A thorough root cause analysis often reveals that compression issues such as capping, sticking and weight variations are related to the upstream granulating process. The objective of this intensive training is therefore to provide a deeper insight into functional relationships between granulation and tabletting in order to avoid such problems from the very beginning.
The training also conveys a deeper understanding for tableting and granulating processes, including Scale-Up, which helps in avoiding problems or solving them in practice. This also complies with the GMP principle of understanding and controlling the critical parameters of manufacturing processes. An introduction to the different GMP requirements for manufacturing solid dosage forms worldwide is therefore also subject of this course.
Granulation and tableting are considered the most commonly used manufacturing processes in the pharmaceutical industry. Of course, a direct compression process is most preferred; in practice, however, an upstream granulation is usually required to obtain a favourable particle size distribution, flowability and compactibility. Different requirements for granulates call for different procedures or technologies. Nowadays, fluid bed, high-shear or dry granulation are the most commonly used processes. An important part of this course is therefore to introduce the different granulation methods, their basic principles and Scale-Up approaches. A deeper insight into process parameters and their influence on product properties is also part of the programme.
The holistic approach to granulation and tableting therefore aims at avoiding issues from the very beginning and to overcome problems at an industrial scale through in-depth process insights. A separate block of this seminar is dedicated to the issue of Trouble Shooting. Please bring your questions concerning manufacturing problems with you or send them in beforehand.
These challenges are met by new excipients, new control algorithms for tablet presses, laminations as well as special punches and dies. Having the presses run slower should be a last resort after all other options have failed.
Further topics of this training are the tableting of highly active materials, the implementation of recent validation requirements based on the example of tablet manufacturing as well as continuous manufacturing.
This intensive course is designated for all professionals from Pharmaceutical Development, Production and QA/Regulatory Affairs, who are responsible for the development, the routine production or the Scale-Up and transfer of tableting processes.
