          摘   要  目的  采用立体光刻成型(SLA)3D打印技术制备盐酸文拉法辛-盐酸氟西汀多层片,并进行质量评价和体外释放考察。
          方法  以盐酸文拉法辛/盐酸氟西汀、光聚合单体PEGDA 400、致孔剂PEG 300、光引发剂TPO和光吸收剂柠檬黄等组成处方,采用
          SLA型3D打印技术制备外径10 mm、内径5 mm、厚度6 mm的盐酸文拉法辛-盐酸氟西汀多层片,然后对其外观、三维尺寸、重量
          均匀度、药物含量、内部结构特征以及体外释放特性进行考察。结果  该多层片的打印成型性良好,边缘平滑圆整,大小、厚度均
          匀,外径、内径、厚度分别为(10.06±0.26)、(4.94±0.06)、(5.80±0.12) mm(RSD分别为2.58%、1.21%、2.07%,n=20);重量差异符
          合药典要求;两药含量分别为(7.96±0.09)、(11.26±0.46) mg/片。X射线衍射表征和扫描电镜表征结果显示,该多层片中两种药
          物分子以无定形结构存在,盐酸文拉法辛层溶出后产生明显的孔道结构,而盐酸氟西汀层未出现孔道结构。盐酸文拉法辛层和盐
          酸氟西汀层在 24 h 时的累积释放率分别为(91.88±0.94)%、(106.25±1.28)%,符合 Rigter-Peppas 释放模型。结论  本研究采用
          SLA型3D打印技术成功制备了盐酸文拉法辛-盐酸氟西汀多层片,该多层片成型性良好,且符合Rigter-Peppas释放模型。

          ABSTRACT    OBJECTIVE  To  prepare  venlafaxine  hydrochloride  and  fluoxetine  hydrochloride  multiplayer  tablets  by
          stereolithography (SLA)  3D  printing  technology,  and  to  conduct  its  quality  evaluation  and  in  vitro  release  investigation.
          METHODS  Using  venlafaxine  hydrochloride/fluoxetine  hydrochloride,  photopolymerization  monomer  PEGDA  400,  porogen  PEG
          300, photoinitiator TPO and light absorber citrine as formulation, SLA 3D printer technology was employed to prepare venlafaxine
          hydrochloride  and  fluoxetine  hydrochloride  multiplayer  tablets,  with  outer  diameter  of  10  mm,  inner  diameter  of  5  mm,  and
          thickness  of  6  mm.  Moreover,  the  tablets’  appearance,  three-dimensional  dimensions,  weight  uniformity,  drug  content,  internal
          structural  characteristics  and  in  vitro  release  characteristics  were  all  investigated.  RESULTS  The  multilayer  tablets  had  good
          printing  formability,  smooth  and  round  edges,  and  uniform  size  and  thickness;  the  outer  diameter,  inner  diameter  and  thickness
          were (10.06±0.26), (4.94±0.06), (5.80±0.12)  mm (RSD=2.58%,  1.21%,  2.07%,n=20),  and  the  weight  difference  all  met
          the  requirements.  The  contents  of  venlafaxine  hydrochloride  and  fluoxetine  hydrochloride  were (7.96±0.09)  and (11.26±0.46)
          mg/tablet, respectively. The results of X-ray diffraction and scanning electron microscopy characterization showed that the two drug
          molecules  in  the  multilayer  film  existed  in  an  amorphous  structure;  after  the  dissolution  of  the  venlafaxine  hydrochloride  layer,  a
          clear pore structure was formed, while the fluoxetine hydrochloride layer did not show any pore structure. According to the release
          curve,  24  h  accumulative  release  rates  of  venlafaxine  hydrochloride  layer  and  fluoxetine  hydrochloride  layer  were(91.88±0.94)%
          and (106.25±1.28)%,  which  were  in  line  with  Rigter-Peppas  release  model.  CONCLUSIONS  This  study  successfully  prepared
          venlafaxine  hydrochloride  and  fluoxetine  hydrochloride  multilayer  tablets  using  SLA  3D  printing  technology;  the  multilayer  tablets
                                                              have  the  advantages  of  excellent  printing  formability,  which
