Fabrication of delayed release hard capsule shells from zein/methacrylic acid copolymer blends
Hard capsule shells with an inherent delayed release action are useful for oral administration of active ingredients, which are acid-labile and/or enzymatically degradable in the gastric environment, without the need of film coating. The objective of this study was to fabricate delayed release hard…

Design-of-experiment approach to quantify the effect of nano-sized silica on tableting properties of…
There are challenges to implementing high-speed direct compression tableting for poor flow, low-density cohesive powder. Thus, excipients with adequate flowability and bulk density are desired to facilitate this process. As a major novelty, the effect of nano-sized silica (Aerosil 200®) on the…

Tablet Disintegration and Dispersion under In Vivo-like Hydrodynamic Conditions
Disintegration and dispersion are functional properties of tablets relevant for the desired API release. The standard disintegration test (SDT) described in different pharmacopoeias provides only limited information on these complex processes. It is considered not to be comparable to the biorelevant…

Hot-melt extruded hydroxypropyl methylcellulose acetate succinate based amorphous solid dispersions:…
Nucleation inhibition and maintenance of drug supersaturation over a prolonged period are desirable for improving oral absorption of amorphous solid dispersions. The present study investigates the impact of binary and ternary amorphous solid dispersions on the supersaturation kinetics of nifedipine…
