Embodiment 1

[0023] The warnemulin hydrochloride granules are made of warnemulin hydrochloride as the main ingredient and appropriate amount of filler and wetting agent by weight percentage.

[0024] formula:

[0025] Warnemulin Hydrochloride 10%

[0026] Round porous sucrose pellets 1%

[0027] Distilled water 89%.

[0028] production method

[0029] Dissolving the warnemulin hydrochloride with distilled water first, then adding round porous sucrose pellets and stirring until uniformly mixed to obtain the warnemulin hydrochloride granules.

[0030] Because warnemulin hydrochloride itself has great peculiar smell and instability, the present invention makes it into granules to overcome the peculiar smell of warnemulin hydrochloride and increase its stability. Dosage form, the present invention increases the dosage form of the same medicine, makes administration more diverse, and satisfies the deficiency of the market. The warnemulin hydrochloride granule of the present invention has t...

Abstract

The invention discloses a valnemulin hydrochloride granule which comprises the following raw materials by weight: 10% of valnemulin hydrochloride, 89% of fillers, and 1% of wetting agents. The invention also discloses a preparation method of the valnemulin hydrochloride granule. Since valnemulin hydrochloride itself has heavy peculiar smell and is unstable, the invention prepares granules to overcome the peculiar smell of valnemulin hydrochloride, and improves the stability; no dosage form administrated in a granule form is on the market; the invention introduces a dosage form of a same medicament, makes the administration become more diverse, and meets the deficiency in the market. The valnemulin hydrochloride granule of the invention has the advantages of fast absorption, quick effect, capability of overcoming the deficiencies of former dosage forms, convenience, stability, and good taste.

Description

technical field [0001] The invention belongs to the field of veterinary drug antibiotics, in particular to warnemulin hydrochloride granules and a preparation method thereof. Background technique [0002] Valnemulin hydrochloride (also known as fluvonimulin, Valnemulin), the chemical name is ((2-((R)-2-amino-3-methylbutyrylamino)-1,1-dimethylethyl group) mercapto) acetic acid, (3aS, 4R, 5S, 6S, 8R, 9R, 9aR, 10R)-octahydro-5,8-dihydroxy-4,6,9,10-tetramethyl-6-vinyl - 3a,9-Propane-3aH-cyclopentacyclooctene-1(4H)-one-8-ester. Vernimulin is a new generation of pleuromutilin semi-synthetic antibiotics. It belongs to the diterpene class and belongs to the same class of drugs as tiamulin. It is a special antibiotic for animals. It is mainly used to prevent mycoplasma disease and Gram-positive bacterial infection in pigs, cattle, sheep and poultry.
