CROTAN vs MOXIDECTIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Crotan (crotamiton) is a scabicide and antipruritic agent with unknown exact mechanism. It is thought to act against Sarcoptes scabiei by disrupting nervous system function, possibly via sodium channel modulation, and provides symptomatic relief of pruritus through local anesthetic-like effects.
Moxidectin is a macrocyclic lactone that binds to glutamate-gated chloride ion channels in invertebrate nerve and muscle cells, leading to increased chloride ion influx, hyperpolarization, and paralysis/death of susceptible parasites. It also potentiates gamma-aminobutyric acid (GABA)-gated chloride channels.
Croton oil is not used therapeutically; crotamiton is used as a scabicide. Typical adult dose: Apply 10% cream or lotion topically to entire body from neck to toes, leave on for 24 hours, then wash off; repeat once after 7 days.
Oral: 8 mg once daily for 1-2 days for onchocerciasis; 8 mg once for strongyloidiasis.

Terminal elimination half-life is 4-6 hours in patients with normal renal function; prolonged to 12-24 hours in severe renal impairment, necessitating dose adjustment.
Terminal elimination half-life is approximately 11–12 days in healthy adults; prolonged to 20–30 days in patients with hepatic impairment due to reduced clearance.
Primarily renal excretion of unchanged drug (approx. 60-70%) with biliary/fecal elimination accounting for 20-30%; less than 10% excreted as metabolites.
Primarily fecal (≈75% of total clearance) via biliary excretion of unchanged drug and metabolites; renal excretion accounts for <1% of the dose.
