Numerical Simulation of Film Formation in Tablet Coating

چکیده
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 repeated numerous times until a film of desired thickness is achieved. The number of repetitions needed as well as the quality of the final coating depends strongly on the quality of the partial coating. Therefore, it is of great interest to study the outcome of a single coating event in detail.

Investigating dissolution performance critical areas on coated tablets: a case study using terahertz pulsed imaging.
During the process development of coated tablets, knowledge on the formation and the location of film coating 'weak spots' is a key factor to the success of the process and the resulting product batch. It is understood that the performance of the product batch may be greatly limited, and often compromised, by weak spots on the tablet film coat. This study uses circular, biconvex tablets to inve...

متن کاملThe 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...
متن کاملA Quality by Design Approach for Coating Process Parameter Optimization
Film coating is an essential unit operation in tablet manufacturing. Most tablet dosage forms in the market are film coated. The main purpose for coating of immediate release film dosage form is to provide colour identification, to enhance the stability, taste masking. It is also noted that film coating can improve the processibility and handling during pharmaceutical manufacturing and is the m...
متن کاملEffect of Alkali and Heat Treatment on Biomimetic HA Coating on Ti6Al4V
In this study, time of calcium phosphate formation on Ti6Al4V alloy with or without alkali and heat treatments was investigated. Specimens were soaked in 0, 5, 10 M solutions of NaOH at temperatures of 60 or 80 °C for 24, 72 h. Their surfaces were characterized using scanning electron microscopy and thin film X-ray diffraction. It was found that optimum condition is 72h soaking in 5 M NaOH in 8...
