There is limited information available regarding patient preferences and attributes of topical product formulations for specific dermatologic conditions. This study focused on product attributes that were most desirable for 3 dermatologic conditions: acne, atopic dermatitis (AD), and plaque psoriasis (PP). Six focus groups were conducted with participants self-reporting 1 of these conditions and use of 2 or more topical treatments. Discussion focused on symptoms, treatments tried, and vehicle attributes. Fifty-four subjects participated: acne, n=19; AD, n=18; and PP, n=17. The most commonly reported prescription medication vehicles were creams and ointments, followed by lotions, gels, and foams. Itching and redness were the only symptoms spontaneously reported across all 6 focus groups. The attributes considered most important across all conditions included: moisturizing, absorbs/disappears/dries quickly, available in various formulations, does not bleach or stain skin/hair/clothing, is not greasy or oily, is not sticky or tacky, is long lasting/long acting, is fragrance or odor free, is easy to apply/simple to use, and can use all the time. Preferences attributable to acne included: easy to dispense/dispenses right amount, nondrying, product goes on/spreads smoothly, container is not easily broken/does not leak, and creamy. Preferences attributable to AD included: not noticeable to others/conceals area, good consistency, and cooling. Patient preference for product vehicle is relevant to adherence as compliance is a major factor for high rates of failure for dermatologic treatments.
关于特定皮肤病患者对局部用产品配方的偏好和属性的信息有限。本研究聚焦于三种皮肤病最理想的产品属性:痤疮、特应性皮炎(AD)和斑块状银屑病(PP)。对六个焦点小组进行了研究,参与者自述患有这三种疾病中的一种且使用过两种或更多局部治疗方法。讨论集中在症状、尝试过的治疗方法和载体属性上。共有54名受试者参与:痤疮组,n = 19;特应性皮炎组,n = 18;斑块状银屑病组,n = 17。最常报告的处方药载体是乳膏和软膏,其次是洗剂、凝胶和泡沫剂。瘙痒和发红是所有六个焦点小组中唯一自发报告的症状。在所有疾病中被认为最重要的属性包括:保湿、吸收/消失/干燥快、有多种配方、不漂白或染色皮肤/头发/衣物、不油腻、不粘腻、持久/长效、无香料或气味、易于涂抹/使用简单、可随时使用。痤疮患者的偏好包括:易于挤出/挤出量合适、不干燥、产品涂抹/铺开顺滑、容器不易破裂/不漏液、呈乳状。特应性皮炎患者的偏好包括:他人不易察觉/能遮盖患病部位、质地均匀、有清凉感。患者对产品载体的偏好与依从性相关,因为依从性是皮肤病治疗失败率高的一个主要因素。
