Studying the dissolution of immediate release film coating using terahertz pulsed imaging

Runqiao Dong et al.

Summary: Coated tablets introduce complexity to the dissolution process, even with readily soluble immediate release coating layers. The current study uses terahertz pulsed imaging to visualise the hydration process of microcrystalline cellulose (MCC) tablet cores that were film coated with an immediate release coating formulation upon exposure to the dissolution medium. The penetration rate through the coating layer and the tablet core both strongly depended on coating thickness and core porosity.

Modelling the Evolution of Pore Structure during the Disintegration of Pharmaceutical Tablets

Mithushan Soundaranathan et al.

Summary: The study investigates the changes in the pore structure during pharmaceutical tablet disintegration. Experimental and modeling results demonstrate that the highest concentration of croscarmellose sodium (CCS) leads to the lowest swelling behavior due to pore closure. This study provides new insights into the impact of porosity and formulations on tablet performance.

Visualising liquid transport through coated pharmaceutical tablets using Terahertz pulsed imaging

Runqiao Dong et al.

Summary: The dissolution of coated pharmaceutical tablets is a complex process that depends on the structure of the coating and its interaction with the tablet core. This study used terahertz pulsed imaging to investigate the penetration of the dissolution medium into coated tablets. The analysis revealed a discontinuity in density at the interface between the coating and core, which affected the liquid transport and dissolution performance. The study provides insights into the role of coating in tablet dissolution.

Terahertz pulsed imaging as a new method for investigating the liquid transport kinetics of α-alumina powder compacts

Mohammed Al-Sharabi et al.

Summary: This study investigated the liquid transport kinetics of solid catalysts using Terahertz pulsed imaging (TPI) coupled with a flow cell, revealing the impact of porosity and wettability on liquid transport rates. The results demonstrate the potential of TPI for studying and optimizing the design and performance of such materials.

Simulation of densification behavior of nano-powder in final sintering stage: Effect of pore-size distribution

Byung-Nam Kim et al.

Summary: This study modeled and simulated the densification behavior of nano-sized powder in the final sintering stage, showing that the densification rate for size-distributed pores is lower than for single-sized ones. By choosing appropriate pore-size distributions, the experimental relationship between densification rate and porosity can be reproduced effectively. Additionally, the simulation revealed that the sintering stress with densification may increase or decrease depending on the pore size distribution, but is significantly lower than for single-sized pores.

Lucas-Washburn Equation-Based Modeling of Capillary-Driven Flow in Porous Systems

Jianchao Cai et al.

Summary: Fluid flow driven by capillary pressure in porous systems is a common phenomenon in nature and industry, with the classical LW equation often leading to inaccurate predictions due to assumptions that are not true for many natural situations. Recent studies have focused on modifying and extending the LW equation to improve understanding of imbibition dynamics in various porous systems. Progress in computational techniques has also helped advance research in this area.

Insights into the Control of Drug Release from Complex Immediate Release Formulations

Runqiao Dong et al.

Summary: The study utilized terahertz pulsed imaging to measure the water transport process into tablets, finding that tablet porosity is a key factor influencing liquid penetration and dissolution. NaCl significantly influences liquid penetration due to osmotic driving force and gelling suppression, but there is minimal difference when NaCl loading increases from 5% to 10%. The level of spray dried intermediate was observed to further limit the release of API in dissolution.
