Problems solved by technology

[0004] However, amoxicillin has poor solubility, slightly bitter taste, and low bioavailability
At present, the content of amoxicillin is mainly 10%. Due to the low concentration, poor stability, agglomeration and discoloration are easy to occur, and the shelf life is short, which seriously affects the use and efficacy.
The existing preparation method of amoxicillin soluble powder is only obtained by crushing and mixing. Amoxicillin has poor fluidity and is easy to absorb moisture, which is not conducive to the production and use of the product

Embodiment 1

[0017]

[0018] Preparation method: crush amoxicillin, sodium citrate, sodium dihydrogen phosphate, sodium alginate, and lactose in the prescribed amount and pass through an 80-mesh sieve. Granulate with a mesh sieve and dry at 60°C to obtain a high-content amoxicillin soluble powder.

Embodiment 2

[0020]

[0021]

[0022] Preparation method: Grind amoxicillin, sodium citrate, sodium dihydrogen phosphate, sodium alginate and lactose in the formula and pass through a 80-mesh sieve, mix evenly, add 75% ethanol and mix to make a soft material, pass through a 50-mesh sieve Granulate and dry at 60°C to obtain high-content amoxicillin soluble powder.

Embodiment 3

[0024]

[0025] Preparation method: Grind amoxicillin, sodium citrate, sodium dihydrogen phosphate, sodium alginate, and lactose in the formula and pass through an 80-mesh sieve in sequence, after mixing evenly, add 75% ethanol and mix to make a soft material, pass through a 50-mesh sieve Sieve and granulate, and dry at 60°C to obtain high-content amoxicillin soluble powder.

Abstract

The invention relates to high-amoxicillin-content soluble powder, and a preparation method and application thereof, and belongs to the field of a veterinary drug. The problem that an amoxicillin aqueous solution is low in dissolvability and poor in stability, which affects a therapeutic effect and application of the amoxicillin aqueous solution is solved. The powder comprises amoxicillin, a co-solvent, a stabilizing agent, a corrigent, and a soluble filler, and is used for treating porcine intestinal and respiratory tract infection due to bacteria such as escherichia coli and salmonella.

Description

Technical field: [0001] The invention belongs to the field of veterinary medicine, and relates to a high-content amoxicillin soluble powder, a preparation method and an application. Background technique: [0002] Amoxicillin, also known as amoxicillin, was first introduced to the market by BEECHAM in 1968. It is a semi-synthetic β-lactam antibiotic. Due to the β-lactam ring in its molecule Unstable, vulnerable to nucleophilic and electrophilic attacks, under the action of acids, alkalis, certain metal ions and oxidants, the β-lactam ring can be opened and molecular rearrangement can occur. Amoxicillin has a strong effect on Gram-negative bacteria such as Neisseria gonorrhoeae, influenza bacillus, pertussis bacilli, Escherichia coli, Brucella, etc., and is mainly used for infections of the urinary system, respiratory system, and biliary tract in human clinical practice. [0003] Amoxicillin is currently mainly used to treat poultry colibacillosis, salmonellosis, pasteurellos...
