Especially strong killing effect on schistosomiasis tapeworms, is currently the best a middle fruit.

Use of anti worm medicine, mainly for schistosomiasis, also can be used for the Chinese branch of schistosomiasis, taeniasis and cysticercosis paragonimiasis, etc.

Production method of industrial production and various synthetic routes: isoquinoline route, piperazine route and phenylethylamine route, which better with quinoline route. Catalytic hydrogenation by isoquinoline with benzoyl chloride and potassium cyanide addition, rearrangement of 1- benzoyl amino methyl -1, 2, 3, four 4- hydrogen isoquinoline, then by chloromethylation, cyclization, pressurized hydrolysis, cyclohexyl acylation and.

Production method by using phenylethylamine as raw material, by acylation with chloroacetyl chloride, and then to two benzene carboxamide potassium amination reaction to introduce amino group, in three phosphorus oxychloride role under the condition 3, 4- two hydrogen isoquinoline derivatives, 1- aminomethyl four tetrahydroquinoline obtained by hydrogenation, hydrolysis, successively with cyclohexyl methyl chloride and chloroacetic chloride acylation, finally dehydrochlorination cyclizes to praziquantel.

Can also be isoquinoline as raw materials, through Reissert reaction, at the L position and introduction of cyano nitrogen benzoylation, then hydrogenation, while benzoyl transfer to the side chain amino group, then in the ring on the amino introducing chloro acetyl, then cyclization, hydrolysis, cyclohexyl formylation to praziquantel.
