Despite growing prevalence and incidence, the management of gout remains suboptimal. The intermittent nature of the gout makes the long-term urate-lowering therapy (ULT) particularly important for gout management. However, patients are reluctant to take medication day after day to manage incurable occasional gout flares, and suffer from possible long-term toxicity. Therefore, a safe and easy-to-operate drug delivery system with simple preparation for the long-term management of gout is very necessary. Here, a chitosan-containing sustained-release microneedle system co-loaded with colchicine and uricase liposomes were fabricated to achieve this goal. This microneedle system was confirmed to successfully deliver the drug to the skin and maintain a one-week drug retention. Furthermore, its powerful therapeutic potency to manage gout was investigated in both acute gouty and chronic gouty models. Besides, the drug co-delivery system could help avoid long-term daily oral colchicine, a drug with a narrow therapeutic index. This system also avoids mass injection of uricase by improving its stability, enhancing the clinical application value of uricase. In general, this two-drug system reduces the dosage of uricase and colchicine and improves the patient's compliance, which has a strong clinical translation.
尽管痛风的患病率和发病率不断上升,但其管理仍不尽人意。痛风的间歇性使得长期降尿酸治疗(ULT)对痛风管理尤为重要。然而,患者不愿日复一日地服药来应对无法治愈的偶尔痛风发作,且担心可能的长期毒性。因此,开发一种安全、易于操作且制备简单的用于痛风长期管理的给药系统非常必要。在此,制备了一种共载秋水仙碱和尿酸酶脂质体的含壳聚糖缓释微针系统以实现这一目标。该微针系统被证实能够成功将药物递送至皮肤并保持一周的药物滞留。此外,在急性痛风和慢性痛风模型中研究了其治疗痛风的强大效力。此外,该药物共递送系统有助于避免长期每日口服秋水仙碱这种治疗指数较窄的药物。该系统还通过提高尿酸酶的稳定性避免了大量注射尿酸酶,增强了尿酸酶的临床应用价值。总体而言,这种双药系统减少了尿酸酶和秋水仙碱的用量,提高了患者的依从性,具有很强的临床转化价值。
