    • The present invention is drawn to systems, methods, and formulations for treating nail disorders. The system comprises an active agent formulation and a first barrier film. The active agent formulation includes an active agent and an aqueous liquid component. The first barrier film is configured to form a sheath over at least a portion of a finger or toe on which the nail is located. An optional second barrier film, with lower moisture vapor transmission rate than the first barrier film, is placed between the first barrier film and the active agent formulation (or between the active agent formulation and the external environment) to reduce the water evaporation from the active agent formulation. The sheath is configured to be capable of securing and retaining the active agent formulation within the sheath on a finger nail or toe nail while reducing evaporation of the liquid component of the aqueous liquid component of the active agent formulation. The active agent formulation can be a 'slow-molding' hydrogel formulation that can slowly flow into the exact shape of the diseased nail to assure intimate contact and continuous delivery of the drug, while cannot be squeezed out of the position during the application.
    • 本发明涉及治疗指甲疾病的系统,方法和制剂。 该系统包含活性剂制剂和第一阻隔膜。 活性剂制剂包含活性剂和含水液体组分。 第一阻挡膜被构造成在指甲所位于的手指或脚趾的至少一部分上形成护套。 在第一隔离膜和活性剂制剂之间(或在活性剂制剂和外部环境之间)放置具有比第一隔离膜更低的湿气渗透率的可选的第二隔离膜以减少活性剂从活性剂 剂配方。 护套构造成能够将活性剂制剂固定并保持在指甲或脚趾甲上的护套内,同时减少活性剂制剂的水性液体组分的液体组分的蒸发。 活性剂制剂可以是'慢模制'水凝胶制剂,其可以缓慢流入患病指甲的确切形状以确保药物的紧密接触和连续递送,而在施用期间不能挤出位置。 / p>
