Abstract
Voriconazole (VCZ) is a well-known broad spectrum triazole antifungal, mainly used orally and intravenously. The study aimed to formulate VCZ into ultradeformable elastosomes for the topical treatment of ocular fungal keratitis. Different formulae were prepared using a modified ethanol injection method, employing a 33 Box-Behnken design. They were characterized by measuring their entrapment efficiency (EE%), particle size (PS), polydispersity index (PDI) and zeta potential (ZP). The optimized formula was subjected to further in vitro investigations and in vivo evaluation studies. The prepared vesicles had satisfactory EE%, PS, PDI and ZP values. The numerical optimization process suggested an optimal elastosomal formula (OE) composed of phosphatidyl choline and brij S100 at the weight ratio of 3.62: 1, 0.25%w/v hyaluronic acid and 5% (percentage from phosphatidyl choline/brij mixture) polyvinyl alcohol. It had high EE (72.6%), acceptable PS and PDI (362.4 nm and 0.25, respectively) and highly negative ZP of −41.7 mV. OE exhibited higher elasticity than conventional liposomes, with acceptable stability for three months. Transmission electron microscopy demonstrated the spherical morphology of vesicles with an external transparent coat of Hyaluronic acid. OE was expected to cause no ocular irritation or blurring in vision as reflected by pH and refractive index measurements. The histopathological study revealed the safety of OE for ocular use. The fungal susceptibility testing using Candida albicans demonstrated the superiority of OE to VCZ suspension, with greater and more durable growth inhibition. Therefore, OE can be regarded as a promising formula, achieving both safety and efficacy.

Abstract
Oleogel consists of hydrophobic solvent and an oleogelator. In this study, attempts were made to study the influence of Celecoxib solubility, concentration and dispersability on its release, absorption, and biological performance. Oleogels were prepared to study the formulation variables on its stability and release. Castor oil was selected as the oil and the oleogelator concentration was 4.5% w/w. F3 revealed the highest release and stability compared to other formulae. The percent permeated across the rat intestine showed a 7.5-fold increase over free Celecoxib, and its lifetime was found to be greater than 18 months. The efficacy of free Celecoxib and oleogel formulae to treat rats with ulcerative colitis was done via the induction of ulcerative colitis (UC) through administration of 5% dextran sodium sulphate (DSS). Celecoxib besides its formulae significantly reduced the release of Leucine rich 2 glycoprotein (LRG), Myeloperoxidase (MPO), Tumor necrosis factor-α (TNF-α), proinflammatory cytokine expression, High mobility group box 1 (HMGB1), Nuclear factor kappa B (NF-ΚB), Trefoil Factor 3 (TFF3), Metalloproteinase-3 (MMP3), and miRNA31. Moreover, F3 significantly increased the colonic cAMP in DSS treated rats and reduced the intestinal inflammation beside healing of mucosa and restitution of the epithelium of the gastrointestinal tract.

Abstract
Cilostazole (CLZ) is an anti-platelet drug that suffers from extensive first pass-metabolism and gastrointestinal side effects. This study aimed to prepare spanlastics for enhancing the transdermal delivery of CLZ to avoid its oral problems. CLZ-loaded spanlastic dispersions were prepared by ethanol injection technique according to a 413121 full factorial design to investigate the effect of formulation variables on entrapment efficiency (EE%), particle size (PS), zeta potential (ZP), and the percent of drug released after 2 and 24 h (Q2 and 24 h). Spanlastic-loaded gel of the optimized formula was prepared using hydroxypropyl methylcellulose (HPMC K4M). The optimum formula (F13), constitutes of Span60 and CremophoreRH40 at a weight ratio of 80:20 and distilled water for hydration, had the highest desirability value of (0.841) and exhibited the highest EE% of (69.29 ± 0.29%), PS of (452.7 ± 5.94 nm), ZP of (-32.6 ± 0.4 mV), Q 2 h of (33.28 ± 1.45%) and Q24h of (82.37 ± 1.37. F13 was subjected to ex-vivo permeation study and showed a cumulative amount permeated after 48 h(Q48h) equal to (750.71 ± 3 μg/cm2) in comparison to the drug suspension which showed Q48h equal to (190.20 ± 6.3 μg/cm2). Also, F13 showed an increase in the drug flux of (17.84 μg/cm2.h) and enhancement ratio(ER) of (5.71 ± 0.1) in comparison to the drug suspension that showed drug flux of (3.12 ± 0.0 μg/cm2.h). Spanlastics-loaded gel was subjected to an in-vitro release study compared to(F13) spanlastic dispersion and showed a more sustained release effect. In addition, histopathological studies showed no sign of skin alteration confirming safe delivery through the skin. CLZ showed promising results with high potential to be delivered transdermally.

Abstract
The use of nano- and microparticles as a release system for agrochemicals has been increasing in agricultural sector. However, the production of eco-friendly and smart carriers that can be easily handled in the environment is still a challenge for this technology. In this context, we have developed a biodegradable release system for the herbicide atrazine with magnetic properties. Herein, we investigated the (a) physicochemical properties of the atrazine-loaded magnetic poly(ε-caprolactone) microparticles (MPs:ATZ), (b) in vitro release kinetic profile of the herbicide, and (c) phytotoxicity toward photosynthesis in the aquatic fern Azolla caroliniana. The encapsulation efficiency of the herbicide in the MPs:ATZ was ca. 69%, yielding spherical microparticles with a diameter of ca. 100 μm, a sustained-release profile, and easily manipulated with an external magnetic field. Also, phytotoxicity issues showed that the MPs:ATZ maintained their herbicidal activity via inhibition of PSII, showing lower toxicity compared with the nonencapsulated ATZ at 0.01 and 0.02 μmol·L-1. Therefore, this technology may conveniently promote a novel magnetic controlled release of the herbicide ATZ (with the potential to be collected from a watercourse) and act as a nutrient boost to the nontarget plant, with good herbicidal activity and reduced risk to the environment.

Abstract
Three-dimensional (3D) printing application is a promising method for bone tissue engineering. For enhanced bone tissue regeneration, it is essential to have printable composite materials with appealing properties such as construct porous, mechanical strength, thermal properties, controlled degradation rates, and the presence of bioactive materials. In this study, polycaprolactone (PCL), gelatin (GEL), bacterial cellulose (BC), and different hydroxyapatite (HA) concentrations were used to fabricate a novel PCL/GEL/BC/HA composite scaffold using 3D printing method for bone tissue engineering applications. Pore structure, mechanical, thermal, and chemical analyses were evaluated. 3D scaffolds with an ideal pore size (~300 µm) for use in bone tissue engineering were generated. The addition of both bacterial cellulose (BC) and hydroxyapatite (HA) into PCL/GEL scaffold increased cell proliferation and attachment. PCL/GEL/BC/HA composite scaffolds provide a potential for bone tissue engineering applications.

Abstract
Osteoarthritis (OA), the most common form of arthritis, is characterized by chronic inflammation, degeneration of articular cartilage and whole joints. Local delivery by intra-articular (IA) injection of small molecules is an established treatment to relieve pain and improve joint motion, requiring month-lasting release of therapeutic drug doses. We incorporated anti-inflammatory drug celecoxib in poly (D, L-lactic acid) microparticles using two spray-drying approaches - either as a solid drug solution or embedded as milled nano drug. Differential scanning calorimetry, X-ray powder diffraction, electron microscopy and in vitro drug release allowed comparison of the microparticles. Both types resulted in spherical particles ranging from 20 to 40 μm mean size, with high drug loadings (10% to 50% w/w) and entrapment efficiencies > 80%. However, after 90 days, in vitro celecoxib release from nano drug embedded microparticles presented a significantly slower release in comparison to drug in solution microparticles, attributed to the presence of stabilized amorphous drug. No cytotoxicity was observed in human articular synoviocytes and PGE2 release was fully suppressed at low doses of both microparticulate systems. This study provides techniques to release high drug loads over months in a tunable manner, providing valuable options for the IA management of osteoarthritis.

Abstract
Eudragit® polymer has been widely used in film-coating for enhancing the quality of products over other materials (e.g., shellac or sugar). Eudragit® polymers are obtained synthetically from the esters of acrylic and methacrylic acid. For the last few years, they have shown immense potential in the formulations of conventional, pH-triggered, and novel drug delivery systems for incorporating a vast range of therapeutics including proteins, vitamins, hormones, vaccines, and genes. Different grades of Eudragit® have been used for designing and delivery of therapeutics at a specific site via the oral route, for instance, in stomach-specific delivery, intestinal delivery, colon-specific delivery, mucosal delivery. Further, these polymers have also shown their great aptitude in topical and ophthalmic delivery. Moreover, available literature evidences the promises of distinct Eudragit® polymers for efficient targeting of incorporated drugs to the site of interest. This review summarizes some potential researches that are being conducted by eminent scientists utilizing the distinct grades of Eudragit® polymers for efficient delivery of therapeutics at various sites of interest.

Abstract
The most enthralling and versatile class of drugs called the Non-steroidal anti-inflammatory (NSAIDs) showed its therapeutic utility in inflammation, beginning from the era of classic drug 'Aspirin'. NSAIDs and their well-established action based on inhibiting the COX-1 and COX-2 enzyme leads to blockage of prostaglandin pathway. They further categorized into first generation (non-selective inhibitor) and second generation (selective COX-2 inhibitors). Selective COX-2 inhibitors has advantage over non-selective in terms of their improved safety profile of gastro-intestinal tract. Rejuvenating and recent avenues for COXIBS (selective COX-2 inhibitors) explains its integrated role in identification of biochemical pain signaling as well as its pivotal key role in cancer chemotherapy. A key role player in this class is the Celecoxib (only FDA approved COXIB) a member of Biopharmaceutical classification system (BCS) II. Low solubility and bioavailability issues related with celecoxib lead to the development and advancement in the discovery and research of some possible formulation administered either orally, topically or via transdermal route. This review article intent to draw the bead on Celecoxib and it clearly explain extensive knowledge of its disposition profile, its dynamic role in cancer at cellular level and cardiovascular risk assessment. Some of the possible formulations approaches with celecoxib and its improvement aspects are also briefly discussed.

Abstract
Background:
Bioavailability, one of the prime pharmacokinetic properties of a drug, is defined as the
fraction of an administered dose of unchanged drug that reaches the systemic circulation and is used to describe
the systemic availability of a drug. Bioavailability assessment is imperative in order to demonstrate whether the
drug attains the desirable systemic exposure for effective therapy. In recent years, bioavailability has become
the subject of importance in drug discovery and development studies.
Methods:
A systematic literature review in the field of bioavailability and the approaches towards its enhancement
have been comprehensively done, purely focusing upon recent papers. The data mining was performed
using databases like PubMed, Science Direct and general Google searches and the collected data was exhaustively
studied and summarized in a generalized manner.
Results:
The main prospect of this review was to generate a comprehensive one-stop summary of the numerous
available approaches and their pharmaceutical applications in improving the stability concerns, physicochemical
and mechanical properties of the poorly water-soluble drugs which directly or indirectly augment their bioavailability.
Conclusion:
The use of novel methods, including but not limited to, nano-based formulations, bio-enhancers,
solid dispersions, lipid-and polymer-based formulations which provide a wide range of applications not only
increases the solubility and permeability of the poorly bioavailable drugs but also improves their stability, and
targeting efficacy. Although, these methods have drastically changed the pharmaceutical industry demand for the
newer potential methods with better outcomes in the field of pharmaceutical science to formulate various dosage
forms with adequate systemic availability and improved patient compliance, further research is required.

Fahmy AM, El-Setouhy DA, Habib BA, Tayel SA. Enhancement of Transdermal Delivery of Haloperidol via Spanlastic Dispersions: Entrapment Efficiency vs. Particle Size. AAPS PharmSciTech 2019; 20:95. [PMID: 30694404 DOI: 10.1208/s12249-019-1306-2] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2018] [Accepted: 01/08/2019] [Indexed: 01/23/2023] Open
Abstract
Haloperidol (Hal) is a well-known typical antipsychotic. Hepatic first pass metabolism leads to its limited oral bioavailability. This study aimed at enhancing transdermal delivery of Hal via spanlastic formulae. Hal-loaded spanlastics of Span®60 and an edge activator (EA) were successfully prepared by ethanol injection method according to a 31.41 full factorial design. In this design, independent variables were X1, EA type, and X2, Span®60 to EA ratio. Y1, percentage entrapment efficiency (EE%); Y2, particle size (PS); Y3, deformability index (DI); and Y4, percentage drug released after 4h (Q4h), were chosen as dependent variables. The Fourier-transform infrared spectral analysis showed no considerable chemical interaction between Hal and the used excipients. Both factors affected significantly all the responses except DI. Desirability of each prepared formula was calculated based on maximizing EE% and Q4h and minimizing PS. Formula F6, with X1, Tween®80, and X2, 8:2, had the highest desirability value followed by F7, with X1, Tween®80, and X2, 6:4, and both were chosen as selected formulae (SF) for further investigation. F6 (having more entrapped Hal), F7 (of smaller PS), and Hal solution in propylene glycol were subjected to ex vivo permeation test through newborn rat skin. Both formulae showed marked enhancement in drug permeation compared with drug solution. The significantly higher Q36h and J36h of F7 from F6 may indicate that the smaller particle size aided more than higher entrapment in achieving a higher permeation for Hal of 3.5±0.2μg/cm2.h. These results are promising for further investigation of this formula.

Abstract
Inflammatory bowel disease (IBD) is a common disease characterized by chronic inflammation in gastrointestinal tracts, which is primarily treated by administering anti-inflammatory and immunosuppressive drugs that inhibit the burden of intestinal inflammation and improve disease-related symptoms. However, the established therapeutic strategy has limited therapeutic efficacy and adverse drug reactions. Therefore, new disease-targeting drug-delivery strategies to develop more effective treatments are urgent. This review provides an overview of the drug-targeting strategies that can be used to treat IBD, and our recent attempts on the colon-specific delivery system (Pae-SME-CSC) with a paeonol-loaded self-microemulsion (Pae-SMEDDS) are introduced.

Abstract
PURPOSE Epilepsy is a prevalent neurological disorder with a high frequency of drug resistance. While significant advancements have been made in drug delivery systems to overcome anti-epileptic drug resistance, efficacies of materials in biological systems have been poorly studied. The purpose of the study was to evaluate the anti-epileptic effects of injectable poly(epsilon-caprolactone) (PCL) microspheres for controlled release of an anticonvulsant, phenytoin (PHT), in an animal model of epilepsy. METHODS PHT-PCL and Blank-PCL microspheres formulated using an oil-in-water (O/W) emulsion solvent evaporation method were evaluated for particle size, encapsulation efficiency, surface morphology and in-vitro drug release profile. Microspheres with the most suitable morphology and release characteristics weresubsequently injected into the hippocampus of a rat tetanus toxin model of temporal lobe epilepsy. Electrocorticography (ECoG)from the cerebral cortex were recorded for all animals. The number of seizure events, severity of seizures, and seizure duration were then compared between the two treatment groups. RESULTS We have shown that small injections of drug-loaded microspheres are biologically tolerated and released PHT can control seizures for the expected period of time that is in accord with in-vitro release data. CONCLUSION The study demonstrated the feasibility of polymer-based delivery systems incontrolling focal seizures.

Abstract
In this work alginate and alginate-chitosan beads containing celecoxib solubilized into a self-emulsifying phase were developed in order to obtain a drug delivery system for oral administration, able to delay the drug release in acidic environment and to promote it in the intestinal compartment. The rationale of this work was linked to the desire to improve celecoxib therapeutic effectiveness reducing its gastric adverse effects and to favor its use in the prophylaxis of colon cancer and as adjuvant in the therapy of familial polyposis. The systems were prepared by ionotropic gelation using needles with different diameters (400 and 600 μm). Morphology, particle size, swelling behavior, and in vitro drug release performance of the beads in aqueous media with different pH were investigated. The experimental results demonstrated that the presence of chitosan in the formulation caused an increase of the mechanical resistance of the bead structure and, as a consequence, a limitation of the bead swelling ability and a decrease of the drug release rate at neutral pH. Alginate-chitosan beads could be a good tool to guarantee a celecoxib colon delivery.

Abstract
5-Fluorouracil (5-FU) is one among the anti-cancer agents in FOLFORINOX treatment along with oxaliplatin and irinotecan for the treatment of colorectal cancer. Despite its potential activity on the tumor cells, it lacks site specificity partly attributed by its biodistribution to healthy cells resulting in toxic effects to healthy cells. Therefore, we have formulated 5-fluorouracil enteric-coated nanoparticles (5-FUEC) to localize the drug in the colon area that enables its prolonged presence in target area in a sustained manner. The current work emphasizes on enhanced anti-cancer activity of 5-FUEC sequencing its apoptotic activity on HCT 116 colorectal cancer cell lines in vitro. MTT assay exhibited 5.5-fold decrease in IC50 value of nanoparticles comparable to 5-FU. Nuclear fragmentation with irregular edges in nucleus of cells justified its improved activity. Furthermore, flow cytometric analysis confirms the majority of cells gated in early apoptotic (39.75%) and late apoptotic phase (36.25%). Acridine orange/ethidium bromide staining (AO/EB) exhibited cells with red fluorescence (indicating apoptosis) comparable to the control and 5-FU. γ-Scintigraphic studies determined the applicability and feasibility of the enteric coating with mean gastric emptying time, mean intestinal transit time and mean colon arrival time of 1.89 ± 0.03, 2.15 ± 0.05 and 4.03 ± 0.27 h, respectively. Moreover, nanoparticulate approach was found significant in reducing tumor size and volume in xenograft tumor models in vivo along with sustained release. These superior anti-cancer activities exhibited by 5-FUEC indicated that it could be a potential alternative to chemotherapy for colorectal cancer.

Abstract
Colorectal cancer (CRC) is the third most common cancer and the fourth leading cause of cancer death in the world. Currently available chemotherapy of CRC usually delivers the drug to both normal as well as cancerous tissues, thus leading to numerous undesirable effects. Much emphasis is being laid on the development of effective drug delivery systems for achieving selective delivery of the active moiety at the anticipated site of action with minimized unwanted side effects. Researchers have employed various techniques (dependent on pH, time, pressure and/or bacteria) for targeting drugs directly to the colonic region. On the other hand, systemic drug delivery strategies to specific molecular targets (such as FGFR, EGFR, CD44, EpCAM, CA IX, PPARγ and COX-2) overexpressed by cancerous cells have also been shown to be effective. This review aims to put forth an overview of drug delivery technologies that have been, and may be developed, for the treatment of CRC.

Abstract
PURPOSE Microspheres of chitosan (CS) cross-linked with polyethylene glycol (PEG) were prepared by emulsion-cross-linking followed by the solvent evaporation technique. The formulations were characterized and subjected to in vitro and in vivo tests to assess cell growth, changes in cell morphology, and activities by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay on human HT-29 colon cancer cell-lines. METHODS In vivo activity was evaluated for dimethyl hydrazine-induced colorectal cancer in albino male Wistar rats. Biochemical and histological parameters were evaluated to understand their effectiveness for colon cancer therapy. RESULTS The 5-FU immediate release (IR) formulations suspended in SCMC produced an immediate cytotoxic effect, whereas microspheres inhibited proliferation of tumor cells to induce apoptosis over an extended time. Minimum inhibitory concentration (IC50) values for both standard plain 5-FU and 5-FU-loaded microspheres were respectively 5.00 ± 0.004 µg/mL and 165 ± 1.9 µg/mL which showed the improved safety profile of the microsphere formulation. Tissue distribution showed high concentration of 5-FU in colon that was higher than IC50 value required to stop the growth or death of colon cancer cells from the colonic dysplasia in Duke's stage A. Significant reduction in tumor volume and multiplicity was observed with increased levels of liver enzymes in animals when treated with standard 5-FU formulation compared with 5-FU loaded microspheres. Elevated levels of serum albumin, creatinine, leukocytopenia, and thrombocytopenia were observed in animals for the standard 5-FU formulation. CONCLUSION The PEG cross-linked CS microspheres of this study slowly released 5-FU up to 24 h to colonic region and enhanced the antitumor activity.

Abstract
Chlorambucil (CHL) is a water-insoluble antineoplastic drug having a short elimination half-life. It suffers from remarkable differences in pharmacokinetics following oral administration. The current work aimed to assess safety and pharmacokinetics of CHL-loaded, lipoprotein-mimic, nanoparticles (NPs) following intravenous administration. The design of NPs was based on complexation between egg yolk lecithin (EYL) and bovine serum albumin (BSA). The NPs were preliminary evaluated via FT-IR, DSC and P-XRD. The NPs were characterized for particle size, zeta potential, morphology and drug entrapment efficiency (EE%). The best achieved NP dispersion (LP6) and CHL solution were challenged for in vitro hemolytic potential, in vivo vascular irritation studies in rabbits and in vivo pharmacokinetics following intravenous administration in rats. The results confirmed that NPs were stabilized by hydrophobic-attractions and hydrogen-bondings between CHL, BSA and EYL. The amorphous dispersion of CHL within NPs was revealed. LP6 dispersion displayed monodispersed nano-spherical particles (144.33 ± 2.17 nm). It possessed the highest negative zeta potential (-30.55 ± 0.24 mV) and the largest EE% (86.35 ± 2.33%). The significantly (P < 0.05) prolonged MRT(0-∞), longer elimination t50% and reduced plasma clearance highlighted the long-circulating characteristics of LP6. The preliminary safety evaluations and the seven-fold increase in bioavailability elucidated potentiality for smart intravenous delivery of CHL.

Abstract
Colorectal cancer (CRC) is the third most common cancer in the world and the second most common cause of cancer related deaths. Conventional treatment of CRC is comprised of drug (chemotherapeutic agents) administration by parenteral route, which delivers the drug to both normal as well as cancerous tissues, thus leading to numerous undesirable effects. Enormous research is going on worldwide for designing an alternative route of administration, among which oral colon-targeted drug delivery systems have gained immense attention amongst scientific community. Direct delivery of drugs at the site of action leads to an increase in the availability of drugs at the targeted region. This causes a reduction in the amount of drug required to exert same therapeutic effect, thus reducing the incidents of adverse effects. Various maneuvers (pH-dependent, time-dependent and microflora-activated systems) have been attempted by researchers for targeting drugs successfully to the colonic region by circumventing the upper part of gastrointestinal tract. This Editorial article aims to put forth an overview of the formulation technologies that have been developed for attaining colon specific drug delivery for the treatment of CRC.

Abstract
Emulgel is an emerging topical drug delivery system to which if more effort is paid towards its formulation & development with more number of topically effective drugs it will prove a boon for derma care & cosmetology. Emulgels are either emulsion of oil in water or water in oil type, which is gelled by mixing it with gelling agent. Incorporation of emulsion into gel increases its stability & makes it a dual control release system. Due to lack of excess oily bases & insoluble excipients, it shows better drug release as compared to other topical drug delivery system. Presence of gel phase makes it a non greasy & favors good patient compliance. These reviews give knowledge about Emulgel including its properties, advantages, formulation considerations, and its recent advances in research field. All factors such as selection of gelling agent, oil agent, emulsifiers influencing the stability and efficacy of Emulgel are discussed. All justifications are described in accordance with the research work carried out by various scientists. These brief reviews on formulation method have been included. Current research works that carried out on Emulgel are also discussed and highlighted the wide utility of Emulgel in topical drug delivery system. After the vast study, it can be concluded that the Emulgels appear better & effective drug delivery system as compared to other topical drug delivery system. The comprehensive analysis of rheological and release properties will provide an insight into the potential usage of Emulgel formulation as drug delivery system.

Positively charged polymeric nanoparticle reservoirs of terbinafine hydrochloride: preclinical implications for controlled drug delivery in the aqueous humor of rabbits. AAPS PharmSciTech 2013; 14:782-93. [PMID: 23615773 DOI: 10.1208/s12249-013-9964-y] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2012] [Accepted: 03/30/2013] [Indexed: 01/19/2023] Open
Abstract
Frequent instillation of terbinafine hydrochloride (T HCl) eye drops (0.25%, w/v) is necessary to maintain effective aqueous humor concentrations for treatment of fungal keratitis. The current approach aimed at developing potential positively charged controlled-release polymeric nanoparticles (NPs) of T HCl. The estimation of the drug pharmacokinetics in the aqueous humor following ocular instillation of the best-achieved NPs in rabbits was another goal. Eighteen drug-loaded (0.50%, w/v) formulae were fabricated by the nanopreciptation method using Eudragit® RS100 and chitosan (0.25%, 0.5%, and 1%, w/v). Soybean lecithin (1%, w/v) and Pluronic® F68 (0.5%, 1%, and 1.5%, w/v) were incorporated in the alcoholic and aqueous phases, respectively. The NPs were evaluated for particle size, zeta potential, entrapment efficiency percentage (EE%), morphological examination, drug release in simulated tear fluid (pH 7.4), Fourier-transform IR (FT-IR), X-ray diffraction (XRD), physical stability (2 months, 4°C and 25°C), and drug pharmacokinetics in the rabbit aqueous humor relative to an oily drug solution. Spherical, discrete NPs were successfully developed with mean particle size and zeta potential ranging from 73.29 to 320.15 nm and +20.51 to +40.32 mV, respectively. Higher EE% were achieved with Eudragit® RS100-based NPs. The duration of drug release was extended to more than 8 h. FT-IR and XRD revealed compatibility between inactive formulation ingredients and T HCl and permanence of the latter's crystallinity, respectively. The NPs were physically stable, for at least 2 months, when refrigerated. F5-NP suspension significantly (P<0.05) increased drug mean residence time and improved its ocular bioavailability; 1.657-fold.

Abstract
Cancer is the second leading cause of death in the United States. Conventional therapies cause widespread systemic toxicity and lead to serious side effects which prohibit their long term use. Additionally, in many circumstances tumor resistance and recurrence is commonly observed. Therefore, there is an urgent need to identify suitable anticancer therapies that are highly precise with minimal side effects. Curcumin is a natural polyphenol molecule derived from the Curcuma longa plant which exhibits anticancer, chemopreventive, chemo- and radio-sensitization properties. Curcumin's widespread availability, safety, low cost and multiple cancer fighting functions justify its development as a drug for cancer treatment. However, various basic and clinical studies elucidate curcumin's limited efficacy due to its low solubility, high rate of metabolism, poor bioavailability and pharmacokinetics. A growing list of nanomedicine(s) using first line therapeutic drugs have been approved or are under consideration by the Food and Drug Administration (FDA) to improve human health. These nanotechnology strategies may help to overcome challenges and ease the translation of curcumin from bench to clinical application. Prominent research is reviewed which shows that advanced drug delivery of curcumin (curcumin nanoformulations or curcumin nanomedicine) is able to leverage therapeutic benefits by improving bioavailability and pharmacokinetics which in turn improves binding, internalization and targeting of tumor(s). Outcomes using these novel drug delivery systems have been discussed in detail. This review also describes the tumor-specific drug delivery system(s) that can be highly effective in destroying tumors. Such new approaches are expected to lead to clinical trials and to improve cancer therapeutics.
