Production method of enteric-coated kitasamycin for feed
ActiveCN101611766AProtect weak alkaline antibioticsProlong the action timeAnimal feeding stuffAccessory food factorsAcrylic resinMicroparticle
The invention discloses a production method of enteric-coated kitasamycin for feed, which comprises the following process steps: step one, the preparation of drug-loaded pellets; step two, inner layer sustained-release coating of the drug-loaded pellets, which prolongs the release and acting time of kitasamycin; and steps three, outer layer enteric coating of the drug-loaded pellets, which ensures the release in succus entericus and small or no release in gastric juice. The method has the advantages that the kitasamycin is subjected to pellets pelletizing and 99 percent of the prepared granulums can pass through 24 meshes, so the dust is greatly reduced and the fluidity is increased; the coating of the inner layer sustained-release agent (HPMC) prolongs the release and acting time of the kitasamycin, reduces medication times and reduces the medication cost; and a layer of enteric substance, namely acrylic resin-III is sprayed and coated on the outer layer of particles. The substance protects the kitasamycin which is a weakly alkaline antibiotic from being damaged by gastroc acid in stomach, quickly disintegrates after entering enteric canal and releases the kitasamycin; and then the kitasamycin is absorbed by gastrointestinal mucosa into blood drug to play a role of restraining the reproduction of pathogenic microorganism and preventing diarrhea. Insoluble in the stomach, kitasamycin coating formulations have no pessimal stimulation on the stomach, and cannot result in regurgitation and vomiting. In addition, the sustained-release formulation, namely the kitasamycin prolongs the acting time so the medication times is reduced, the medication cost of farmers is reduced, and the economic benefit is improved.
