説明
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.
化学的特性

使用
N-Ethyl-o-crotonotoluidide (Crotamiton) was used to treat scabies and various pruritic dermatoses.
適応症
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.

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.
