Drying has been conducted since time immemorial with the main purpose of preserving food and agricultural produce. This chapter provides a concise history of drying of pharmaceutical products. The Chinese book on roots and grasses Pen T'Sao, written by Emperor Shen Nung as early as 2500 BC, mentioned as many as 365 drugs obtained from dried parts of medicinal plants, many of which are still in use even today. The chapter also gives brief histories of some popular drying techniques for drugs and other relevant molecules. The selected drying technologies discussed are: Freeze drying, spray drying, fluidized, bed drying, and supercritical drying. Spray drying is probably the most mature alternative technology to freeze drying and can be applied to the production of many pharmaceutical products.
