Stibophen is an anthelmintic classified as antimony compound and used as treatment of schistosomiasis[1] by intramuscular injection.

Mechanism of action[edit]

Stibophen inhibits the enzyme phosphofructokinase, which the worms need for glycolysis,[2] at least partly by binding to the sulfhydryl (–SH) group of the enzyme.[3] Inhibiting glycolysis paralyzes the worms, which lose their hold on the wall of mesenteric veins and undergo hepatic shift, die, and are phagocytosed by liver cells.[citation needed]
