Pain is a widespread and growing health problem worldwide that exerts a considerable social and economic impact on both patients and healthcare systems and, therefore, on society in general. Although current treatment modalities include a wide variety of pharmacological and non-pharmacological approaches, due to the complexity of pain and individual differences in clinical response these options are not always effective in mitigating and relieving pain. In addition, some pain drugs such as non-steroidal anti-inflammatory drugs (NSAIDs), local anesthetics and opioids show several unfavorable side effects. Therefore, current research advances in this medical field are based on the development of potential treatments to address many of the unmet needs and to overcome the existing limitations in pain management. Nanoparticle drug delivery systems present an exciting opportunity as alternative platforms to improve efficacy and safety of medications currently in use. Herein, we review a broad range of nanoparticle formulations (organic nanostructures and inorganic nanoparticles), which have been developed to encapsulate an array of painkillers, paying special attention to the key advantages that these systems offer, (compared to the use of the free drug), as well as to the more relevant results of preclinical studies in animal models. Additionally, we will briefly discuss the impact of some of these nanoformulations in clinical trials.

纳米颗粒疗法在疼痛管理中的最新进展和挑战

疼痛是世界范围内广泛且日益严重的健康问题,它对患者和医疗系统以及整个社会都产生了相当大的社会和经济影响。尽管当前的治疗方式包括多种药理学和非药理学方法,但由于疼痛的复杂性和临床反应的个体差异,这些选择并不总是有效地缓解和缓解疼痛。此外,一些止痛药,例如非甾体抗炎药(NSAIDs),局部麻醉药和阿片类药物显示出几种不良副作用。因此,该医学领域的当前研究进展基于潜在疗法的开发,以解决许多未满足的需求并克服疼痛管理中的现有局限性。纳米颗粒药物输送系统作为替代平台提供了令人兴奋的机会,以提高当前使用的药物的功效和安全性。本文中,我们回顾了广泛的纳米颗粒制剂(有机纳米结构和无机纳米颗粒),它们被开发为封装多种止痛药,并特别注意这些系统提供的关键优势(与使用游离药物相比) ),以及动物模型中临床前研究的更多相关结果。此外,我们将简要讨论其中一些纳米制剂在临床试验中的影响。我们回顾了广泛的纳米颗粒制剂(有机纳米结构和无机纳米颗粒),它们被开发为封装多种止痛药,并特别注意这些系统提供的关键优势(与使用游离药物相比),以及动物模型中临床前研究的更多相关结果。此外,我们将简要讨论其中一些纳米制剂在临床试验中的影响。我们回顾了广泛的纳米颗粒制剂(有机纳米结构和无机纳米颗粒),它们被开发为封装多种止痛药,并特别注意这些系统提供的关键优势(与使用游离药物相比),以及动物模型中临床前研究的更多相关结果。此外,我们将简要讨论其中一些纳米制剂在临床试验中的影响。
