Journal ArticleDOI
Tensile and shear methods for measuring strength of bilayer tablets
TL;DR: The shear method may be used for routine quality test of bilayer tablets during manufacturing because of its speed and convenience, provided a protocol for careful control of the placement of the tablet interface, tablet orientation, and blade is implemented.
Journal ArticleDOI
Molecular Interpretation of the Compaction Performance and Mechanical Properties of Caffeine Cocrystals: A Polymorphic Study.
Aditya B. Singaraju,Dherya Bahl,Chenguang Wang,Dale C. Swenson,Changquan Calvin Sun,Lewis L. Stevens +5 more
TL;DR: Combining the experimental and computational data indicate that the structural organization in Form 1 of CAF:NBA improves the compressibility and plasticity of the material, and from the tabletability studies, each of these contributions confer superior tableting performance to Form 1.
Journal ArticleDOI

Journal ArticleDOI
Reduction of Punch-Sticking Propensity of Celecoxib by Spherical Crystallization via Polymer Assisted Quasi-Emulsion Solvent Diffusion.
Hongbo Chen,Shubhajit Paul,Hongyun Xu,Kunlin Wang,Mahesh K. Mahanthappa,Changquan Calvin Sun +5 more
TL;DR: It is demonstrated that the punch-sticking propensity of a highly sticky API, celecoxib (CEL), can be effectively reduced by spherical crystallization enabled by a polymer-assisted quasi-emulsion solvent diffusion (QESD) process.
Journal ArticleDOI
