Niemann-Pick type C (NPC) disease, characterized by intracellular accumulation of unesterified cholesterol and other lipids owing to defects in two proteins NPC1 and NPC2, causes neurodegeneration and other fatal neurovisceral symptoms. Currently, treatment of NPC involves the use of 2-hydroxypropyl-β-cyclodextrin (HP-β-CD). HP-β-CD is effective in the treatment of hepatosplenomegaly in NPC dis...
The aim of the present work was to improve the solubility and dissolution rate of simvastatin (SIM), a drug used for the treatment of hyperlipidemia. Two systems were used: solid dispersions with PEG 4000 and PEG 6000 prepared using the fusion method in various ratio of 1:1, 1:3, and 1:5 and inclusion complexes with HP-β-cyclodextrin obtained by kneading method in a ratio of 1:1 with drug SIM. ...
Complexation with cyclodextrins (CDs) is a technique that has been extensively used to increase the aqueous solubility of oils and improve their stability. In addition, this technique has been used to convert oils into solid materials. This work aims to develop inclusion complexes of Copaifera multijuga oleoresin (CMO), which presents anti-inflammatory activity, with β-cyclodextrin (β-CD) and h...
The aim of the present work was to develop novel hydrogels for delivering sertaconazole based on cyclodextrins and various biocompatible polysaccharides. Sertaconazole is an antifungal agent very effective for treatment of Candida albicans infections. However its poor aqueous solubility is still a challenging issue for developing suitable formulations. Complexation with cyclodextrins is a very ...
The encapsulation of clove essential oil (CEO) in hydroxypropyl-?-cyclodextrin (HP-?-CD) and the subsequent incorporation inclusion complex an elastic chitosan film order to achieve a controlled release profile volatile CEO are herein presented. Freshly distilled was found contain eugenol concentrations higher than 70%. kneading method implemented for preparation CEO-HP-?-CD complex, resulting ...
Icariin is a bioactive herbal ingredient isolated from Herba epimedii, which has been widely used for the treatment of osteoporosis and male sexual dysfunction in traditional Chinese medicine. The major objective of this work is to investigate the different enhancing effects of β-cyclodextrin (β-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD) on the intestinal absorption of icariin, and to ident...
Microdialysis sampling of lipophilic molecules in human tissues is challenging because protein binding and adhesion to the membrane limit recovery. Hydroxypropyl-ß-cyclodextrin (HP-ß-CD) forms complexes with hydrophobic molecules thereby improving microdialysis recovery of lipophilic molecules in vitro and in rodents. We tested the approach in human subjects. First, we determined HP-ß-CD influe...
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...
inabilities to attain adequate aqueous solubility and stability have made the preparation of a clinically suitable formulation of taxol difficult. addition of nicotinamide (nd), 2-hydroxypropyl- b-cyclodextrin (hpßcd), polyethylene glycol, (peg), bile salts (bs, 50:50 sodium cholate: deoxycholate), and cremophor el can improve the solubility of taxol. studies were undertaken to compare the stab...
To improve the stability and oral bioavailability of Z-ligustilide (LIG), the inclusion complex of LIG with hydroxypropyl- β-cyclodextrin (HP-β-CD) was prepared by the kneading method and characterized by UV-Vis spectroscopy, differential thermal analysis (DTA) and Fourier transform infrared (FTIR) spectroscopy. LIG is capable of forming an inclusion complex with HP-b-CD and the stoichiometry o...
