Preparation of Inclusion Complex of Piroxicam with Cyclodextrin by Using Supercritical Carbon Dioxide
Forming complexes with cyclodextrins can enhance the dissolution rate, the stability, the solubility and the bioavailability of a drug. In this work, piroxicam/β-cyclodextrin complexes were prepared at solid state by means of supercritical carbon dioxide. The influence of temperature, residence time, water content and a ternary agent, L-lysine, were studied. The complex was characterized by Dif...
متن کاملOral bioavailability and hypoglycaemic activity of tolbutamide/cyclodextrin inclusion complexes.
The purpose of the present study was to evaluate the enhancement of tolbutamide (TBM) oral bioavailability and hypoglycaemic activity through complexation with beta-cyclodextrin (beta-CD) and hydroxypropyl-beta-cyclodextrin (HP-beta-CD). TBM and its freeze-dried inclusion complexes were administered to rabbits (New zealand breed; n=6), in a dose of 20 mg/kg. TMB plasma levels were measured by H...
متن کاملEnhanced dissolution and oral bioavailability of coenzyme Q10 in dogs obtained by inclusion complexation with γ-cyclodextrin
Purpose: The solubility of coenzyme Q10 (CoQ10) in water is extremely low, resulting in a low oral bioavailability. In this study, we attempted to improve the low dissolution and bioavailability of CoQ10, by means of the complexation with natural α-, βand γ-cyclodextrins (CyDs) and 2-hydroxypropyl-β-CyD (HP-β-CyD). Methods: The complexation of CoQ10 with CyDs was studied by the solubility metho...
متن کاملBioavailability of an R-α-Lipoic Acid/γ-Cyclodextrin Complex in Healthy Volunteers
R-α-lipoic acid (R-LA) is a cofactor of mitochondrial enzymes and a very strong antioxidant. R-LA is available as a functional food ingredient but is unstable against heat or acid. Stabilized R-LA was prepared through complexation with γ-cyclodextrin (CD), yielding R-LA/CD. R-LA/CD was orally administered to six healthy volunteers and showed higher plasma levels with an area under the plasma co...
متن کاملEffect of γ-Cyclodextrin Inclusion Complex on the Absorption of R-α-Lipoic Acid in Rats
R-α-lipoic acid (RLA) is an endogenous organic acid, and works as a cofactor for mitochondrial enzymes and as a kind of antioxidant. Inclusion complexes of RLA with α-, β- or γ-cyclodextrins (CD) were prepared and orally administered as a suspension to rats. Among them, RLA/γ-CD showed the highest plasma exposure, and its area under the plasma concentration-time curve (AUC) of RLA was 2.2 times...
