Controlling Fines During Tablet Compression

Posted on By Admin

Tablet compression is a vital process in pharmaceutical manufacturing, where powder blends are compacted into tablets. During this process, fine particles, or fines, are often produced, which can adversely affect tablet quality. Fines are smaller particles that are generated when larger particles break down under compression forces, leading to issues such as poor tablet consistency, increased friability, and compromised dissolution profiles. Controlling the formation of fines is essential for maintaining the integrity and performance of the final tablet product.
