Formulations containing nanosized drug particles such
as nanocrystals
and nanosized amorphous drug aggregates recently came into light as
promising strategies to improve the bioavailability of poorly soluble
drugs. However, the increased solubility due to the reduction in particle
size cannot adequately explain the enhanced bioavailability. In this
study, the mechanisms and extent of enhanced passive permeation by
drug particles were investigated using atazanavir, lopinavir, and
clotrimazole as model drugs. Franz diffusion cells with lipid-infused
membranes were utilized to evaluate transmembrane flux. The impact
of stirring rate, receiver buffer condition, and particle size was
investigated, and mass transport analyses were conducted to calculate
transmembrane flux. Flux enhancement by particles was found to be
dependent on particle size as well as the partitioning behavior of
the drug between the receiver solution and the membrane, which is
determined by both the drug and buffer used. A flux plateau was observed
at high particle concentrations above amorphous solubility, confirming
that mass transfer of amorphous drug particles from the aqueous solution
to the membrane occurs only through the molecularly dissolved drug.
Mass transport models were used to calculate flux enhancement by particles
for various drugs at different conditions. Good agreements were obtained
between experimental and predicted values. These results should contribute
to improved bioavailability prediction of nanosized drug particles
and better design of formulations containing colloidal drug particles.

Abstract
The spontaneous formation of amorphous drug nanoparticles following the release of a drug from a supersaturating formulation is gaining increasing attention due to their potential contribution to increased oral bioavailability. The formation of nanosized drug particles also has considerable implications for the interpretation of in vitro and in vivo data. However, the membrane transport properties of these drug particles remain less well understood. Herein, the membrane permeation of nanosized amorphous drug particles of a model drug atazanavir was evaluated using different artificial membrane-based, cell-based, and animal tissue-based models. Results showed that flux enhancement by particles was different for the various systems used. Generally, good agreement was obtained among experiments performed using the same apparatus with different model membranes, with the exception of the Madin-Darby canine kidney cell monolayer and the Long-Evans rat intestine tissue, which showed lower flux enhancements. Franz cell-based models showed slightly higher flux enhancements by particles compared to Transwell and intestinal tissue sac models. Mass transport analysis suggested that the extent of flux enhancement by particles is dependent on the geometry of the apparatus as well as the properties of the membrane and buffer used, whereas the flux plateau concentration is dependent on the unstirred water later (UWL) asymmetry. These results highlight the complexity in characterizing the permeability advantage of these nonmembrane permeable drug particles and suggest that caution should be used in selecting the appropriate in vitro model to evaluate the overall permeability of colloidal drug particles.

Abstract
Amorphous nanoparticles of curcumin (ANC) with primary particle sizes of 50 to 100 nm were prepared using a forced thin film reactor (FTFR). An ethanolic solution of curcumin and polyvinylpyrrolidone was mixed with purified water in an FTFR to precipitate the curcumin nanoparticles. In order to obtain amorphous particles, the solvent used and the operation conditions of FTFR such as the rotation speed of the disk and the flow rate of solutions were adjusted. According to powder X-ray diffraction (XRD) analysis and Fourier transform infrared spectroscopy (FT-IR), amorphous curcumin nanoparticles were obtained. To control the crystallinity, ultrasonic treatment was carried out on ANC suspended in water or hexane to which a polymer or a surfactant was added to prevent the growth of the particles. Transmission electron microscopy, XRD, and FT-IR analyses indicated that the treatment enabled the transformation of ANC to crystalline form 1 (a fundamental curcumin structure) and then to crystalline form 2 or crystalline form 3 without any change in the size of the primary particles. These findings suggest the possibility of preparing solid particles with a desired particle size and crystallinity.

Abstract
Curcumin is known to possess a wide range of pharmacological activities for the treatment of chronic or inflammatory diseases, Alzheimer's disease, and various cancers. However, the therapeutic efficacy of curcumin is restricted by its poor bioavailability after oral administration. In this study, the effects of various cyclodextrins on the intestinal absorption of curcumin were evaluated in rat intestine by an in situ closed-loop method. Among the tested cyclodextrins, 50 mM α-cyclodextrin significantly enhanced the absorption of curcumin without inducing any intestinal toxicity. The analysis of cellular transport across Caco-2 cell monolayers showed that 50 mM α-cyclodextrin reduced the transepithelial electrical resistance value of cell monolayers and improved the permeability of 5(6)-carboxyfluorescein, a poorly absorbable drug, which is mainly transported via a paracellular pathway. Furthermore, the western blotting analysis showed that α-cyclodextrin decreased the expression of claudin-4, a tight junction-associated protein, in brush border membrane vesicles. Additionally, α-cyclodextrin increased the membrane fluidity of lipid bilayers in brush border membrane vesicles and may also have promoted the permeation of drug molecules via a transcellular pathway. These results suggested that α-cyclodextrin might enhance the intestinal absorption of curcumin via both paracellular and transcellular pathways.
