Metabolite Identification
Common NameCrotamiton
DescriptionCrotamiton is only found in individuals that have used or taken this drug. It is a scabicidal and antipruritic agent available as a cream or lotion for topical use only. It is a colorless to slightly yellowish oil, having a faint amine-like odor. It is miscible with alcohol and with methanol.Crotamiton is an antiparasitic that is toxic to the scabies mite. Crotamiton also relieves itching by producing what is called a counter-irritation. As crotamiton evaporates from the skin, it produces a cooling effect. This cooling effect helps to divert your body's attention away from the itching.
