Abstract

The invention discloses a formula of veterinary chlortetracycline hydrochloride soluble powder and a preparation method thereof. The soluble powder is prepared from the following components in percentage by weight: 10-50 percent of chlortetracycline hydrochloride, 0.2-3.0 percent of sodium dodecyl sulfate, 0.1-1.0 percent of ethylenediamine tetraacetic acid disodium salt and the balance of glucosum anhydricum. The chlortetracycline hydrochloride is utilized as a raw material, sodium dodecyl sulfate is added as an absorption enhancer, and ethylenediamine tetraacetic acid disodium salt is utilized as an antioxidant and a chelating agent, so that the stability and high efficiency of chlortetracycline hydrochloride soluble powder are ensured.

Description

technical field [0001] The invention relates to a veterinary aureomycin hydrochloride soluble powder formula and a preparation method thereof, belonging to the technical field of veterinary drug preparation. Background technique [0002] At present, chlortetracycline hydrochloride soluble powder in the market, because chlortetracycline is unstable, easy to oxidize and change color, has a great influence on the stability and therapeutic effect of the preparation. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides veterinary aureomycin hydrochloride soluble powder formula and preparation method thereof, which can promote drug absorption and reduce Ca 2+ , Mg 2+ The interference effect of metal ions on the absorption of chlortetracycline can improve the absorption rate and bioavailability of the main drug of chlortetracycline. [0004] In order to achieve the above object, a stable and efficien...
