Pharmaceutical API Process Development and Design

By Kamal Kuriyan

Imperial College



Published on


API process development involves selection, preliminary design and scale-up of the equipment used to carry out the recipe for producing the desired form of the drug substance. This course will cover selected topics in API process development. Operations studied include batch reaction, evaporation, crystallization and filtration. The material is organized into two parallel tracks. One track introduces the basic concepts, equipment types and modes of operation for common API unit operations. The other track incorporates a set of applications demonstrating the use of simulation models and tools in solving design problems.
