To optimize the formula and preparation technology of Ruhe dispersible tablets.Method:The disintegration time and the appearance were observed to screen the optimal preparation technology of Ruhe dispersible tablets by uniform experiment. Result:The optimized formula of Ruhe dispersible tablets was as follows;38%extract powder,47%MCC,8%L-HPC,4%CMSNa, 2%PVPP and 2%aerosil.The optimized dispersible tablets could disintegrate uniformly in 3 minutes,showing promising distribution homogeneity.Conclusion:The optimized formula is reasonable,and the...
