Abstract
In this study, guesthost inclusion complexes of silver abietate with β-cyclodextrin were prepared by kneading and physical mixing techniques, and analyzed via fourier transformed infrared spectroscopy (FTIR) and thermogravimetric analyser (TGA). The 1:1 and 1:2 stoichiometry of the guesthost were prepared. Obtained FTIR and TGA results showed that formation of silver abietate:β-cyclodextrin (Ag-A:β-CD) inclusion complexes occurred at a mass ratio of both 1:1 and 1:2. Furthermore, prepared Ag-A:β-CD (1:2) inclusion complex was doped in Poly(vinyl alcohol) nanofibers during electrospinning process for obtaining nanowebs. The formation of nanowebs were investigated under scanning electron microscope (SEM), X-Ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR) and thermogravimetric analyser (TGA). The results confirmed Ag-A:β-CD inclusion complex containing Poly(vinyl alcohol) (PVA) nanoweb production.

Abstract
Cyclodextrins (CDs) are naturally occurring cyclic oligosaccharides containing
six (α-CD), seven (β-CD), eight (γ-CD) and more glucopyranose units linked with α-(1,4)
bonds, having a terminal hydrophilic part and central lipophilic cavity. α-, β- and γ-CDs
are widely used in many industrial products, technologies and analytical methods owing to
their unique, versatile and tunable characteristics. In the pharmaceutical industry, CDs are
used as complexing agents to enhance aqueous solubility, physico-chemical stability and
bio-availability of administered drugs. Herein, special attention is given to the use of α-, β-
and γ-CDs and their derivatives in different areas of drug and gene delivery systems in the
past few decades through various routes of administration with a major emphasis on the
more recent developments.

Abstract
AIM Binary and ternary complexes with hydroxypropyl-β-cyclodextrin (HPβCD), using glutamic acid (GA), proline or lysine as the third component, were developed to increase the solubility and the dissolution rate of norfloxacin (NOR). METHODS/RESULTS Complexation was evaluated by phase solubility studies, obtaining the highest NOR solubility with GA and HPβCD. Thermal analysis suggested that different kinds of interactions occur among NOR, HPβCD and each amino acid, and when the systems were prepared by kneading or by means of freeze-drying technique. Dissolution studies, performed on simulated gastric fluid and subsequent simulated intestinal fluid, showed the highest rate of NOR from NOR-HPβCD-GA. CONCLUSION NOR:HPβCD:GA was the best approach for improving the bioavailability of NOR.

Abstract
The objective of this study was to improve candesartan cilexetil (CC) efficacy by formulating nanocrystals via solid dispersion (SD) technique using tromethamine (Tris). SD was prepared by solvent evaporation at different drug carrier ratios, evaluated for particle size, vitro dissolution studies, TEM, FTIR, and X-ray powder diffraction. Ex vivo, in vivo pharmacokinetic parameters were conducted on selected formulae compared to drug suspension and marketed product. Size analysis demonstrated formation of particles in the nanorange lower than 300 nm. A burst drug release followed by an improved dissolution was observed indicating instant formation of nanocrystals along with amorphization as confirmed by X-ray diffraction. FTIR studies suggested the absence of chemical interaction between Tris and CC. TEM revealed formation of irregular oval nanoparticles. SD-1:5 has higher apparent permeability coefficient compared to CC suspension. Furthermore, the pharmacokinetic results proved the ability of the formed nanoparticles to enhance the efficacy of CC compared to drug suspension and marketed product. In conclusion, using of Tris as alkaline esterase activator carrier could be a promising tool to bypass the controversial effect of esterase enzymes that may be a source for inter-individual variations affecting ester prodrug candidates' efficacy.

Abstract
Econazole nitrate (EC) is an active, imidazole antifungal agent. However, low aqueous solubility and dissolution rate of EC has discouraged its usage for the treatment of ophthalmic fungal infection. In this study, inclusion complexes of EC with cyclodextrins were prepared to enhance its solubility, dissolution, and ocular bioavailability. To achieve this goal, EC was complexed with β-CyD/HP-β-CyD using kneading, co-precipitation, and freeze-drying techniques. Phase-solubility studies were performed to investigate the complexes in the liquid form. Additionally, the complexes in the solid form were characterized with Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), and transmission electron microscopy (TEM). Furthermore, different eye drops containing EC-CyD complexes were prepared using different polymers and then characterized regarding their drug contents, pH, viscosity, mucoadhesive strength, and in vitro release characteristics. The results showed that stable EC-CyD complexes were formed in 1:1 molar ratio as designated by BS-type diagram. Econazole nitrate water solubility was significantly increased in about three- and fourfold for β-CyD and HP-β-CyD, respectively. The results showed that the prepared complexes were spherical in shape having an average particle diameter from 110 to 288.33 nm with entrapment efficiency ranging from 64.24 to 95.27%. DSC investigations showed the formation of real inclusion complexes obtained with co-precipitation technique. From the in vitro studies, all eye drops containing co-precipitate complexes exhibited higher release rate than that of other complexes and followed the diffusion-controlled mechanism. In vivo study proved that eye drops containing EC-CyD complexes showed higher ocular bioavailability than EC alone which indicated by higher AUC, Cmax, and relative bioavailability values.

Abstract
Inclusion of drugs in cyclodextrins (CDs) is a recognized tool for modifying several properties such as solubility, stability, bioavailability, and so on. The photoreactive behavior of the β-CD/ketoprofen (KP) complex upon UV exposure showed a significant increase in photodecarboxylation, whereas the secondary degradation products by hydroxylation of the benzophenone moiety were inhibited. The results may account for an improvement of KP photophysical properties upon inclusion, thus better fostering its topical use. To correlate the structural details of the inclusion with these results, an NMR spectroscopic study of KP upon inclusion in β-CD was performed. Effects of the magnetically anisotropic centers of KP, changing their orientations upon inclusion and giving chemical shift variations, were specifically correlated with the results of the molecular dynamic simulations and ab initio calculations. In the large variety of papers focusing on the structural analysis of β-CD complexes, this work represents one of the few examples in which a detailed analysis of these simultaneous upfield-downfield NMR shifts of the same aromatic molecule upon inclusion is reported. Interestingly, the results demonstrate that the observed upfield and downfield shifts upon inclusion are not related to any direct magnetic role of β-CD. The conformational change of KP upon the inclusion process consists of a slight reduction in the angle between the two phenyl rings and in a remarkable reduction in the mobility of the carboxyl group, the latter being one of the main contributions to the NMR resonance shifts. These structural details help in understanding the features of the inclusion complex and, eventually, the driving force for its formation.

Analysis of physicochemical properties of ternary systems of oxaprozin with randomly methylated-ß-cyclodextrin and l-arginine aimed to improve the drug solubility. J Pharm Biomed Anal 2016; 129:350-358.

Abstract
The influence of l-arginine on the complexing and solubilizing power of randomly-methylated-β-cyclodextrin (RameβCD) towards oxaprozin, a very poorly soluble anti-inflammatory drug, was examined. The interactions between the components were investigated both in solution, by phase-solubility analysis, and in the solid state, by differential scanning calorimetry, FTIR and X-ray powder diffractometry. The morphology of the solid products was examined by Scanning Electron Microscopy. Results of phase-solubility studies indicated that addition of arginine enhanced the RameβCD complexing and solubilizing power of about 3.0 and 4.5 times, respectively, in comparison with the binary complex (both at pH≈6.8). The effect of arginine was not simply additive, but synergistic, being the ternary system solubility higher than the sum of those of the respective drug-CD and drug-arginine binary systems. Solid equimolar ternary systems were prepared by physical mixing, co-grinding, coevaporation and kneading techniques, to explore the effect of the preparation method on the physicochemical properties of the final products. The ternary co-ground product exhibited a dramatic increase in both drug dissolution efficiency and percent dissolved at 60min, whose values (83.6 and 97.1, respectively) were about 3 times higher than the sum of those given by the respective drug-CD and drug-aminoacid binary systems. Therefore, the ternary co-ground system with arginine and RameβCD appears as a very valuable product for the development of new more effective delivery systems of oxaprozin, with improved safety and bioavailability.

Abstract
Xiang-Fu-Si-Wu Decoction (XFSWD), a famous Chinese herbal formula, is considered an effective prescription for treating primary dysmenorrhea. The essential oil is a significant effective ingredient of XFSWD. However, its volatility, instability and poor water-solubility influence its pharmacodynamic effects. β-Cyclodextrin (β-CD) has the intrinsic ability to form specific inclusion complexes with such drugs to enhance their stability, solubility and bioavailability. The aim of this study was thus to compare the pharmacokinetic characteristics and the oral bioavailability of XFSWD essential oil (XEO) and its β-CD inclusion complex after oral administration to rats. A simple, rapid, and sensitive ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method was developed for the simultaneous quantification of five active components of XEO in rat plasma. The in vivo data showed that XEO/β-CD inclusion complex displayed higher maximum plasma concentration (Cmax), longer half-time (T1/2) and bigger area under the concentration-time curve (AUC0–24 h). These results demonstrated that the formation of β-CD inclusion complex has significantly increased the oral bioavailability of the drugs in rats than free oil.

Abstract
Biological barriers are the main defense systems of the homeostasis of the organism and protected organs. The blood-brain barrier (BBB), formed by the endothelial cells of brain capillaries, not only provides nutrients and protection to the central nervous system but also restricts the entry of drugs, emphasizing its importance in the treatment of neurological diseases. Cyclodextrins are increasingly used in human pharmacotherapy. Due to their favorable profile to form hydrophilic inclusion complexes with poorly soluble active pharmaceutical ingredients, they are present as excipients in many marketed drugs. Application of cyclodextrins is widespread in formulations for oral, parenteral, nasal, pulmonary, and skin delivery of drugs. Experimental and clinical data suggest that cyclodextrins can be used not only as excipients for centrally acting marketed drugs like antiepileptics, but also as active pharmaceutical ingredients to treat neurological diseases. Hydroxypropyl-β-cyclodextrin received orphan drug designation for the treatment of Niemann-Pick type C disease. In addition to this rare lysosomal storage disease with neurological symptoms, experimental research revealed the potential therapeutic use of cyclodextrins and cyclodextrin nanoparticles in neurodegenerative diseases, stroke, neuroinfections and brain tumors. In this context, the biological effects of cyclodextrins, their interaction with plasma membranes and extraction of different lipids are highly relevant at the level of the BBB.

Abstract
The association process of a host-guest system, cyclodextrins (CyD) - 3-carboxycoumarin acid (3CCA) was followed by means of UV-vis, circular dichroism and steady-state fluorescence spectroscopies in buffer solution at pH=1. The experimental data were analyzed in order to get information on the stoichiometry, the equilibrium constants and the geometry of the inclusion complexes. In the circular dichroism spectra, a positive induced signal was obtained reflecting that the guest penetrates the cavity in such a way that the transition moment of the electronic band is quasi parallel to the host main axis. The experimental data are supported by the DFT and TDDFT (B3LYP/6-31G) calculations performed on the isolated ligand and by TDDFT (ZINDO) calculations carried out on the supramolecular ligand-cyclodextrin system.

Abstract
Complexations between three oridonin derivatives and β-cyclodextrin (βCD) were studied by nuclear magnetic resonance (NMR) method. Job's plots for complexes were depicted by (1)H NMR spectra chemical shifts, which proved the 1:1 stoichiometry inclusion complex formation between each derivative and βCD. Two-dimensional rotating frame overhauser effect spectroscopy (2D ROESY) support the above conclusion and also proved that ring A of each oridonin derivative deeply enters into hydrophobic cavity from the wider rim and the other parts are outside the cavity. Apparent formation constants (Ka) of complexes between three oridonin derivatives and two CDs are calculated according to Scott's equation.
