The role is to inhibit cholinesterase, so that the body muscles contract strongly, and cause spastic paralysis; but does not cause roundworm disturbance. This product is a depolarizing neuromuscular blocker with obvious nicotinic activity. It can also inhibit cholinesterase, accumulate acetylcholine, and cause spastic paralysis and excretion of the insect body; in addition, it can make the insect body single The cell depolarizes, the frequency of spike firing increases, and muscle tension also increases, causing the worm to lose its autonomous activity.

Roundworms, hookworms, pinworms and their mixed infections have the best effect on repelling hookworms.
