MALATHION vs RID MOUSSE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Malathion is an organophosphate that irreversibly inhibits acetylcholinesterase, leading to accumulation of acetylcholine at cholinergic synapses, causing overstimulation of muscarinic and nicotinic receptors.
RID Mousse contains pyrethrins and piperonyl butoxide. Pyrethrins act on the nervous system of lice by disrupting sodium channels, causing paralysis and death. Piperonyl butoxide inhibits insect cytochrome P450 microsomal enzymes, enhancing the activity of pyrethrins.
0.5% lotion applied topically to entire body and left for 8-12 hours; repeat in 7-9 days if necessary.
Topical: Apply twice daily (morning and evening) to affected areas of the scalp and/or skin. Use enough to cover the area, typically 1–2 mL per application. Rinse after 1–3 minutes.

Clinical Note
moderateMalathion + Deferasirox
"The serum concentration of Deferasirox can be increased when it is combined with Malathion."
Clinical Note
moderateMalathion + Tenofovir disoproxil
"The metabolism of Tenofovir disoproxil can be decreased when combined with Malathion."
Clinical Note
moderateMalathion + Clotrimazole
"The metabolism of Clotrimazole can be decreased when combined with Malathion."
Clinical Note
moderateMalathion + Venlafaxine
Approximately 2-3 hours for malathion (parent compound). Metabolites (e.g., malaoxon) may persist longer. Clinically, elimination is rapid, limiting systemic toxicity with acute dermal exposure.
Terminal elimination half-life is 24 hours (range 20-30 hours); clinically, steady-state is reached after 5-7 days.
Primarily renal excretion of water-soluble metabolites (e.g., malathion monocarboxylic acid, dicarboxylic acid). Less than 1% excreted unchanged in urine. Biliary/fecal excretion accounts for minor elimination of metabolites.
Renal excretion of unchanged drug accounts for approximately 60% of elimination; fecal/biliary elimination accounts for 25%; 15% metabolized with metabolites excreted renally.
