Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Ivermectin is a macrocyclic lactone that binds selectively and with high affinity to glutamate-gated chloride ion channels in invertebrate nerve and muscle cells, leading to increased chloride ion influx, hyperpolarization, and paralysis of the parasite. It also interacts with other ligand-gated chloride channels, such as those gated by gamma-aminobutyric acid (GABA). In mammals, these channels are largely confined to the central nervous system, but ivermectin does not readily cross the blood-brain barrier, providing a safety margin.
Binds to β-tubulin in parasitic cells, inhibiting microtubule polymerization, thereby impairing glucose uptake and causing energy depletion and parasite death.
150–200 mcg/kg orally once, with repeat dose in 2 weeks for strongyloidiasis; for scabies, 200 mcg/kg orally once, repeat in 2 weeks 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.

Clinical Note
moderateIvermectin + Teriflunomide
"The serum concentration of Teriflunomide can be increased when it is combined with Ivermectin."
Clinical Note
moderateIvermectin + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Ivermectin."
Clinical Note
moderateIvermectin + Erythromycin
"The metabolism of Erythromycin can be decreased when combined with Ivermectin."
Clinical Note

Terminal elimination half-life is approximately 18 hours (range 12-24 hours) in healthy adults; prolonged in hepatic impairment.
2-8 hours (terminal half-life, may be prolonged in hepatic impairment or obstruction)
Primarily fecal (≥90% as unchanged drug and metabolites); renal excretion is minimal (<1% of dose). Biliary excretion contributes to fecal elimination.
