Solubility Enhancement of Domperidone Fast Disintegrating Tablet Using Hydroxypropyl-β-Cyclodextrin by Inclusion Complexation Technique
Domperidone Maleate (DOM), an antiemetic drug, has been used in treatment of adults and children. It has low aqueous solubility and hence low bioavailability. In present study, an attempt has been made to enhance the solubility of DOM by inclusion complexation with Hydroxypropyl-βCyclodextrin (HP-β-CD) using kneading technique and formulation of fast disintegrating tablets by using Sodium Starc...
متن کاملEncapsulation Mechanism of Oxyresveratrol by β-Cyclodextrin and Hydroxypropyl-β-Cyclodextrin and Computational Analysis.
In this study, the encapsulation mechanism of oxyresveratrol and β-cyclodextrin (β-CD) and hydroxypropyl-β-cyclodextrin (HP-β-CD) was studied. As this research shows, oxyresveratrol and two cyclodextrins (CDs) were able to form inclusion complexes in a 1:1 stoichiometry. However, the interaction with HP-β-CD was more efficient, showing up as higher encapsulation constant (KF) (35,864.72 ± 3415....
متن کاملAssisted attenuation of a soil contaminated by diuron using hydroxypropyl-β-cyclodextrin and organic amendments.
Diuron desorption and mineralisation were studied on an amended and artificially contaminated soil. The amendments used comprised two different composted organic residues i.e., sewage sludge (SS) mixed with pruning wastes, and urban solid residues (USR), and two different solutions (with inorganic salts as the micronutrients and hydroxypropyl-β-cyclodextrin (HPBCD)). After applying micronutrien...
متن کاملSolubility of Cyproterone Derivatives in the Presence of Hydroxypropyl-β-Cyclodextrin: Experimental and Molecular Modeling Studies
This study presents the influence of hydroxypropyl-β-cyclodextrin (HPBCD) on the aqueous solubility of acyl esters of cyproterone. First, a number of esters of cyproterone were synthesized. Then the phase solubility analysis of the compounds in the presence of HPBCD was investigated in phosphate buffer solution at a pH of 7.4. To gain a better understanding of the complexation mechanism, ...
متن کاملThe hydroxypropyl–β-cyclodextrin complexation of toltrazuril for enhancing bioavailability
Introduction Toltrazuril (Tol) is used to prevent and combat coccidiosis. However, its low aqueous solubility and poor oral bioavailability limit clinical application. Methods To overcome the shortcomings, toltrazuril-hydroxypropyl-β-cyclodextrin inclusion complex (Tol-HP-β-CD) was prepared and characterized. The comparative plasma disposition kinetics of Tol was analyzed after a single orall...
