Abstract

The invention discloses a fenbendazole dry suspension and a preparation method thereof. The fenbendazole dry suspension is prepared from, by weight, 50-80 parts of fenbendazole, 15-25 parts of emulgator, 10-25 parts of suspending agent, 10-25 parts of colloid protective agent and 0.05-0.25 part of surface active agent. It is indicated through a quality evaluation experiment that the fenbendazole dry suspension is low in settling velocity, good in physical stability, simple in preparation process, high in bath-to-batch quality stability and convenient to use and carry, the quality requirement of suspensions is met, and good application prospects are achieved.

Description

technical field [0001] The invention relates to a fenbendazole dry suspension and a preparation method thereof, belonging to the field of medicine. Background technique [0002] Fenbendazole is a benzimidazole anthelmintic widely used clinically. It not only has a high anthelmintic activity against gastrointestinal nematode adults and larvae, but also has a good effect on Dictyocaulus, Fasciola and tapeworms. It has a strong effect of killing insect eggs, and has been widely used in the prevention and treatment of gastrointestinal parasites in sheep, cattle, horses, pigs, dogs, cats and wild animals such as deer, ostriches, camels and other animals. [0003] Fenbendazole is white or off-white powder, odorless, tasteless, slightly soluble in methanol, insoluble in water, soluble in glacial acetic acid. Because fenbendazole has the physical and chemical properties of being insoluble in water and general organic solvents, its clinically commonly used dosage forms are mainly ta...
