Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits oxidative phosphorylation in cestodes, leading to paralysis and death of the parasite.
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.
2 g orally as a single dose, chewed thoroughly, for taeniasis; may repeat in 1 week for hymenolepiasis.
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.

The terminal elimination half-life of niclosamide is approximately 2-6 hours in patients with normal renal function; however, clinical efficacy against cestodes is prolonged due to its local action in the gastrointestinal tract.
Terminal elimination half-life is approximately 16 hours; clinically, this supports single-dose administration with slow elimination
Niclosamide is predominantly excreted in feces as unchanged drug and metabolites after oral administration. Renal excretion of metabolites accounts for less than 2% of an administered dose. Approximately 70% of the dose is recovered in feces within 2-3 days.
Primarily fecal (90%) as unchanged drug via bile; renal excretion is minimal (<1%)
