Abstract
Introduction Limited aqueous solubility and subsequent poor absorption and low bioavailability are the main challenges in oral drug delivery. Solid dispersion is a widely used formulation strategy to overcome this problem. Despite their efficiency, drug crystallization tendency and poor physical stability limited their commercial use. To overcome this defect, ternary solid dispersions of glyburide: sodium lauryl sulfate (SLS) and polyethylene glycol 4000 (PEG), were developed using the fusion (F) and solvent evaporation (SE) techniques and subsequently evaluated and compared. Materials and Methods Physicochemical and dissolution properties of the prepared ternary solid dispersions were evaluated using differential scanning calorimetry (DSC), infrared spectroscopy (FTIR), and dissolution test. Flow properties were also assessed using Carr's index and Hausner's ratio. The physical stability of the formulations was evaluated initially and after 12 months by comparing dissolution properties. Results Formulations prepared by both methods similarly showed significant improvements in dissolution efficiency and mean dissolution time compared to the pure drug. However, formulations that were prepared by SE showed a greater dissolution rate during the initial phase of dissolution. Also, after a 12-month follow-up, no significant change was observed in the mentioned parameters. The results of the infrared spectroscopy indicated that there was no chemical interaction between the drug and the polymer. The absence of endotherms related to the pure drug from thermograms of the prepared formulations could be indicative of reduced crystallinity or the gradual dissolving of the drug in the molten polymer. Moreover, formulations prepared by the SE technique revealed superior flowability and compressibility in comparison with the pure drug and physical mixture (ANOVA, P < 0.05). Conclusion Efficient ternary solid dispersions of glyburide were successfully prepared by F and SE methods. Solid dispersions prepared by SE, in addition to increasing the dissolution properties and the possibility of improving the bioavailability of the drug, showed acceptable long-term physical stability with remarkably improved flowability and compressibility features.

Abstract
Poor aqueous solubility of both, existing drug molecules and those which are currently in the developmental stage, have posed a great challenge to pharmaceutical scientists because they often exhibit poor dissolution behavior and subsequent poor and erratic bioavailability. This has triggered extensive research to explore nanotechnology-based technology platforms for possible rescue. Recently, nanofibers have been exploited widely for diverse biomedical applications including for drug delivery. Electrospun nanofibers are capable of preserving the homogeneously loaded therapeutic agents in amorphous state potentialy impairing devitrification. The present review aims at providing an overview of the various key factors that affect the electrospinning process and characteristics of the nanofibers while fabrication of drug loaded nanofibers for poorly soluble drug candidates. The review explores various methodological advancements in the electrospinning process and set-ups for production scale-up. The various types of electrospun nanofibers (like simple matrix, core-sheath, Janus, and inclusion complex nanofibers) that have been exploited for the delivery of poorly soluble drugs are also critically assessed. This article is categorized under: Therapeutic Approaches and Drug Discovery > Emerging Technologies.

Abstract
Up to 90% of all newly developed active pharmaceutical ingredients (APIs) are poorly water soluble, most likely also showing a low oral bioavailability. In order to increase the aqueous solubility of these APIs, surfactants are promising excipients to increase both solubility and consequently bioavailability (e.g., in lipid- and surfactant-based drug delivery systems). In this work, we investigated the influence of hydrophobic and hydrophilic chain lengths of CiEj surfactants (C8E6, C10E6, and C10E8) toward the solubilization of fenofibrate, naproxen, and lidocaine. Furthermore, we investigated the partitioning of these APIs between the surfactant aggregates and the surrounding aqueous bulk phase. For all APIs considered, we determined the locus of API solubilization as well as the individual aggregation numbers (Nagg) of surfactants and API molecules in an API/surfactant aggregate. We further determined the hydrodynamic radius (Rh) of the API/surfactant aggregates in the absence and presence of the APIs. The size of the API/surfactant aggregates (Nagg, Rh) passes through a minimum upon lidocaine solubilization; it gradually increases upon naproxen solubilization and is almost constant upon fenofibrate solubilization. The results give valuable insights into the solubilization mechanisms of APIs in the CiEj surfactant aggregates. Our results reveal that fenofibrate is solely solubilized in the hydrophobic core of the CiEj surfactant aggregates, as only the hydrophobic chain length of the surfactant influences its solubilization. Naproxen is solubilized in the palisade layer of the surfactant aggregates, as both the hydrophobic and hydrophilic chain lengths are decisive for its solubilization. Lidocaine is mainly solubilized in the rather hydrophilic corona region of the surfactant aggregates, as the hydrophilic chain length of the surfactant governs its solubilization. The results further reveal that the hydrophilic/lipophilic balance is not an appropriate measure to estimate the solubilization capacity of surfactant aggregates.

Abstract
Silk fibroin nanofibers find broader applications in skin tissue engineering as wound dressings. In this study, we have prepared biocompatible collagen-coated silk fibroin nanofibers with two small molecules: sinomenine hydrochloride (SH) and kaempferol hydrate (KH) with bioactive properties for wound healing applications. The prepared nanofibrous scaffolds were characterized via different experimental techniques and the biocompatibility of the nanofibrous scaffolds was assessed using MTT assay and live/dead cell assay. The wound healing potential of the nanofibrous scaffolds was evaluated through in vivo animal model. Notably, the collagen-coated scaffolds showed improved biocompatibility and fibroblast viability over the uncoated scaffolds. The collagen-coated silk nanofibers containing KH showed good antioxidant properties and promoted wound healing in in vivo studies by minimizing inflammation and enhancing collagen deposition. Thus, the incorporation of antioxidant molecules along with collagen coating enhanced the wound healing efficiency of silk nanofibers.

Abstract
Surfactants and cosolvents are often combined to solubilize insoluble drugs in commercially available intravenous formulations to achieve better solubilization. In this study, six marketed parenteral formulations with surfactants and cosolvents were investigated on the aggregation processes of micelles, the structural characterization of micelles, and the properties of solvent using molecular dynamics simulations. The addition of cosolvents resulted in better hydration of the core and palisade regions of micelles and an increase in both radius of gyration (Rg) and the solvent accessible surface area (SASA), causing a rise in critical micelle concentration (CMC), which hindered the phase separation of micelles. At the same time, the presence of cosolvents disrupted the hydrogen bonding structure of water in solution, increasing the solubility of insoluble medicines. Therefore, the solubilization mechanism of the cosolvent and surfactant mixtures was successfully analyzed by molecular dynamics simulation, which will benefit future formulation development for drug delivery.

Abstract
Rhizomes of the plant Curcuma longa has been traditionally used in medicine and culinary practices in India. It possesses various pharmacological effect, namely, antioxidant, hepatoprotective, anti-inflammatory, anti-thrombosis, and anti-apoptotic. The study was undertaken to assess the effect of curcumin and curcumin loaded mesoporous silica nanoparticles (MSNs) against doxorubicin (DOX)-induced myocardial toxicity in rats. Furthermore, the study also included the bioavailability estimation of curcumin delivered alone and delivered via mesoporous technology. Cardiotoxicity was produced by cumulative administration of DOX (2.5 mg/kg for two weeks). Curcumin and curcumin loaded mesoporous nanoparticles (MSNs) each 200 mg/kg, po was administered as pretreatment for two weeks and then for two alternate weeks with DOX. The repeated administration of DOX induced cardiomyopathy associated with an antioxidant deficit and increased level of cardiotoxic biomarkers. Pretreatment with curcumin (alone and via MSNs) significantly protected myocardium from the toxic effects of DOX by significantly decreased the elevated level of malondialdehyde and increased the reduced level of reduced glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) in cardiac tissue. MSNs based delivery was found superior compared to curcumin delivered alone. Moreover, the results of bioavailability assessment in rats clearly indicated higher Cmax and AUC values in rats when curcumin was administered via MSNs indicating superior bioavailability. The bioavailability of curcumin loaded MSNs, biochemical and histopathology reports support the good cardioprotective effect of curcumin which could be attributed to its increased bioavaibility lead to good antioxidant and anti-inflammatory activity.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most common liver cancer worldwide, with poor prognosis and resistance to chemotherapy. This gives novel cancer treatment methods an overwhelming significance. Natural products offer great resources of developing new and effective chemopreventive or chemotherapeutic agents. Artocarpus communis extracts and its active constituent, prenylated flavonoid artocarpin induce human hepatocellular carcinoma cell death. However, the poor water solubility drawbacks of artocarpin restrict its clinical application and bioavailability. PURPOSE This study developed the artocarpin nanoparticle system to overcome the poor water solubility drawbacks and investigated the improvement of therapeutic efficacy of artocarpin by adopting novel nanoparticle delivery strategy. METHODS Antiproliferative activity of artocarpin was evaluated by MTT assay. Cell morphology observation by microscope, DNA fragmentation assay, cell cycle analysis, Annexin V apoptosis cell staining, monodansylcadaverine and acridine orange staining and immunoblot analysis were used to evaluate the induction of autophagy by artocarpin. The determination of particle size, amorphous transformation, hydrogen-bond formation, yield, encapsulation efficiency and the solubility study were used to investigate the solubility enhancement mechanism of artocarpin. RESULTS The present study demonstrates that the anticancer effect of artocarpin in HepG2 and PLC/PRF/5 hepatoma cells is mediated through the autophagic cell death mechanism. Results also demonstrated that artocarpin nanoparticles enhanced the solubility of artocarpin by reducing particle size, transforming high energy amorphous state, and forming hydrogen bond with excipients. Additionally, ArtN exhibited better autophagic cytotoxicity compared to free artocarpin. CONCLUSION This work reveals the antihepatoma activity of artocarpin by inducing autophagic cell death and the improvement of therapeutic efficacy of artocarpin by adopting novel nanoparticle delivery strategy. The research provided a basis of ArtN could be explored as a low-dose alternative of artocarpin in anticancer treatment and research applications.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Bupleurum chinense is a traditional Chinese medicinal herb which has been used to treat various inflammatory and infectious diseases, while Bupleurum kaoi is an endemic plant in Taiwan. We determined whether B. chinense and B. kaoi and their biologically active saikosaponin compounds possess anti-melanoma activity. In addition, we developed a novel saikosaponin-d nanoparticle system to improve its solubility, and evaluated its antiproliferative effects and molecular mechanisms in melanoma cells. MATERIALS AND METHODS Ethanolic extracts from B. chinense and B. kaoi were prepared, and their saikosaponin contents were determined by high performance liquid chromatography analysis. Saikosaponin-d nanoparticles were synthesized, and their physicochemical properties were evaluated by particle size analyzer, transmission electron microscopy, differential scanning calorimetry, X-ray diffractometry, and Fourier transform infrared spectroscopy. Human A375.S2 melanoma cells were cultured, and cell viability determined by the MTT assay. Apoptosis was evaluated by determination of mitochondrial membrane potential, and signal transduction pathways investigated by Western blotting. RESULTS Ethanolic extracts from B. kaoi showed more potent antiproliferative effect on human A375.S2 melanoma cells compared to B. chinense. The saikosaponin-a, -c and -d contents were higher in B. kaoi compared to B. chinense. Saikosaponin-d was the most potent compound in terms of anti-melanoma activity, and saikosaponin-d nanoparticles exhibited increased water solubility due to lowered particle size, amorphous transformation and intermolecular hydrogen bond formation with the excipient. Furthermore, saikosaponin-d nanoparticles showed enhanced antiproliferative activity against melanoma cells, and induced apoptosis through the mitochondrial pathway. The anti-melanoma activity was mediated by phosphorylation of JNK and p38, phosphorylation of p53, increased level of cytochrome c, and activation of caspase 9. CONCLUSIONS B. kaoi contains higher saikosaponin content and shows greater anti-melanoma activity than B. chinense. Saikosaponin-d nanoparticles have improved solubility, and may have potential use in the future as a form of treatment for melanoma.

Abstract
CONTEXT The physicochemical properties of drugs such as partition coefficient play a major role in the development of lipid-based drug delivery systems. The major obstacle lies in encapsulation of a drug with low partition coefficient into these systems. OBJECTIVE The objective of this study was to design and optimize a novel lipid-based delivery system with higher loading, improved pharmacokinetics consequently enhancing the oral bioavailability of drugs with low partition coefficient like valsartan. MATERIALS AND METHODS The optimized formulation consists of Capryol 90, Cremophor RH 40, and Transcutol HP. Pseudo ternary phase diagrams were used to optimize the components and their concentrations in the formulation. Dissolution studies of the selected formulations were compared with plain drug and marketed product at three pH conditions (pH 1.2, 4.5 and 6.8). Pharmacokinetic parameters of optimized formulations were determined in Wistar rats and compared with that of plain drug. RESULTS AND DISCUSSION The optimized formulation with a mean particle size of 50 nm showed significant improvement (p < 0.05) in dissolution rate with pH independence compared to plain drug and marketed product. The in vivo studies in Wistar rats revealed about 2.30- and 1.68-fold increase in the oral bioavailability and Cmax of valsartan from lipid-based formulation compared to plain drug. CONCLUSION The engineered formulation strategy by type IV lipid-based formulations can be successfully exploited to improve the dissolution rate and oral deliverability of drugs like valsartan.

Abstract
Complexes of diclofenac sodium (DF-Na) with hydroxypropyl betacyclodextrin (HPβCD) were prepared by co-evaporation in a 1:1 ratio and characterized in light of previously reported data. Phase solubility diagrams were obtained for DF-Na with HPβCD in the presence and absence of zinc ions. Dissolution profiles were obtained for DF-Na and its HPβCD complex at acidic (pH 1.2) as well as in phosphate buffer (pH 6.8), in the presence and absence of zinc. HPβCD, as expected, was shown to improve the dissolution of DF-Na in acidic medium but not in phosphate buffer (pH 6.8). The presence of zinc ions decreased the in vitro dissolution of DF-HPβCD complex in acidic medium (pH 1.2) but not in phosphate buffer (pH 6.8). It was confirmed that the precipitate that was formed by zinc ions in the presence of HPβCD and DF-Na contained no cyclodextrin and most likely it was a mixture of the complexes: DF2-Zn and DF-Zn with some molecules of water. In vivo experiments on rats have shown that HPβCD has no statistically significant effect on absorption or bioavailability of DF-Na in spite of the observed improvement of its in vitro dissolution by HPβCD. Moreover, zinc ions were shown to decrease the absorption rate of DF-Na in rats model but did neither significantly alter the absorption nor bioavailability of DF-HPβCD complex. The zinc induced precipitates of DF were shown to have significantly different crystalline properties when HPβCD was present. Therefore, the pharmaceutical details of a DF-Na preparation should be considered when designing the formulation and predicting possible interaction between DF-Na (or other potential NSAIDs) and zinc metal.

Abstract
Since the introduction of gliclazide in the pharmaceutical industry, a large number of research groups have been engaged in various investigations aiming to enhance its biomedical application. But, very limited efforts have been made to study polymorphism of gliclazide. Therefore, this study focuses on solvent-induced polymorphism of gliclazide and its characterization by thermal methods. Three polymorphs namely, Form-I, II and III and an amorphous powder were produced from different solvents and solvent mixtures. Crystals were analyzed using infrared spectroscopy, differential scanning calorimetry, X-ray powder diffraction and single crystal x-ray diffraction. Polymorph Form-I is found to exist in centro-symmetric triclinic P-1 space group and has endothermic peak at 162.93°. Form-II has endothermic peak from 171.2° to 172.35° and exists in centro-symmetric monoclinic P21/a space group while Form-III has endothermic peak from 168.93° to 169.86° and exists in centro-symmetric monoclinic P21/n space group. The equilibrium solubility values of Form-I, II, III and the amorphous form were 0.4825±0.025, 0.2341±0.042, 0.2581±0.038 and 0.5213±0.072 mg/ml, respectively. The Form-I has relatively higher solubility and similar to that of amorphous gliclazide. Form-II and Form-III are relatively most stable and least soluble. However, there was no remarkable difference in their aqueous solubility under the conditions in which study was conducted.

Abstract
Particle size reduction can be used for enhancing the dissolution of poorly water-soluble drugs in order to enhance bioavailability. In nanosuspensions, the particle size of the drug is reduced to nanometer size. Nanosuspensions after downstream processing into drug products have successfully shown its impact on formulation design, the augmentation of product life cycle, patent life, and therapeutic efficacy. Formulation considerations for the nanosuspension formulation, its processing into a solid form, and aspects of material characterization are discussed. Technology assessments and feasibility of upstream processes for nanoparticle creation, and subsequently transformation into a drug product via the downstream processes have been reviewed. This paper aims to bridge formulation and process considerations along with patent reviews and may provide further insight into understanding the science and the white space. An analysis of current patent outlook and future trends is described to fully understand the limitations and opportunities in intellectual property generation.

Abstract
Solid dispersion (SD) technique is a promising strategy to improve the solubility and dissolution of BCS class II drugs. However, only few products are marketed till today based on SD technology due to poor flow properties and stability. The present work was intended to solve these problems by using combination approach, melt dispersion and surface adsorption technologies. The main aim of the present work is to improve the absorption in the stomach (at lower pH) where the absorption window exists for the drug by improving the dissolution, resulting in the enhancement of oral bioavailability of poorly soluble, weakly acidic drug with pH dependant solubility, i.e. valsartan. Melt dispersion granules were prepared in different ratios using different carriers (Gelucire 50/13, PEG 8000 and Pluronic F-68) and lactose as an adsorbent. Similarly, physical mixtures were also prepared at corresponding ratios. The prepared dispersion granules and physical mixtures were characterized by FTIR, DSC and in vitro dissolution studies. DSC studies revealed reduction in the crystallinity with a possibility of presence of amorphous character of drug in the dispersion granules. From dissolution studies, valsartan Gelucire dispersion (GSD4; 1:4 ratio) showed complete drug release in 30 min against the plain drug which showed only 11.31% of drug release in 30 min. Pharmacokinetic studies of optimized formulation in male Wistar rats showed 2.65-fold higher bioavailability and 1.47-fold higher Cmax compared to pure drug. The melt dispersion technology has the potential to improve dissolution and the bioavailability of BCS class II drugs.

Abstract
OBJECTIVE Preparation of magnolol-loaded amorphous solid dispersion was investigated for improving the bioavailability. MATERIALS AND METHODS A solid dispersion of magnolol was prepared with polyvinylpyrrolidone K-30 (PVP) by melting method, and the physical properties were characterized by using differential scanning calorimetry, powder X-ray diffractometry, Fourier transformation-infrared spectroscopy and scanning electron microscope. In addition, dissolution test was also performed. Subsequently, the bioavailability of magnolol pure compound, its physical mixture and solid dispersion were compared in rabbits. The blood samples withdrawn via marginal ear vein at specific time points were assayed by HPLC method. RESULTS Oral administration of the solid dispersion of magnolol with PVP significantly increased the systemic exposures of magnolol and magnolol sulfates/glucuronides by 80.1% and 142.8%, respectively, compared to those given with magnolol pure compound. CONCLUSION Magnolol-loaded amorphous solid dispersion with PVP has demonstrated enhanced bioavailability of magnolol in rabbits.

Abstract
Lutein, the primary carotenoid present in the central area of the retina of eye appears to be associated with the protection against age-related macular degeneration (the leading cause of blindness in older adults). Its lipophilicity and consequently its scarce water solubility (1.3×10(-9)M) represent a drawback for bioavailability. To circumvent these unfavorable characteristics, in this work lutein (Lut) have been encapsulated in amphiphilic cyclodextrin (ACyD) by following the well-established strategy of entrapping a lipophilic drug in CyD carriers. Primary face butyrate modified β-cyclodextrins (C(4:7)) form in water nanoaggregates with a average size of 250nm and a ζ-potential of about -6mV. They are able to entrap lutein at 1:6 Lut/ACyD molar ratio by yielding nanoassemblies of vesicular aspect (320nm and -8mV) such as observed by static, dynamic and electrophoretic light-scattering. UV-vis measurements revealed that electronic properties of lutein were maintained when interact with ACyD nanoaggregates. The monitoring of the entapped carotenoid leaking from ACyD nanostructures was investigated suggesting the potential of Lut/ACyD nanoassemblies in drug delivery.

Abstract
Resveratrol (RES), a well-known antioxidant and anti-inflammatory compound, is abundant in red wine and exerts numerous pharmacological effects, including hepatoprotection and cadioprotection. Unfortunately, RES is restricted in clinical application due to poor dissolution property and adsorption. In addition, red wine as a supplement for preventing disease is not recommended for patients with alcohol-related disorders. To address these limitations, we successfully developed a novel RES nanoparticle system (RESN) and demonstrated that RESN could circumvent the physicochemical drawbacks of raw RES with respect to dissolution, such as the reduction of particle size, amorphous transformation, and hydrogen-bond formation. In addition, we employed an animal model of CCl₄-induced hepatotoxicity to estimate the potential of the nanoparticle formulation to improve the hepatoprotective effect of orally administered RES. Our results demonstrated that RESN can diminish liver function markers (aspartate aminotransferase and alanine aminotransferase) by decreasing hepatocyte death due to CCl₄-induced hepatotoxicity in rats, when compared with RES administration. The effect was achieved by reducing oxidative stress (decreased reactive oxygen species and lipid peroxidation) and lowering inflammatory cytokines (decreased tumor necrosis factor-α and interleukin 1β) and protein expression (cyclooxygenase-2, inducible nitric oxide synthase, cytosolic phospholipase A2, and caspase-3). In conclusion, enhancement of the dissolution of RES through a nanoparticle engineering process can result in increased hepatoprotective effects mediated by antioxidant and anti-inflammatory activities. Consequently, we suggest that RESN deserves further study, perhaps in prophylaxis of chronic liver diseases.

Abstract
Kaempferol (KAE) is a strong antioxidant flavonoid compound, but its clinical application is limited by quantity and poor dissolution property. However, the dissolution mechanism of a kaempferol nanoparticle formulation (KAEN) has not yet been elucidated. The aim of the present study was therefore to use a nanoparticle engineering process to resolve the dissolution problem. Our data indicated that KAEN effectively increased the dissolution percentage by particle size reduction, high encapsulation efficiency, amorphous transformation, and hydrogen-bond formation with excipients. In addition, we used several different antioxidant activity assays to evaluate KAE and KAEN. The data indicated that KAEN retained potent antioxidant activity after the nanoparticle engineering process and showed better antioxidant activity than KAE dissolved in water (P < 0.05). According to these findings, we concluded that KAEN could be a low-dose alternative to KAE in health food and future clinical research.

Abstract
The objective of the present study was to elucidate the mechanisms of intestinal transport of bis(12)-hupyridone (B12H) to predict its oral bioavailability. The effect of the B12H concentration and the contribution of the drug efflux transporters, P-glycoprotein (P-gp or ABCB1) and multidrug resistance-associated proteins (MRPs or ABCC) on B12H absorption were measured and evaluated using the human intestinal epithelial Caco-2 cell monolayer in the presence of transporter inhibitors. The results indicated that B12H was absorbed in a dose-dependent manner at concentrations ranging from 132 to 264 µM. However, only apical efflux was observed in the directional transport studies for B12H below 88 µM (P(app) (AP-to-BL): virtually zero; P(app) (BL-to-AP): 1.591 ± 0.071 × 10(-5) cm s(-1) ). P-gp and mixed P-gp/MRP inhibitors significantly increased the absorptive transport (P(app) (AP-to-BL)) to 0.619 ± 0.018 × 10(-5) and 0.608 ± 0.025 × 10(-5) cm s(-1) , respectively, while decreasing secretory transport (P(app) (BL-to-AP)) by >75%. A multiple-MRP inhibitor, probenecid, increased the P(app) (AP-to-BL) to 0.329 ± 0.015 × 10(-5) cm s(-1) while decreasing the P(app) (BL-to-AP) by 50%. Another multiple-MRP inhibitor, indomethacin, only modestly decreased the P(app) (BL-to-AP) by ∼30% and had no effect on the absorptive transport (P(app) (AP-to-BL): virtually zero). In addition, the effect of various pharmaceutical excipients (e.g. Pluronic F-68, Tween-80 and Brij-35) on B12H transport was determined and compared. Among them, Brij-35 effectively enhanced B12H absorption at a concentration lower than its critical micelle concentration (CMC, 60 µM). Therefore, Brij-35 can be used as a potential enhancer to improve intestinal absorption of B12H for oral administration.

Polímeros naturais, naturais modificados e sintéticos são empregados como excipientes farmacêuticos para a formulação de cosméticos e medicamentos de liberação convencional e de liberação modificada. Nos dias atuais, polímeros são desenvolvidos para atuarem como moduladores e direcionadores da liberação de fármacos em sítios específicos no organismo. Polímeros biodegradáveis, bioadesivos, biomiméticos e hidrogéis responsivos têm sido amplamente incluídos em formulações farmacêuticas. Os avanços na idealização de novos Sistemas de Liberação de Fármacos somente são e serão permitidos a partir do desenvolvimento de polímeros projetados especificamente para a área farmacêutica. Neste sentido, o presente artigo visa a revisar e apresentar informações sobre o uso de polímeros em aplicações farmacêuticas que poderão ser úteis no planejamento de novos sistemas com desempenhos superiores.

Abstract
The purpose of this study was to develope and characterize a micellar formulations of N-{[(2-hydroxy-5- nitrophenyl)amino]carbonothioyl}-3,5-dimethylbenzamide (DM-PIT-1)-a new small molecule non-lipid antagonist of phopshotidylinositol-3.4.5-triphopshate and inhibitor of the PI3-kinase pathway. Micelle-forming PEG(2000)-PE was used to solubilize DM-PIT-1. To improve the specificity of the micellar DM-PIT-1, cancer-targeting anti-nucleosomal mAb2C5 antibodies as well as Tumor necrosis factor- Related Apoptosis-Inducing Ligand (TRAIL) were attached to the surface of polymeric micelles. DM-PIT-1 was effectively incorporated (> 70%) into 14-16 nm micelles, which had a negative surface zeta potential of 4-5 mV. Micellar DM-PIT-1 demonstrated high in vitro cytotoxicity against various cancer cells. An improved potency of the dual-activity DM-PIT-1/TRAIL combination nanoparticles in inducing death of TRAIL-resistant cancer cells was shown. Efficacy of the TRAIL therapy was enhanced by combining it with the 2C5 antibody cancer-targeted micellar form of DM-PIT-1. In conclusion, DM-PIT-1 micellar preparations can be used for targeted combination therapy against TRAIL-resistant cancers.

Abstract
We have taken kinetic measurements of the hydrolytic degradation of cefixime, and have studied the effect of Captisol complexation and water-soluble polymers on that degradation. The phase solubility of cefixime in Captisol was determined. Kinetic measurements were carried out as a function of pH and temperature. High-performance liquid chromatography (HPLC) was performed to assay all the samples of phase-solubility analysis and kinetic measurements. Chromatographic separation of the degradation products was also performed by HPLC. FT-IR spectroscopy was used to investigate the presence of any interaction between cefixime and Captisol and soluble polymer. The phase-solubility study showed A(L)-type behaviour. The pH-rate profile of cefixime exhibited a U-shaped profile whilst the degradation of cefixime alone was markedly accelerated with elevated temperature. A strong stabilizing influence of the cefixime-Captisol complexation and hypromellose was observed against aqueous mediated degradation, as compared with povidone and macrogol. The unfavourable effect of povidone and macrogol may have been due to the steric hindrance, which prevented the guest molecule from entering the cyclodextrin cavity, whereas hypromellose did not produce any steric hindrance.
