Abstract

Loratadin (LOR) je antihistaminik niske topljivosti. Međutim, poznato je da mu se topljivost povećava kompleksiranjem s ciklodekstrinima.U ovom radu ispitana je mogućnost priprave inkluzijskog kompleksa loratadina i (2-hidroksipropil)-β-ciklodekstrina mljevenjem u mlinu bez i uz dodatak male količine organskog otapala, te u različitim stehiometrijskim omjerima loratadina i ciklodekstrina. Pripremljeni uzorci analizirani su infracrvenom spektroskopijom, razlikovnom pretražnom kalorimetrijom i difrakcijom rendgenskog zračenja na praškastom uzorku. Dobivenim produktima i čistom loratadinu određena je topljivost u vodi i biorelevantnim medijima (pH 4,5 i 6,8) UV/VIS spektroskopijom i tekućinskom kromatografijom visoke djelotvornosti.

Abstract (english)

Loratadine (LOR) is a low-solubility antihistamine. However, it is known that its solubility increases through complexation with cyclodextrins. In this study, the possibility of preparing an inclusion complex of loratadine and (2-hydroxypropyl)-β-cyclodextrin was examined by grinding in a mill with and without the addition of a small amount of organic solvent, and in various stoichiometric ratios of loratadine and cyclodextrin. The prepared samples were analysed by infrared spectroscopy, differential scanning calorimetry, and X-ray powder diffraction. The solubility of the obtained products and pure loratadine was determined in water and biorelevant media (pH 4.5 and 6.8) using UV/VIS spectroscopy and high-performance liquid chromatography.
