An overview on dry powder coating in advancement to electrostatic dry powder coating used in pharmaceutical industry

The protection of pharmaceutical drugs by coating with suitable coating powder polymers plays a crucial role in the pharmaceutical industry. The dry coating is preferred due to its advantages, like reducing the overall coating amount and curing time. This has been an alternative method to liquid base coating techniques. Recently, pharmaceutical industries have been attracted to advances in the dry coating, i.e. Electrostatic dry powder coating. The peer-review summarized the adoption of the dry coating process, which involves the dry powder coating, hot-melt extrusion process, and electrostatic dry powder coating of tablets/pellets and their influencing parameters to achieve a fruitful product. To summarize this review, all the data extracted from previous journals, and parameters that influence the coating efficiency, drug release rate, ageing phenomenon, etc., have been highlighted.
