Abstract

The invention discloses antimicrobial peptide effervescent tablets, which comprise the following components by weight percent: 5-20% of cecropin antimicrobial peptide, 21% of tartaric acid, 15-32% of sodium bicarbonate, 4% of polyvinylpyrrolidone, 25.5-40.5 of starch, and 0.5% of magnesium stearate. The invention also discloses a preparation method of the antimicrobial peptide effervescent tablets and application thereof in treating hysteritis in milk cattle. The antimicrobial peptide effervescent tablets disclosed by the invention use cecropin antimicrobial peptide as a raw material, and have the following advantages: (1) the raw materials are commonly used and easily available, so as to save cost; (2) the process route is simple, so as to be favor of production; (3) due to unique disintegration manner, large contact surface, sustained release and other characteristics, the effervescent tablets for treating hysteritis in milk cattle are suitable for uterus drug delivery, so as to effectively increase drug concentration, improve antimicrobial effect and improve clinical cure rate; and (4) the tablets are convenient to carry and simple in administration, and have rapid action, good stability and other advantages.

Description

technical field [0001] The invention relates to the field of veterinary medicine, in particular to an antimicrobial peptide effervescent tablet and a preparation method and application thereof. Background technique [0002] Cow endometritis is the most common obstetric disease in dairy cows. The morbidity of affected cows is very high, and the course of the disease is long, which seriously affects the milk production and milk quality of dairy cows, and causes serious economic losses to the dairy industry. According to reports, the economic loss caused by cow infertility in the United States is nearly 250 million U.S. dollars every year. It is reported in the UK that endometritis accounts for about 95% of infertile cows, and the incidence of endometritis in cows reported by the former Soviet Union is 34.9%. 39.8%, the incidence of endometritis in dairy cows in my country accounts for 20% to 35%. From 1983 to 1985, the results of a survey of 41 dairy farms in 16 cities includ...
