Understanding The Dynamic Process Of Dissolution Using In-Situ Ft-Ir Spectroscopy, Vrushali M. Bhawtankar

Seton Hall University Dissertations and Theses (ETDs)

Dissolution studies provide valuable and critical drug release information (in vitro) that are important for quality control drug development. Using in-situ FT-IR spectroscopy methods has been developed for analyzing and monitoring dissolutions of pharmaceutical APIs. The accuracy of this technique was found to be ± 3% relative to HPLC and UV/Vis Spectroscopy. A dynamic analysis of the dissolution and subsequent hydrolysis of aspirin has been determined by in-situ FT-IR. This technique allows real-time analysis of the behavior of aspirin under simulated physiological conditions (pH 1.2, 4.5, 6.8) as aspirin (1205 cm-1) and salicylic acid (1388 cm ...
