A process for preparing crystalline drug particles by means of precipitation |
| abstract |
A process for preparing crystalline particles of a drug substance is disclosed, said process comprising recirculating an anti-solvent through a mixing zone, dissolving the drug substance in a solvent to form a solution, adding the solution to the mixing zone to form a article slurry in the anti-solvent, and recirculating at least a portion of the particle slurry back through the mixing zone. Particles produced from the process are also disclosed. The present invention has the ability to be operated in a continuous fashion, resulting in a more efficient process and a more uniform product. The present invention has the additional advantage of having the ability to operate at a relatively low solvent ratio, thereby increasing the drug to excipient ratio. |
