Pertrin (Permethrin)
Pertrin (Permethrin) Uses, Dosage, Side Effects, Food Interaction and all others data.
Pertrin (Permethrin) induces electrochemical abnormalities across the membranes of excitable cells, leading to sensory hyperexcitability, in coordination and prostration. Pertrin (Permethrin) is rapidly metabolized in mammals by ester hydrolysis to inactive metabolites which are excreted primarily in the urine. The principal metabolites of Pertrin (Permethrin) are detectable in the urine within hours of a whole body application of the cream to healthy volunteers or scabies patients. The highest levels of excretion are detectable within the first 48 hours, but very low levels of metabolites are still detectable in the urine of some individuals 28 days after treatment.
Pertrin (Permethrin), a pyrethroid, is active against a broad range of pests including lice, ticks, fleas, mites, and other arthropods.

Side Effects
In scabies patients, skin discomfort, usually described as burning, stinging or tingling occurs in a few individuals soon after the cream is applied. Other transient signs and symptoms of irritation including erythema, edema, eczema, rash and pruritus which may follow the treatment of scabies with Pertrin (Permethrin) are generally considered to be the part of the natural history of scabies. In patients treated for scabies, itching may persist for up to 4 weeks post-treatment. This is generally regarded as due to an allergic reaction to the dead mites under the skin and is not necessarily indicative of a treatment failure.
Toxicity
Oral, rat LD50: 430 - 4000 mg/kg; skin, rabbit LD50: 2000 mg/kg.
