Spray drying is a rapid, robust, reproducible, and scalable process. Since its invention in 1872, it has been applied in numerous applications for poorly soluble compounds and high drug-loaded products. Pharmaceutical spray drying is a process to create dry powder out of a liquid solution, and is used in the production of numerous dry powder products including active pharmaceutical ingredient (APIs) penicillin, enzymes, excipients, bulk agents, controlled drug release formulations, and more.
