Title:
PROCESS FOR PREPARATION OF FLUTICASONE PROPIONATE FORM 1
Document Type and Number:
Japanese Patent JP2017031161
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a novel crystallization process for preparing fluticasone propionate as crystalline form 1 polymorph having controlled particle size and being suitable for micronization.SOLUTION: The novel crystallization process comprises the step of dissolving fluticasone propionate in acetone or in a solvent comprising a mixture of acetone and 0-10% water, and then adding this solution to water or to a non-solvent comprising a mixture of water and 0-35% acetone, thereby crystallizing fluticasone propionate out of the solution as a crystalline form.SELECTED DRAWING: Figure 4
