Abstract

OBJECTIVE:

To select the best froming techniques for Compound Tall Gastrodia Tuber drop pills.

METHODS:

According to the factors that affect the quality of drop pill, we selected four factors as temperature of drop solution, the variety of matrix, the ratio between drug and matrix, the dropping distance, and then we selected the RSD of weight of dripping pills and the roundness as index examination.

RESULTS:

The optimum techniques as follows: the ratio between drug and matrix was 3 : 7, the temperature of drug solution was 80 degrees C, the dropping distance was 1 cm, the composition of matrix was PEG4000: PEG6000 = 1 : 1. The method adopted was steady and feasible.

CONCLUSION:

It's feasible to seek the optimum techniques making Compound Tall Gastrodia Tuber drop pills by uniform design method.
