DESCRIPTION
Permethrin Cream, 5% is a topical scabicidal agent for the treatment
of infestation with _Sarcoptes scabiei_
(scabies). It is available in an off-white, vanishing cream base.
Permethrin Cream, 5% is for topical use
only.
CHEMICAL NAME – The permethrin used is an approximate 1:3 mixture of
the cis and trans isomers of the
pyrethroid 3-(2,2-dichloroethenyl)-2,2-dimethylcyclopropanecarboxylic
acid, (3-phenoxyphenyl)
methyl ester. Permethrin has a molecular formula of C
H Cl
O and a molecular weight of 391.29. It
is a yellow to light orange-brown, low melting solid or viscous
liquid.
ACTIVE INGREDIENT – Each gram contains permethrin 50 mg (5%).
INACTIVE INGREDIENTS – Butylated hydroxytoluene, carbomer
homopolymer type B, fractionated coconut
oil, glycerin, glyceryl monostearate, isopropyl myristate, lanolin
alcohols, mineral oil, polyoxyethylene
cetyl ethers, purified water, and sodium hydroxide. Formaldehyde 1 mg
(0.1%) is added as a
preservative.
CLINICAL PHARMACOLOGY
Permethrin, a pyrethroid, is active against a broad range of pests
including lice, ticks, fleas, mites, and
other arthropods. It 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.
Permethrin is rapidly metabolized by ester hydrolysis to inactive
metabolites which are excreted
primarily in the urine. Although the amount of permethrin absorbed
after a single application of the 5%
cream has not been determined precisely, data from studies with
C-labeled permethrin and absorption
studies of the cream applied to patients with moderate to severe
scabies indicate it is 2% or less of the
amount applied.
