Preparation and Evaluation of Rapidly Disintegrating Fast Release Tablet of Diazepam-Hydroxypropyl-β-Cyclodextrin Inclusion Complex
This study was undertaken to develop tablets of diazepam-hydroxypropyl-β-cyclodextrin inclusion complex that disintegrate within 3 minutes and release 85% of drug within 30 minutes to provide rapid action of the drug through oro-mucosal route. Formation of inclusion complex was verified using X-ray diffraction and differential scanning calorimetric studies. Enhanced of aqueous solubility, as ev...
متن کاملDissolution Rate Enhancement, Design and Development of Buccal Drug Delivery of Darifenacin Hydroxypropyl β-Cyclodextrin Inclusion Complexes
Darifenacin is a urinary antispasmodic. The oral absorption of darifenacin is poor due to its low solubility and poor bioavailability (15-19%). Darifenacin was complexed with hydroxylropyl beta-cyclodextrin (Hpβ-CD). The best results were obtained with the coevaporation that interacts in a 1 : 1 drug : cyclodextrin molar ratio. The solid inclusion complexes were found to be amorphous in the cha...
متن کاملEffect of Cyclodextrin Complexation on the Aqueous Solubility of Diazepam and Nitrazepam: Phase-Solubility Analysis, Thermodynamic Properties
The solubility enhancement of diazepam and nitrazepam in water was analyzed depending on temperature and amount of α-cyclodextrin (α-CD), β-cyclodextrin (β-CD) and 2-hydroxypropyl-β-cyclodextrin (2-HP-β-CD). The interactions of drug-cyclodextrin in solution were investigated by the phase-solubility analysis. Diazepam (nitrazepam) content in aqueous complexation medium was analyzed UV spectropho...
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 کاملStudies on the Preparation, Characterization, and Solubility of 2-HP-β-Cyclodextrin-Meclizine HCl Inclusion Complexes
Meclizine HCl is a poorly water-soluble drug having a very slow-onset of action. The effect of 2-hydroxypropyl-β-cyclodextrins and β-cyclodextrins on its aqueous solubility and dissolution rate was investigated. The phase solubility profile indicated that the solubility of Meclizine HCl was significantly increased in the presence of both 2-hydroxypropyl-β-cyclodextrin and β- cyclodextrin; an ex...
