Abstract：?Objective To optimize?the forming process of Guizhi?Sleeping Capsules. Methods With hygroscopicity and the angle of repose as the evaluation indexes， the appropriate excipients were screened out， and the proportion of main medicine and excipients were optimized. With granulation condition， particle yield and molding rate as indicators， the optimal ethanol concentration was screened out; and the moisture absorption rate， repose angle， bulk density and critical relative humidity of particles were investigated. Results The optimal?molding process was that the powder was mixed with microcrystalline cellulose-soluble starch （6：3：1）; 75% ethanol was added to make soft material， granulated in 24 meshes， dried in vacuum （0.08–0.1 MPa， 60 ℃） for 4 hours; the whole granule was obtained. The repose angle of the granule was 29.30°; the moisture absorption rate was 8.95%; the bulk density was 0.444 8 g/mL; and the critical relative humidity was 74.27%. Conclusion?The forming process is reasonable and feasible， and can provide basis for the production of Guizhi?Sleeping Capsules.
