About the PDA Letter

The PDA Letter is PDA's magazine for members covering the science, technology and regulation behind the manufacturing of sterile injectables. New articles are uploaded to the website weekly and the print edition publishes ten times per year, with issues in January, February, March, April, May, June, September and October, as well as two larger issues for July/August and November/December.

The PDA Letter is divided into three main sections: People, Science and Regulation and a features section. Articles are supplied by PDA members, industry and regulatory experts and occasionally by PDA staff. The PDA Letter Editorial Committee (PLEC) provides editorial oversight for all feature articles.
