    • PURPOSE: An organic salt of amlodipine is provided which has improved physicochemical properties. It is particularly excellent in photostability and solubility. Therefore, it is easily absorbed into the body of a patient and stored for a long time. CONSTITUTION: An pyroglutamic acid salt of amlodipine is represented by the formula(2), wherein the pyroglutamic acid is (S)-(-)-pyroglutamic acid or (R)-(+)-pyroglutamic acid; the pyroglutamic acid salt of amlodipine has crystal form and photostability; the amlodipine is (2-£(2-aminoethoxy)methyl|- 4-(2-chlorophenyl)- 1,4-dihydro-6-methyl- 3,5-pyridinedicarboxylic acid 3-ethyl-5-methyl ester) represented by the formula(1). A method for preparing the organic salt of amlodipine of the formula(2) comprises reacting the amlodipine with pyroglutamic acid in a solvent selected from ethyl acetate, methanol, ethanol, isopropanol, acetonitrile, hexane and isopropyl ether.
