POVAN vs PRAZIQUANTEL
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.
Praziquantel increases the permeability of schistosome cell membranes to calcium ions, causing severe contraction and paralysis of the worm musculature, leading to dislodgment and 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.
20 mg/kg orally three times daily for 1 day for schistosomiasis; 25 mg/kg orally three times daily for 1 day for clonorchiasis and opisthorchiasis; 5-10 mg/kg orally single dose for taeniasis; 15-25 mg/kg orally single dose for hymenolepiasis; 25 mg/kg orally three times daily for 1 day for paragonimiasis, fasciolopsiasis, and heterophyiasis.

Clinical Note
moderatePraziquantel + Tenofovir disoproxil
"The metabolism of Tenofovir disoproxil can be decreased when combined with Praziquantel."
Clinical Note
moderatePraziquantel + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Praziquantel."
Clinical Note
moderatePraziquantel + Erythromycin
"The metabolism of Erythromycin can be decreased when combined with Praziquantel."
Clinical Note
moderatePraziquantel + Cyclosporine
Terminal elimination half-life is approximately 16 hours; clinically, this supports single-dose administration with slow elimination
Terminal elimination half-life is 1-1.5 hours for praziquantel; 4-6 hours for its main metabolite (4-hydroxypraziquantel). Half-life prolonged in patients with severe hepatic impairment.
Primarily fecal (90%) as unchanged drug via bile; renal excretion is minimal (<1%)
Primarily renal: approximately 80% of metabolites excreted in urine (unchanged drug <0.1%); fecal excretion accounts for about 15%.
