Levamisole Injection is a broad-spectrum anti-nematode drug, with levamisole as the main component. It exerts deworming effect by inhibiting the succinate dehydrogenase activity in nematodes, blocking the energy metabolism of the worms, causing muscle paralysis and expulsion from the body. It is suitable for infections caused by various nematodes in livestock and poultry (such as pigs, cattle, sheep, chickens, etc.), such as roundworms, hookworms, pinworms, whipworms, etc. Administered by intramuscular injection, the drug can be quickly absorbed and distributed to the whole body tissues, especially with high concentration in the intestines, which can rapidly act on parasitic nematodes and effectively expel adults and larvae. It is a commonly used drug in farms for preventing and treating nematodiasis in livestock and poultry, which can reduce the damage and nutrient plunder of nematodes to the intestines of livestock and poultry.
