Abstract

Aim: The aim of this study was preparation of a self-emulsifying drug delivery system (SEEDS) containing metformin hydrochloride.

Methods: Hydrophobic ion paired complexes were prepared by electrostatic interaction between metformin and sodium lauryl sulphate (SLS). The nanodroplets were optimised using two-level full factorial methodology and their morphology were examined. In vitro release of metformin from SEDDS was evaluated in simulated gastric and intestinal fluids. Finally, the ex-vivo efficacy of the optimised formulation in enhancing the intestinal permeability of metformin was evaluated using non-everted intestinal sac.

Results: The data revealed that in weight ratio 1:4(metformin: SLS), the highest recovery was achieved. The physico-chemical properties of the optimised nano-droplets including size, polydispersity index (PdI), zeta potential, and loading efficiency (%) were 192.33 ± 9.9 nm, 0.275 ± 0.051; -1.52 mV, and 93.75 ± 0.77% (w/w), respectively.

Conclusions: The data obtained from the intestinal transport study demonstrated that SEDDS can significantly enhance the oral permeability of the compound.

疏水离子对络合提高盐酸二甲双胍口服生物利用度的自乳化给药系统(SEDDS)的制备与表征。

目的:制备盐酸二甲双胍自乳化给药系统。方法:二甲双胍与十二烷基硫酸钠(SLS)静电相互作用制备疏水离子配对配合物。采用两水平全因子方法对纳米液滴进行优化，并对其形态进行了检测。在模拟胃液和肠液中评估了SEDDS中二甲双胍的体外释放。最后，采用非外翻肠囊评价优化后的配方提高二甲双胍肠通透性的体外疗效。结果:二甲双胍:SLS质量比为1:4时，回收率最高。优化后的纳米液滴的理化性质包括粒径、PdI、zeta电位和负载效率(%)分别为192.33±9.9 nm、0.275±0.051 nm;分别为-1.52 mV和93.75±0.77% (w/w)。结论:肠道转运研究数据表明，SEDDS可显著提高化合物的口服通透性。

期刊介绍： The Journal of Microencapsulation is a well-established, peer-reviewed journal dedicated to the publication of original research findings related to the preparation, properties and uses of individually encapsulated novel small particles, as well as significant improvements to tried-and-tested techniques relevant to micro and nano particles and their use in a wide variety of industrial, engineering, pharmaceutical, biotechnology and research applications. Its scope extends beyond conventional microcapsules to all other small particulate systems such as self assembling structures that involve preparative manipulation. The journal covers: Chemistry of encapsulation materials Physics of release through the capsule wall and/or desorption from carrier Techniques of preparation, content and storage Many uses to which microcapsules are put.
