![]() ![]() Although the amount of Permethrin absorbed after a single application of the 5% cream has not been determined precisely, data from studies with 14C-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. Permethrin is rapidly metabolized by ester hydrolysis to inactive metabolites which are excreted primarily in the urine. Delayed repolarization and paralysis of the pests are the consequences of this disturbance. It acts on the nerve cell membrane to disrupt the sodium channel current by which the polarization of the membrane is regulated. Permethrin, a pyrethroid, is active against a broad range of pests including lice, ticks, fleas, mites, and other arthropods. Formaldehyde 1 mg (0.1%) is added as a preservative. 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. It is a yellow to light orange-brown, low melting solid or viscous liquid.Īctive Ingredient – Each gram contains Permethrin 50 mg (5%). Permethrin has a molecular formula of C 21H 20Cl 2O 3 and a molecular weight of 391.29. It can be concluded that the application of permethrin 5% cream twice daily for 2 months can be as effective and reliable as metronidazole in the treatment of rosacea and a greater benefit can be gained when it is combined with other systemic and/or topical treatments.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. ![]() However, it had no effect on telangiectasia, rhinophyma and pustules. The effect of permethrin 5% cream on erythema and papules was found to be more effective than placebo and as effective as metronidazole 0.75% gel. folliculorum was superior to that of metronidazole 0.75% gel. folliculorum were determined at baseline and on days 15, 30, 45 and 60. The mean scores of erythema and the mean numbers of papules, pustules and D. folliculorum were recorded at each visit. Scores of erythema, telangiectasia, edema and rhinophyma and the numbers of papules, pustules, inflammatory nodules and D. Two months of treatment were planned, and the patients were invited to the clinic for fortnightly controls. ![]() All patients were also given SPF 20 cream for protection against sunlight. Twenty-three patients were given permethrin 5% cream (Zalvor 5% skin cream, 20 patients metronidazole 0.75% gel (Roza gel and 20 patients placebo cream (Basis cream, in packages looking identical to those of metronidazole and permethrin creams, and were recommended to apply them to their faces twice a day. Scores of erythema, telangiectasia, edema and rhinophyma and the numbers of papules, pustules, inflammatory nodules and Demodex folliculorum were determined. Patients were randomly assigned into permethrin (n = 23), metronidazole (n = 20) and placebo (n = 20) groups. This study included 63 patients diagnosed as having papulopustular rosacea based on the clinical and histological findings. Permethrin 5% cream used against human ectoparasites suggests that it may be effective in papulopustular rosacea. ![]()
