dc.description.abstract | This study investigates the use of Broadband Acoustic Resonance Dissolution Spectroscopy (BARDS) as a detection method for the formation of cocrystals. BARDS is a novel approach that uses reproducible changes in the compressibility of a solvent as a sample dissolves to characterize and differentiate between materials and in this case cocrystallization. Two cocrystal systems with a 1:1 stoichiometry were examined, which used benzoic acid as a coformer with isonicotinamide and with theophylline. Cocrystals were prepared using dry and wet milling for periods from 1 to 40 min, and samples were analyzed using infrared spectroscopy, powder X-ray diffraction, and BARDS. Comparison of the BARDS data with the IR and PXRD data cross-validated the BARDS results. This study shows that BARDS can be used to rapidly assess the formation of these cocrystals at-line when milling or as a relatively low cost tool in preformulation product development. The data can also be used to gauge the unique entrained gas and gas volume generation of the cocrystal samples during dissolution and their dissolution kinetics. | en |
