility and uniform to dissolve, medicines are not separated out, and a water line is not blocked. Compared with the conventional manner of delivery by feed, the soluble powder is more convenient to use and provides a novel virginiamycin medication manner for the market. In addition, the medicine provided by the invention is good in stability and strong in operability of production processes, thereby facilitating market promotion.
Description
technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and relates to a virginiamycin soluble powder and a preparation method thereof. Background technique [0002] Virginmycin is a polypeptide antibiotic isolated from bacteria of the genus Streptomyces when Professor Dai Soma of the University of Lubang in Belgium conducted a screening test on soil. Its mechanism of action is to inhibit the ribosomes of Gram-positive bacteria to prevent bacterial protein synthesis and achieve bactericidal purposes. When the drug enters the intestinal tract of animals, it selectively kills intestinal bacteria, kills harmful bacteria and retains probiotics, reduces the consumption of nutrients by bacteria, reduces the production of harmful substances, slows down intestinal peristalsis, and feed stays in the intestinal tract The longer the time, the more complete the absorption of nutrients, thereby promoting the growth of animals. [0003] The ma...
