Permin

Uses

Permin is used for the treatment of scabies.

Permin is also used to associated treatment for these conditions: Head Lice Infestation, Norwegian scabies, Scabies, Lice of the pubic area

How Permin works

Permin acts on the nerve cell membrane to disrupt the sodium channel current by which the polarization of the membrane is regulated. Delayed repolarization and paralysis of the pests are the consequences of this disturbance.

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 Permin 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.

Precaution

Permin is not an eye-irritant, but the cream itself may cause marked irritation. Nursing staff who routinely apply Permin, may wear gloves to avoid any possible irritation to the hands.

Interaction

The treatment of eczematous-like reactions with corticosteroids should be withheld prior to treatment with Permin, as there is a risk of exacerbating the scabies infestation by reducing the immune response to the mite.

Food Interaction

Elimination Route

Poorly absorbed through the skin.

Elimination Route

Permin is rapidly metabolized by ester hydrolysis to inactive metabolites which are excreted primarily in the urine.

Pregnancy & Breastfeeding use

There are limited data on the use of Permin in pregnancy which provide no indication of any risk to the foetus. Furthermore, the amount of Permin absorbed systemically following a whole body application is extremely low. The negative mutagenicity tests and the very low mammalian toxicity would suggest that any risk to the foetus following treatment with Permin is minimal. Inspite of these, Permin is suggested not to useduring pregnancy.

It is not known whether Permin is excreted in human breast milk. So, it should not be used in nursing mothers.

Contraindication

Permin is contraindicated in subjects with known hypersensitivity to the product, its components, other pyrethroids or pyrethrins.

Acute Overdose

There are no reports of overdosage with Permin. It is possible that excessive application of Permin might result in localized adverse reactions or more severe skin reactions.

Storage Condition

Store at a cool and dry place. Protect from light. Do not freeze.
