VANSIL vs VERMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Vansil (oxamniquine) is an antischistosomal agent that increases calcium permeability in susceptible schistosomes, leading to muscle contraction, paralysis, and eventual death of the parasite. It is specifically active against Schistosoma mansoni.
Binds to β-tubulin in parasitic cells, inhibiting microtubule polymerization, thereby impairing glucose uptake and causing energy depletion and parasite death.
20 mg/kg orally twice daily for 1 day (maximum single dose: 1 g).
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 85-105 hours in patients with normal renal function, allowing once-daily dosing; prolonged in renal impairment
2-8 hours (terminal half-life, may be prolonged in hepatic impairment or obstruction)
Primarily renal (70-80% as unchanged drug) with minor biliary/fecal elimination (15-20%) and hepatic metabolism (10-15%)
Fecal (90%) as unchanged drug and metabolites; renal (<10%)
