Comparative studies of different modifications of calcium valproate

, : Comparative studies of different modifications of calcium valproate. International Journal Of Pharmaceutics (amsterdam). 115(2): 245-248

The crystalline state of calcium valproate (CaV) in different modifications, prepared by us, was investigated using infrared (IR) spectroscopy, X-ray powder diffraction patterns, simultaneous thermal analysis (STA combined thermogravimetry TG and differential thermal analysis DTA), and scanning electron microscopy (SEM). The influence of the simple recrystallized solvent on the crystal state of the drug is evident.
