Provided are links to two recent articles, written by Dr. L.T. Grady who was Vice President and Director of USP Division of Standard Developments (1980-2000), from the website of Dr. T. Layloff, who later himself was Vice President and Director of USP Division of Standard Development.
The titles of the articles are “Letter on the Adequacy of Dissolution Testing” and “Perspective on the History of Dissolution Testing”.
The contents of the articles are quite revealing, indicating that the high variability in dissolution results and their poor link to the product quality were well known within USP.
