摘要: 本试验研制伊维菌素纳米乳透皮制剂,并对其理化性能、稳定性、体外药物释放及透皮性能进行评价。采用三元相图筛选不同载药量的纳米乳,确定最佳载药量;采用响应面优化设计筛选纳米乳处方,考察了伊维菌素纳米乳的平均粒径、电位、形态、pH、黏度等性能;分别采用透析袋法和Franz扩散池法比较伊维菌素纳米乳透皮制剂与市售伊维菌素皮肤涂剂的体外释放行为和透皮性能。结果显示,载药量为2.00%时,纳米乳区域最大、最稳定;获得的优选处方为聚氧乙烯蓖麻油 :二乙二醇单乙基醚 :油酸乙酯 :伊维菌素 :水=26 :12 :7: 2: 53;所得伊维菌素纳米乳的平均粒径为18 nm;伊维菌素纳米乳在室温条件和4 ℃冰箱中保存1年仍稳定;其24 h皮肤累积渗透量和滞留量分别是市售伊维菌素皮肤涂剂的3.24和2.05倍。研究结果表明,研制的新型伊维菌素纳米乳透皮制剂具有制备工艺简便、稳定性好、透皮性能好等优点,具有很好的应用前景。

Abstract: The aim of the study was to prepare ivermectin nanoemulsion for transdermal drug delivery.The physicochemical property,stability,in vitro drug release and transdermal property were evaluated.The optimal drug loading with good stability and larger nanoemulsion region was investigated by ternary phase diagram.The response surface methodology was used for selecting the optimal prescription.The average diameter,zeta potential,morphology,pH and viscosity were also investigated.In vitro drug release and transdermal property of ivermectin nanoemulsion and market ivermectin skin varnish were compared by dialysis bags and Franz diffusion cells.The nanoemulsion region was largest and most stable when the drug loading was 2.00%.The optimal prescription was Cremophor EL-35 :Transcutol HP :ethyl oleate :ivermectin :H2O=26: 12: 7: 2: 53 and its average diameter was 18 nm.The ivermection nanoemulsion was stable when it was stored in 4 ℃ refrigerator and room temperature for 1 year.The cumulative permeation and retention of ivermectin nanoemulsion in 24 h were 3.24 and 2.05 times over the commercially available varnish,respectively.These results indicated that the ivermectin nanoemulsion had the advantages of simple preparation process,excellent stability and transdermal property,and had good application prospects.
