Abstract
The invention provides wettable fenbendazoleivermectinpowder which is prepared from the following raw materials and auxiliary materials in parts by weight: 2.5-10 parts of fenbendazole, 0.1-0.8 part of ivermectin, 0.5-3 parts of magnesiumstearate, 43.9-74 parts of powdered sugar, 3-11 parts of sodiumdodecyl sulfate, 0-8 parts of xanthan gum, 0.6-1 part of fresh milk essence, 0.6-1 part of saccharinsodium and 10-30 parts of sodium citrate. The invention also provides a preparation method and application of the wettable fenbendazoleivermectinpowder. The wettable fenbendazole ivermectin powder significantly improves the dispersity of the ivermectin and fenbendazole in water to ensure that the ivermectin and the fenbendazole can be uniformly distributed in the water for a long time to facilitate clinical water drinking and administration; and wettable fenbendazole ivermectin powder has a food calling function, namely that the fenbendazole ivermectin powder has a food calling function when used on faunas with sensitive tastes, such as pigs and the like. The wettable fenbendazole ivermectin powder is simple in preparation process, low in production cost and suitable for industrial large-scale production.
Description
technical field [0001] The invention relates to a wettable fenbendazole ivermectin powder and a preparation method and application thereof. Background technique [0002] Since the 1940s, the research and development of anthelmintics has been extremely hot, during which gratifying results have been achieved; especially the discovery of Avermectins in 1976 opened a new era of anthelmintic research . The compound has a very strong repelling effect on nematodes and arthropods parasitic on animals, so that the dosage of anti-helminth drugs can be reduced from mg / kg level to μg / kg level. Currently commercialized drugs in this category include Avermectin (AVM), Ivermectin (IVM), Doramectin (DRM), and Eprinomectin (Eprinomectin, EPM, also known as iplemectin, apremectin), selamectin (Selamectin, SLM) and moxidectin (Moxidectin or Milbemycin, MXD, also known as moxidectin, moxidectin) and so on. Due to its excellent anthelmintic activity and high safety, abamectins are regarded as...
