Study Notes

Advantages of Powders in Pharmaceuticals

Powders with particle sizes below a few micrometers can be produced quickly, enhancing manufacturing efficiency.
Wet granulation process involves sieving the wet mass, which promotes rapid and uniform drying of the material.

Key Properties Affecting Powder Performance

Flowability is crucial; it is influenced by particle size and its distribution.
Free-flowing powders and granules optimize performance in high-speed filling equipment and tablet presses, ensuring product uniformity.

Importance of Particle Size in Mixing

Mixing or blending solid pharmaceutical ingredients is more effective when they are of similar sizes, leading to a more uniform final product.
Uniform size distribution among ingredients reduces inconsistencies during the mixing process, enhancing product quality.
