Background and Purpose Niemann‐Pick disease type C (NPC) is a lysosomal storage disorder with disrupted intracellular cholesterol trafficking. A cyclic heptasaccharide, 2‐hydroxypropyl‐β‐cyclodextrin (HP‐β‐CD), solubilizer that being developed to treat NPC, but its ototoxicity pulmonary toxicity remain important issues. We have characterized 2‐hydroxypropyl‐γ‐cyclodextrin (HP‐γ‐CD), octasacchar...

Fluconazole was studied with two different hydrophilic cyclodextrins (hydroxypropyl-β-cyclodextrin (HPBCD) and sulfobutyl ether-β-cyclodextrin (SBECD)) for the formation of inclusion complexes. HPBCD and SBECD showed low cell cytotoxicity in human keratocytes as assessed by the label-free xCELLigence system for real-time monitoring. The fluconazole-HPBCD complex was incorporated into an ion-sen...

Finasteride (FIN) is a Class II candidate of the Biopharmaceutics Classification System (BCS). The lipophilic cavity of cyclodextrins (CyDs) enables it to construct a non-covalent inclusion complex with different insoluble drugs. Only β-cyclodextrin (β-CyD) and hydroxypropyl-β-CyD (HP-β-CyD) have been previously examined with FIN. This study aimed to investigate the consistence of FIN with diff...

Since several years the inclusion of organic compounds (guests) within the hydrophobic cavity (host) of cyclodextrins (CDs) has been the subject of many investigations. Interestingly, the formation of inclusion complexes could affect the properties of the guest molecules and, for example, the influence of the delivery system can be a method to improve/change the photochemical behavior of the gu...

The aim of this study was to evaluate the antidegenerative effect in osteoarthritis damage of eriocitrin alone and eriocitrin formulated as innovative "dietary flavonoid supplement." A complexation between eriocitrin and hydroxypropyl β-cyclodextrin by solubilization/freeze-drying method was performed. The complex in solution was evaluated by phase solubility studies and the optimal 1 : 2 flava...

The inclusion complexation of Epothilone A with native cyclodextrin (β- or γ-CD) and its derivative hydroxypropyl-β-cyclodextrin (HPβCD) were prepared. Their behavior, characterization, and binding ability were investigated in both solution and the solid state by means of UV-vis, NMR, XRD, DSC and SEM. The results show that the water solubility and solution stability obviously increased in the ...

This study presents improvement in solubility and dissolution rate of valsartan (VAL) using β-cyclodextrin (βCD) and hydroxypropyl-β-cyclodextrin (HP-βCD). Formation and characterization of solid inclusion complexes were investigated by DSC, FTIR, SEM, HNMR and in-vitro dissolution studies. Preparation method influenced physical properties of binary mixtures. Inclusion complexes obtained by co-...

Complexation of celecoxib with ß-cyclodextrin and hydroxypropyl-ß-cyclodextrin in the presence and absence of polyvinylpyrrolidone and the effect of polyvinylpyrrolidone on the solubilizing efficiency of cyclodextrins and on the dissolution rate of celecoxib from the cyclodextrin complexes were investigated. The phase solubility studies indicated the formation of celecoxib-ß-cyclodextrin and ce...
