2. INTRODUCTION
• The New Drug Application (NDA) is the
vehicle in the United States through which
drug sponsors formally propose that the FDA
approve a new pharmaceutical for sale and
marketing.
• The NDA mainly contains
– Clinical and non clinical data and analysis
– Drug chemistry information

2

3. • The FDA has established the guideline for
formatting, assembling and submitting NDA.
• NDA shares many common element with the
COMMON TECHNICAL DOCUMENT (CTD)
developed by ICH.

pure and wholesome, safe to eat, and produced under
sanitary conditions; that drugs and devices are safe and
effective for their intended uses; that cosmetics are safe
and made from appropriate ingredients; and that all
labeling and packaging is truthful, informative, and not
deceptive

reviewer to reach safety, efficacy and quality for
pharmaceutical production
