The article discusses the importance of pharmaceutical powder drying and the application of different particle engineering technologies, emphasizing the advancement and potential applications of drying in drug delivery systems. It provides information on commercial, regulatory, and scale-up strategies to help readers, researchers, and industrialists address key issues in drying operations.
Drying is an indispensable operation in the preparation of pharmaceutical powders and always remained one of the energetic tasks in the pharmaceutical industry. Improving the stability, solubility, and dissolution of pharmaceutical products are being prime objectives of the drying process, intending to produce the products loving the dry state. Although there are voluminous literatures available concerning drying operations, there is scant information available regarding the applicability of drying in drug delivery and process scale-up. The current communication embodies the different particle engineering technologies of drying viz. spray-, freeze-, and spray-freeze drying. In addition, potential uses of drying in the taste masking, and the development of inhalable powders presented briefly. Recent advancements in the drying of novel drug delivery systems is the major focus of the present review. In our opinion, the commercial aspects, regulatory guidelines, and scale-up strategies presented herein provide an opportunity to readers, researchers, and industrialists to ruin the critical issues during drying operations and aid in developing quality pharmaceutical technologies.
