The main ingredient of PTA is piperazine phosphate, which is effective in removing roundworms from the body, paralyzing the roundworm body, causing a continuous spasm of the roundworm’s muscles and detaching it from the intestinal wall, and expelling it with the stool. However, it does not have a direct killing effect on roundworms, but only increases the activity and peristalsis of roundworms, so the roundworms expelled from the body are mostly live worms. However, it has a disadvantage that it can make roundworms burrow everywhere, even into the gallbladder, with drill-top-like pain, and require surgery if necessary. At present, Baota sugar has basically been eliminated, and other deworming drugs can be chosen, such as Intestinal Wormer and Enzyme, all of which can directly kill roundworms and have good deworming effect.
