Predictive Approach to Understand and Eliminate Tablet Breakage During Film Coating

نویسندگان

چکیده

Pharmaceutical tablets can be susceptible to damage such as edge chipping or erosion of the core during tablet coating process. The intersection certain process parameters, equipment design, and properties may induce more significant complete fracture. In this work, a hybrid predictive approach was developed using discrete element method (DEM) modeling lab-based impact experiments identify conditions that lead breakage events. extended examine potential modifications in silico mitigate likelihood future batches. is shown enhance understanding, optimal within development constraints, de-risk manufacture

Numerical Simulation of Film Formation in Tablet Coating

The application of a coating layer on a tablet is a commonly used technique to selectively control tablet characteristics. Among the most important functions of the coating is the regulation of the release of active ingredient. In the course of a typical coating process, the tablet passes a spray zone multiple times. Each time, a partial coating layer is applied. For each tablet, this is repeat...

Applications of terahertz pulsed imaging to sustained-release tablet film coating quality assessment and dissolution performance.

The potential of terahertz pulsed imaging (TPI) to predict the dissolution performance in sustained-release tablets was investigated in this study. Batches of coated tablets with similar weight gain during the coating process at the lab and pilot scales were subjected to non-destructive imaging by TPI and subsequently analysed by dissolution testing. The results from the dissolution tests revea...

Memetic Algorithm Approach to Thin-Film Optical Coating Design

The problem of optimizing a series of thin-film layers in order to achieve a desired reflectivity of light over a range of frequencies is studied. The approach studied here is to employ an evolutionary algorithm combined with random local searches to obtain the best fit. This Memetic Algorithm is found to result in faster convergence than in the case when no local searches are employed.

Terahertz pulsed imaging as an analytical tool for sustained-release tablet film coating.

The ability of terahertz pulsed imaging (TPI) to be employed as an analytical tool for monitoring a film coating unit operation and to assess the success of a subsequent process scale-up was explored in this study. As part of a process scale-up development, a total of 190 sustained-release tablets were sampled at 10% increments of the amount of polymer applied, from a lab-scale and a pilot-scal...

The influence of additives on the spreading coefficient and adhesion of a film coating formulation to a model tablet surface.

The surface energies of film coating formulations based on hydroxypropyl methylcellulose and containing microcrystalline cellulose, lactose and Tween 20, respectively, have been assessed. The approach taken allowed the components of the surface energy, in terms of the Lifshitz-van der Waals and the acid-base contributions, to be determined. Spreading coefficients of these coating formulations w...
