A variety of dosage forms have come into the market, where soft capsule receive a warm welcome for high bioavailability, attractive appearance, portability and other advantages. But in the drying process of soft capsules, the existence of deformation, gravure pill, adhesion, rupture, crystallization and slow dissolution, have seriously affected the manufacturing and quality of product. So it’s necessary to study the drying process to improve quality of product and manufacturing. This paper aims at studying the drying process of Ibuprofen soft capsules using quality by design (QbD) principles and identifying all key drying process parameters which may affect product quality. Controlling these parameters will reduce the risk of drying process that has impact? on product quality. In the course of the study, first, analysis of the reference list drug was performed and the quality target product profile (QTPP) for the ANDA product was determined. The critical quality attributes (CQAs) were evaluated and the CQAs which may be affected by drying process are identified, i.e. shell moisture and fill moisture. These two CQAs were evaluated in the drying process study. Then, based on the analysis of several existing drying technology and combined with the existing workshop equipment, we established a controllable drying process, namely ventilation for drying in the drying room. After that, a preliminary assessment of the risk of process parameters impact on CQAs was conducted. The risk of tunnel humidity and tunnel wind speed impact on the product quality was unacceptable, further research is needed to reduce the risk. The risks of impact of tumble humidity, tumble wind speed,
