external predictability for ivivc [Dissolution / BCS / IVIVC]
Hi amer,
Great to hear that.
If you also had the in-vivo data together with the new dissolution data, would the external predictability be the answer for your question? You can select external of 'predictability for ivivc model:' from GUI and then choose the dataset file (03 dataset files (*.csv) for ext. predictability) to run analysis.
However, as far as I can remember, the external predictability (or validation) is not what US-FDA recommended. Usually the internal is recommended.
❝ I have conducted IVIVC analysis using the IVIVC for R package, all good!
Great to hear that.
❝ ... how can i predict the plasma concentrations profile if i have got a new in vitro dissolution profile (not used to establish ivivc) for the same formulation done in a different dissolution media? (i.e going backwards)
