Process for preparing ondansetron hydrochloride dihydrate having a defined particle size |
| abstract |
The invention provides a process for preparing ondansetron hydrochloride dihydrate particles in which at least about 70% of the particles have a particle size of less than 250 ~m, comprising the steps of: (a) preparing a solution comprising ondansetron hydrochloride and water; and (b) adding the solution into a precipitation medium which comprises a water-miscible nonsolvent for ondansetron hydrochloride, while maintaining the resulting mixture at a temperature of about 40~C or less. |
