COHERENT ANTI STOKES RAMAN SCATTERING MICROSCOPY TO MONITOR DRUG DISSOLUTION IN

Coherent anti-Stokes Raman scattering (CARS) microscopy is used to visualize the release of a model drug (theophylline) from a lipid (tripalmitin) based tablet during dissolution. The effects of transformation and dissolution of the drug are imaged in real time. This study reveals that the manufactu
