ALBENZA vs PRAZIQUANTEL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Albendazole is a benzimidazole carbamate that inhibits tubulin polymerization by binding to the colchicine site of β-tubulin, disrupting microtubule formation. This leads to impaired uptake of glucose and depletion of glycogen stores, resulting in immobilization and death of susceptible helminths.
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.
400 mg orally twice daily for 60 days for neurocysticercosis; 400 mg orally once daily for 3 days for pinworm; 400 mg orally once daily for 3 days for hookworm, roundworm, whipworm; 400 mg orally twice daily for 3 days for tapeworms; 400 mg orally twice daily for 7 days for giardiasis.
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.

Terminal elimination half-life of albendazole sulfoxide (active metabolite) is 8-12 hours; albendazole itself has a very short half-life (<1 hour) due to extensive first-pass metabolism.
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 biliary/fecal (less than 2% renal as unchanged drug and metabolites; most eliminated via bile into feces as metabolites).
Primarily renal: approximately 80% of metabolites excreted in urine (unchanged drug <0.1%); fecal excretion accounts for about 15%.
