Abstract
In spite of recent advances in targeted tumor therapy, systemic chemotherapy with cytotoxic agents remains a vital cancer treatment modality. Gemcitabine is a nucleoside analog commonly used in the treatment of various solid tumors, but an oral gemcitabine dosage form remain unavailable. Previously, we developed the 4-(N)-stearoyl gemcitabine solid lipid nanoparticles (GemC18-SLNs) by incorporating 4-(N)-stearoyl gemcitabine (GemC18), an amide prodrug of gemcitabine, into solid lipid nanoparticles. GemC18-SLNs, when administered intravenously, showed strong antitumor activity against various human and mouse tumors in mouse models. In the present study, we defined the plasma pharmacokinetics of gemcitabine when GemC18-SLNs were given orally to healthy mice and evaluated the antitumor activity of GemC18-SLNs when given orally in mouse models of lung cancer. In mice orally gavaged with GemC18-SLNs, plasma gemcitabine concentration followed an absorption phase and then clearance phase, with a Tmax of ~2 h. The absolute oral bioavailability of gemcitabine in the GemC18-SLNs was ~70% (based on AUC0-24 h values). In mice with pre-established tumors (i.e. mouse TC-1 or LLC lung cancer cells), oral GemC18-SLNs significantly inhibited the tumor growth and increased mouse survival time, as compared to the molar equivalent dose of gemcitabine hydrochloride or GemC18 in vegetable oil or in Tween 20. Immunohistostaining revealed that oral GemC18-SLNs also have significant antiproliferative, antiangiogenic, and proapoptotic activity in LLC tumors. Formulating a lipophilic amide prodrug of gemcitabine into solid lipid nanoparticles may represent a viable approach toward developing a safe and efficacious gemcitabine oral dosage form.

Abstract
Extracellular vesicles (EVs) are membrane-derived vesicles that are enriched with RNAs, proteins and other functional molecules. We exploit the unique physical properties of EVs as a promising and advantageous nanoplatform for the delivery of therapeutic drugs and genetic materials. Early successes in the discovery of various disease-related characteristics of EVs have driven a new wave of innovation in developing nanoscale drug-delivery systems (DDSs). Nevertheless, there are several issues that need to be considered during the development of these alternative DDSs, such as standardized isolation and preservation methods, efficient drug encapsulation, mechanisms of drug release and so on. In this mini-review, we summarize the current status and progress of EV-based DDSs as an efficient nanoplatform for therapeutics delivery, followed by a discussion on their challenges and future prospects for clinical translation and applications.

Abstract
The aim of the present research is to increase lipid solubility, metabolic stability and therapeutic efficacy of water soluble gemcitabine (GEM) via phospholipid complex (PC) formation. A novel phospholipid complex of GEM was successfully prepared and optimized. Physical interaction of GEM with phospholipid was evaluated by DSC, FT-IR, 1H NMR, 31P-NMR and P-XRD. SEM images of GEM-PC showed rough structure and TEM images of diluted aqueous dispersion of GEM-PC showed micellar structure. In silico study also revealed the significant interaction between drug and phospholipid. GEM-PC demonstrated sustained drug release pattern and high plasma stability (∼2.2 fold) in vitro as compared to GEM. Increased in vitro cytotoxicity and apoptosis were observed with GEM-PC, when incubated with human pancreas adenocarcinoma cell lines. In vivo pharmacokinetics showed the almost 2 fold increase in AUC0-∞ (area under curve) with phospholipid complex (8983.26ngh/ml) as compared with GEM (4371.18ngh/ml) and GEMITA (4689.29ngh/ml). Toxicity studies signify the safety of GEM-PC over GEMITA. Pharmacodynamics studies in pancreatic tumor model further revealed higher efficacy of GEM-PC than GEMITA. These findings suggested the higher potential of phospholipid based technology for the enhancement of metabolic stability and therapeutic efficacy of GEM.

Abstract
In this study, PLGA based nanoparticles of tenofovir disoproxil fumarate (TDF) were designed for enhancing its oral absorption. To develop PLGA based TDF nanoparticles with the goal of minimum particle size and maximum entrapment efficiency statistical optimization techniques (factorial design and response surface methodology) were employed. The optimized nanoparticles were characterized for size, shape, charge and physical state. Further, the stability, cytotoxicity and metabolic protective effect of the nanoparticles were evaluated. Single dose pharmacokinetic study in rats was conducted to evaluate the oral absorption of the designed nanoparticles. Ex vivo everted gut sac studies were performed to evaluate the role of active uptake mechanisms in the absorption of the designed nanoparticles. The results showed that the statistical models employed could determine the interaction effects of the critical factors which were used in the optimization of the nanoparticles. The optimized nanoparticles with a particle size of 218±3.85nm and an entrapment efficiency of 57.3±1.6%. The nanoparticles were able to increase the AUC of tenofovir by 5.8 fold. It was observed that active uptake mechanisms predominantly via clathrin-mediated uptake played a key role in increasing the oral absorption of TDF.

Abstract
Docetaxel (DTX), a cytotoxic taxane, is a poor water-soluble drug and exhibits less oral bioavailability. Current research investigates the effective transport, for DTX-loaded chitosan (CS)-coated-poly-lactide-co-glycolide (PLGA)-nanoparticles (NPs) (DTX-CS-PLGA-NPs) and DTX-PLGA-NPs as well as a novel third-generation P-gp inhibitor i.e. GF120918 (Elacridar), across intestinal epithelium with its successive uptake by the tumour cells in an in vitro model. The prepared NPs showed a spherical shape particle size i.e. <123.96 nm with polydispersity index (PDI) of <0.290 whereas for CS-coated NPs, the zeta potential was converted from negative to positive value along with a small modification in particle size distribution. The entrapment efficiency observed for DTX-CS-PLGA-NPs was 74.77%, whereas the in vitro release profile revealed an initial rapid DTX release followed by a sustained release pattern. For apparent permeability, DTX-CS-PLGA-NPs and DTX-PLGA-NPs along with GF120918 showed a five-fold (p < .01) and 2.2-fold enhancement, respectively, as observed in rat ileum permeation study. Similarly, for pharmacokinetic (PK) studies, higher oral bioavailability was observed from DTX-CS-PLGA-NPs (5.11-folds) and DTX-PLGA-NPs (3.29-folds) as compared with DTX-suspension (DTX-S). Cell uptake studies on A549 cells as performed for DTX-CS-PLGA-NPs and DTX-PLGA-NPs loaded with rhodamine 123 dye, exhibited enhanced uptake as compared with plain dye solution. The enhanced uptake for DTX-CS-PLGA-NPs and DTX-PLGA-NPs formulations in the presence of GF120918 was confirmed further with the help of confocal laser scanning microscopic images (CLSM). The potential of the third-generation novel P-gp inhibitor (GF120918) investigated for the effective delivery of DTX as well as investigation of permeability and uptake studies whereby a strong potential of GF120918 for effective oral delivery was established.

Abstract
Fisetin (FST), a potent anticancer phytoconstituent, exhibits poor aqueous solubility and hence poor bioavailability. The aim of the present study is to improve the oral bioavailability of FST by encapsulating into PLGA NPs (poly-lactide-co-glycolic acid nanoparticles) as a complex of HPβCD (hydroxyl propyl beta cyclodextrin) and to assess its anti-cancer activity against breast cancer cells. FST-HPβCD inclusion complex (FHIC) was prepared and the supramolecular complex formation was characterized by FTIR, DSC, PXRD and 1H NMR. FHIC encapsulated PLGA nanoparticles (FHIC-PNP) were prepared and were studied for in vitro anticancer activity, cellular uptake, apoptosis and reactive oxygen species generation in MCF-7 human breast cancer cells. Comparative bioavailability of FST was determined after oral administration in C57BL6 mice as pure FST and FHIC-PNP. The results revealed that FHIC-PNP not only enhanced the anti-cancer activity and apoptosis of FST against MCF-7 cells but also improved its oral bioavailability, as demonstrated by increased peak plasma concentration and total drug absorbed.

Abstract
The objective of this study was to prepare the ɛ-viniferine and vincristine-loaded PLGA-b-PEG nanoparticle and to investigate advantages of these formulations on the cytotoxicity of HepG2 cells. Prepared nanoparticle has shown a homogeneous distribution with 113 ± 0.43 nm particle size and 0.323 ± 0.01 polydispersity index. Zeta potential was determined as -35.03 ± 1.0 mV. The drug-loading percentages were 6.01 ± 0.23 and 2.01 ± 0.07 for ɛ-viniferine and vincristine, respectively. The cellular uptake efficiency of coumarin-6-loaded nanoparticles was increased up to 87.8% after 4 h. Nanoparticles loaded with high concentrations of both drugs showed a cytotoxic effect on HepG2 cells, having the percentage of cell viability of between 43.23% and 47.37%. Unfortunately, the percentage of apoptotic cells after treated with drugs-loaded nanaoparticles (10.93%) was similar to free forms of drugs (12.1%) that might be due to low ɛ-viniferine release in biological pH at 24 h.

Abstract
Hepatocellular carcinoma (HCC) is highly prevalent, and the third most common cause of cancer-associated deaths worldwide. HCC tumors respond poorly to chemotherapeutic anticancer agents due to inherent and acquired drug resistance, and low drug permeability. Targeted drug delivery systems with significant improvement in therapeutic efficiency are needed for successful HCC therapy. Here, we report the results of a technique optimized for the synthesis and formulation of antisense-miRNA-21 and gemcitabine (GEM) co-encapsulated PEGylated-PLGA nanoparticles (NPs) and their in vitro therapeutic efficacy in human HCC (Hep3B and HepG2) cells. Water-in-oil-in-water (w/o/w) double emulsion method was used to coload antisense-miRNA-21 and GEM in PEGylated-PLGA-NPs. The cellular uptake of NPs displayed time dependent increase of NPs concentration inside the cells. Cell viability analyses in HCC (Hep3B and HepG2) cells treated with antisense-miRNA-21 and GEM co-encapsulated NPs demonstrated a nanoparticle concentration dependent decrease in cell proliferation, and the maximum therapeutic efficiency was attained in cells treated with nanoparticles co-encapsulated with antisense-miRNA-21 and GEM. Flow cytometry analysis showed that control NPs and antisense-miRNA-21-loaded NPs are not cytotoxic to both HCC cell lines, whereas treatment with free GEM and GEM-loaded NPs resulted in ∼9% and ∼15% apoptosis, respectively. Cell cycle status analysis of both cell lines treated with free GEM or NPs loaded with GEM or antisense-miRNA-21 displayed a significant cell cycle arrest at the S-phase. Cellular pathway analysis indicated that Bcl2 expression was significantly upregulated in GEM treated cells, and as expected, PTEN expression was noticeably upregulated in cells treated with antisense-miRNA-21. In summary, we successfully synthesized PEGylated-PLGA nanoparticles co- encapsulated with antisense-miRNA-21 and GEM. These co-encapsulated nanoparticles revealed increased treatment efficacy in HCC cells, compared to cells treated with either antisense-miRNA-21- or GEM-loaded NPs at equal concentration, indicating that down-regulation of endogenous miRNA-21 function can reduce HCC cell viability and proliferation in response to GEM treatment.

Abstract
Unraveling the mechanisms of nanoparticle transport across the intestinal barrier is essential for designing more efficient nanoparticles for oral administration. The physicochemical parameters of the nanoparticles (e.g., size, surface charge, chemical composition) dictate nanoparticle fate across the intestinal barrier. This review aims to address the most important findings regarding polymeric and lipidic nanoparticle transport across the intestinal barrier, including the evaluation of critical physicochemical parameters of nanoparticles that affect nanocarrier interactions with the intestinal barrier.

Abstract
Gemcitabine (2',2'-difluoro-2'-deoxycytidine; dFdC) is an efficacious anticancer agent acting against a wide range of solid tumors, including pancreatic, non-small cell lung, bladder, breast, ovarian, thyroid and multiple myelomas. However, short plasma half-life due to metabolism by cytidine deaminase necessitates administration of high dose, which limits its medical applicability. Further, due to its hydrophilic nature, it cannot traverse cell membranes by passive diffusion and, therefore, enters via nucleoside transporters that may lead to drug resistance. To circumvent these limitations, macromolecular prodrugs and nanocarrier-based formulations of Gemcitabine are gaining wide recognition. The nanoformulations based approaches by virtue of their controlled release and targeted delivery have proved to improve bioavailability, increase therapeutic efficacy and reduce adverse effects of the drug. Furthermore, the combination of Gemcitabine with other anticancer agents as well as siRNAs using nanocarriers has also been investigated in order to enhance its therapeutic potential. This review deals with challenges and recent advances in the delivery of Gemcitabine with particular emphasis on macromolecular prodrugs and nanomedicines.

Abstract
Nanoparticles (NPs) can be absorbed via M cells of Peyer's patches after oral delivery leading to passive lymphatic targeting followed by systemic drug delivery. Hence, the study was aimed to formulate PLGA NPs of lopinavir. The NPs were prepared by nanoprecipitation, optimized by 33 factorial design and characterized by TEM, DSC, FTIR studies and safety was assessed by MTT assay. In vivo pharmacokinetic studies were performed in rats. The NPs were discrete spherical structures having particle size of 142.1 ± 2.13 nm and entrapment of 93.03 ± 1.27%. There was absence of drug-polymer interaction. Confocal images revealed the penetration and absorption of coumarin-loaded NPs in Caco-2 cells and intestine after oral delivery. There was 3.04 folds permeability and 13.9 folds bioavailability enhancement from NPs. The NPs can be promising delivery system for antiretroviral drug by delivering the drug to lymph (major HIV reservoir site) via direct absorption through intestine before reaching systemic circulation.

Abstract
Salmonella (S.) enterica infections are an important global health problem with more than 20 million individuals suffering from enteric fever annually and more than 200,000 lethal cases per year. Although enteric fever can be treated appropriately with antibiotics, an increasing number of antibiotic resistant Salmonella strains is detected. While two vaccines against typhoid fever are currently on the market, their availability in subtropical endemic areas is limited because these products need to be kept in uninterrupted cold chains. Hence, the development of a thermally stable vaccine that induces mucosal immune responses would greatly improve human health in endemic areas. Here, we have combined the high structural stability of Salmonella typhi outer membrane proteins (porins) with their microencapsulation into poly(lactic-co-glycolic acid) (PLGA) to generate an orally applicable vaccine. Encapsulated porins were protected from acidic degradation and exhibited enhanced immunogenicity following oral administration. In particular, the vaccine elicited strong S. typhi-specific B cell responses in Peyer's patches and mesenteric lymph nodes. In sum, PLGA microencapsulation substantially improved the efficacy of oral vaccination against S. typhi.

Abstract
Purpose Curcumin (CUR), the main polyphenol in turmeric, is poorly absorbed and rapidly metabolized following oral administration, which severely curtails its bioavailability. Poly-(lactic-co-glycolic acid)-based CUR nanoparticles (CUR-NP) have recently been suggested to improve CUR bioavailability, but this has not been fully verified. Specifically, no data are available about curcumin glucuronide (CURG), the major metabolite of CUR found in the plasma following oral administration of CUR-NP. Herein, we investigated the absorption and metabolism of CUR-NP and evaluated whether CUR-NP improves CUR bioavailability. Methods Following oral administration of CUR-NP in rats, we analyzed the plasma and organ distribution of CUR and its metabolites using high-performance liquid chromatography-tandem mass spectrometry. To elucidate the mechanism of increased intestinal absorption of CUR-NP, we prepared mixed micelles comprised of phosphatidylcholine and bile salts and examined the micellar solubility of CUR-NP. Additionally, we investigated the cellular incorporation of the resultant micelles into differentiated Caco-2 human intestinal cells. Results Following in vivo administration of CUR-NP, CUR was effectively absorbed and present mainly as CURG in the plasma which contained significant amounts of the metabolite compared with other organs. Thus, CUR-NP increased intestinal absorption of CUR rather than decreasing metabolic degradation and conversion to other metabolites. In vitro, CUR encapsulated in CUR-NP was solubilized in mixed micelles; however, whether the micelles contained CUR or CUR-NP had little influence on cellular uptake efficiency. Therefore, we suggest that the high solubilization capacity of CUR-NP in mixed micelles, rather than cellular uptake efficiency, explains the high intestinal absorption of CUR-NP in vivo. Conclusion These findings provide a better understanding of the bioavailability of CUR and CUR-NP following oral administration. To improve the bioavailability of CUR, future studies should focus on enhancing the resistance to metabolic degradation and conversion of CUR to other metabolites, which may lead to novel discoveries regarding food function and disease prevention.

Abstract
AIM Ergosterol is a plant sterol with anti-tumor and anti-angiogenic activities, but is poorly soluble. In this study, we attempted to enhance its anti-tumor action and oral bioavailability via poly(lactide-co-glycolide) (PLGA) nanoparticle encapsulation. METHODS Ergosterol-loaded PLGA nanoparticles (NPs/Erg) were prepared using the emulsion/solvent evaporation technique. Their physicochemical properties were characterized, and their cytotoxicity against human cancer cell lines was evaluated with MTT assay. The pharmacokinetics and tissue distribution of NPs/Erg were investigated in rats and mice, respectively. RESULTS NPs/Erg were spherical in shape with a particle size of 156.9±4.8 nm and a Zeta potential of -19.27±1.13 mV, and had acceptable encapsulation efficiency and loading capacity. NPs/Erg exerted much stronger cytotoxicity against human cancer cells than the free ergosterol, and showed significantly reduced IC50 values (14.69±0.48 μg/mL in glioma U251 cells; 9.43±0.52 μg/mL in breast cancer MCF-7 cells; 4.70±0.41 μg/mL in hepatoma HepG2 cells). After oral administration of a single dose in rats, NPs/Erg displayed a prolonged plasma circulation with a 4.9-fold increase of oral bioavailability compared with the free ergosterol. After mice received NPs/Erg, the ergosterol in NPs/Erg was rapidly distributed in stomach, kidneys, liver, brain, spleen, and virtually non-existent in heart and lungs. The presence of NPs/Erg in brain was particularly improved compared with the free ergosterol. CONCLUSION The PLGA nanoparticles serve as a promising carrier for the poorly soluble ergosterol and significantly improve its bioavailability, biodistribution and in vitro anti-tumor activities.

Abstract
Epirubicin (EPI) is a P-gp substrate antracycline analogue which elicits poor oral bioavailability. In the present work, EPI loaded poly-lactide-co-glycolic acid nanoparticles (PLGA-NPs) were prepared by double emulsion approach and superficially decorated with polyethylene glycol (EPI-PNPs) and mannosamine (EPI-MNPs). Average hydrodynamic particle size of EPI-PNPs and EPI-MNPs was found 248.63 ± 12.36 and 254.23 ± 15.16 nm, respectively. Cytotoxicity studies were performed against human breast adenocarcinoma cell lines (MCF-7) confirmed the superiority of EPI-PNPs and EPI-MNPs over free epirubicin solution (EPI-S). Further, confocal laser scanning microscopy (CLSM) and flow cytometric analysis (FACS) demonstrated enhanced drug uptake through EPI-PNPs and EPI-MNPs and elucidated dominance of caveolae mediated endocytosis for NPs uptake. Cellular transport conducted on human colon adenocarcinoma cell line (Caco-2) showed 2.45 and 3.17 folds higher permeability of EPI through EPI-PNPs and EPI-MNPs when compared with EPI-S (p<0.001) while permeability of EPI was found 5.23 and 5.67 folds higher across rat ileum, respectively. Furthermore, pharmacokinetic studies demonstrated 4.7 and 5.57 folds higher oral bioavailability through EPI-PNPs and EPI-MNPs when compared with EPI-S. In addition, both, EPI-PNPs and EMNPs showed tumor suppression comparable to indicated route (i.v. injection). EPI-MNPs showed 1.18 folds higher bioavailability and better tumor suppression than EPI-PNPs.

Abstract
Nanomaterials, like nanoparticles, micelles, nano-sheets, nanotubes and quantum dots, have great potentials in biomedical fields. However, their delivery is highly limited by the formation of protein corona upon interaction with endogenous proteins. This new identity, instead of nanomaterial itself, would be the real substance the organs and cells firstly encounter. Consequently, the behavior of nanomaterials in vivo is uncontrollable and some undesired effects may occur, like rapid clearance from blood stream; risk of capillary blockage; loss of targeting capacity; and potential toxicity. Therefore, protein-nanomaterial interaction is a great challenge for nanomaterial systems and should be inhibited. However, this interaction can also be used to functionalize nanomaterials by forming a selected protein corona. Unlike other decoration using exogenous molecules, nanomaterials functionalized by selected protein corona using endogenous proteins would have greater promise for clinical use. In this review, we aim to provide a comprehensive understanding of protein-nanomaterial interaction. Importantly, a discussion about how to use such interaction is launched and some possible applications of such interaction for advanced drug delivery are presented.

Abstract
Poly(lactic acid) (PLA) or poly(lactic acid)-poly(ethylene glycol) (PLA-PEG) blend nanoparticles were developed loading 5-fluorouracil (5-FU), an antitumor agent broadly used in therapy. A 2(3) factorial experimental design was conducted to indicate an optimal formulation and demonstrate the influence of the interactions of components on the mean particle size and drug encapsulation efficiency. Optimized PLA nanoparticles presented 294nm and 51% of 5-FU encapsulation efficiency and PLA-PEG blend nanoparticles presented 283nm and 55% of 5-FU encapsulation efficiency. In vitro release assay demonstrated after 320h about 50% of 5-FU was released from PLA and PLA-PEG blend nanoparticles. Release kinetics of 5-FU from nanoparticles followed second order and the release mechanism calculated by Korsmeyer-Peppas model was diffusion and erosion. In the assessment of cytotoxicity over Hep-2 tumor cells, PLA or PLA-PEG blend nanoparticles presented similar IC50 value than free 5-FU. Pharmacokinetic parameters after oral administration of 5-FU were improved by nanoencapsulation. Bioavailability, Cmax, Tmax, t1/2 and distribution volume were significantly improved, while clearance were decreased. PEG presence in nanoparticles didn't influence physicochemical and biological parameters evaluated. PLA and PLA-PEG nanoparticles can be potential carriers for oral delivery of 5-FU.

Abstract
The aim of this study was to improve the solubility of lutein through the use of chitosan (CS)/poly-γ-glutamic acid (γ-PGA) nanoencapsulation. In terms of redispersibility, water-soluble chitosan (WsCS)/γ-PGA nanoparticles (NPs) were better than insoluble chitosan (InCS)/γ-PGA NPs. The lutein-loaded WsCS/γ-PGA NP has a spherical form with a size around 200nm and a narrow size distribution (PDI<0.1). Solubility measures showed that nanoencapsulation of lutein into WsCS/γ-PGA NPs resulted in a significant 12-fold higher solubility compared to that of non-nanoencapsulated lutein (p<0.05). The redispersibility index of the lutein-loaded NPs was 1.01, indicating that they were completely reconstituted into aqueous solution as same as original aqueous solution. These results suggest that WsCS/γ-PGA nanoencapsulation can be used to enhance the solubility of lutein and other poorly water-soluble compounds.

Abstract
Fenretinide is an anticancer drug with low water solubility and poor bioavailability. The goal of this study was to develop biodegradable polymeric nanoparticles of fenretinide with the intent of increasing its apparent aqueous solubility and intestinal permeability. Three biodegradable polymers were investigated for this purpose: two different poly lactide-co-glycolide (PLGA) polymers, one acid terminated and one ester terminated, and one poly lactide-co-glycolide/polyethylene glycol (PLGA/PEG) diblock copolymer. Nanoparticles were obtained by using an emulsification solvent evaporation technique. The formulations were characterized by differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and particle size analysis. Dissolution studies and Caco-2 cell permeation studies were also carried out for all formulations. Ultra high performance liquid chromatography coupled with mass spectrometry (UPLC/MS) and ultraviolet detection was used for the quantitative determination of fenretinide. Drug loading and the type of polymer affected the nanoparticles' physical properties, drug release rate, and cell permeability. While the acid terminated PLGA nanoparticles performed the best in drug release, the ester terminated PLGA nanoparticles performed the best in the Caco-2 cell permeability assays. The PLGA/PEG copolymer nanoparticles performed better than the formulations with ester terminated PLGA in terms of drug release but had the poorest performance in terms of cell permeation. All three categories of formulations performed better than the drug alone in both drug release and cell permeation studies.

Abstract
Epirubicin (EPI) is an anthracycline antineoplastic agent, commercially available for intravenous administration only and its oral ingestion continues to remain a challenge. Present investigation is aimed at the development of poly-lactic-co-glycolic acid (PLGA) nanoparticles (NPs) for oral bioavailability enhancement of epirubicin. Developed formulation revealed particle size, 235.3±15.12 nm, zeta potential, -27.5±0.7 mV and drug content (39.12±2.13 μg/mg), with spherical shape and smooth surface. Cytotoxicity studies conducted on human breast adenocarcinoma cell lines (MCF-7) confirmed the superiority of epirubicin loaded poly-lactic-co-glycolic acid nanoparticles (EPI-NPs) over free epirubicin solution (EPI-S). Further, flow cytometric analysis demonstrated improved drug uptake through EPI-NPs and elucidated the dominance of caveolae mediated endocytosis for nanoparticles uptake. Transport study accomplished on human colon adenocarcinoma cell line (Caco-2) showed 2.76 fold improvement in permeability for EPI-NPs as compared to EPI-S (p<0.001) whereas a 4.49 fold higher transport was observed on rat ileum; a 1.8 fold higher (p<0.01) in comparison to Caco-2 cell lines which confirms the significant role of Peyer's patches in absorption enhancement. Furthermore, in vivo pharmacokinetic studies also revealed 3.9 fold improvement in oral bioavailability of EPI through EPI-NPs. Henceforth, EPI-NPs is a promising approach to replace pre-existing intravenous therapy thus providing "patient care at home".

Abstract
A variety of nanoscale delivery systems have been shown to enhance the oral absorption of poorly water-soluble and poorly permeable drugs. However, the performance of these systems has seldom been evaluated simultaneously. The aim of this study was to compare the bioavailability enhancement effect of lipid-based nanocarriers with poly(lactic-co-glycolic acid) (PLGA) nanoparticles (NPs) to highlight the importance of the lipid composition, with cyclosporine A (CyA) as a model drug. CyA-loaded PLGA NPs, nanostructured lipid carriers (NLCs), and self-microemulsifying drug-delivery systems (SMEDDS) were prepared. The particle size of PLGA NPs (182.2±12.8 nm) was larger than that of NLCs (89.7±9.0 nm) and SMEDDS (26.9±1.9 nm). All vehicles are charged negatively. The entrapment efficiency of PLGA NPs and NLCs was 87.6%±1.6% and 80.3%±0.6%, respectively. In vitro release tests indicated that the cumulative release of CyA was lower than 4% from all vehicles, including Sandimmun Neoral®, according to the dialysis method. Both NLCs and SMEDDS showed high relative oral bioavailability, 111.8% and 73.6%, respectively, after oral gavage administration to beagle dogs, which was not statistically different from commercial Sandimmun Neoral®. However, PLGA NPs failed to achieve efficient absorption, with relative bioavailability of about 22.7%. It is concluded that lipid-based nanoscale drug-delivery systems are superior to polymeric NPs in enhancing oral bioavailability of poorly water-soluble and poorly permeable drugs.
