FLEQSUVY vs OVIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FLEQSUVY (fosfomycin tromethamine) is a bactericidal antibiotic that inhibits bacterial cell wall synthesis by inactivating the enzyme UDP-N-acetylglucosamine-3-enolpyruvyltransferase (MurA), which catalyzes the first step of peptidoglycan biosynthesis.
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.
500 mg orally twice daily, preferably with food.
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 elimination half-life is approximately 12 hours (range 10–14 hours) in healthy adults. This supports once-daily dosing in most patients.
Terminal elimination half-life is approximately 8–10 hours in adults; prolonged in hepatic impairment.
Primarily renal excretion as unchanged drug (approximately 70%). Fecal elimination accounts for roughly 20%, with less than 5% as metabolites.
Primarily renal elimination of metabolites; <1% excreted unchanged in urine. Biliary/fecal excretion accounts for <5%.
