Application of F Charts in Continued Process Verification of OSD Forms

This article introduces a control chart technique using F statistic for continued process verification of oral solid dosage forms.

In continued process verification (CPV), there must be some kind of evaluation such that the validity of the two test data within the same CPV batch is demonstrated. One such evaluation tool is control charting using F data (i.e., F chart) to demonstrate that the consistency between dissolution and CU data is under statistical control.
