Abstract

The invention discloses a medicament for treating coccidiosis, particularly a novel compound anti-coccidiosis medicament and a preparation method thereof. The novel compound anti-coccidiosis medicament is characterized by being prepared from the following components: decoquinate, toltrazuril, polymer carrier, solubilizing agent and anhydrous dextrose. Therefore, the medicament has the advantages that: the indissoluble decoquinate and toltrazuril are prepared into water-soluble substances by using solid dispersion technology and inclusion technology, and the decoquinate and toltrazuril are mixed to fulfill the aim of reducing dosage, improving curative effect and reducing drug resistance; moreover, the synergistic effect of the medicaments can be realized by combining the decoquinate and the toltrazuril, the killing effect is enhanced and the dosage of each medicament is reduced by half.

Description

(1) Technical field [0001] The invention relates to a medicine for treating coccidiosis, in particular to a novel compound anticoccidial medicine and a preparation method thereof. (2) Background technology [0002] Coccidiosis is a parasitic disease that damages the intestinal tract of poultry and is caused by various parasites of the genus Eimeria, including Eimeria acuminata, Eimeria brucei, Eimeria giganta Coccidia, Eimeria tenella, Eimeria venom, Eimeria metamorphosis, etc. These parasites reproduce in the intestinal epithelial cells, destroy the integrity of the intestinal mucosa, and reduce the digestion and absorption capacity of the intestinal tract. Coccidiosis is responsible for 6% to 10% of poultry mortality and leads to reduced poultry growth rate and feed conversion efficiency, resulting in global economic losses of billions of dollars per year. At present, the prevention and treatment of coccidiosis is mainly based on drugs, and the use of chemical drugs is st...
