“Molecular Investigation of Pharmaceutical Formulations in Preclinical Development”
Chemical and physical stability of drug substances in pharmaceutical dosages exhibits critical attributes in preclinical development. This presentation will try to elaborate the molecular structure related risks in formulation design and how NMR is employed to tackle these analytical challenges. The contents will cover structural investigation of drug products from solid dosages of small molecule drugs and parenteral formulation of peptides. Chemical and biophysical events including phase conversion of crystalline or amorphous active pharmaceutical ingredients, aggregation of peptides, stabilizing and destabilizing interactions in multicomponent formulations will be discussed. Successful examples utilizing dynamic nuclear polarization (DNP) and proton detection under ultra-fast spinning in practical formulation characterization will be included, as efforts to advance solid-state NMR technologies in pharmaceutical sciences.
