摘要:

吲哚美辛是一种非甾体抗炎药,具有解热镇痛和消炎等药理作用。 然而,吲哚美辛的低水溶性、低生物利用率及其对胃肠道的刺激,严重制约了其在临床上的应用。 针对上述问题,以尤特奇RS100、聚乙烯吡咯烷酮(PVP K30)为缓释基质,利用静电纺丝技术,制备了一种具有双相释放药物性能的载吲哚美辛核壳结构纳米纤维。 通过正交设计实验优化的制备工艺参数为电压16.94 kV,接收距离11.02 cm,流速1.44 mL/h。 该载药纳米纤维直径多分布于600~800 nm间,平均直径为(675±177) nm,形貌良好,呈现同轴结构,有利于吲哚美辛的双相释放。 体外释放及初步药效学研究表明该载药纳米纤维能够持续释放25 h,仅需不到2 h即可释放出累计释放量的50%,具有速释、缓释双相释药性能,抗炎镇痛作用优良,能够有效促进伤口愈合。 期望本研究能够为医用新型创伤敷料的发展提供参考。

Abstract:

Indomethacin is a nonsteroidal anti-inflammatory drug with pharmacologic effects such as antipyretic and analgesic and anti-inflammatory. However, indomethacin's low water solubility, low bioavailability and its irritation to the gastrointestinal tract have severely limited its clinical application. To address these problems, an indomethacin-loaded core-shell structured nanofiber with biphasic drug release properties was prepared by electrostatic spinning using Eutectic RS100 and polyvinylpyrrolidone (PVP K30) as a slow-release matrix. The parameters of the preparation process optimized by orthogonal design test were voltage 16.94 kV, receiver distance 11.02 cm and flow rate 1.44 mL/h. The diameter of the drug-loaded nanofibers was mostly distributed between 600~800 nm, with an average diameter of (675±177) nm, which had good morphology and coaxial structure, which was conducive to the biphasic release of indomethacin. In vitro release and preliminary pharmacodynamic studies have shown that the drug-loaded nanofibers can be continuously released for about 25 h, and release 50% of the cumulative release in less than 2 h, which has the performance of immediate-release and sustained-release biphasic release, excellent anti-inflammatory and analgesic effects, and can effectively promote wound healing. It is expected that this study can provide a reference for the development of new medical wound dressings.
