Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Praziquantel increases the permeability of cell membranes to calcium ions in susceptible schistosomes and other trematodes, causing sustained contraction and paralysis of the worm musculature, leading to detachment from blood vessel walls and eventual death.
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.
60 mg/kg/day orally in 3 divided doses (20 mg/kg/dose) for 1 day.
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.

Terminal elimination half-life is approximately 0.8-1.5 hours for praziquantel; clinical significance: short half-life necessitates multiple dosing for sustained antiparasitic effect.
Terminal elimination half-life is approximately 16 hours; clinically, this supports single-dose administration with slow elimination
Renal excretion accounts for approximately 80-90% of elimination, primarily as metabolites; biliary/fecal excretion is minor (<10%).
Primarily fecal (90%) as unchanged drug via bile; renal excretion is minimal (<1%)
