Inclusion Complexes of Terfenadine-Cyclodextrins

Drug Development and Industrial Pharmacy, 1995
Terfenadine, a poorly soluble, H1-antihistamine was solubilised using B-cyclodextrin and its derivatives. A molar ratio of 1:1 of the drug and cyclodextrin was prepared by the kneading method. The inclusion complex was characterised and evaluated by Differential Scanning Calorimetry & X-ray Diffractometry.

Zeolite inclusion complexes

Journal of Inclusion Phenomena, 1983
Zeolites provide the largest and most useful family of porous host crystals, stable in the presence or absence of guest molecules. An account is given of their structural characteristics in terms of intracrystalline channels and cavities of molecular dimensions; their total intracrystalline pore volumes; and the intracrystalline distribution patterns ...

Menadione-?-cyclodextrin inclusion complex

Journal of Inclusion Phenomena, 1985
A stable, nonsublimable γ-cyclodextrin inclusion complex of menadione (Vitamin K3) of 11.7% menadione content (molar ratio 1:1) was prepared in solution, in suspension, and by ‘kneading’. The physicalchemical properties of the complex formed were studied by X-ray diffraction, by thermal analysis (DTG, TG, DSC, TEA), and by chiroptical studies.

Inclusion Complex Formation

1978
One of the most important characteristics of cyclodextrins is the formation of inclusion complexes with various compounds (guests), in which guest compounds are included in the cavity of cyclodextrins (host) [20, 65–67]. Guest compounds range from polar reagents such as acids, amines, small ions such as ClO 4 - , SCN-, and halogen anions [68] to highly

Fendiline-?-Cyclodextrin inclusion complex

Journal of Inclusion Phenomena, 1985
Fendiline (N-[1-phenylethyl]-3,3-diphenylpropylamine hydrochloride, trade name: Sensit) is a β-receptor blocker and a Ca antagonist. It is a viscous oil and even its crystalline hydrochloride is a very hydrophobic and sparingly soluble compound in water.β-Cyclodextrin complexes fendiline base in a molar ratio of 2∶1.

Cyclodextrin Inclusion Complexes

1988
Inclusion complexes are molecular compounds having the characteristic structure of an adduct, in which one compound (host molecule) spatially encloses another. The enclosed compound (guest molecule) is situated in the cavity of the host without significantly affecting the host framework structure. Apart from a slight deformation, it is a characteristic

Bioactive Permethrin/β-Cyclodextrin Inclusion Complex

The Journal of Physical Chemistry B, 2006
Permethrin is popularly used in a variety of therapeutic areas. However, the poor water solubility of permethrin seriously limits its wider clinical applications. The present study demonstrates that solubility of permethrin in aqueous solution can considerably increase in the presence of beta-cyclodextrin (beta-CD).

Cyclodextrin inclusion complexation

1989
The type of bonded phase for HPLC based on the class of oligosaccharides known as cyclodextrins employs inclusion complexing to achieve chiral selectivity. How inclusion complexing accomplishes this is best understood by examining the physical structure of cyclodextrins.
