摘 要 目的 制备共载小檗碱/胡椒碱自微乳给药系统(BBR/PIP-SMEDDS),评价其理化性质、体外释药及药动学特征。方法
通过外翻肠囊法确定制剂中小檗碱(BBR)和胡椒碱(PIP)的载药质量比;通过溶解度检测、相容性评价和伪三元相图分别确定油
相、乳化剂和助乳化剂;以油相用量、乳化剂-助乳化剂质量比为因素,粒径和Zeta电位的综合评分为响应值,采用星点设计-效应
面法优化空白自微乳给药系统(SMEDDS)的处方并验证;按最优处方,在磁力搅拌下加入过量 BBR、PIP 原料药,制得 BBR/PIP-
SMEDDS,对其理化性质、体外释药行为、大鼠体内药动学特征进行考察。结果 BBR和PIP的载药质量比为1∶1,最优处方为油相
(油酸乙酯)占18.54%,乳化剂(吐温-80)占52.16%,助乳化剂(聚乙二醇400)占29.30%。3次验证实验显示,所得空白SMEDDS的
平均粒径为(16.49±0.49)nm,Zeta电位为(-16.22±0.77)mV,综合评分为0.97分,与预测值(0.95分)的相对偏差为2.11%。所制
BBR/PIP-SMEDDS 为水包油型微乳,为金黄色油状液体,呈圆球状,平均粒径为(32.90±0.38)nm,Zeta 电位为(-19.17±0.70)
mV;BBR的包封率为(90.44±0.88)%,载药量为(10.18±0.17)mg/g;PIP的包封率为(87.48±1.13)%,载药量为(9.41±0.17)mg/g
(n=3)。BBR/PIP-SMEDDS低温(4 ℃)避光、离心、稀释条件下稳定性较好。体外释药结果显示,制备成SMEDDS后,BBR在模
拟肠液中24 h时的累积释放百分率明显高于原料药。大鼠药动学研究结果表明,BBR/PIP-SMEDDS的峰浓度、药时曲线下面积
(AUC0-t )分别是原料药的4.61、7.07倍,相对生物利用度为707.484%。结论 成功制得BBR/PIP-SMEDDS,所得制剂的体外释放和
生物利用度均较原料药有较大提升。

ABSTRACT OBJECTIVE To prepare berberine/piperine co-loaded self-microemulsion drug delivery system (BBR/PIP-
SMEDDS), evaluate its physicochemical properties, in vitro release and pharmacokinetic characteristics. METHODS The drug
loading mass ratio of berberine (BBR) and piperine (PIP) in the preparation was determined by the everted intestinal sac method.
The oil-phase, emulsifier and co-emulsifier were determined by solubility detection, compatibility evaluation and pseudo-ternary
phase diagram, respectively. The formulation of blank self-microemulsion drug delivery system (SMEDDS) was optimized and
verified by central composite design-response surface methodology with the amount of oil-phase and the mass ratio of emulsifier to
co-emulsifier as factors, and the comprehensive score of particle size and Zeta potential as response value. According to the optimal
prescription, BBR/PIP-SMEDDS was prepared by adding excessive BBR and PIP raw materials under magnetic stirring, and its
physicochemical properties, in vitro release behavior and pharmacokinetic characteristics in rats were investigated. RESULTS The
drug loading mass ratio of BBR and PIP was 1∶1. The optimal prescription included oil-phase (ethyl oleate) accounted for 18.54%,
emulsifier (Tween-80) accounted for 52.16%, and co-emulsifier (polyethylene glycol 400) accounted for 29.30%. Three
verification experiments showed that the average particle size of blank SMEDDS was (16.49±0.49) nm; the Zeta potential was
(-16.22±0.77) mV; the comprehensive score was 0.97, the relative deviation of which from the predicted value (0.95) was
2.11%. The prepared BBR/PIP-SMEDDS was an oil-in-water microemulsion, which was a golden yellow oily liquid with a
spherical shape. The average particle size was (32.90±0.38)
