摘要:
Disclosed are crystalline S-(−)-amlodipine adipic acid salt anhydrous and a preparation method thereof. The crystalline S-(−)-amlodipine adipic acid salt anhydrous exhibits excellent physical and chemical properties including non-hygroscopicity, solubility, thermal stability, and photostability, and is superior in formulation processability and long-term storage safety.
