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.
Inhibits oxidative phosphorylation in cestodes, leading to paralysis and death of the parasite.
60 mg/kg/day orally in 3 divided doses (20 mg/kg/dose) for 1 day.
2 g orally as a single dose, chewed thoroughly, for taeniasis; may repeat in 1 week for hymenolepiasis.

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.
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.
Renal excretion accounts for approximately 80-90% of elimination, primarily as metabolites; biliary/fecal excretion is minor (<10%).
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.
