🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionPermethrin is minimally absorbed through intact human skin. Systemic absorption is less than 2% of the applied dose.
DistributionDue to minimal absorption, systemic distribution is negligible. Any absorbed permethrin is widely distributed but rapidly metabolized.
Protein BindingPermethrin and its metabolites are highly protein-bound in plasma, but specific data are not established from the available information.
MetabolismPermethrin is rapidly metabolized in the liver by esterases to inactive metabolites.
Half-LifeThe elimination half-life of permethrin is not established from the available information.
ExcretionMetabolites are excreted primarily in the urine.
BioavailabilityBioavailability after topical application is very low, typically less than 2%.
Onset of ActionThe onset of action against mites is not immediate; it may take several hours to days for the mites to die after application.
Peak Plasma TimeNot established from the available information.
Duration of ActionThe acaricidal effect persists on the skin for several days after application.

How It Works

Permethrin acts on the nerve cell membranes of parasites by interfering with sodium channels. It delays the closure of sodium channels, leading to prolonged depolarization and blockage of nerve impulse transmission. This results in paralysis and death of the mites. Permethrin has low toxicity to humans because it is poorly absorbed through intact skin and is rapidly metabolized.

Mechanism Steps

1
Penetration into mite nervous system: Permethrin penetrates the exoskeleton of the mite and reaches the nerve cells.
2
Binding to sodium channels: It binds to voltage-gated sodium channels in the nerve cell membrane.
3
Prolonged depolarization: This binding delays the closure of sodium channels, causing prolonged depolarization.
4
Blockage of nerve impulses: The prolonged depolarization blocks the transmission of nerve impulses.
5
Paralysis and death of mites: The mites become paralyzed and eventually die, resolving the infestation.
