Embodiment 1

[0018] The preparation of embodiment 1 paste of the present invention

[0019] Prescription composition:

[0020]

[0021] Preparation:

[0022] (1) Take the prescribed amount of glycerol and add ethylparaben, heat it on a water bath to 50-60°C to melt it, then add an appropriate amount of water, add enrofloxacin, sodium hydroxide, and powdered sugar and stir to dissolve . (2) Heat liquid paraffin, lanolin, and vaseline on a water bath to about 50°C. Then pour (1) into (2), stir and add water to the full amount, stir evenly until cooled, divide into packages, 5g per package.

Abstract

The invention provides an enrofloxacin cataplasm which is prepared from raw material medicines and auxiliary materials in parts by weight: 2.5-7.5 parts of enrofloxacin, 1-3 parts of ethylparaben, 15-20 parts of glycerol, 60-100 parts of powdered sugar, 30-70 parts of liquid paraffin, 100-130 parts of wool fat, 180-200 parts of vaseline and 0-40 parts of octadecanol. The invention further provides a preparation method and use of the enrofloxacin cataplasm. The cataplasm is adopted to be attached to the palate of a piglet, the piglet can swallow automatically and the cataplasm is not easy to spit out, so that the piglet is prevented from being irritated, the growth of the piglet is not affected, and the cataplasm is convenient to feed. The cataplasm is stable in quality, and the maintaining time of blood concentration in vivo is longer. The cataplasm is slowly eliminated and the effect is prolonged, and the plasma medicine peak concentration is relatively slow to the benefit of reducing the toxic and side effects, so that the cataplasm is safer and more reliable to use.

Description

technical field [0001] The invention relates to a paste for treating diarrhea of ​​piglets, a preparation method and application thereof. Background technique [0002] Enrofloxacin is also known as ethyl ciprofloxacin and enrofloxacin. Systematic name: 1-cyclopropyl-7-(4-ethyl-1-piperazinyl)-6-fluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylic acid. This product is currently designated as an animal-specific drug by the state. It has a long half-life in animals and good tissue distribution. It is a broad-spectrum bactericidal drug and has special effects on mycoplasma. It has bactericidal effect on Escherichia coli, Klebsiella, Salmonella, Proteus, Pseudomonas aeruginosa, Haemophilus, Pasteurella multocida, Pasteurella hemolyticus, Staphylococcus aureus, Streptococcus, etc. After ingestion by animals, not only will it remain in livestock and poultry products, but the drug will enter the ecological environment from feces, urine and other excreta in the form of prototype compoun...
