The decoquinate dry suspension can be easily accepted by patients.

Description

technical field [0001] The invention belongs to the field of veterinary drug preparations, and in particular relates to a decoquinate dry suspension and a preparation method thereof. Background technique [0002] Decoxyquinate is a new type of high-efficiency livestock and poultry special anticoccidial drug, and clinical data show that decoquinate has no great impact on the growth performance of livestock such as chickens, pigs, cattle and sheep, and is mainly used for cattle and goats , Sheep, chicken, pig coccidiosis control. It is the only chemical anticoccidial drug approved for use in the world, and it has no incompatibility with the veterinary drug feed additives currently allowed in China. [0003] Decoxyquinate is white or off-white crystalline powder, slightly soluble in ethanol, insoluble in water, and its preparation cannot be used after being dissolved in water, which affects its absorption and convenience after use, and brings restrictions to its application. ...
