During the tableting process, which operation comes last?

In the tableting process, coating is the operation that comes last. After the active pharmaceutical ingredients and excipients have been blended to ensure uniformity, they undergo granulation to improve flow and compressibility. Then, milling may occur to achieve the desired particle size before the final tableting stage. However, the last operation performed is coating, which involves applying a layer to the tablets for various purposes, such as improving stability, enhancing appearance, controlling release, or masking taste. This step occurs after the tablets have been compressed and before they are packaged for distribution. Therefore, coating is essential for the final quality and performance of the tablet dosage form.
