Abstract

Polymeric nanofibers fabricated by electrospinning either blank (PVA) or loaded with minoxidil sulphate have yielded optimum fibers with an average diameter 273 nm, and 511 nm, respectively. Thermal analysis of nanofibers indicated no chemical interaction. The NMR spectrum confirmed stability of nanofiber as there were no interactions between functional groups. Prepared nanofibers showed a 47.4% encapsulation efficiency and 73% yield. In vitro drug release of minoxidil sulphate from nanofiber exhibited an initial burst release followed by a slower release pattern. Stability studies revealed that minoxidil nanofiber was stable if stored at room temperature and protected from light with only loss of 9.6% of its nominal concentration within 6 months. As a result, the prepared solid/colored formula serves as an ideal formulation for such instable drug in liquid formula taking the advantage of the attractiveness of beauty colored coverage, and the simple, and non-tousled application.

摘要

静电纺丝制备的聚合物纳米纤维,无论是空白(PVA)还是载有硫酸米诺地尔的纳米纤维,分别得到了平均直径为 273nm 和 511nm 的最佳纤维。纳米纤维的热分析表明没有化学相互作用。核磁共振谱证实了纳米纤维的稳定性,因为官能团之间没有相互作用。制备的纳米纤维的包封效率为 47.4%,产率为 73%。硫酸米诺地尔从纳米纤维中的体外药物释放表现出初始突释释放,随后是较慢的释放模式。稳定性研究表明,硫酸米诺地尔纳米纤维在室温下储存并避光保存时是稳定的,在 6 个月内仅损失其名义浓度的 9.6%。因此,所制备的固/彩色配方作为不稳定药物在液体配方中的理想配方,利用美容彩色覆盖物的吸引力,以及简单、不凌乱的应用。
