Itch is frequently associated with dermatoses characterized by a defective skin barrier. We formulated an itch-relieving moisturizing cream containing 3% menthol and ceramides. Our aim was to evaluate the safety and antipruritic efficacy of application of this cream in volunteers with and without skin diseases. Volunteers were asked to apply the cream for 1 month on a minimum body surface area of 6%. Safety was assessed by the absence of contact dermatitis or other side effects, using a self-administered questionnaire completed at 5 minutes, 1 week, and 1 month after application. To determine efficacy, volunteers with pruritic dermatoses were asked to grade their average itch intensity at baseline, 1 week, and 1 month after application. Sixty volunteers were recruited, of whom 41 had no skin disease; no adverse events were reported in the latter. Of the 19 volunteers with dermatoses, 18 reportedly had atopic dermatitis. One of the 60 volunteers stopped application due to stinging sensations induced by menthol. Itch scores of volunteers with dermatitis improved from baseline at 1 week (=.01) and 1 month (<.01) after application. Application of a 3% menthol-containing moisturizing cream was safe in healthy individuals and participants with dermatitis. In the latter, itch scores were significantly reduced during follow-up.
瘙痒常与以皮肤屏障功能缺陷为特征的皮肤病相关。我们配制了一种含有3%薄荷醇和神经酰胺的止痒保湿霜。我们的目的是评估在有皮肤病和无皮肤病的志愿者中应用这种乳膏的安全性和止痒效果。志愿者被要求在至少6%的身体表面积上涂抹该乳膏1个月。通过在涂抹后5分钟、1周和1个月完成的一份自我管理问卷来评估安全性,看是否存在接触性皮炎或其他副作用。为了确定疗效,要求患有瘙痒性皮肤病的志愿者在涂抹前、涂抹后1周和1个月对他们的平均瘙痒强度进行评分。招募了60名志愿者,其中41人没有皮肤病;后者未报告不良事件。在19名患有皮肤病的志愿者中,据报告18人患有特应性皮炎。60名志愿者中有1人因薄荷醇引起的刺痛感而停止涂抹。患有皮炎的志愿者的瘙痒评分在涂抹后1周(P = 0.01)和1个月(P < 0.01)时较基线有所改善。在健康个体和患有皮炎的参与者中,涂抹含3%薄荷醇的保湿霜是安全的。在后者中,随访期间瘙痒评分显著降低。
