Abstract

The invention relates to an albendazole suspension containing ivermectin nanoemulsion, which is characterized by comprising the following components in parts by weight: 1-30 parts of albendazole, 0.01-1 part of ivermectin, 1-10 parts of oil phase, 1-20 parts of cosurfactant, 1-25 parts of dispersant (emulsifier), 0.01-10 parts of suspending agent, 0.01-10 parts of thickening agent and 0.1-10 parts of preservative. The invention ingeniously uses the oil phase of the ivermectin nanoemulsion as a wetting agent for wetting albendazole, thereby reducing the consumption of the surfactant and solvent, enhancing the safety of the preparation and greatly lowering the cost of the preparation.

Description

technical field [0001] The invention belongs to the field of preparation of veterinary medicine preparations, and relates to a medicine for treating internal and external parasitic diseases of livestock, an albendazole suspension containing ivermectin nanoemulsion and a preparation method thereof. Background technique [0002] The deworming effects of Albendazole and Ivermectin have been fully affirmed by the industry after years of clinical application. However, since the anthelmintic spectrum of these two drugs has its own emphasis, this brings a lot of inconvenience to the clinical application of veterinary medicine. For example, albendazole has a wide deworming spectrum for endoparasites in animals, but is ineffective for ectoparasites. Ivermectin has a wide deworming spectrum against ectoparasites, and is also effective against some internal parasites (mainly nematodes), but it is ineffective against tapeworms and trematodes. [0003] For this reason, someone prepared...
