Abstract

This article introduces a practical approach to determining the best estimate for probability of passing uniformity of dosage units (content uniformity) using probability vs. lot coverage charts and tables constructed using simulated probability and lot coverage (LC1) data. The best estimation concept is to demonstrate that the probability estimates, especially for those approaching 100%, are slightly different (deviated) from the exact calculated values by not more than (NMT) the statistically acceptable deviation limits.
