Embodiment 1

[0018] The preparation of embodiment 1 pharmaceutical composition of the present invention

[0019] Take 5 g of fenbendazole, 18825 g of poloxamer, 0.15 g of sodium lauryl sulfate, 20.25 g of sorbitol, 10 g of PEG-6000, 0.5 g of simethicone, and 15 ml of distilled water. The preparation method is to first dissolve sorbitol, poloxamer 188, PEG-6000, sodium lauryl sulfate in boiling water, add simethicone and stir evenly, then add fenbendazole, and put it in a tank mixer Stir in the medium until it becomes granular, take it out, dry it, and pulverize it until it completely passes through a No. 9 sieve (75 μm) to obtain the fenbendazole dry emulsion.

Embodiment 2

[0020] The preparation of embodiment 2 pharmaceutical compositions of the present invention

[0021] Take 10 g of fenbendazole, 18825 g of poloxamer, 0.15 g of sodium lauryl sulfate, 20.25 g of sorbitol, 10 g of PEG-6000, 0.5 g of simethicone, and 15 ml of distilled water. The preparation method is to first dissolve sorbitol, poloxamer 188, PEG-6000, sodium lauryl sulfate in boiling water, add simethicone and stir evenly, then add fenbendazole, and put it in a tank mixer Stir in the medium until it becomes granular, take it out, dry it, and pulverize it until it completely passes through a No. 9 sieve (75 μm) to obtain the fenbendazole dry emulsion.

Embodiment 3

[0022] The preparation of embodiment 3 pharmaceutical composition of the present invention

[0023] Take 20 g of fenbendazole, 18825 g of poloxamer, 0.15 g of sodium lauryl sulfate, 20.25 g of sorbitol, 10 g of PEG-6000, 0.5 g of simethicone, and 15 ml of distilled water. The preparation method is to first dissolve sorbitol, poloxamer 188, PEG-6000, sodium lauryl sulfate in boiling water, add simethicone and stir evenly, then add fenbendazole, and put it in a tank mixer Stir in the medium until it becomes granular, take it out, dry it, and pulverize it until it completely passes through a No. 9 sieve (75 μm) to obtain the fenbendazole dry emulsion.

Abstract

The invention discloses a fenbendazole dry emulsion. The fenbendazole dry emulsion is prepared from, by weight, 5-30 parts of fenbendazole, 20-25 parts of emulgator, 10-25 parts of suspending agent, 20-25 parts of colloid protection agent, 0.05-0.25 part of surface active agent and 0.05-1 part of oil phase. It is indicated through a quality evaluation experiment that the fenbendazole dry emulsion 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 emulsion 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 tabl...
