Assessment and Research on Recrystallization on Dexamethasone Polymorph by the Use of Gas Chromatography–Mass Spectrometry and Fourier Transform Infrared Spectroscopy

Abstract
The presence of more than one crystalline form of a medication is known as polymorphism. Polymorphs have the same molecular formula but varied physicochemical features, such as solubility, which impact the pharmacological effects in the body. This paper set out to investigate how processing conditions and solvent polarity affected the crystallization and physicochemical properties of Dexamethasone. Deep freezing, law temperature cooling (4C°), and room temperature were among the processing conditions used to prepare the crystals, which can have varying degrees of solvent polarity. Researchers looked for drug polymorphisms using microscopy and Fourier transform infrared spectroscopy. The results show that the physicochemical properties of crystals were affected by the solvents and processing conditions used to create them. FT-IR detected spectra that differed from one another. Varying the polarity of the solvent and the processing conditions can lead to crystals with varying characteristics.
