Optimization of prescriptions for Yuanhu Zhitong Orally Disintegrating Tablets based on central composite design-response surface methodology / 中草药

ABSTRACT

Objective To optimize the best prescription of Yuanhu Zhitong Oral Disintegrating Tablets (YZODT). Methods Using the single factor test, the prescription of the tablets was optimized by central composite design-response surface methodology (CCD-RSM) with the tablet wetting time and the disintegration time limit as evaluation index, so as to determine the best preparation process. Results The dosages of the optimized prescription of MCC, L-HPC, and PVPP were 30%, 15%, and 5%, respectively. The average disintegration time of the optimized YZODT was 42.89 s, and the deviation from the predicted value was 3.27%. Conclusion The optimized YZODT has the advantages of fast disintegration, moderate hardness, convenient use, and simple process.
