Description of key information

From the ten examined samples, the 10% of the sample of Betamethasone presents a particle size lower than 0.003962 mm.

Additional information

From the experimental data obtained in the laser test of the analysed lots, it can be concluded that the 10% of the sample of Betamethasone presents a particle size lower than 0.003962 mm. In particular, from the obtained values, D10 range from 3.962 to 7.032 μm; D50 range from 21.06 to 25.156 μm; D90 range from 46.321 to 57.968 μm.

These studies were conducted according to ISO 13320 -1 .
