Abstract
The potential use of natural cyclodextrins and their synthetic derivatives have been studied extensively in pharmaceutical research and development to modify certain properties of hydrophobic drugs. The ability of these host molecules of including guest molecules within their cavities improves notably the physicochemical properties of poorly soluble drugs, such as albendazole, the first chosen drug to treat gastrointestinal helminthic infections. Thus, the aim of this work was to synthesize a beta cyclodextrin citrate derivative, to analyze its ability to form complexes with albendazole and to evaluate its solubility and dissolution rate. The synthesis progress of the cyclodextrin derivative was followed by electrospray mass spectrometry and the acid-base titration of the product. The derivative exhibited an important drug affinity. Nuclear magnetic resonance experiments demonstrated that the tail and the aromatic ring of the drug were inside the cavity of the cyclodextrin derivative. The inclusion complex was prepared by spray drying and full characterized. The drug dissolution rate displayed exceptional results, achieving 100% drug release after 20 minutes. The studies indicated that the inclusion complex with the cyclodextrin derivative improved remarkably the physicochemical properties of albendazole, being a suitable excipient to design oral dosage forms.

Abstract
Cyclodextrins are useful functional excipients that have enjoyed widespread attention and use. The basis for this popularity from a pharmaceutical standpoint, is the ability of these materials to interact with poorly water-soluble drugs and drug candidates resulting in an increase in their apparent water solubility. The mechanism for this solubilization is rooted in the ability of cyclodextrin to form non-covalent dynamic inclusion complexes in solution. Other solubilizing attribute may include the ability to form non-inclusion based complexes, the formation of aggregates and related domains and the ability of cyclodextrins to form and stabilize supersaturated drug solutions. The increase in solubility also can increase dissolution rate and thus improve the oral bioavailability of BCS Class II and IV materials. A number of cyclodextrin-based products have reached the market based on their ability to camouflage undesirable physicochemical properties. This review is intended to give a general background to the use of cyclodextrin as solubilizers as well as highlight kinetic and thermodynamic tools and parameters useful in the study of drug solubilization by cyclodextrins.

Abstract
The temporal response to concentration changes external to a microdialysis probe containing trapping agents in the perfusion fluid was studied. Native beta-cyclodextrin and a water-soluble beta-cyclodextrin polymer were used as trapping agents in the microdialysis perfusion fluid to study the temporal concentration response to carbamazepine, a hydrophobic analyte. The temporal response of microdialysis probes containing antibody-immobilized microspheres against five different cytokines (tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), interleukin-2 (IL-2), IL-4, and IL-5) to concentration changes outside of the probe was also determined. In both cases, no delayed temporal response of enhanced microdialysis was observed for either carbamazepine or the cytokines as compared to standard microdialysis sampling procedures.

Abstract
Complex binding constants of 23 aliphatic acids with alpha-cyclodextrin in aqueous solution were measured by potentiometry, solubility, or competitive spectrophotometry at 25 degrees C. All systems formed 1:1 acid:cyclodextrin complexes, and some of them also formed 1:2 complexes. The conjugate acids formed stronger complexes than did the conjugate bases (except for glycine). Empirical correlations of complex stabilities are shown with partition coefficients, surface areas, molar refraction, and other descriptors. Complex stability appears to result from the hydrophobic effect, the dispersion interaction, and interaction of the carboxylic acid group with the cyclodextrin.

Abstract
Complex binding constants of the three native cyclodextrins with seven cyclohexane derivatives (all possessing the carboxylic acid group) and with the series C6H5(CH2)nCOOH (n = 0 to 4) were measured in aqueous solution at 25 degrees C by potentiometry and the solubility method. These results, combined with literature data, indicate that alpha- and gamma-cyclodextrins bind with comparable strength to both the cyclohexyl and phenyl moieties, with beta-cyclodextrin binding significantly more strongly. These acid series are compared with several series CH3(CH2)nX, where X is CH3, COOH, COO-, OH, SO3-, etc., and it is concluded that the X group (for X other than methyl) contributes appreciably to complex stability, perhaps by means of an extracavity interaction. The COOH group provides a further augmentation of complex stability. NMR CIS and ROESY results indicate the presence of isomeric complexes in both the cyclohexyl and phenylalkanoic series, and clearly demonstrate the existence of intracavity inclusion. An NOE study of the alpha-cyclodextrin: cyclohexanecarboxylate system provides evidence for inclusion combined with interaction outside (that is, at the rim of) the cavity.

Abstract
Proceeding from a phenomenological theory of pairwise interactions (solvent-solvent, solvent-solute, and solute-solute), the binding constant K11 (in M-1) for 1:1 complex formation by alpha-cyclodextrin at a substrate binding site, at 25 degrees C in water, is given by log K11 = -1.74 - [Z] + 0.032(-delta A), where [Z] incorporates solvent-solute (solvation) and solute-solute interactions and delta A is the decrease in nonpolar surface area (in A2 molecule-1) on the substrate that is exposed to solvent when the binding site enters the cyclodextrin cavity. delta A is estimated from the structure of the binding site. Three levels of approximation are described for estimating [Z]. At the third (highest) level, the procedure when applied to 569 complex systems generated predicted values of log K11 that agreed within 0.30 unit of the experimental values in 58% of cases, and that agreed within 1.00 unit in 95% of cases.

Abstract
A new methodology of pH-metric data treatment was developed to extract the stoichiometry and the thermodynamic association constants of guest-cyclodextrin inclusion complexes in dilute aqueous solution when the guest is a participant in an acid-base equilibrium. pH-metric titration curves in the presence of cyclodextrin (CD) were treated by a curve-fitting technique according to a nonlinear least-squares regression. Equations corresponding to the different kinds of acid-base pairs (AH/A-, BH+/B) and stoichiometries (1:1 and 1:2) were established. The methodology was validated by studying the 5-phenylbarbituric acid complexation with beta-CD and the 4-cyanobenzoic acid complexation with alpha-CD. Then it was applied to chlorpromazine. Both the acid form (constant K1 = 3260) and the base form (constant G1 = 13,100) gave complexes with beta-CD according to 1:1 stoichiometry.

Abstract
The competitive indicator method for studying molecular complexes is extended to systems forming 1:1 (SL) and 1:2 (SL2) complexes of substrate (S) and ligand (L). A modification is described for slightly soluble substrates, in which the presence of solid substrate establishes a constant concentration of uncomplexed substrate. These methods are applied to complexes of alpha-cyclodextrin with some aromatic substrates, with methyl orange as the indicator in acid solution; nitrazine yellow is introduced as an indicator for these studies in basic solution.
