LINDANE vs OVIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lindane is an organochlorine insecticide that acts by binding to the GABA-A receptor, inhibiting chloride ion influx, leading to hyperexcitation and death of arthropods. It also blocks voltage-gated sodium channels in neurons.
OVIDE (malathion) is an organophosphate insecticide that irreversibly inhibits acetylcholinesterase, leading to accumulation of acetylcholine at synapses, resulting in paralysis and death of lice. It also has pediculicidal and ovicidal activity.
Scabies: Apply 1% lotion or cream thinly to entire body from neck to toes; leave on for 8-12 hours, then wash off. Lice: Apply 1% shampoo to dry hair, lather with water, leave for 4 minutes, then rinse; repeat in 7 days if needed.
Apply OVIDE (malathion 0.5% lotion) topically to dry hair and scalp, leave for 8-12 hours, then rinse thoroughly. Repeat in 7-9 days if live lice persist.

Terminal half-life: 18-21 hours in adults; prolonged in obesity (up to 30-40 hours) due to adipose storage. Accumulation occurs with repeated dermal applications.
Terminal elimination half-life is approximately 8–10 hours in adults; prolonged in hepatic impairment.
Primarily renal; ~50% as metabolites (conjugated and oxidized), <20% unchanged. Fecal excretion accounts for ~10-15% via biliary elimination. Small amounts excreted in sweat.
Primarily renal elimination of metabolites; <1% excreted unchanged in urine. Biliary/fecal excretion accounts for <5%.
