Compression of lactose, glucose and mannitol granules

Area of Science:

• Pharmaceutical Sciences
• Materials Science

Background:

• Tablet properties are critical for drug efficacy and patient compliance.
• Understanding the impact of manufacturing parameters on granule and tablet characteristics is essential for pharmaceutical development.

Purpose of the Study:

• To investigate the effects of granulation liquid amount, compression speed, and maximum compression force on the compressibility and compactibility of lactose, glucose, and mannitol granules.
• To evaluate the resulting tablet porosity and weight uniformity.

Main Methods:

• Granules of lactose, glucose, and mannitol were prepared.
• The influence of varying granulation liquid, compression speed, and force on granule and tablet properties was systematically studied.
• Tablet compressibility, compactibility, porosity, and weight uniformity were measured.

Main Results:

• Lactose and mannitol granules exhibited superior compressibility compared to glucose.
• Mannitol granules yielded the hardest tablets, while lactose and glucose produced weaker tablets.
• Tablet strength was influenced by granulation liquid amount, affecting granule porosity and binder content.
• Compression speed had minimal impact, except for mannitol tablet breaking force, which was highest at the lowest speed.
• Lactose granules resulted in the best tablet weight uniformity.

Conclusions:

• Granule properties and manufacturing parameters significantly influence tablet characteristics.
• Lactose and mannitol are promising materials for tablet formulation due to their compressibility and strength.
• Optimizing granulation liquid and compression force is key for achieving desired tablet quality, particularly weight uniformity.
