Skin diseases pose challenges in treatment due to the skin's complex structure and protective functions. Topical drug delivery has emerged as a preferred method for treating these conditions, offering localized therapy with minimal systemic side effects. However, the skin's barrier properties frequently limit topical treatments' efficacy by preventing drug penetration into deeper skin layers. In recent years, laser-assisted drug delivery (LADD) has gained attention as a promising strategy to overcome these limitations. LADD involves using lasers to create microchannels in the skin, facilitating the deposition of drugs and enhancing their penetration into the target tissue. Several lasers, such as fractional CO, have been tested to see how well they work at delivering drugs. Despite the promising outcomes demonstrated in preclinical and clinical studies, several challenges persist in implementing LADD, including limited penetration depth, potential tissue damage, and the cost of LADD systems. Furthermore, selecting appropriate laser parameters and drug formulations is crucial to ensuring optimal therapeutic outcomes. Nevertheless, LADD holds significant potential for improving treatment efficacy for various skin conditions, including skin cancers, scars, and dermatological disorders. Future research efforts should focus on optimizing LADD techniques, addressing safety concerns, and exploring novel drug formulations to maximize the therapeutic benefits of this innovative approach. With continued advancements in laser technology and pharmaceutical science, LADD has the potential to revolutionize the field of dermatology and enhance patient care.
皮肤疾病的治疗具有挑战性,这是由于皮肤的复杂结构和保护功能。局部药物递送已成为治疗这些疾病的首选方法,它提供了局部治疗,且全身副作用最小。然而,皮肤的屏障特性经常通过阻止药物渗透到更深的皮肤层来限制局部治疗的效果。近年来,激光辅助药物递送(LADD)作为一种有前途的策略引起了人们的关注,以克服这些限制。LADD 涉及使用激光在皮肤中创建微通道,促进药物的沉积并增强其渗透到目标组织的能力。已经测试了几种激光,如分数 CO2 激光,以了解它们在药物递送方面的效果如何。尽管在临床前和临床研究中显示出了有希望的结果,但在实施 LADD 时仍然存在一些挑战,包括有限的渗透深度、潜在的组织损伤和 LADD 系统的成本。此外,选择合适的激光参数和药物配方对于确保最佳治疗效果至关重要。然而,LADD 为改善各种皮肤状况的治疗效果提供了巨大的潜力,包括皮肤癌、疤痕和皮肤病。未来的研究工作应集中在优化 LADD 技术、解决安全问题以及探索新的药物配方上,以最大限度地发挥这种创新方法的治疗效益。随着激光技术和药物科学的不断进步,LADD 有可能彻底改变皮肤病学领域并改善患者的护理。
