Osteoarthritis is one of the foremost disabling disorders in the world. There is no definitive treatment to prevent the progression of osteoarthritis. Hence, palliative treatment aims at minimizing pain, disability and improving function, performance and quality of life. Oral administration of nonsteroidal anti-inflammatory drug is associated with number of adverse effects and reduced therapeutic efficacy. Intra-articular injection has been the preferred route of drug administration. However, the clearance of drug from the arthritic site, risk of infections, cost and the pain associated with frequent injections make this route highly non-compliant to patients. Since osteoarthritis is a chronic condition which requires treatment for prolonged duration, there is an urgent need for another administration route which circumvents the hindrances linked with intra-articular route. Transdermal route across the skin locally at the osteoarthritis site could help in surpassing the disadvantages associated with intra-articular route. However, traversing skin barrier and reaching the chondrocytes with sufficient amount of the drug is extremely difficult. Nanocarrier-based approaches could hold an answer to the said shortcomings owing to their reduced size, targeting tunability and site specificity. In this article, we discuss the pathophysiology of osteoarthritis, molecular targets, and utilization of nanocarrier-based approaches to strategize the treatment of osteoarthritis in a new direction, i.e. topical delivery of nanocarriers in osteoarthritis.

骨关节炎局部治疗中新型给药系统的探索

骨关节炎是世界上最严重的致残性疾病之一。没有明确的治疗方法可以预防骨关节炎的进展。因此,姑息治疗旨在最大限度地减少疼痛、残疾并改善功能、表现和生活质量。非甾体抗炎药的口服给药与不良反应的数量和疗效降低有关。关节内注射一直是首选的给药途径。然而,药物从关节炎部位的清除、感染的风险、成本以及与频繁注射相关的疼痛使得该途径对患者非常不顺应。由于骨关节炎是一种慢性疾病,需要长期治疗,迫切需要另一种给药途径来规避与关节内途径相关的障碍。在骨关节炎部位局部穿过皮肤的透皮途径可能有助于克服与​​关节内途径相关的缺点。然而,穿越皮肤屏障并使足够量的药物到达软骨细胞是极其困难的。基于纳米载体的方法可以解决上述缺点,因为它们尺寸更小、靶向可调性和位点特异性。在这篇文章中,我们讨论了骨关节炎的病理生理学、分子靶点,以及利用基于纳米载体的方法在一个新的方向上制定治疗骨关节炎的策略,即在骨关节炎中局部递送纳米载体。在骨关节炎部位局部穿过皮肤的透皮途径可能有助于克服与​​关节内途径相关的缺点。然而,穿越皮肤屏障并使足够量的药物到达软骨细胞是极其困难的。基于纳米载体的方法可以解决上述缺点,因为它们尺寸更小、靶向可调性和位点特异性。在这篇文章中,我们讨论了骨关节炎的病理生理学、分子靶点,以及利用基于纳米载体的方法在一个新的方向上制定治疗骨关节炎的策略,即在骨关节炎中局部递送纳米载体。在骨关节炎部位局部穿过皮肤的透皮途径可能有助于克服与​​关节内途径相关的缺点。然而,穿越皮肤屏障并使足够量的药物到达软骨细胞是极其困难的。基于纳米载体的方法可以解决上述缺点,因为它们尺寸更小、靶向可调性和位点特异性。在这篇文章中,我们讨论了骨关节炎的病理生理学、分子靶点,以及利用基于纳米载体的方法在一个新的方向上制定治疗骨关节炎的策略,即在骨关节炎中局部递送纳米载体。足够量的药物穿过皮肤屏障并到达软骨细胞是极其困难的。基于纳米载体的方法可以解决上述缺点,因为它们尺寸更小、靶向可调性和位点特异性。在这篇文章中,我们讨论了骨关节炎的病理生理学、分子靶点,以及利用基于纳米载体的方法在一个新的方向上制定治疗骨关节炎的策略,即在骨关节炎中局部递送纳米载体。足够量的药物穿过皮肤屏障并到达软骨细胞是极其困难的。基于纳米载体的方法可以解决上述缺点,因为它们尺寸更小、靶向可调性和位点特异性。在这篇文章中,我们讨论了骨关节炎的病理生理学、分子靶点,以及利用基于纳米载体的方法在一个新的方向上制定治疗骨关节炎的策略,即在骨关节炎中局部递送纳米载体。
