Optimizing roller compaction parameters: targeting a ribbon solid fraction. The next objective is to identify the target range for ribbon solid fraction, which will relate to key roller compaction process parameters and the remaining compactability of the granule, which is important for subsequent tablet manufacture.
Although roller compaction is a widely used dry granulation process, the evaluation of critical process parameters has proven challenging because of the complex interactions among each parameter.
