Beschreibung
Crotamiton is available as a 10% cream for the treatment of scabies, although it is less effective
than pyrethrins or permethrin. Because crotamiton may need to be applied a second time
for successful treatment of scabies but the pyrethrins or permethrin require a single application,
poor patient compliance with crotamiton may reduce its effectiveness. The advantage of crotamiton
over lindane comes from the fact that lindane has potential neurotoxicity if absorbed especially in
infants and children, whereas crotamiton has less systemic neurotoxicity.
Chemische Eigenschaften
N-Ethyl-o-crotonotoluidide is colourless or pale yellow, oily liquid
Verwenden
N-Ethyl-o-crotonotoluidide (Crotamiton) was used to treat scabies and various pruritic dermatoses.
Indications
Crotamiton (N-ethyl-o-crotonotoluide, Eurax) is a synthetic chloroformate salt used
for the prevention and treatment of scabies, although cure rates tend to be lower
for the same number of applications compared with lindane and permethrin. It may
have an antipruritic effect independent of its scabetic effect. Its mechanism of action
is unknown. It is not effective as a pediculicide.
Crotamiton (10% N-ethyl-o-crotonotoluide, Eurax) cream applied twice and
left on during a 48-hour period is usually effective against scabies and has been
reported to act as an antipruritic agent.
Definition
ChEBI: The amide resulting from the formal condensation of crotonic acid with N-ethyl-2-methylaniline. A colourless or pale yellow oily liquid, it is used in the treatment of pruritus (itching) by producing a counter-irritation: as it evaporate
from the skin, it produces a cooling effect that diverts attention away from the itching. It has also been used as an acaricide in the treatment of scabies, though more effective drugs are usually preferred.
Clinical Use
N-Ethyl-N-(2-methylphenyl)-2-butenamide, or N-ethyl-ocrotonotoluidide(Eurax), is a colorless, odorless oily liquid.It is virtually insoluble in water but soluble in most organicsolvents.
Crotamiton is available in 10% concentration in a lotionand a cream intended for the topical treatment of scabies. Its antipruritic effect is probably because of a local anestheticaction.
Nebenwirkungen
The most common side
effect reported for crotamiton is skin irritation.
