B) Film coating: - Film coating and the sugar coating share same equipment and the process parameters. There are basically 2 methods of film coating they are I. Pan pour methods: Tablets coated by pan pour method subjected to alternate solution application, mixing and drying steps are similar to pan pour sugar coating.
Tablet Coating techniques: Concepts and recent trends . The parameter or variable inputs to a film coating process derived from differences in equipment installations include but are not limited .
Overview Of The Film Coating Process And Difference Between Solvent And Aqueous Coating Film Coating Process Pharmaceutical tablets can be film coated in a single stage process that is rapid and results in minimal weight gain of at 2 – 3% compared with sugar coating which adds 60 to 80%.
Film Coating. Minimal weight gain (2-3% as opposed to 60-80 % for sugar coating) Coat is less likely to affect disintegration; Single stage process an so generally quicker; Easy to automate (less reliance on skilled operator / easier to meet GMP requirements of SOPs, validation etc) Maintains original shape of the core & allows for embossing
tablet cores), the film coating material, and the setup of the coating process. As long as the tablet cores have sufficient hardness, low friability, and an appropriate shape, they pose no particular issue in terms of achieving good coating results. Ready-to-use film coating materials, such as those my company supplies , are carefully .
Understanding Tablet Coating Process. Coating methods. There are two principal methods of coating tablet: sugar coating and film coating. Both have advantages and disadvantages, and the following table provides a comparison between the two methods. The choice of which method is appropriate depends to an extent on how the tablets have been .
Thermodynamic film coating conditions provided in the tablet film coating process impact film coat formation and subsequent product quality. A thermodynamic film coating model was used to evaluate film coating process performance over a wide range of film coating equipment from pilot to industrial scale (2.5-400 kg).
T. O'Connor, S. Lee, in Developing Solid Oral Dosage Forms (Second Edition), 2017. 37.4.6 Coating. The film coating is typically performed for cosmetic purposes, but the film coat is also sometimes used to modify the release of API and achieve the desired tablet performance. Film coating usually involves a process where tablets are sprayed with a pigment-containing polymer solution while .
