Abstract

The present invention relates to a long-acting flunixin meglumine injection for animals and method for preparing same. The invention provided flunixin meglumine injection delays medicine absorption so as to prolong medicine action time by adding proper polyvinylpyrrolidone and poloxamer high molecular compound in the preparation process. Approved by clinical experiments that action time of the invention is longer than common flunixin meglumine injection, the invention reduces labor strength and reduces stress response of animals with more obvious medicine effect, and capable of using with long-acting antibacterials to provide a synergistic effect. The invention provides a animals specific medicine of long-acting, effective antipyretic, antiphlogosis and analgesic for veterinary clinical.

Description

technical field [0001] The invention belongs to the technical field of veterinary preparations, and relates to a long-acting flunixin meglumine injection and a preparation method thereof. Background technique [0002] Schering-Plough Corporation of the United States launched a non-steroidal drug for animals - flunixin meglumine (flunixin meglumine) at the end of the last century. It has a unique structure and is a cyclooxygenase inhibitor. The production of prostaglandins can effectively prevent Escherichia coli endotoxin from increasing the bronchial exudate in respiratory diseases, and the accumulation of neutrophils and albumin in the exudate. It is a very effective anti-inflammatory and anti-inflammatory agent. Pain, antiendotoxin and antipyretic NSAIDs. [0003] Because livestock and poultry are attacked by bacteria, viruses, and mycoplasma, most of the clinical symptoms are accompanied by inflammatory symptoms (fever, pain), which affect the normal diet, activities an...
