Abstract
This study aimed to provide a new drug delivery system for hydrophobic compounds. Dexamethasone (DEX) was employed as a hydrophobic model drug, which incorporated into the network of hydroxyapatite (HA)/Cyclodextrin (β-CD) nanocomposite. Phase analysis, chemical bonding, morphology, and drug release was evaluated using XRD, FTIR, FESEM, and UV-vis spectroscopy, respectively. XRD patterns showed the formation of the crystalline structure and FTIR analysis showed the chemical bonding between organic and inorganic phases. FESEM images accompanied by EDX analysis confirmed the presence of HA nano-flakes. Release of DEX loaded β-CD/HA was measured to be around 4.6% and 18.7% in pH5.3 and pH 7.4, respectively. In conclusion, the prepared system could be a potential pH sensitive carrier for sustainable release of water-insoluble drugs.
