🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionPermethrin is poorly absorbed through intact human skin. Systemic absorption is minimal when applied topically as directed. Any absorbed permethrin is rapidly metabolized by esterases in the skin and liver.
DistributionDue to minimal systemic absorption, permethrin does not distribute significantly into body tissues. It remains primarily at the site of application.
Protein BindingNot established from the available information.
MetabolismPermethrin is metabolized in the skin and liver by esterases to inactive metabolites, which are then excreted.
Half-LifeNot established from the available information.
ExcretionMetabolites of permethrin are excreted primarily in the urine.
BioavailabilityNot established from the available information.
Onset of ActionThe onset of action against parasites is not immediate; it may take several hours to days for the full effect. Symptom relief, such as reduced itching, may begin within a few days after treatment.
Peak Plasma TimeNot established from the available information.
Duration of ActionThe acaricidal and pediculicidal effects persist on the skin for some time after application, but the exact duration is not well established. Typically, a single application is sufficient for scabies treatment.

How It Works

Permethrin, the active ingredient in this medicine, is a synthetic pyrethroid that acts as a neurotoxin against parasites. It binds to voltage-gated sodium channels in the nerve cells of mites and lice, delaying their closure and causing prolonged depolarization. This leads to paralysis and eventual death of the parasite. Permethrin has low toxicity to humans because it is rapidly metabolized by human skin and liver enzymes, and it has poor absorption through intact skin.

Mechanism Steps

1
Penetration into parasite: Permethrin penetrates the exoskeleton of the mite or louse and reaches its nervous system.
2
Binding to sodium channels: Permethrin binds to voltage-gated sodium channels in the nerve cells, preventing them from closing properly.
3
Prolonged depolarization: The persistent sodium influx causes prolonged depolarization of the nerve membrane, leading to repetitive firing and hyperexcitation.
4
Paralysis and death: The hyperexcitation eventually leads to paralysis and death of the parasite.
