Extended-release (ER) tablets are designed to provide controlled drug release over a prolonged period, ensuring consistent therapeutic levels. The selection of an appropriate polymer matrix is critical to achieving desired release kinetics, bioavailability, and stability. Poor polymer selection can lead to dose dumping, inconsistent release profiles, and stability issues.

Tablet capping and lamination are serious defects in pharmaceutical manufacturing that compromise tablet integrity, stability, and patient safety. Capping occurs when the upper or lower tablet layer separates, while lamination involves the splitting of tablets into multiple layers. These defects are caused by issues in formulation, compression force, and granulation process.

The selection of an appropriate binder is crucial in tablet formulation as it directly impacts tablet strength, disintegration, and overall product stability. Poor binder choice can lead to tablet friability, capping, lamination, and variations in drug release. Balancing tablet hardness and rapid disintegration requires an optimized binder strategy tailored to formulation needs.

Tablet lubrication is essential for reducing friction, preventing sticking, and ensuring smooth tablet ejection from the die cavity. However, excessive lubrication can negatively impact tablet hardness, disintegration, and drug dissolution. Poor lubrication may lead to tablet capping, lamination, and weight variation, affecting batch quality and regulatory compliance.
