Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Pyrvinium pamoate inhibits oxidative metabolism and glucose uptake in susceptible helminths, leading to energy depletion and paralysis of the worm. It also binds to DNA and inhibits RNA synthesis in the parasite.
Binds to β-tubulin in parasitic cells, inhibiting microtubule polymerization, thereby impairing glucose uptake and causing energy depletion and parasite death.
Pyrantel pamoate: 11 mg/kg (maximum 1 g) orally once; repeat in 2 weeks for pinworm. For ascariasis, hookworm, trichostrongyliasis: 11 mg/kg (max 1 g) once daily for 3 days.
Mebendazole 100 mg orally twice daily for 3 days for pinworm, whipworm, hookworm, and roundworm infections. For pinworm, may repeat after 2 weeks. For hookworm and whipworm, may require longer courses.

Terminal elimination half-life is approximately 16 hours; clinically, this supports single-dose administration with slow elimination
2-8 hours (terminal half-life, may be prolonged in hepatic impairment or obstruction)
Primarily fecal (90%) as unchanged drug via bile; renal excretion is minimal (<1%)
