Which excipient is most often used to improve particle cohesion in granules?

• A. Filler
• B. Binder
• C. Disintegrant
• D. Lubricant

Answer: (B)

The most effective excipient for improving particle cohesion in granules is a binder. Binders play a crucial role in the granulation process by promoting adhesion among particles during the formation of granules. They are usually viscous solutions or powders that help in binding the particles together, thereby enhancing the mechanical strength and stability of the granules. When granulating a formulation, binders contribute to the formation of a cohesive mass that is essential for the uniformity and integrity of tablets or capsules. By increasing the cohesion among the particles, binders help ensure that granules have a desirable size and hardness, which are critical for the smooth processing and effective delivery of the active pharmaceutical ingredient. In contrast, fillers are primarily used to increase the bulk of the formulation without providing cohesive properties. Disintegrants are designed to aid in the disintegration of tablets in the gastrointestinal tract, facilitating the release of the drug, and lubricants reduce friction during tablet compression but do not enhance particle cohesion. Thus, binders are specifically suitable for enhancing particle cohesion in granulation processes.
