PIPERAZINE CITRATE vs VERMOX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Piperazine citrate acts as a gamma-aminobutyric acid (GABA) receptor agonist in nematodes, causing hyperpolarization of nerve membranes and flaccid paralysis of the worm, which is then expelled by normal peristalsis. It does not affect mammalian neuromuscular junctions due to differences in GABA receptor sensitivity.
Binds to β-tubulin in parasitic cells, inhibiting microtubule polymerization, thereby impairing glucose uptake and causing energy depletion and parasite death.
Adults: 3.5 g orally once daily for 2 days; may repeat after 1 week if needed.
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: 2-4 hours in patients with normal renal function; may be prolonged in renal impairment.
2-8 hours (terminal half-life, may be prolonged in hepatic impairment or obstruction)
Primarily renal (60-70% unchanged); biliary/fecal elimination accounts for 10-20% of the dose.
Fecal (90%) as unchanged drug and metabolites; renal (<10%)
