Abstract

The invention discloses a formula of an antimicrobial oil emulsion microcapsule for veterinary use, wherein per 1000g of the antimicrobial oil emulsion microcapsule contains 50-100g of an antimicrobial agent, 250-500ml of oil for injection, 250-500ml of water for injection, 1-5g of PEG, 5-10ml of sorbitan fatty acid ester, 5-10ml of polyoxyethylene sorbitan fatty acid ester, 250-500g of soluble starch, and 50-100g of methyl cellulose. According to the present invention, the oil emulsion is developed to be microcapsules which can be used for oral administration, thereby maintaining the long-acting and sustained-release effects of the oil emulsion, while in a large extent preventing disadvantages and side reactions in the production and application of the oil emulsion. The preparation process of the microcapsules is relatively simple, reducing the use of organic solvents and thereby reducing the cost of the product.

Description

technical field [0001] The present invention relates to the creation of a new dosage form of veterinary antibacterial drugs, in particular to the microcapsule coating agent of oil emulsion of veterinary antibacterial drugs, so that the oil emulsion of antibacterial drugs can be administered orally, thereby forming a new way of oral administration of long-acting preparations, The invention also relates to the preparation method and clinical application of the dosage form. Background technique [0002] At present, in the field of veterinary pharmacy, especially in the field of antibacterial pharmacy, the commonly used dosage forms are several conventional dosage forms such as powder, premix, ordinary water injection, tablet and granule. Such preparations play an important role in controlling animal diseases. played an important role. However, in recent years, animal husbandry diseases have been spreading all over the world, and a vicious cycle of mixed infections has emerged....
