Lubricant excipients are substances that are added to tablet formulations to aid in the tableting process and to improve the flow of powders during the manufacturing of tablets. These excipients reduce friction and prevent the sticking of the tablet material to the surface of the die and punches, allowing for smoother tablet production and reducing the wear and tear on the tableting equipment.

Comparison of Different Liquid and Semisolid Vehicles Selected for Oral Administration of Pellets…
The acceptability and palatability of a dosage form are extremely important to improve patient compliance. Mixing oral solid dosage forms with food carriers is often necessary to ease swallowing and provide the taste-masking effect. The present research investigated how a liquid or semisolid carrier…

Characterization and modeling of the viscoelasticity of pharmaceutical tablets
Evolution of the compaction properties of powders with the compaction speed (strain rate sensitivity, SRS) is a common phenomenon during the manufacturing of pharmaceutical tablets. Nevertheless, several different phenomena can be responsible of the SRS like friction, viscoelasticity,…
