FDA Office and Location: A research opportunity is available within the Food and Drug Administration (FDA) in The Center for Drug Evaluation and Research (CDER), located at St. Louis, Missouri.

The Center for Drug Evaluation and Research (CDER) performs an essential public health task by making sure that safe and effective drugs are available to improve the health of people in the United States. As part of the U.S. Food and Drug Administration (FDA), CDER regulates over-the-counter and prescription drugs, including biological therapeutics and generic drugs. This effort covers more than just medicines.

Research Project: This project is located in the Office of Pharmaceutical Quality Research (OPQR), Office of Pharmaceutical Quality (OPQ). The project is to develop liquid chromatography-mass spectrometry (LC-MS) methods for the analysis of nitrosamine impurities in drug products and apply the developed and validated methods to screen for these impurities in various drug products.

Learning Objectives: Under the guidance of the mentor, the participant will gain knowledge, expertise and experience in pharmaceutical analysis, specifically in the following areas:

• Development and validation of analytical procedures to assess the qualities of pharmaceutical product.
• Application of advanced analytical techniques mainly LC-MS in pharmaceutical analysis.
• Regulations pertaining to nitrosamine and other pharmaceutical impurities,
• Regulations of Over-The-Counter (OTC) drug products.
  
  

Mentor: The mentors for this opportunity are Jingyue (Jan) Yang ([e-mail]) and Tim Marzan ([e-mail]). If you have questions about the nature of the research, please contact the mentors.
