Compound florfenicol soluble powder and preparation method thereof

The invention discloses compound florfenicol soluble powder. The compound florfenicol soluble powder is prepared from the following raw materials in parts by weight: 5 to 25 parts of florfenicol, 49 to 88 parts of a carrier, 6 to 23 parts of a cosolvent and 1 to 3 parts of a solubilizer, wherein the carrier is one or two of the combination of soluble starch, glucose and lactose; the cosolvent is one or two of acetamide and sodium succinate; and the solubilizer is lauryl sodium sulfate. According to the compound florfenicol soluble powder provided by the invention, the carrier can play a dispersion role, the lauryl sodium sulfate serves as a surface active agent for promoting dissolution, the acetamide and sodium succinate inside the water solution can be combined with florfenicol to form amolecular association compound salt, and then the purpose of solubilization is reached; and therefore, the compound florfenicol soluble powder provided by the invention is good in water solubility, the water solubility insid
