PRAZIQUANTEL vs STROMECTOL
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.
Ivermectin acts by binding selectively and with high affinity to glutamate-gated chloride ion channels in invertebrate nerve and muscle cells, leading to increased permeability to chloride ions, hyperpolarization of nerve or muscle cells, and death of the parasite. It also interacts with other ligand-gated chloride channels, such as those gated by gamma-aminobutyric acid (GABA).
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.
Oral: 200 mcg/kg once daily for 1-2 days. For strongyloidiasis, 200 mcg/kg/day for 2 days. For onchocerciasis, single dose of 150 mcg/kg.

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 is approximately 18 hours (range 10–30 hours) in healthy subjects; prolonged in hepatic impairment.
Primarily renal: approximately 80% of metabolites excreted in urine (unchanged drug <0.1%); fecal excretion accounts for about 15%.
Primarily fecal (90%) as unchanged drug and metabolites; renal excretion accounts for <1% of the dose.
