Abstract

This review focuses on different film coating approaches used for Ferrous Ascorbate and Folic Acid tablets, which play a vital role in enhancing tablet appearance, taste, stability, and drug release. Conventional sugar coating improves palatability but adds weight and extends processing time. In contrast, modern film coating techniques employing polymers such as hydroxypropyl methylcellulose (HPMC), ethyl cellulose, and polyvinyl alcohol (PVA) provide better protection against moisture and enable controlled release. Enteric coatings safeguard the active ingredients from gastric acid, while ready-to-use coating systems like Opadry simplify the manufacturing process and ensure uniformity. The review also highlights the increasing interest in natural polymers like chitosan and plant-based materials for eco-friendly and safe applications. Various process parameters—such as temperature, spray rate, and drying conditions—are discussed, along with evaluation parameters like dissolution, disintegration, friability, and stability. Overall, modern coating technologies have improved the quality, performance, and patient acceptability of Ferrous Ascorbate and Folic Acid tablets. Further studies on biodegradable coating agents and process optimization can lead to more efficient and sustainable pharmaceutical products.
