摘要:
Provided is a process for preparing crystalline imatinib mesylate in substantially pure α-form, which preferably includes crystallizing imatinib mesylate from an organic solvent containing imatinib and methanesulfonic acid, and seed crystals of imatinib mesylate α-form, wherein the seed crystals are added before imatinib mesylate begins to precipitate from the mixture. Also provided are stable, free-flowing imatinib mesylate crystals in substantially pure α-form, and a pharmaceutical composition containing the stable, free-flowing imatinib mesylate crystals.
