Dissolution testing is an integral part of drug product (DP) development in which an appropriate method is essential to monitor the DP batch-to-batch dissolution consistency and/or ideally to predict the in vivo release of active pharmaceutical ingredient (API). However, the dissolution profile of each DP is unique, depending on the formulation and solubility of the API. As a result, developing an appropriate dissolution method for DP development purpose is not always straightforward, e.g. understanding the solubility rate in each dissolution medium, how much surfactant is appropriate, what type of surfactant to use, etc. This research proposal is intended to study/predict the dissolution profiles of various DPs from the perspective of contact angle and surface tension of dissolution media at the solid/liquid interface of common excipient blend and respective drug loading of BCS Class II and IV API. These studies will in turn help to elucidate the relationship between wettability, media surface tension and dissolution. The intern will work under direct supervision of experienced analytical chemists performing research and development analyses. Training will include basic hands-on introduction to quantitative sample preparation, dissolution with analysis by ultra-violet spectrophotometer, and surface tension and contact angle measurement using a tensiometer.


The analyst will understand the wetting properties of a surfactant with a drug surface to establish the relation between wettability and dissolution of drug product. The analyst will be responsible for preparation of reagents and materials to execute experiments. Under the guidance of an experienced chemist, the intern will measure contact angle and surface tension using a tensiometer, perform dissolution testing and analyze samples using ultra-violet spectrophotometer. The analyst will organize these results into concise research summaries and provide a final presentation documenting the outcome of the research studies.

Experie nce

Completion of at least 1-year of chemistry education in a bachelor's degree program, including laboratory courses. Completion of coursework in analytical chemistry is desired to provide a background in operating principles of the analytical tools used.
