Optimization of Formulation of Erhuangsan Bletillae Rhizoma Gelatin Sustained Release Double-layer Membrane by Central Composite Design-response Surface Methodology
With Bletillae Rhizoma gelatin as the main film-forming materials
Erhuangsan was developed into a sustained-release double-layer membrane for vagina.
Method:
2
Taking hydroxypropyl methyl cellulose(HPMC) and Bletillae Rhizoma gelatin as the film-forming materials of Coptidis Rhizoma-Alumen membrane layer
sodium carboxymethyl cellulose(CMC-Na) and Bletillae Rhizoma gelatin as the film-forming materials of Catechu membrane layer
glycerol as plasticizer
Erhuangsan Bletillae Rhizoma gelatin sustained release double-layer membrane was prepared.Central composite design-response surface methodology was used to optimize formulation of this preparation with appearance quality score
adhesion force and
in vitro
cumulative release as indexes.
Result:
2
Optimum formulation of Catechu membrane layer was 1.61% of CMC-Na
3.81% of Bletillae Rhizoma gelatin and 8.49% of glycerol; optimum formulation of Coptidis Rhizoma-Alumen membrane layer was 1.15% of HPMC
3.41% of Bletillae Rhizoma gelatin and 10.02% of glycerol.
Conclusion:
2
The optimized formulation is stable and feasible.Erhuangsan Bletillae Rhizoma gelatin sustained release double-layer membrane has characteristics of advanced dosage form and convenient use
providing a feasible modern Chinese medicine preparation for treatment of cervical cancer
and accumulating data for the research of Chinese medicine film agent.
