The invention relates to the technical field of pharmaceutical preparations, in particular to a high-
dispersity nosiheptide preparation and a preparation method thereof. The high-
dispersity nosiheptide preparation is prepared from the following raw materials in parts by
mass: 1 to 5 parts of
nosiheptide, 1 to 3 parts of
sodium alginate, 2 to 4 parts of solubilizer, 1 to 2 parts of carboxyl-terminated polyamidoamine, 1 to 2 parts of dispersant, 5 to 15 parts of absolute ethyl
alcohol, 0.1 to 1 part of
nonionic surfactant, 0.1 to 0.5 part of L-
ascorbic acid, 0.1 to 0.5 part of
sodium thiosulfate and 1 to 2 parts of compound stabilizer. According to the method, the
solubility of nosiheptide is guaranteed, the risk of
organic solvent residue is reduced, the safety standard of modern
veterinary drugs is met, conventional production equipment can be adopted, raw materials are low in price and easy to obtain, industrial large-scale production can be achieved, and high economical efficiency and
operability are achieved.
