Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Scabene (Lindane) is an organochlorine insecticide that acts on the gamma-aminobutyric acid (GABA) receptor-chloride channel complex, causing neuronal hyperexcitation and death in arthropods. In scabies mites, it disrupts nervous system function leading to paralysis and death.
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.
Permethrin 5% cream: Apply topically from head to soles of feet, leave on for 8-14 hours, then wash off. Single application for most patients; repeat in 7-14 days if live mites persist.

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).
Terminal elimination half-life is approximately 14-18 hours. In patients with severe renal impairment (CrCl <30 mL/min), half-life may be prolonged to over 30 hours, requiring dose adjustment.
Renal: ~80% (50% as unchanged drug, 30% as inactive metabolites). Biliary/fecal: ~20% (primarily as metabolites).
Primarily renal excretion of unchanged drug and metabolites. Approximately 70-80% of a dose is excreted in urine, with about 10-15% in feces via biliary elimination.
