Abstract

The invention discloses a formulation and a preparation method of an amoxicillin superfine powder water-soluble preparation and belongs to the technical field of veterinary medicine preparation. The amoxicillin superfine powder water-soluble preparation is soluble powder and comprises, by mass, 15-35% of amoxicillin, 15-35% of PVPK30, 15-35% of PEG6000, 5-20% of L-arginine and 1-5% of Tween-80. The amoxicillin superfine powder water-soluble preparation is non-degradable, specific surface area is increased, the preparation can be dispersed well and is easier to absorb, dissolution rate of amoxicillin is increased greatly, and the preparation is low in water content and impurity content. Acceleration experiments and long-time experiments show that the preparation has high stability. Pharmacological experiments find that the preparation has treatment effect on chicken salpingitis obviously better than common amoxicillin soluble powder, healing rate reaches 85.3%, and effective rate reaches 91.0%.

Description

technical field [0001] The invention belongs to the technical field of veterinary medicine, and in particular relates to a formula of amoxicillin superfine powder water-soluble preparation and a preparation method thereof. Background technique [0002] In recent years, the abuse of antibiotics is very common, and the problem of bacterial resistance is becoming more and more serious. In order to treat animals, antibiotics usually need to be increased several times to achieve a certain effect. The use of large doses of antibiotics leads to the inability of drugs to be metabolized in animals. It is excreted, causing secondary pollution to water sources, soil and other environments. In order to prevent and control animal diseases, promote the healthy development of the breeding industry, maintain human health, and minimize the excretion of drug residues. Clinically, there is an urgent need to supplement or replace antibacterial drugs with less dosage, fast drug metabolism, defi...
