POVAN vs VERMIDOL
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.
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.
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.
200 mg orally twice daily for 3 days; maximum 400 mg per day.

Terminal elimination half-life is approximately 16 hours; clinically, this supports single-dose administration with slow elimination
Terminal elimination half-life: 8-12 hours (mean 10 h); prolonged in renal impairment (up to 24 h) and elderly.
Primarily fecal (90%) as unchanged drug via bile; renal excretion is minimal (<1%)
Renal: ~60-70% as unchanged drug; biliary/fecal: ~20-30%; minor metabolism via hepatic CYP3A4.
