Recent Pat Antiinfect Drug Discov. 2018;13(2):127-150. doi: 10.2174/1574891X13666180529103804.
Topical infections, involving a number of diseases such as impetigo, eczema, pustular acne, psoriasis and infected seborrheic dermatitis are one among the many challenges to health which stand out for their profound impact on human species. The treatment of topical infections has always been a difficult proposition because of the lack of efficacy of existing anti-infectives, longer period of treatment and yet incomplete recovery. The increasing emergence of antibiotic resistant bacterial strains like Staphylococcus aureus, Methicillin-Resistant Staphylococcus aureus (MRSA) and Pseudomonas aeruginosa undermines the need for the development of new delivery systems to enhance the therapeutic efficacy of existing topical anti-infectives.
The application of nanotechnology to medicine, or nanomedicine, is rapidly becoming a major driving force behind ongoing changes in the anti-infective field because of its interaction at the sub-atomic level with the skin tissue. The latter, in the current scenario, points towards vesicular carriers like liposomes, lipidic nanoparticles and silver nanoparticles. as the most promising drug delivery solutions for topical infection disorders. These have exhibited immense significance owing to their uniqueness to facilitate the interactions at interfaces with the barrier membranes.
The present review summarizes the emerging efforts in combating topical infections particularly using nanomedicine based delivery systems as new tools to tackle the current challenges in treating infectious diseases. Besides, compiling various research reports, this article also includes formulation considerations, mechanisms of penetration and patents reported.
Despite the new emerging technologies and delivery systems, efforts are still needed in the right direction to combat this global challenge.
局部感染涉及脓疱病、湿疹、脓疱性痤疮、银屑病和感染性脂溢性皮炎等多种疾病,是对健康的众多挑战之一,因其对人类有着深远影响而备受关注。由于现有抗感染药物疗效不佳、治疗周期长且恢复不完全,局部感染的治疗一直是个难题。金黄色葡萄球菌、耐甲氧西林金黄色葡萄球菌(MRSA)和铜绿假单胞菌等抗生素耐药菌株的不断出现,凸显了开发新给药系统以提高现有局部抗感染药物治疗效果的必要性。
纳米技术在医学中的应用,即纳米医学,正迅速成为抗感染领域持续变革的主要驱动力,因为它在亚原子水平与皮肤组织相互作用。在当前情况下,这指向了脂质体、脂质纳米颗粒和银纳米颗粒等囊泡载体,作为局部感染性疾病最有前景的药物递送解决方案。由于它们在促进与屏障膜界面相互作用方面的独特性,这些载体已显示出巨大的意义。
本综述总结了在对抗局部感染方面的新进展,特别是使用基于纳米医学的递送系统作为应对当前传染病治疗挑战的新工具。此外,本文在汇编各种研究报告的同时,还包括制剂考量、渗透机制和已报道的专利。
尽管新技术和递送系统不断涌现,但仍需要朝着正确的方向努力,以应对这一全球性挑战。
