PRAZIQUANTEL vs VERMIDOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
VERMIDOL is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis and attenuating pain, inflammation, and fever.
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.
200 mg orally twice daily for 3 days; maximum 400 mg per day.

Clinical Note
moderatePraziquantel + Tenofovir disoproxil
"The metabolism of Tenofovir disoproxil can be decreased when combined with Praziquantel."

"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 1-1.5 hours for praziquantel; 4-6 hours for its main metabolite (4-hydroxypraziquantel). Half-life prolonged in patients with severe hepatic impairment.
Terminal elimination half-life: 8-12 hours (mean 10 h); prolonged in renal impairment (up to 24 h) and elderly.
Primarily renal: approximately 80% of metabolites excreted in urine (unchanged drug <0.1%); fecal excretion accounts for about 15%.
Renal: ~60-70% as unchanged drug; biliary/fecal: ~20-30%; minor metabolism via hepatic CYP3A4.
