Abstract
Estimating the dissolution behavior of a solid in the nasal mucus is challenging for solid dosage forms designed for the nasal application as the solid dissolves into nasal mucus and permeates through the mucosa. In the current study, the dissolution behavior of powders in the artificial nasal fluid was investigated using a 3D-printed chamber system to establish in vitro evaluation system for the dissolution of solid formulations that can simulate the intranasal environment in vivo. The dissolution rates of the five model drugs correlated with their solubility (r2 = 0.956, p < 0.01). The permeation rate of drugs across the Calu-3 cell layers after powder application depends on the membrane permeability of the drug. An analysis of membrane permeability considering the dissolution of powders showed the possibility of characterizing whether the drug in the powder was dissolution-limited or permeation-limited. This suggests that critical information can be obtained to understand which mechanism is more effective for the improvement of drug absorption from powders. This study indicates that the elucidation of drug dissolution behavior into nasal mucus is an important factor for the formulation of nasal powders and that the in vitro system developed could be a useful tool.

Abstract
Demonstration of bioequivalence of locally acting nasal spray formulations is a challenging task and the regulatory agencies have different approach towards this goal. The pharmacokinetic bioequivalence studies are recognized as necessary for assessment of equivalent systemic exposure. We utilized three different in vitro methods for nasal spray evaluation and compared those results with the results of pharmacokinetic studies of different formulations of four intranasal corticosteroids, in order to evaluate their in vivo relevance. Two cell lines, RPMI 2650 and Calu-3, Transwell® polycarbonate membranes with different pore size and lipid-oil-lipid tri-layer membrane in the parallel artificial membrane permeability assay (PAMPA) system were used for this purpose. The in vitro results correlated with the results of pharmacokinetic studies and correctly predicted (non)equivalence of the nasal sprays, showing that in vitro methods are good indicator of the in vivo outcome. The Transwell® and PAMPA in vitro methods were additionally implemented for testing batch-to-batch variability of reference nasal spray formulations. The results from the Transwell® assay for the two poorly soluble corticosteroids are possibly over-discriminatory in showing differences between batches of reference nasal sprays. Overall, the three in vitro methods have potential to predict the results of bioequivalence testing of nasal spray products.

Abstract
Background: As part of the efforts to find natural alternatives for cancer treatment and to overcome the barriers of cellular resistance to chemotherapeutic agents, polymeric nanocapsules containing curcumin and/or methotrexate were prepared by an interfacial deposition of preformed polymer method. Methods: Physicochemical properties, drug release experiments and in vitro cytotoxicity of these nanocapsules were performed against the Calu-3 lung cancer cell line. Results: The colloidal suspensions of nanocapsules showed suitable size (287 to 325 nm), negative charge (-33 to -41 mV) and high encapsulation efficiency (82.4 to 99.4%). Spherical particles at nanoscale dimensions were observed by scanning electron microscopy. X-ray diffraction analysis indicated that nanocapsules exhibited a non-crystalline pattern with a remarkable decrease of crystalline peaks of the raw materials. Fourier-transform infrared spectra demonstrated no chemical bond between the drug(s) and polymers. Drug release experiments evidenced a controlled release pattern with no burst effect for nanocapsules containing curcumin and/or methotrexate. The nanoformulation containing curcumin and methotrexate (NCUR/MTX-2) statistically decreased the cell viability of Calu-3. The fluorescence and morphological analyses presented a predominance of early apoptosis and late apoptosis as the main death mechanisms for Calu-3. Conclusions: Curcumin and methotrexate co-loaded nanocapsules can be further used as a novel therapeutic strategy for treating non-small-cell lung cancer.

Abstract
In the present study we investigated polymer-lipid microparticles loaded with ropinirole hydrochloride (RH) for nasal delivery. RH microparticles were further evaluated by means of scanning electron microscopy (SEM), ζ-potential measurements, Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and x-ray diffraction (XRD). In vitro release studies were performed in simulated nasal electrolyte solution (SNES) pH5.5 at 35°C. Ex vivo permeation studies were conducted across sheep nasal mucosa. Cytocompatibility was tested in cultured human airway epithelial cells (Calu-3). SEM studies revealed spheroid microparticles in the range of 2.09μm to 2.41μm. The presence of trimethylchitosan (TMC) induced a slight shift towards less negative ζ-potential values. Surface chemistry (XPS) revealed the presence of dipalmitoylphospatidylcholine (DPPC) and poly(lactic-co-glycolic acid) (PLGA) onto microparticles' surface, further corroborating the FT-IR and XRD findings. In vitro release studies showed that the microparticle composition can partly modulate the release of RH. Ex vivo studies demonstrated a 2.35-folded enhancement of RH permeation when RH was co-formulated with TMC of low molecular weight, compared to the control. All formulations tested were found to be non-toxic to cells. The results suggest that polymer-lipid microparticles may be a promising carrier for the nasal delivery of RH.

Abstract
INTRODUCTION Organic cation transporters (OCT) have been shown to mediate the transport of inhaled drugs in bronchial epithelial cells and might have important physiological functions in the airway epithelium. However, a quantitative method to evaluate OCT protein expression in physiologically relevant airway epithelial cell culture models is currently lacking. In-cell Western™ (ICW) techniques might fill that gap but to date, have only been performed on cells grown on 96 or 384-well microplates. METHODS An ICW assay was designed for measuring levels of the different OCT subtypes in intact layers of the human bronchial epithelial Calu-3 cell line cultured at an air-liquid interface on Transwell(®) inserts. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was used as the internal standard for normalisation of cell number between the layers. The protocol was subsequently validated by exposing cell layers to compounds known to cause variations in OCT expression. RESULTS Antibody signals above the background fluorescence were detected for OCT1, OCT3, OCTN1 and OCTN2 but not for OCT2 in 21day old Calu-3 layers, in agreement with previous studies which had reported OCT2 was absent in the Calu-3 cell line. Furthermore, increases in the fluorescence signal associated with OCT1, OCTN1 and OCTN2 were obtained following treatment of the layers with, respectively, the nitric oxide inducer sodium nitroprusside, the peroxisome proliferator activated receptor α (PPARα) agonist fenofibrate or the PPARγ agonist rosiglitazone, confirming the reliability of the ICW method developed. However, a suitable positive control for OCT3 could not be identified. DISCUSSION This novel ICW assay can be exploited to quantify basal OCT protein expression as well as changes in transporter levels following external stimuli in various in vitro models. It can also be easily adapted to probe any protein in epithelial layers maintained on permeable filters.
