Abstract

The present invention discloses a composing prescription of a compound ivermectin injection and a preparation method of the compound ivermectin injection, and belongs to the veterinary medicine technology. The compound ivermectin injection comprises main drugs, a solvent and an antioxidant so as to prepare the stable high-concentration compound ivermectin injection. The injection has characteristics of advanced technology, good stability, broad spectrum, high efficiency, low irritation on the injected site, easy use, and clinical efficiency superior to the single-formula injection. According to the present invention, the raw materials comprise 0.5-5.0% of ivermectin, 2-20.0% of mebendazole, 0.5-5.0% of levamisole hydrochloride, 0.1-1% of the antioxidant, and the balance of the solvent, wherein the antioxidant is one or a mixture selected from thiourea, L-cysteamine hydrochloride, vitamin C, ethylenediamine, sodium hydrogen sulfite, anhydrous sodium sulfite, sodium formaldehydesulfoxylate dihydrate, sodium metabisulfite and the like, and the solvent is one or a mixture selected from propylene glycol, ethanol, glycerol, glycerol formal, dimethylformamide, dimethylacetamide, 2-pyrrolidone and the like.

Description

technical field [0001] The invention relates to a compound ivermectin injection and a preparation method thereof. Background technique [0002] Ivermectin: Ivermectin is a new type of broad-spectrum, high-efficiency, small dosage, and low-toxicity antibiotic antiparasitic drug. It has a good killing effect on internal and external parasites, especially nematodes and arthropods. , trematodes and protozoa (such as whipworms) are invalid. The repellent effect of ivermectin on nematodes and arthropods lies in increasing the release of the inhibitory transmitter γ-aminobutyric acid (GABA) in the worm body, opening the Cl ion channel controlled by glutamate, and enhancing the neuromembrane’s response to Cl. Permeability, thereby blocking the transmission of nerve signals, and eventually nerve paralysis, causing muscle cells to lose their ability to contract, resulting in the death of the worm. Ivermectin is widely used in gastrointestinal nematodes, lung nematodes and parasitic ...
