Solid State Characterization of Domperidone: Hydroxypropyl-β-Cyclodextrin Inclusion Complex
The purpose of the present study was to prepare inclusion complex of domperidone with hydroxylpropyl-β-cyclodextrin in order improved the solubility and hence to increase dissolution of domperidone. An effect of concentration of hydroxylpropyl-β-cyclodextrin on the aqueous solubility of domperidone was determined by phase-solubility method. The aqueous solubility of domperidone increased as a f...
متن کاملMolecular modelling and 1H-NMR: ultimate tools for the investigation of tolbutamide: beta-cyclodextrin and tolbutamide: hydroxypropyl-beta-cyclodextrin complexes.
A structural study of the inclusion compound of tolbutamide (TBM) with beta-cyclodextrin (beta-CD) and hydroxypropyl-beta-cyclodextrin (HP-beta-CD) was attempted by means of 1H-nuclear magnetic resonance (1H-NMR) experiments and computer molecular modelling. To establish the stoichiometry and stability constant of the beta-CD:TBM complex, the continuous variation method was used. The presence o...
متن کاملHost-Guest Interaction between Herbicide Oxadiargyl and Hydroxypropyl-β-Cyclodextrin
In the face of a growing human population and increased urbanization, the demand for pesticides will simply rise. Farmers must escalate yields on increasingly fewer farm acres. However, the risks of pesticides, whether real or perceived, may force changes in the way these chemicals are used. Scientists are working toward pest control plans that are environmentally sound, effective, and profitab...
متن کاملDevelopment and Characterization of Paracetamol Complexes with Hydroxypropyl-?-Cyclodextrin
Paracetamol is a sparingly soluble bitter tasting drug. It is widely used as an analgesic and antipyretic. Complexation of drug with different cyclodextrins (?, ? and HP-?-CD) was attempted to improve solubility of Paracetamol. During the drug excipient interaction studies, ?, ? cyclodextrins elicited analytical interference and showed considerable absorbance at ?max (243.5 nm) of Paracetamol w...
