The present invention relates to complex particles using methylene blue for treating a skin disease caused by Propionibacterium acnes or Staphylococcus aureus and a composition for treatment including the complex particles. The complex particles in the present invention can be used as a photosensitizer for a photodynamic therapy and complex particles having a micelle form in which hydrophilic methylene blue and two hydrophobic organic acids are combined, and as a result, pore penetration is easy and an occlusion time can be significantly reduced to 30 minutes as compared with conventional phototherapy requiring an occlusion time of 1 hour to 3 hours. Further, in order to reduce side effects of a residual photosensitizer in phototherapy using an existing photosensitizer due to photoreaction and photobleaching of the methylene blue-organic acid complex, a light protection (light blocking or light shielding) time when contact of light needs to be avoided for 24 hours or more after treatment can be significantly reduced to 3 hours, and target treatment for Propionibacterium acnes, Staphylococcus aureus, or the like which is a cause of acne is possible.
本发明涉及使用
亚甲基蓝治疗由痤疮
丙酸杆菌或
金黄色葡萄球菌引起的皮肤病的复合物颗粒,以及包括该复合物颗粒的治疗组合物。本发明中的复合物微粒可用作光动力疗法的光敏剂,复合物微粒具有胶束形式,其中亲
水性
亚甲基蓝和两种疏
水性有机酸结合在一起,因此,与传统光疗法需要 1 小时至 3 小时的闭塞时间相比,本发明中的复合物微粒易于毛孔渗透,闭塞时间可显著缩短至 30 分钟。此外,为了减少在使用现有光敏剂的光疗中因
亚甲蓝-有机酸复合物的光反应和光漂白而产生的残留光敏剂的副作用,可将治疗后 24 小时或更长时间内需要避免接触光的光保护(光阻挡或光屏蔽)时间大幅缩短至 3 小时,并可对痤疮
丙酸杆菌、
金黄色葡萄球菌等导致痤疮的细菌进行针对性治疗。
