摘要: 【目的】制备一种可用于透皮给药的乙酰氨基阿维菌素混合胶束(eprinomectin mixed micelles,EPR-MMs)。【方法】采用薄膜分散法,以聚氧乙烯氢化蓖麻油40和壬基酚聚氧乙烯醚40为载体材料制备EPR-MMs,通过单因素法考察EPR-MMs的粒径、多分散性指数(PDI)、包封率、载药量以及稳定性等指标,并对表面活性剂比、药辅比、水化转速以及水化时间等参数进行筛选和优化,确立最佳处方和工艺参数。采用芘荧光探针法测定EPR-MMs的临界胶束浓度(CMC),通过透射电镜和傅立叶变换红外光谱(FT-IR)分析对其微观结构进行表征;以市售浇泼剂作为对照,采用改良的Franz扩散池考察EPR-MMs的体外透皮性能。【结果】试验筛选出的EPR-MMs最佳工艺处方为:表面活性剂比为20∶1、药辅比为1∶9、水化转速为1 200 r/min、水化时间为4 h。以筛选的最佳工艺条件制备的EPR-MMs临界胶束浓度为11.596 μg/mL,其在透射电镜下为类球形,粒径大小适宜,形态良好。通过FT-IR分析证实药物被包载在胶束中。稳定性研究表明制备的EPR-MMs在室温下放置7 d稳定性良好。体外透皮结果显示,EPR-MMs单位面积透皮累积渗透量为44.26 μg/cm2,约为浇泼剂的3.82倍,渗透速率为浇泼剂的3.90倍。【结论】试验成功制备了稳定且粒径适宜的EPR-MMs,并通过多项表征方法验证了其理化性质,表现出良好的体外释药特性,相较于市售浇泼剂具有更高的透皮速率和渗透量。

Abstract: 【Objective】 The aim of this study was to prepare a kind of eprinomectin mixed micelle (EPR-MMs) which could be used for transdermal adminstration.【Method】 EPR-MMs were prepared by membrane hydration method using PEG-40 hydrogenated castor oi and nonyl phenol polyoxyethylene ether 40 as carriers.The particle size,polydispersity index (PDI),encapsulation efficiency,loading efficiency,and stability of EPR-MMs were evaluated through single-factor examination.Parameters such as the surfactant ratio,drug surfactant ratio,hydration rotation speed,and hydration time were screened and optimized to establish the best prescription and process parameters.The critical micelle concentration (CMC) was determined using the pyrene fluorescence probe method.The microstructure was characterized by transmission electron microscopy and Fourier transform infrared spectroscopy (FT-IR).The in vitro transdermal properties of EPR-MMs were investigated by using Franz diffusion cell,with a commercial pour-on agent as the control.【Result】 The optimum process prescription of EPR-MMs was as follows:Surfactant ratio was 20∶1,drug and surfactant ratio was 1∶9,hydration speed was 1 200 r/min and hydration time was 4 h.The CMC of EPR-MMs prepared under the optimal screening conditions was 11.596 μg/mL.EPR-MMs was spheroid under transmission electron microscope,with suitable particle size and good morphology.FT-IR analysis confirmed that the drug was encapsulated in the micelle.Stability studies showed that the prepared EPR-MMs had good stability when placed at room temperature for 7 d.In vitro permeation results demonstrated that the cumulative permeation amount per unit area of EPR-MMs was 44.26 μg/cm2,which was about 3.82 times that of the pour-on,and the penetration rate was 3.90 times that of the pour-on. 【Conclusion】 The stable EPR-MMs with suitable particle size was successfully prepared,and its physicochemical properties were verified by multiple characterization methods,showing good in vitro release characteristics,and higher transdermal rate and permeability than the commercial pour-on.
