Alubra®

 
Alubra offers improved API dissolution
Lubricants are a vital part of the tableting manufacture process. Formulators have typically selected magnesium stearate to meet these needs as a familiar, well-established lubricant. Given today’s challenges in formulating tablets, it is important to ensure that the lubricant choice does not have a negative impact on disintegration and dissolution.Scientific evidence demonstrates that magnesium stearate can negatively impact disintegration and dissolution. Formulators need to consider these variables before selecting the appropriate lubricant for their formulation.

Alubra PG 100 is a fine, white to off-white powder used as a hydrophilic lubricant in capsule and tablet formulations. The fumarate moiety of Alubra increases its melting temperature, which allows for greater functionality at high press speeds.

High-performance lubricant for improved tableting performance
Alubra® sodium stearyl fumarate is a hydrophilic tablet binder for superior tablet performance. The fumarate increases the excipient’s melting temperature, enabling greater functionality at high press speeds. Meanwhile the stearate chain maintains the lubricity of the compound, supporting lower ejection forces and better tablet quality. In addition, the product is less susceptible to over-blending, facilitating more flexible process conditions and reduced waste as a result of batch failures.
