Problems solved by technology

[0004] Tiamulin fumarate has an unpleasant smell, which affects the compliance of animals to take medicine and brings great inconvenience to disease prevention and control
Commonly used soluble powders are more irritating. Some manufacturers use wet granulation technology to make them into granules in an attempt to reduce irritation. However, when the content of tiamulin fumarate is high, the viscosity of tiamulin fumarate is relatively high. Large, the prepared soft material is sticky, difficult to be extruded and rounded, and still has a certain pungent smell, so the conventional granulation method is not suitable for use

Abstract

The invention discloses tiamulin famarate soluble powder which is prepared by the following raw materials in parts by weight: 50-60 parts of tiamulin famarate, 20-30 parts of a pullulan polysaccharide-polyglutamic acid cross-linked polymer, 10-15 parts of garlic polysaccharide solid dispersion, 5-9 parts of soluble starch, 4-6 parts of sodium alginate, 2-3 parts of sodium tripolyphosphate, 1-1.6 parts of disodium ethylenediaminetetraacetate and 0.3-0.5 part of citric acid. The tiamulin famarate soluble powder disclosed by the invention is uniform in particle size distribution, stronger in high temperature and high humidity resistance and good in stability. The tiamulin famarate soluble powder is simple and efficient in preparation process, recyclable in used ethanol solvent, mature in recycling process, energy-saving, environment-friendly, suitable for industrial production and wide in application prospect.

Description

technical field [0001] The invention belongs to the field of veterinary drug preparations, and in particular relates to a soluble tiamulin fumarate powder. Background technique [0002] Tiamulin is also known as tiamulin, tiamulin, tiamulin, Zhiyuanjing, tiamulin, and tiamulin fumarate is mostly used in practice. Tiamulin is an animal-specific antibiotic. Its antibacterial effect is to inhibit the synthesis of susceptible bacterial proteins and act on the ribosomes in the bacteria. Tiamulin has special effects on a variety of Gram-positive bacteria and mycoplasma, especially on Staphylococcus aureus, streptococcus, various molds and some spirochetes. Tiamulin is used to prevent and treat diseases caused by mycoplasma infection, Escherichia coli, Salmonella, spirochete and other infections. It has special effects on swine mycoplasma pneumonia, Haemophilus pleuropneumonia, endemic pneumonia (asthma) and swine dysentery. It has good curative effect on mycoplasma arthritis, ac...
