Abstract
This chapter presents an overview of the perspective chapter on pharmaceutical drying within the context of drug manufacturing. It explores the significance of pharmaceutical drying in ensuring the stability and efficacy of drug products. The chapter begins by defining pharmaceutical drying and emphasizing its importance in the manufacturing process. Various methods of pharmaceutical drying, including air drying, vacuum drying, freeze-drying, and spray drying, are discussed, and a comparison between these methods is provided. Factors that influence pharmaceutical drying, such as physical and chemical properties of the product, drying temperature, drying time, pressure, humidity, and solvent properties, are examined. The chapter also highlights the challenges associated with pharmaceutical drying, including product stability and degradation, loss of potency, residual solvents, and the formation of amorphous or crystalline solids. Strategies to overcome these challenges, such as process optimization, the use of drying aids, control of drying parameters, and formulation considerations, are explored. Quality control measures in pharmaceutical drying, including the monitoring of residual moisture and solvent levels, characterization of dried products, and adherence to regulatory guidelines, are discussed.
