A wide variety of pharmaceutical products, including pellets, granules, capsules, powders, and crystals are often coated. The procedure of coating tablets is a complex process that results in the forming of a thin layer around the tablet. This layer is in the range of 20 to 200 μm in thickness, or around 1 to 9% of the initial weight of the tablet.

A Comparative Study on the Coating Performance of Wurster, Bottom and Top Spray Fluidized Bed…
Abstract
This study compared the coating applicability and performance of Wurster, bottom and top spray coaters. Two key indices – coating variability and efficiency – were estimated by the ray tracing model coupled with CFD-DEM simulations. The effects of the fluidizing gas velocity and the spray…

Application of Biomaterials in the Development of Enteric-Coated Luminar Capsule Microneedles for…
Abstract
In commercial applications, sofosbuvir (SOF) for hepatitis C is only available in tablet dosage form, resulting in minimal SOF accumulation in the liver (26.94%) due to its low intestinal permeability and high molecular weight (529.5 Da). Therefore, in this study, luminar capsule…

Solid lipid–threshold guided chitosan coating of NLCs for improved gastrointestinal stability and…
Abstract
Chitosan-coated nanostructured lipid carriers (CS-NLCs) were engineered to overcome the gastrointestinal instability and limited absorption of glycerol distearate (GDS)/medium-chain triglyceride (MCT)-based NLCs. Using a dropwise coating method, we systematically evaluated the impact of…
