The action is through inhibiting the cholinesterase, causes the worm body muscle to contract strongly, and causes the spastic paralysis; But it doesn't cause ascarid agitation. This product is a depolarizing neuromuscular blocker, which has obvious nicotinoid activity, can also inhibit cholinesterase, make acetylcholine accumulation, lead to spastic paralysis of the worm body and discharge the body; In addition, it can depolarize single cells of the worm body, increase the frequency of peak potential release, increase the muscle tension, and make the worm body lose the independent activity. Different from piperazine, piperazine ACTS quickly, first significantly contracts, and then paralyzes. Roundworm, hookworm, pinworm and their mixed infection were the most effective.
