Psoriasis is a chronic skin disease, and it is especially characterized by the occurrence of red, itchy, and scaly eruptions on the skin. The quality of life of patients with psoriasis is decreased because this disease remains incurable, despite the rapid progress of therapeutic methods and the introduction of many innovative antipsoriatic drugs. Moreover, many patients with psoriasis are dissatisfied with their current treatment methods and the form with which the drug is applied. The patients complain about skin irritation, clothing stains, unpleasant smell, or excessive viscosity of the preparation. The causes of these issues should be linked with little effectiveness of the therapy caused by low permeation of the drug into the skin, as well as patients' disobeying doctors' recommendations, e.g., concerning regular application of the preparation. Both of these factors are closely related to the physicochemical form of the preparation and its rheological and mechanical properties. To improve the quality of patients' lives, it is important to gain knowledge about the specific form of the drug and its effect on the safety and efficacy of a therapy as well as the patients' comfort during application. Therefore, we present a literature review and a detailed analysis of the composition, rheological properties, and mechanical properties of polymeric gels as an alternative to viscous and greasy ointments. We discuss the following polymeric gels: hydrogels, oleogels, emulgels, and bigels. In our opinion, they have many characteristics (i.e., safety, effectiveness, desired durability, acceptance by patients), which can contribute to the development of an effective and, at the same time comfortable, method of local treatment of psoriasis for patients.
银屑病是一种慢性皮肤病,其特征尤其在于皮肤上出现红色、瘙痒和鳞屑状的皮疹。尽管治疗方法迅速发展,并且引入了许多创新的抗银屑病药物,但由于这种疾病无法治愈,银屑病患者的生活质量下降。此外,许多银屑病患者对他们目前的治疗方法和应用药物的形式不满意。患者抱怨皮肤刺激、衣物染色、异味或制剂的过度粘性。这些问题的原因应该与药物向皮肤渗透不足导致的治疗效果不佳以及患者不遵守医生的建议(例如,定期应用制剂)有关。这两个因素都与制剂的物理化学形式及其流变学和机械性能密切相关。为了提高患者的生活质量,了解药物的具体形式及其对治疗的安全性和疗效以及患者在应用过程中的舒适度的影响非常重要。因此,我们对聚合物凝胶作为粘性和油腻软膏的替代品的组成、流变性能和机械性能进行了文献综述和详细分析。我们讨论了以下聚合物凝胶:水凝胶、油凝胶、乳凝胶和双凝胶。在我们看来,它们具有许多特性(即安全性、有效性、所需的耐久性、患者的接受程度),这有助于为患者开发一种有效且同时舒适的局部治疗银屑病的方法。
