摘要

背景:美洛昔康水溶性低，影响溶出度和吸收水平。目的:制备基于非离子表面活性剂组合的自纳米乳化给药体系(SNEDDS)，并利用DDsolver程序评价其释放动力学模型。方法:根据美洛昔康的溶解度选择油、表面活性剂和助表面活性剂。结果:最佳配方为:10%蓖麻油、70%表面活性剂(80:生色团RH 40∶1:1)、20% PEG 400可形成SNEDDS，其透过率为99.84±0.04%，乳化时间为15.47±0.72秒，液滴粒径小于50 nm。优化后的配方稳定，耐各种稀释度和pH值，溶解效率(DE0-60)比非snedds的美洛昔康提高5.27倍。美洛昔康符合Korsmeyer-Peppas释放动力学，而美洛昔康SNEDDS符合Hixon-Crowell模型。结论:表面活性剂复合制剂的最佳处方可提高美洛昔康的体外溶出度。

Meloxicam self-nano-emulsifying drug delivery system with surfactants combination: Formulation and in vitro release model

Background: Meloxicam has low water solubility, which affects the dissolution and level of absorption. Objective: The study aimed to develop a self-nano-emulsifying drug delivery system (SNEDDS) based on a non-ionic surfactant combination and evaluate the release kinetics model using the DDsolver program. Methods: Oil, surfactant, and co-surfactant were selected based on the solubility of meloxicam. Results: The best formula showed that 10% of castor oil, 70% of surfactant (tween 80: chromophore RH 40 in 1:1), and 20% of PEG 400 could develop SNEDDS with the 99.84±0.04% percentage of transmittance, 15.47±0.72 sec emulsifying time, and below 50 nm droplet size. The optimised formula is also stable and resistant to various dilutions and pH The dissolution efficiency (DE0-60) reveals a 5.27-fold increase compared to non-SNEDDS meloxicam. Meloxicam follows Korsmeyer-Peppas release kinetics, while meloxicam SNEDDS follows the Hixon-Crowell model. Conclusion: The best formula of SNEDDS consisting of a surfactant combination generate improvement in vitro dissolution of meloxicam.
