Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Crotamiton exerts scabicidal and antipruritic effects by an unknown mechanism. It is thought to interfere with the nervous system of Sarcoptes scabiei, leading to mite death, and may also have a direct anti-inflammatory effect on the skin.
Gamma benzene hexachloride (lindane) is an ectoparasiticide and scabicide that acts by penetrating the exoskeleton and disrupting the nervous system of parasites, leading to paralysis and death. It also has toxic effects on the central nervous system of humans.
Apply topically as a 10% cream or lotion; massage thoroughly into skin from chin to toes, especially skin folds; leave on for 8-14 hours then wash off. Repeat in 7 days.
Adults: Apply 1% permethrin cream (Kwell) topically to all skin areas from neck to toes, leave on for 8-14 hours, then wash off. Single application is usually sufficient; repeat in 7 days if live lice persist.

Terminal half-life is approximately 35-45 hours in adults, allowing for once-daily dosing in most indications.
Terminal elimination half-life: 11-17 hours (mean 14 hours) in adults; prolonged in hepatic impairment (up to 30 hours) or severe renal impairment (up to 24 hours).
Primarily renal (approximately 70% as unchanged drug and metabolites); biliary/fecal excretion accounts for about 20-30%.
Renal: ~80% (50% as unchanged drug, 30% as inactive metabolites). Biliary/fecal: ~20% (primarily as metabolites).
