| 摘要 |
The invention relates to (a) phenothiazine or a phenothiazine analog or derivative (phenothiazine material) in the form of prills of a generally spherical shape containing very low levels of fines and also (b) a method of forming a phenothiazine material in prill form having a generally spherical shape. The prilled phenothiazine material exhibits improved handling, flowability and dissolation times, while minimizing the generation of fines, and the problems of irritation and sensitization through exposure to such fines.
