It is a highly effective broad-spectrum anthelmintic drug that affects the metabolic pathways of the worms, thus interfering with their survival and reproduction and leading to their death. In addition to adult worms, this drug can also kill eggs and larvae, and is used clinically to treat nematodes, tapeworm and trematode diseases. It is slowly absorbed orally, metabolized in the liver, and most of it is excreted in the urine. This drug should be contraindicated in patients with severe cardiac, hepatic, or renal insufficiency or active ulcers, as well as in women during the lactation period, and has few adverse effects.
