Implementation of PAT systems in pharmaceutical continuous production processes
Continuous production can overcome the time-consuming problems of batch production. In the classic batch system, once a drug is developed on the bench, lab scale has to be scaled-up to full commercial production. This is not only expensive, but it also prolongs the time-to-market. In a continuous line changing from development, pilot, clinical or commercial production just needs a longer run.
It is possible to use this line lights-out, 24 hours. If the industry is a bit reluctant, that is because the two main advantages of batch production (safety and quality) have to be assured. Since batch-production needs sampling and sometimes rejection of a whole batch, it is certainly worth the effort to innovate production methods in the pharmaceutical industry. It is clear the quality has to be designed into the product, therefore the production has to be well designed and the process has to be fully understood and controlled. This is exactly what the FDA wants to obtain by encouraging the industry to implement PAT (Process Analytical Technology) in their production lines. The drugs produced in such a line will be all of the same quality during the whole runtime and are immediately ready for the market.
Detecting and understanding what is happening during the process is one thing. The aim of this study is to use this data real-time. Implementing all process variables in a computer system will allow continuous feed-back to the production line.
