Ivermectin is a novel and highly effective semi-synthetic antibiotic insecticide, acaricide, nematocide, insect nerve agent, biological osmotic agent. The mechanism of action is to interfere with the neurophysiological activities of pests, stimulate the release of γ -aminobutyric acid, act on nerve and muscle joints, increase the release of chloride ions, inhibit the information transmission of nerve joints, resulting in paralysis and poisoning death of pests and mites. The product is a colorless or light brownish yellow liquid. Ivermectin is a novel antibiotic antiparasitic drug with broad spectrum, high efficiency and low toxicity. It has good repellent effect on both internal and external parasites, especially nematodes and arthropods. But not to tapeworms, trematode and protozoa. Large ring lactone class parasite drug resistance to nematodes and the function of flooding killed by arthropods, is to increase the insect body inhibitory neurotransmitter gamma aminobutyric acid (GABA) release, and open the glutamic acid control Cl ion channels, strengthen the nerve membrane permeability of Cl, thereby blocking nerve signal transmission, nerve palsy, eventually lose muscle contraction ability, This causes the body to die.

Ivermectin is widely used in gastrointestinal nematodes, lungworms and parasitic arthropods of cattle, sheep, horses and pigs, intestinal nematodes of dogs, ear mites, scabies, heartworms and microfilariae, as well as gastrointestinal nematodes and ectoparasites of poultry.
