Particle Size Analysis in Pharmaceutics: Principles, Methods and
The particle size range for direct-compression tablets tends to be within the 100–200 μm range, mostly because of their required compaction behaviour and powder flow properties. However, smaller particle sizes of about 20–50 μm are likely to be optimal for chewable (taste-masked) and fast-disintegrating tablets, where the controlled ...

Ultrasmall-in-Nano: Why Size Matters
Multiple studies [36,37] have compared particles within the size range 1–5 nm to particles larger than 5 nm and the findings are in almost unanimous agreement. That is, larger (>5 nm) particles show low to undetectable levels in the urine as they cannot pass through the glomerular pores, and significant levels accumulating in the liver and ...
