What is it?
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 while the stearate chain maintains the lubricity of the compound, supporting low ejection forces.
What is it used for?
- Orodispersible tablets
- Effervescent dosage forms
- Formulations containing poorly water-soluble drugs
Compared with the widely used lubricant magnesium stearate, Alubra® offers:
- Enhanced dissolution
- Compatibility with a range of APIs
- Flexibility in blending
- Improved compactability
- Similar lubrication performance
- Better tablet quality
