Validation of Manufacturing Process
Soft capsule manufacturing process.
SCOPE OF WORK
The validation of the manufacturing process included, among other things, the following aspects:
- determination of the process-critical parameters at the stage of each operation (input formation, hull formation, capsule filling, drying)
- evaluation of the qualification status of all the equipment involved in the process
- evaluation of the manufacturing documentation – necessary specifications, technology instructions, production report template, etc. as well as staff training,
- analysis of product for consistence with the specification on different stages
A sampling plan (inspection stages, number of samples) was prepared on the basis of a risk analysis, taking into account the components listed above.
The validation was performed on 3 production batches. For each batch, statistical test results were prepared and the process capability ratios: Cp (a measure of scattering of a given feature in relation to the tolerance field) and Cpk (a measure of shift of the mean value of a given feature compared with its nominal value and tolerance limits) were determined.
The validation confirmed that the processes ran in a stable way and the finished product was consistent with the specification.
