Abstract
The goal of the present study was to prepare meloxicam (MX) entrapped hybrid particles (HPs) to enhance intestinal permeation and anti-inflammatory activity. MX-HPs were prepared by nanoprecipitation method using lipid, chitosan, poloxamer, and TPGS. The formulations (MX-HPs1, MX-HPs2, MX-HPs3) were evaluated for particle size, entrapment efficiency, and drug release to select the optimized composition and further evaluated for permeation study, stability study, morphology, interaction study, and anti-inflammatory activity by carrageenan-induced rat paw edema test. The prepared MX-HPs showed nano sized particles (198.5 ± 3.7 to 223.8 ± 2.1 nm) and PDI (<0.3), zeta potential (16.5 ± 2.7 to 29.1 ± 3.6 mV), and high entrapment efficiency (75.1 ± 4.7 to 88.5 ± 3.9%). The surface morphology was assessed by transmission electron microscopy and showed non-aggregated particles. Infra-red (IR) spectroscopy of pure MX as well as formulation revealed no drug-polymer interaction and X-ray diffraction confirmed the conversion of crystalline MX into amorphous form. The release study data revealed prolonged MX release for 24 h. The selected optimized hybrid particles (MX-HPs2) revealed a 2.3-fold improved enhancement ratio than free MX. The storage stability and gastrointestinal stability data demonstrated a stable formulation in SIF as well as SGF. The anti-inflammatory activity showed better therapeutic action than pure MX dispersion. From the study, it can be concluded that the prepared MX-HPs may be a promising delivery system for MX in treating inflammatory disorders.

[PMID: 38705851 DOI: 10.1002/asia.202400162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Revised: 04/24/2024] [Accepted: 05/03/2024] [Indexed: 05/07/2024]
Abstract
Hydrotalcite-silver (HT-Ag) nanoparticles have been involved in various daily crucial applications, such as antibacterial, photocatalytic, adsorption, etc. There are many approaches to synthesizing silver nanoparticles (AgNPs) decorated on hydrotalcite (HT) surface and the most used approach is using a strong reducing agent. Thus, affordable but effective "green" reducing agents - Syzygium nervosum leaf extract, are taken into account in this work to solve several issues related to chemical reducing agents. This work aimed to assess the effect of Syzygium nervosum leaf extract as a reducing agent for green synthesis of AgNPs on HT through an optimizing process using response surface methodology (RSM) and the Box-Benken model. The optimal conditions for the synthesis of AgNPs on HT include a reaction time of 6.15 hours, a reaction temperature of 50 °C, and the ratio of diluted Syzygium nervosum leaf extract to reduce AgNO3 of 50.37 mL/mg. Under the optimal conditions, the yield of the reduction reaction reached 77.54 %, close to the theoretical value of 76.97 %. The optimization model was suitable for the experiment data. Besides, the morphology, density, and characteristics of AgNPs on the surface of HT layers have been determined by using Ultraviolet-visible spectroscopy, Field emission scanning electron microscopy (FESEM), High-resolution transmission electron microscopy (HR-TEM), selected area diffraction, X-ray diffraction, Dynamic light scattering (DLS), Infrared (IR) spectroscopy, Fluorescence emission spectroscopy (FE), Brunauer-Emmett-Teller (BET) methods. The spherical AgNPs were synthesized successfully on the surface of HT with the average particle size of 13.0±1.1 nm. Interestingly, HT-Ag hybrid materials can inhibit strongly the growth of E. coli, S. aureus as well as two antibiotic resistance bacterial strains, P. stutzeri B27, and antibiotic resistance E. coli. Especially, the antibacterial activity quantification and durability of the HT-Ag hybrid materials were also tested. Overall, the HT-Ag hybrid materials are very promising for application in material science and biomedicine fields.

AAPS PharmSciTech 2024; 25:145. [PMID: 38918292 DOI: 10.1208/s12249-024-02860-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Accepted: 05/31/2024] [Indexed: 06/27/2024] Open
Abstract
The objective of the current research was to develop abietic acid (AA)-loaded hybrid polymeric nanoparticles (HNPs) for anti-inflammatory and antioxidant activity after oral administration. AAHNPs were developed by microinjection technique and optimized by 3-factor 3-level Box-Behnken design. The AAHNPs were evaluated for morphology, FTIR, X-ray diffraction, in-vitro release, ex-vivo permeation, in-vitro antioxidant, and in-vivo anti-inflammatory activity. The optimized AAHNPs (AAHNPsopt) displayed 384.5 ± 6.36nm of PS, 0.376 of PDI, 23.0 mV of ZP, and 80.01 ± 1.89% of EE. FTIR and X-ray diffraction study results revealed that AA was encapsulated into a HNPs matrix. The AAHNPsopt showed significant (P < 0.05) high and sustained release of AA (86.72 ± 4.92%) than pure AA (29.87 ± 3.11%) in 24h. AAHNPsopt showed an initial fast release of AA (20.12 ± 3.07% in 2h), which succeeded in reaching the therapeutic concentration. The AAHNPsopt showed 2.49-fold higher ex-vivo gut permeation flux than pure AA due to the presence of lipid and surfactant. The AAHNPsopt exhibited significantly (P < 0.05, P < 0.01, P < 0.001) higher antioxidant activity as compared to pure AA at each concentration. AAHNPsopt formulation displayed a significantly (P < 0.05) higher anti-inflammatory effect (21.51 ± 2.23% swelling) as compared to pure AA (46.51 ± 1.74% swelling). From the in-vitro and in-vivo finding, it was concluded that HNPs might be a suitable carrier for the improvement of the therapeutic efficacy of the drug.

Development of a Polymeric Pharmacological Nanocarrier System as a Potential Therapy for Spinocerebellar Ataxia Type 7. Cells 2023; 12:2735. [PMID: 38067163 PMCID: PMC10706302 DOI: 10.3390/cells12232735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 11/08/2023] [Accepted: 11/16/2023] [Indexed: 12/18/2023] Open
Abstract
Spinocerebellar ataxia type 7 (SCA7) is an autosomal-dominant inherited disease characterized by progressive ataxia and retinal degeneration. SCA7 belongs to a group of neurodegenerative diseases caused by an expanded CAG repeat in the disease-causing gene, resulting in aberrant polyglutamine (polyQ) protein synthesis. PolyQ ataxin-7 is prone to aggregate in intracellular inclusions, perturbing cellular processes leading to neuronal death in specific regions of the central nervous system (CNS). Currently, there is no treatment for SCA7; however, a promising approach successfully applied to other polyQ diseases involves the clearance of polyQ protein aggregates through pharmacological activation of autophagy. Nonetheless, the blood-brain barrier (BBB) poses a challenge for delivering drugs to the CNS, limiting treatment effectiveness. This study aimed to develop a polymeric nanocarrier system to deliver therapeutic agents across the BBB into the CNS. We prepared poly(lactic-co-glycolic acid) nanoparticles (NPs) modified with Poloxamer188 and loaded with rapamycin to enable NPs to activate autophagy. We demonstrated that these rapamycin-loaded NPs were successfully taken up by neuronal and glial cells, demonstrating high biocompatibility without adverse effects. Remarkably, rapamycin-loaded NPs effectively cleared mutant ataxin-7 aggregates in a SCA7 glial cell model, highlighting their potential as a therapeutic approach to fight SCA7 and other polyQ diseases.

Abstract
The barrier functionalities of the skin offer a major but not insuperable hindrance for fabrication of skin delivery effective systems. This work aimed to develop an optimized lipid polymer hybrid nanoparticle and assess the skin delivery effectiveness of hydrocortisone (9.872 ± 0.361 × 10-3 cm2/h) of a drug through the skin from an optimized formulation when compared with a drug solution. Meanwhile, histological examination after topical application of the optimized formulation showed a safe increase in epidermal thickness. In vivo, the optimized formulation showed promising anti-inflammatory activity in a croton oil-induced ear rosacea model. As an excellent anti-inflammatory agent, these findings propose that the use of lipomers could be a promising strategy to improve the topical effectiveness of hydrocortisone acetate (HCA) against inflammatory diseases. Collectively, these results support our view that lipid polymer hybrid nanoparticles can proficiently deliver hydrocortisone to the skin in treating skin inflammatory conditions.

Abstract
The objective of the current work was to fabricate, optimize and assess olive oil/phytosomal nanocarriers to improve quercetin skin delivery. Olive oil/phytosomal nanocarriers, prepared by a solvent evaporation/anti-solvent precipitation technique, were optimized using a Box–Behnken design, and the optimized formulation was appraised for in vitro physicochemical characteristics and stability. The optimized formulation was assessed for skin permeation and histological alterations. The optimized formulation (with an olive oil/PC ratio of 0.166, a QC/PC ratio of 1.95 and a surfactant concentration of 1.6%), and with a particle diameter of 206.7 nm, a zeta potential of −26.3 and an encapsulation efficiency of 85.3%, was selected using a Box–Behnken design. The optimized formulation showed better stability at ambient temperature when compared to refrigerating temperature (4 °C). The optimized formulation showed significantly higher skin permeation of quercetin when compared to an olive-oil/surfactant-free formulation and the control (~1.3-fold and 1.9-fold, respectively). It also showed alteration to skin barriers without remarkable toxicity aspects. Conclusively, this study demonstrated the use of olive oil/phytosomal nanocarriers as potential carriers for quercetin—a natural bioactive agent—to improve its skin delivery.

[PMID: 36925532 PMCID: PMC10010992 DOI: 10.1016/j.heliyon.2023.e14281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 02/23/2023] [Accepted: 03/01/2023] [Indexed: 03/11/2023] Open
Abstract
Itraconazole (ICZ) is a broad spectrum antifungal drug, but used as second or third line therapy due to its low and erratic oral bioavailability. This work was carried out to prepare and characterize matrix type lipid-polymer hybrid nanoparticles (LPHNPs) for dissolution enhancement of ICZ. LPHNPs were prepared using solvent diffusion/emulsification technique. Matrix LPHNPs were composed of chitosan (polymer), glyceryl monostearate (lipid) and poloxamer 188 (stabilizer). LPHNPs loaded with ICZ (LPHNPs-1, LPHNPs-2, LPHNPs-3 and LPHNPs-4) were developed using varying concentration of chitosan whereas LPHNPs (LPHNPs-5, LPHNPs-6, LPHNPs-7 and LPHNPs-8) were prepared using varying concentrations of poloxamer 188. LPHNPs loaded with ICZ were further evaluated for entrapment efficiency, particle size, polydispersity index (PDI), zeta potential and dissolution profiles at biorelevant pH conditions. The particle size (LPHNPs-1 to LPHNPs-4) was found to be in range of 421-588 nm with PDI values 0.34-0.41. The particles size of LPHNPs-5 to LPHNPs-8 was found to be in range of 489-725 nm with PDI 0.34-0.74. The entrapment efficiency of LPHNPs-1 to LPHNPs-4 was found to be in range of 85.21%-91.34%. The entrapment efficiency of LPHNPs-5 to LPHNPs-8 was found to be in range 78.32%-90.44%. . The scanning electron microscopy of optimized formulations LPHNPs-1 and LPHNPs-5 indicated formation of oval shaped nanoparticles. DSC thermogram of ICZ loaded LPHNPs also depicted the conversion of crystalline form of ICZ into amorphous form demonstrating the internalization and dissolution enhancement of drug in the hybrid matrix. The cumulative drug dissolved at acidic pH 1.2 was found to be 23.3% and 19.8% for LPHNPs-1 and LPHNPs-5 respectively. Similarly at basic pH values 7.4, cumulative amount of drug dissolved was 90.2% and 83.4% for LPHNPs-1 and LPHNPs-5 respectively. Drug dissolution kinetics exhibited fickian diffusion best described by Korse-meyer Peppas model. The results suggested that chitosan and glyceryl monostearate based matrix LPHNPs could be used as promising approach for dissolution enhancement of ICZ which could further increase its bioavailability.

Abstract
The clinical application of phytochemicals such as thymoquinone (THQ) is restricted due to their limited aqueous solubility and oral bioavailability. Developing mucoadhesive nanocarriers to deliver these natural compounds might provide new hope to enhance their oral bioavailability. Herein, this investigation aimed to develop THQ-loaded lipid-polymer hybrid nanoparticles (THQ-LPHNPs) based on natural polymer chitosan. THQ-LPHNPs were fabricated by the nanoprecipitation technique and optimized by the 3-factor 3-level Box−Behnken design. The optimized LPHNPs represented excellent properties for ideal THQ delivery for oral administration. The optimized THQ-LPHNPs revealed the particles size (PS), polydispersity index (PDI), entrapment efficiency (%EE), and zeta potential (ZP) of <200 nm, <0.25, >85%, and >25 mV, respectively. THQ-LPHNPs represented excellent stability in the gastrointestinal milieu and storage stability in different environmental conditions. THQ-LPHNPs represented almost similar release profiles in both gastric as well as intestinal media with the initial fast release for 4 h and after that a sustained release up to 48 h. Further, the optimized THQ-LPHNPs represent excellent mucin binding efficiency (>70%). Cytotoxicity study revealed much better anti-breast cancer activity of THQ-LPHNPs compared with free THQ against MDA-MB-231 and MCF-7 breast cancer cells. Moreover, ex vivo experiments revealed more than three times higher permeation from the intestine after THQ-LPHNPs administration compared to the conventional THQ suspension. Furthermore, the THQ-LPHNPs showed 4.74-fold enhanced bioavailability after oral administration in comparison with the conventional THQ suspension. Therefore, from the above outcomes, mucoadhesive LPHNPs might be suitable nano-scale carriers for enhanced oral bioavailability and therapeutic efficacy of highly lipophilic phytochemicals such as THQ.

Abstract
The aim of this study was to employ nanoparticles as drug carriers. The research involved the design of cromolyn polyamide-disulfide nanocomposites to overcome the problem of frequent cromolyn doses and improve their properties. The cromolyn polyamide-disulfide samples were prepared using several amounts of cromolyn and sodium polyamide-disulfide polymer at different pH values. Analysis of variance (ANOVA) was performed to obtain the significant independent variables affecting the dependent response by using a
value lower than 0.05. The nanocomposites produced were characterized using Fourier transform infrared (FTIR) spectroscopy and in vitro release. An FTIR test was used to evaluate the functional groups of cromolyn in nanocomposites, which indicated that the drug was encapsulated inside the polymer. All data indicated the presence of cromolyn in the nanocomposites. The release profile of nanocomposites was found to be sustained. Therefore, the outcome of this research project could be a starting point for further work to optimize and assess polyamide-disulfide polymers for delivering another drug.

Abstract
Apigenin (AGN) is a potent phytochemical with strong antioxidant and anticancer potential. But its therapeutic efficacy is limited due to its high lipophilic characteristics. Therefore, the present investigation aimed to develop AGN-loaded polymer-lipid hybrid nanoparticles (AGN-PLHNPs). Herein, we successfully developed AGN-PLHNPs and optimized them by a 33-Box-Behnken de-sign. The poly (lactic-co-glycolic acid) (PLGA; coded as F1), phospholipon 90 G (PL-90G; coded as F2), and poloxamer 188 (P-188; coded as F3) were considered as the independent factors while particle size (PS; coded as R1), entrapment efficiency (%EE; R2), and cumulative drug release (%CDR; R3) were selected as dependent responses. The average PS, %EE, and %CDR of the AGN-PLHNPs were observed in the range of 101.93 nm to 175.26 nm, 58.35% to 81.14%, and 71.21% to 93.31%, respectively. The optimized AGN-PLHNPs revealed better homogeneity (poly-dispersity index < 0.2) and colloidal stability with high zeta potential (>25 mV). It also exhibited fast release in the initial 4 h after that sustained release up to 48 h of study. Moreover, the results of both DPPH as well as ABTS assays revealed significant improvement in the antioxidant activity. Furthermore, the optimized AGN-PLHNPs exhibited enhanced cytotoxicity efficacy against MCF-7 as well as MDA-MB-231 breast cancer cell lines.

Abstract
Piperine (PPN), one of the most investigated phytochemicals, is known to have excellent therapeutic efficacy against a variety of ailments including breast cancer. However, its physicochemical properties such as poor aqueous solubility restrict its clinical application. Therefore, the present investigation was designed to develop PPN encapsulated lipid polymer hybrid nanoparticles (PPN-LPHNPs) to overcome the limitation. The developed PPN-LPHNPs were optimized by the three-factor, three-level Box−Behnken design (33-BBD). The optimized PPN-LPHNPs were then evaluated for their drug release profile, cytotoxicity assay against MDA-MB-231 and MCF-7 cells, and gastrointestinal stability as well as colloidal stability. In addition, the optimized PPN-LPHNPs were evaluated for ex vivo intestinal permeation and in vivo pharmacokinetic in albino Wistar rats. As per the results, the optimized PPN-LPHNPs showed a small average particles size of <160 nm with a low (<0.3) polydispersity index, and highly positive surface charge (>+20 mV). PPN-LPHNPs revealed excellent gastrointestinal as well as colloidal stability and sustained release profiles up to 24 h. Furthermore, PPN-LPHNPs revealed excellent cytotoxicity against both MDA-MB-231 and MCF-7 cancer cells compared to the free PPN. Moreover, animal studies revealed that the PPN-LPHNPs exhibited a 6.02- and 4.55-fold higher intestinal permeation and relative oral bioavailability, respectively, in comparison to the conventional PPN suspension. Thus, our developed LPHNPs present a strong potential for improved delivery of PPN.

Abstract
The study aims at formulation and optimization of resveratrol and humic acid co-encapsulated colloidal polymeric nanocarriers to improve stability, oral bioavailability, and antiradical activity of water-insoluble, resveratrol. The eudragit E100 polymeric material was used to fabricate resveratrol and humic acid co-encapsulated oral colloidal polymeric nanocarriers (Res-HA-co-CPNs) using emulsification-diffusion-evaporation method. Taguchi orthogonal array design was employed to check the effect of formulation factors on in vitro physicochemical characteristics. The optimized formulation was further evaluated for oral bioavailability as well as for antiradical potential. Optimized Res-HA-co-CPNs demonstrated spherical and smooth surface including mean particle size, 120.56 ± 18.8 nm; polydispersity index, 0.122; zeta potential, +38.25 mV; and entrapment efficiency, 82.37 ± 1.49%. Solid-state characterization confirmed the amorphous characteristic of optimized Res-HA-co-CPNs. In vitro release profile of Res-HA-co-CPNs showed sustained release behavior up to 48 h and CPNs were found to remain stable at the refrigerated condition for 6 months. In vivo pharmacokinetic studies revealed significant (p < 0.05) improvement of ∼62.76-fold in oral bioavailability. The radical-scavenging activity was found to be increased with time and after 72 h, it was analogous to pure Res. IC50 values were reported to be decreased with time. Henceforth, developed Res-HA-co-CPNs was proven to be a proficient dosage form to increase stability, oral bioavailability, and antiradical activity of resveratrol.HighlightsResveratrol-humic acid co-encapsulated colloidal polymeric nanocarriers (Res-HA-co-CPNs) were fabricated by emulsification-diffusion-evaporation method and optimized by Taguchi orthogonal array design.The Res-HA-co-CPNs revealed favorable mean particle size and percent encapsulation efficiency with a spherical and smooth surface.The Res-HA-co-CPNs showed diffusion-controlled release of Res and were found to be stable at the refrigerated condition for 6 months.The optimized Res-HA-co-CPNs demonstrated significantly (p < 0.05) higher oral bioavailability with respect to pure Res and PM.The optimized Res-HA-co-CPNs demonstrated higher radical-scavenging activity with respect to time.

Abstract
Polymer-lipid hybrid nanoparticles (PLHNPs) are novel nanoplatforms for the effective delivery of a lipophilic drug in the management of a variety of solid tumors. The present work was designed to develop exemestane (EXE) encapsulated D-alpha-tocopheryl polyethylene glycol succinate (TPGS) based PLHNPs (EXE-TPGS-PLHNPs) for controlled delivery of EXE for breast cancer management. EXE-TPGS-PLHNPs were formulated by single-step nano-precipitation technique and statistically optimized by a 33Box-Behnken design using Design expert®software. The polycaprolactone (PCL;X1), phospholipon 90 G (PL-90G;X2), and surfactant (X3) were selected as independent factors while particles size (PS;Y1), polydispersity index (PDI;Y2), and %entrapment efficiency (%EE;Y3) were chosen as dependent factors. The average PS, PDI, and %EE of the optimized EXE-TPGS-PLHNPs was observed to be 136.37 ± 3.27 nm, 0.110 ± 0.013, and 88.56 ± 2.15% respectively. The physical state of entrapped EXE was further validated by Fourier-transform infrared spectroscopy, differential scanning calorimetry, and powder x-ray diffraction that revealed complete encapsulation of EXE in the hybrid matrix of PLHNPs with no sign of significant interaction between drug and excipients.In vitrorelease study in simulated gastrointestinal fluids revealed initial fast release for 2 h after that controlled release profile up to 24 h of study. Moreover, optimized EXE-TPGS-PLHNPs exhibited excellent stability in gastrointestinal fluids as well as colloidal stability in different storage concentrations. Furthermore, EXE-TPGS-PLHNPs exhibited distinctively higher cellular uptake and time and dose-dependent cytotoxicity against MCF-7 breast tumor cells compared to EXE-PLHNPs without TPGS and free EXE. The obtained results suggested that EXE-TPGS-PLHNPs can be a promising platform for the controlled delivery of EXE for the effective treatment of breast cancer.

Abstract
PURPOSE The work was performed to investigate the feasibility of preparing ocular inserts loaded with Poly-ε-Caprolactone (PCL) nanoparticles as a sustained ocular delivery system. METHODS First, Atorvastatin Calcium-Poly-ε-Caprolactone (ATC-PCL) nanoparticles were prepared and characterized. Then, the optimized nanoparticles were loaded within inserts formulated with Methylcellulose (MC) and Polyvinyl Alcohol (PVA) by a solvent casting technique and evaluated physically, for in-vitro drug release profile. Finally, an in-vivo study was performed on the selected formulation to prove non-irritability and sustained ocular anti-inflammatory efficacy compared with free drug-loaded ocuserts. RESULTS The results revealed (ATC-PCL) nanoparticles prepared with 0.5% pluronic F127 were optimized with 181.72±3.6 nm particle size, 0.12±0.02 (PDI) analysis, -27.4± 0.69 mV zeta potential and 62.41%±4.7% entrapment efficiency. Nanoparticles loaded ocuserts manifested compatibility between drug and formulation polymers. Moreover, formulations complied with average weight 0.055±0.002 to 0.143±0.023 mg, and accepted pH. ATC-PCL nanoparticles loaded inserts prepared by 5% MC showed more sustained, prolonged in-vitro release over 24h. In-vivo study emphasized non-irritability, ocular anti-inflammatory effectiveness represented by smaller lid closure scores, and statistically significant lowering in PMN count after 3h. CONCLUSION These findings proposed a possibly simple, new and affordable price technique to prepare promising (ATC-PCL) nanoparticles loaded inserts to achieve sustained release with prolonged antiinflammatory efficacy.

Hydrophobic ion pair loaded self-emulsifying drug delivery system (SEDDS): A novel oral drug delivery approach of cromolyn sodium for management of bronchial asthma. Int J Pharm 2020; 585:119494. [PMID: 32505578 DOI: 10.1016/j.ijpharm.2020.119494] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 05/29/2020] [Accepted: 05/30/2020] [Indexed: 01/01/2023]
Abstract
The aim of the present study is to develop a self-emulsifying drug delivery system (SEDDS) for the hydrophobic ion pair (HIP) complex of cromolyn sodium (CS), in order to enhance its intestinal absorption and biological activity. Two ion pairing agents (IPAs) were investigated: hexadecyl pyridininum chloride (HPC) and myristyl trimethyl ammonium bromide (MTAB). The optimum binding efficiency for complexation between investigated IPAs and CS was observed at a molar ratio of 1.5:1, where CS binding efficiency was found to be 76.10 ± 2.12 and 91.37 ± 1.73% for MTAB and HPC, respectively. The two prepared complexes exhibited a significant increase in partition coefficient indicating increased lipophilicity. The optimized CS-HIP complex was incorporated into SEDDS formulations. SEDDS formulations F2 (40% oleic acid, 40% BrijTM98, 20% propylene glycol) and F3 (25% oleic acid, 50% BrijTM98, 25% propylene glycol) exhibited nanometric droplet diameters with monodisperse distribution and nearly neutral zeta potential values. Ex vivo intestinal permeation study, using the non-everted gut sac technique, revealed a significantly higher cumulative amount of permeated drug, after 2 h, for F2 and F3 (53.836 and 77.617 µg/cm2, respectively) compared to 8.649 µg/cm2 for plain CS solution. The in vivo evaluation of plain CS solution compared to F2 and F3 was conducted in an ovalbumin sensitization-induced bronchial asthma rat model. Lung function parameters (tidal volume and peak expiratory flow), biochemical parameters (interleukin-5, immunoglobulin-E, myeloperoxidase and airway remodelling parameters) were assessed in addition to histopathological examination. The results indicated the superiority of F3 followed by F2 compared to plain CS solution for prophylaxis of bronchial asthma in rats.

Abstract
INTRODUCTION A promising approach that has recently emerged to overcome the complex biobarriers and interrelated challenges associated with oral drug absorption is to combine the benefits of polymeric and lipid-based nanocarriers within one hybrid system. This multifaceted formulation strategy has given rise to a plethora of polymer-lipid hybrid (PLH) systems with varying nanostructures and biological activities, all of which have demonstrated the ability to improve the biopharmaceutical performance of a wide range of challenging therapeutics. AREAS COVERED The multitude of polymers that can be combined with lipids to exert a synergistic effect for oral drug delivery have been identified, reviewed and critically evaluated. Specific focus is attributed to preclinical studies performed within the past 5 years that have elucidated the role and mechanism of the polymer phase in altering the oral absorption of encapsulated therapeutics. EXPERT OPINION The potential of PLH systems has been clearly identified; however, improved understanding of the structure-activity relationship between PLH systems and oral absorption is fundamental for translating this promising delivery approach into a clinically relevant formulation. Advancing research within this field to identify optimal polymer, lipid combinations and engineering conditions for specific therapeutics are therefore encouraged.

Abstract
Quercetin (Qu), is a flavonoid known to have anti-diabetic effects owing to its antioxidant property, thus promoting regeneration of the pancreatic islets, ultimately increasing insulin secretion. But the therapeutic application of Qu is hampered by its low oral bioavailability and its unfavourable physicochemical characteristics. The present work aimed at formulation of Quercetin loaded Soluplus® micelles (SMs) so as to enhance its bioavailability and provide prolonged release for the management of diabetes. Box-Behnken response surface methodology was employed to optimize the formulation prepared using co-solvent evaporation method. Physicochemical characterization confirmed the nano-spherical nature of Quercetin loaded Soluplus® micelles (Qu-SMs) with average particle size ranging from 85-108nm, encapsulation efficiency of 63-77%. Solid state characterization confirmed the encapsulation of Qu in the micelles without any incompatibilities. Moving forward, the results of in vitro study revealed prolonged and slow release of Qu from the developed formulations. The in vivo pharmacokinetic study revealed improved bioavailability by enveloping the drug in SMs. Moreover, the study performed to evaluate the efficiency in diabetes treatment revealed an enhanced anti-diabetic effect. Thus, Qu-SMs can serve as potential carriers aimed at improving the anti-diabetic property of Qu.

Sharma M, Sharma R. Implications of designing a bromelain loaded enteric nanoformulation on its stability and anti-inflammatory potential upon oral administration. RSC Adv 2018; 8:2541-2551. [PMID: 35541457 PMCID: PMC9077456 DOI: 10.1039/c7ra13555f] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Accepted: 01/03/2018] [Indexed: 12/31/2022] Open
Abstract
The objective of the present investigation was to develop an enteric nano-formulation of bromelain to improve its stability and anti-inflammatory potential. Bromelain loaded nanoparticles (Br-NPs) were developed using a Eudragit L 100 polymer by a double emulsion solvent evaporation method to obtain gastro-resistant properties. Br-NPs were characterized for particle size (248.89 ± 22.76 nm), zeta potential (-27.34 ± 2.17 mV), entrapment efficiency (85.42 ± 5.34%), surface morphology (spherical) and in vitro release profile. Infrared spectroscopy confirmed the entrapment of bromelain while thermal and pXRD analysis concomitantly corroborated the reduced crystallinity of bromelain in nanoparticles. Formulations showed gastro-resistant behavior at gastric pH and sustained bromelain release up to 10 h in phosphate buffer at pH 6.8 and followed Higuchi square root release kinetics. The optimized lyophilized formulation ensured 2 year shelf-life at room temperature. In vivo studies revealed significantly improved performance of entrapped bromelain in inhibiting carrageenan induced paw edema by mitigating leucocyte migration and release of nitric oxide, TNFα and IL-1β in paw compared to bromelain solution. In conclusion, enteric Br-NPs could be a viable drug delivery system for effective oral bromelain delivery in inflammatory conditions.

Abstract
AIM To enhance oral bioavailability and chemotherapeutic efficacy of naringenin (NG) by fabricating the NG-encapsulated Soluthin-maltodextrin-based nanocarrier (NC) system. MATERIALS & METHODS NG-encapsulated nanocarriers (NG/NCs) were developed, and in vitro physicochemically characterized. Furthermore, Wistar rats were used to evaluate the pharmacokinetic profile. Furthermore, in vitro and in vivo colorectal cancer efficacy was evaluated in BALB/c mice-bearing colon-26 cells. RESULTS The NG/NCs demonstrated favorable mean particle size (176 ± 2.35 nm) and percent entrapment efficiency (70.83 ± 4.55%), respectively. The oral bioavailability was found to be approximately 116-fold higher and in vitro cytotoxicity exhibited approximately 21-fold reduction as compared with pure NG. Moreover, optimized NG/NCs demonstrated significant tumor suppression compared with pure NG in vivo. CONCLUSION The NG/NCs would be an efficient formulation for enhancing oral bioavailability and chemotherapeutic efficacy of NG.

Abstract
The objective of the study was to improve the bioavailability and anticancer potential of naringenin (NRG) by developing a drug-loaded polymeric nanodelivery system. NRG-loaded eudragit E100 nanoparticle (NRG-EE100-NPs) system was developed and physicochemically characterized. In vivo pharmacokinetic and in vitro cytotoxicity abilities of the NRG-EE100-NPs were investigated. In vivo anticancer activity was evaluated in murine BALB/c mice-bearing colorectal tumor. The NRG-EE100-NPs had an optimum mean particle size (430.42 ± 5.78 nm), polydispersity index (0.283 ± 0.089) with percent entrapment efficiency (68.83 ± 3.45%). The NRG-EE100-NPs demonstrated significant higher bioavailability (∼96-fold; p <0.05) as well as cytotoxicity (∼16-fold; p <0.001) as compared to free NRG. Furthermore, NRG-EE100-NPs indicated significant tumor suppression (p <0.01) subsequently improvement in survival rate compared to free NRG in vivo. Thus, the physicochemical properties and colorectal cancer efficacy of NRG were improved by successful encapsulating in cationic-polymeric nanoparticle system.

Development and optimization of methotrexate-loaded lipid-polymer hybrid nanoparticles for controlled drug delivery applications. Int J Pharm 2017; 533:156-168.

Abstract
Lipid-polymer hybrid nanoparticles (LPHNPs) are emerging platforms for drug delivery applications. In the present study, methotrexate loaded LPHNPs consisted of PLGA and Lipoid S100 were fabricated by employing a single-step modified nanoprecipitation method combined with self-assembly. A three factor, three level Box Behnken design using Design-Expert® software was employed to access the influence of three independent variables on the particle size, drug entrapment and percent drug release. The optimized formulation was selected through numeric optimization approach. The results were supported with the ANOVA analysis, regression equations and response surface plots. Transmission electron microscope images indicated the nanosized and spherical shape of the LPHNPs with fair size distribution. The nanoparticles ranged from 176 to 308nm, which increased with increased polymer concentration. The increase in polymer and lipid concentration also increased the drug entrapment efficiency. The in vitro drug release was in range 70.34-91.95% and the release mechanism follow the Higuchi model (R2=0.9888) and Fickian diffusion (n<0.5). The in vitro cytotoxicity assay and confocal microscopy of the optimized formulation demonstrate the good safety and better internalization of the LPHNPs. The cell antiproliferation showed the spatial and controlled action of the nanoformulation as compared to the plain drug solution. The results suggest that LPHNPs can be a promising delivery system envisioned to safe, stable and potentially controlled delivery of methotrexate to the cancer cells to achieve better therapeutic outcomes.

Tinidazole functionalized homogeneous electrospun chitosan/poly (ε-caprolactone) hybrid nanofiber membrane: Development, optimization and its clinical implications.

Abstract
We have prepared tinidazole (TNZ) functionalized biodegradable chitosan (CH)/poly (ε-caprolactone) (PCL) mucoadhesive hybrid nanofiber membrane (TNZ-PCHNF) to alleviate existing shortcomings in treatment of periodontitis. Box-Behnken design was employed for evaluating influence of formulation and processing variables on quality of final formulation. Optimized nanofiber membrane was subjected to solid-state and surface characterization studies using FTIR, DSC, XRD, SEM and AFM, which revealed that TNZ was entrapped in an amorphous form inside smooth and uniform cylindrical nanofibers without any physicochemical interaction with excipients. The optimized TNZ-PCHNF membrane had a diameter of 143.55±8.5nm and entrapment efficiency of 83.25±1.8%. In vitro drug release and antibacterial study demonstrated capability of the developed nanofiber membranes for efficiently delivering TNZ in a sustained manner up to 18days, and its ability to inhibit bacterial growth, respectively. Further, reduction of contact angle (from 123.4±2.5 to 27.4±2.3) revealed that blending of CH with PCL increases hydrophilicity of the nanofiber membrane. MTT assay and CLSM study suggested that nanofiber membrane was devoid of cytotoxicity on mouse fibroblasts. Moreover, preliminary clinical trials on patients proved therapeutic efficacy of the nanofiber membrane by eliciting a significant (p<0.05) decrease in clinical markers of periodontitis.
