The ‘full tolerance coverage method’ is introduced as a coverage estimation approach for assessing the uniformity of dosage units from large sample sizes, ensuring that no dosage unit exceeds the specification range.
Total Analytical Error in Validation of Analytical Procedures of Pharmaceuticals
May 2nd 2023This paper demonstrates how assay data sets of a formulated liquid product, drug substance, and an impurity, obtained from combined accuracy-precision studies, are evaluated to calculate statistical intervals (prediction and tolerance intervals) and to graphically display the total analytical error (TAE) to account for the systematic and random errors.
