preparation example Construction

[0053] A preparation method of a compound antiparasitic preparation, comprising the following steps:

[0054] 1) Weighing and sieving: Weigh ivermectin, mebendazole, toltrazuril, disintegrants, fillers, lubricants, adhesives and other auxiliary materials according to the above parts by weight, and the weighed ivermectin Vermectin, mebendazole, toltrazuril and auxiliary materials are respectively pulverized and sieved through a 60-120 mesh sieve. Optionally, the adjuvant also includes a flavoring agent and a preservative, and the flavoring agent and the preservative are respectively weighed by the above parts by weight.

[0055] 2) Preparation of ivermectin solid dispersion: Add the sieved ivermectin to absolute ethanol to dissolve completely, then add part of the sieved filler and mix evenly, and then dry, pulverize and sieve , to prepare the ivermectin solid dispersion, wherein the content of the ivermectin in the ivermectin solid dispersion is 1%-5%.

Abstract

The invention relates to a compound anti-parasitic preparation, and a preparation method and application thereof. The compound anti-parasitic preparation is mainly prepared from the following raw materials in parts by weight: 0.04 to 0.1 part of ivermectin, 5 to 10 parts of mebendazole, 5 to 15 parts of toltrazuril, 3 to 10 parts of a disintegrating agent, 61 to 91 parts of a filling agent, 1 to 3parts of a lubricating agent and 0.3 to 1 part of an adhesive. The compound anti-parasitic preparation has high uniformity and has a good anti-parasitic effect.

Description

technical field [0001] The invention relates to the technical field of antiparasitic drugs, in particular to a compound antiparasitic preparation and a preparation method thereof. Background technique [0002] Along with the raising of economic capacity, more and more people keep dogs, cats etc. as pets. For example, dogs can not only add fun to people's ordinary life, but also relieve people's inner loneliness and pressure. However, dogs are mammals and are susceptible to parasitic diseases such as nematodes, tapeworms, and coccidiosis. If they cannot be treated in time, they will not only affect the health of dogs, but also increase the risk of human beings infected with parasitic diseases. In addition, since dogs and other mammals are also prone to cross-infection with bacterial parasites in daily life, and different bacterial parasites can infect each other, they will suffer from diseases of various etiologies. [0003] Ivermectin is a new type of low-toxic antibiotic ...
