[The crystallography behavior of carbamazepine under compression pressure].
TLDR
The crystallographic behavior of the carbamazepine modifications I, II and III were studied under various conditions by means of X-ray powder diffraction, IR-spectroscopy and differential-scanning-calorimetry to find that the crystal lattice is relative stable to the applied pressure forms. Expand
[Polymorphism of drugs in powders and tablets. 6. X-ray diffractometric studies of polymorphic modifications of tolbutamide].
TLDR
The modifications and spray dried products of tolbutamide, published in a former article, are investigated furthermore by X-Ray diffraction and Transformations of modification are provable in consequence of thermal stress. Expand
[Phase transformation of carbamazepine by the milling process].
TLDR
The interconversion behavior of the carbamazepine modifications I, II and III under various grinding conditions (variation of milling aggregates, milling times and frequencies) were studied and the kinetic of phase transformations were determined. Expand
[Improvement of the solubility of problem drugs. 1. Production of iomeglamic acid fused and solidified products].
The insoluble X-ray diagnostic iomeglamic acid could be converted to a more soluble modification by melting and solidifying it in liquid nitrogen. The amorphous state is proved by X-ray diffractionExpand
