The bioavailability of cinnarizine (CN) upon oral administration of its β-cyclodextrin complex to beagle dogs was investigated in comparison with that of CN alone. The dissolution rate at pH 3.0-6.8 was increased significantly by inclusion complexation, but there was no difference in the bioavailability of CN after oral administration of β-cylodextrin complex and that of CN alone. The absorption of CN was decreased significantly when CN was administered with NaHCO3. However, no decrease was… 
Enhancement of bioavailability of cinnarizine from its beta-cyclodextrin complex on oral administration with DL-phenylalanine as a competing agent.
Evaluating the competing effect of DL-phenylalanine in vitro using an absorption simulator, it was found that the decreased penetration rate of cinnarizine through the artificial lipid barrier with addition of beta-cyclodextrin was restored with the addition of DL.
β‐Cyclodextrin Derivatives, SBE4‐β‐CD and HP–β‐CD, Increase the Oral Bioavailability of Cinnarizine in Beagle Dogs
The absolute bioavailabilities (Fabs) of cinnarizine after oral administration as two modified beta-cyclodextrin (SBE4-beta-CD or HP-beta-CD) solutions, an aqueous suspension, and two capsules in
Inclusion complex of cinnarizine withβ-cyclodextrin in aqueous solution and in solid state
Inclusion complex formation of cinnarizine (CN) with β-cyclodextrin (β-CD) in aqueous solution and in solid state was confirmed by the solubility method, powder X-ray diffractometry, differential
Enhancement of the oral bioavailability of cinnarizine in oleic acid in beagle dogs.
The present study was an attempt to develop a new dosage form of cinnarizine, which is slightly soluble in water, using lipid as a vehicle, and it was found that cinnARizine dissolved well in oleic and linoleic acids.
Inclusion Complexation of 4-Biphenylacetic Acid with β-Cyclodextrin
AbstractThe preparation of an inclusion complex of 4-biphenylacetic acid (BPAA), a non-steroidal antiinflammatory drug, with β-cyclo-dextrin is described. The presumible structure of the inclusion
Formation arid antimicrobial activity of complexes of β-cyclodextrin and some antimycotic imidazole derivatives
Complex formation between β-cyclodextrin and six antimycotic imidazole derivatives has been studied. The solubility of all drugs was increased in the presence of β-cyclodextrin. The smallest increase
Drug/cyclodextrin/hydroxy acid multicomponent systems. Properties and pharmaceutical applications.
The objective of this mini-review is to summarize the findings concerning the properties and the pharmaceutical applications of multicomponent complexes made of a sparingly water-soluble amino-type
Complexation and solubility behavior of albendazole with some cyclodextrins.
The main purpose of this work was to study the albendazole-cyclodextrins complexation equilibrium and to propose a suitable excipient to improve the solubility behavior and dissolution rate of
Cyclodextrins in the Pharmaceutical Field
AbstractCyclodextrins (CyDs) are cyclic oligosaccharides, containing a minimum of six D-(+)-glycopyranose units attached by α-1, 4-linkages produced by the action of the
Cyclodextrins, Their Value in Pharmaceutical Technology
Cyclodextrins are cyclic oligosaccharides consisting of a variable number of glucose units (usually 6 to 81. The ring formed by cyclodextrins is externally very hydrophilic and relatively apolar
