Importance of evaluating the consolidation of granules manufactured by high shear mixer.
TL;DR: It was concluded that evaluation of the granule consolidated state, such as the mean pore diameter, was important in order to assure the dissolution properties of drug products.

TL;DR: Using near-infrared (NIR) spectroscopy, an assay method which is not affected by such elements of tablet design as thickness, shape, embossing and scored line was developed, resulting in higher predictability under the tablet design variations using the transmittance technique with preferable linearity and accuracy.

Shuichi Yada,Masaoki Ohya,Yuko Oh-Uchi,Takeshi Hamaura,Naoki Wakiyama,Fusao Usui,Akira Kusai,Keiji Yamamoto +7 more
TL;DR: The amorphous form in equilibrium with Form B exhibited remarkable physical stability in comparison with the amorphus form obtained by continued grinding below the transition temperature, even at below the Transition temperature.

Effect of physical properties of troglitazone crystal on the molecular interaction with PVP during heating.
Susumu Hasegawa,Naho Furuyama,Shuichi Yada,Takeshi Hamaura,Akira Kusai,Etsuo Yonemochi,Katsuhide Terada +6 more
TL;DR: Results indicated that specific interaction could occur more easily during heating between milled troglitazone and PVP during preparation by a closed melting method, and Fourier transform infrared study indicated that hydrogen bonding could occur between the N-H and the C=O of PVP.
