Influence of Film Coating Process Parameters on the Gloss of Tablets Coated with Pigmented Aqueous Film Coating Formulations
Opadry® II 1 Influence of Film Coating Process Parameters on the Gloss of Tablets Coated with Pigmented Aqueous Film Coating Formulations PURPOSE A common practice for enhancing the gloss of coated tablets is the application of a clear top-coat after applying a pigmented coating layer. In a recent study, substantial increases in tablet gloss were achieved using this multiple step approach.1 It ...
متن کاملFlow Visualization Around a Non - Circular Tube
The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...
متن کاملAqueous-based Film coating of Tablets: Study the Effect of Critical Process Parameters
The aim of the present work was to study the effect of various process parameters on an aqueous-based film coating process of tablets performed in a side-vented perforated pan-coating apparatus. Results of preliminary trials indicate that spray rate, inlet air temperature, percentage solid content, atomizing air pressure and speed of rotation affected characteristics of coating. A 3 full factor...
متن کاملStability of viscous film flow coating the interior of a vertical tube with a porous wall.
The stability of the gravity-driven flow of a viscous film coating the inside of a tube with a porous wall is studied theoretically. We used Darcy's law to describe the motion of fluids in a porous medium. The Beaver-Joseph condition is used to describe the discontinuity of velocity at the porous-fluid interface. We derived an evolution equation for the film thickness using a long-wave approxim...
متن کاملA Review on Aqueous Film Coating Technology
Until about 1950, sugar coating was the first choice as coating agent for pharmaceutical preparation and much time & efforts were spent in perfecting the sugar coating techniques. Nobody ever was concerned about the problems like material cost, toxic effect due to coating or pollution etc. because the solvent used was always water. However, sugar coating technique was time consuming, affecting ...
