Khan MS, Fatima M, Wahab S, Khalid M, Kesharwani P. Gallic acid loaded self-nano emulsifying hydrogel-based drug delivery system against onychomycosis. Nanomedicine (Lond) 2024:1-19. [PMID: 39143900 DOI: 10.1080/17435889.2024.2386923] [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: 05/09/2024] [Accepted: 07/29/2024] [Indexed: 08/16/2024] Open
Abstract
Aim: To developed and investigate gallic acid (GA) loaded self-nanoemulsifying drug delivery systems (SNEDDS) for treating onychomycosis via transungual route. Materials & methods: The SNEDDS were prepared by direct dispersion technique and were evaluated for characteristics parameters using Fourier transform infrared, differential scanning calorimetry, confocal microscopy, transmission electron microscopy and zeta sizer. Furthermore, the safety of prepared formulation was evaluated via Hen's egg test-chorioallantoic membrane study and stability was confirmed using different parameters. Also, its effectiveness was evaluated against fungal strain Trichophyton mentagrophytes. Results: The SNEDDS displayed a particle size of 199.8 ± 4.21 nm and a zeta potential; of -22.75 ± 2.09 mV. Drug release study illustrated a sustained release pattern with a release of 70.34 ± 0.20% over a period of 24 h. The penetration across the nail plate was found to be 1.59 ± 0.002 µg/mg and 0.97 ± 0.001 µg/mg for GA loaded SNEDDS and GA solution respectively. An irritation score of 0.52 ± 0.005 and 3.84 ± 0.001 was reported for GA loaded SNEDDS hydrogel and GA solution, indicating a decrease in the drug's irritation potential from slightly irritating to non irritating due to its entrapment within the SNEDDS. Conclusion: GA loaded SNEDDS has potential to address limitations of conventional treatments, enhancing the drug's efficacy and reducing the likelihood of resistance in the treatment of Onychomycosis.

Abstract
Ivermectin (IVM), a drug originally used for treating parasitic infections, is being explored for its potential applications in cancer therapy. Despite the promising anti-cancer effects of IVM, its low water solubility limits its bioavailability and, consequently, its biological efficacy as an oral formulation. To overcome this challenge, our research focused on developing IVM-loaded lipid polymer hybrid nanoparticles (LPHNPs) designed for potential pulmonary administration. IVM-loaded LPHNPs were developed using the emulsion solvent evaporation method and characterized in terms of particle size, morphology, entrapment efficiency, and release pattern. Solid phase characterization was investigated by Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). Using a Twin stage impinger (TSI) attached to a device, aerosolization properties of the developed LPHNPs were studied at a flow rate of 60 L/min, and IVM was determined by a validated HPLC method. IVM-loaded LPHNPs demonstrated spherical-shaped particles between 302 and 350 nm. Developed formulations showed an entrapment efficiency between 68 and 80% and a sustained 50 to 60% IVM release pattern within 96 h. Carr's index (CI), Hausner ratio (HR), and angle of repose (θ) indicated proper flowability of the fabricated LPHNPs. The in vitro aerosolization analysis revealed fine particle fractions (FPFs) ranging from 18.53% to 24.77%. This in vitro study demonstrates the potential of IVM-loaded LPHNPs as a delivery vehicle through the pulmonary route.

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.

QbD-Assisted Development and Optimization of Doxycycline Hyclate- and Hydroxyapatite-Loaded Nanoparticles for Periodontal Delivery. ACS OMEGA 2024; 9:4455-4465. [PMID: 38313517 PMCID: PMC10831838 DOI: 10.1021/acsomega.3c07092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2023] [Revised: 12/27/2023] [Accepted: 01/04/2024] [Indexed: 02/06/2024]
Abstract
The current research aims to develop a carrier system for the delivery of a matrix metalloproteinase (MMP) inhibitor along with a bioceramic agent to the periodontal pocket. It is proposed that the present system, if given along with a systemic antibiotic, would be a fruitful approach for periodontitis amelioration. To fulfill the aforementioned objective, a doxycycline hyclate- and hydroxyapatite-adsorbed composite was prepared by a physical adsorption method and successfully loaded inside sodium alginate-chitosan nanoparticles and optimized based on particle size and drug content. Optimized formulation was then subjected to different evaluation parameters like encapsulation efficiency, hydroxyapatite content, ζ potential, surface morphology, in vitro drug release, cell line studies, and stability studies. For the optimized formulation, particle size, polydispersity index (PDI), entrapment efficiency, ζ potential, and drug content were found to be 336.50 nm, 0.23, 41.77%, -13.85 mV, and 14.00%, respectively. The surface morphology of the placebo and adsorbed composite-loaded nanoparticles as observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed the spherical shape and rough surface of the particles. In gingival crevicular fluid (GCF) 7.6, a sustained drug release profile was obtained up to 36 h. In vitro % viability studies performed on murine fibroblast cells (NIH3T3) and human periodontal ligament (hPDL) cell lines confirmed the proliferative nature of the formulation. Also, when subjected to stability studies for 4 weeks, particle size, PDI, and drug content did not vary considerably, thereby ensuring the stable nature of nanoparticles. Henceforth, sodium alginate-chitosan nanoparticles appeared to be a good carrier system for doxycycline hyclate and hydroxyapatite for periodontal therapy. If given along with a system antibiotic, the system will serve as a fruitful tool for infection-mediated periodontal regeneration and healing.

In Vitro and Biological Evaluation of Oral Fast-Disintegrating Films Containing Ranitidine HCl and Syloid ® 244FP-Based Ternary Solid Dispersion of Flurbiprofen. Pharmaceutics 2024; 16:164. [PMID: 38399224 PMCID: PMC10892821 DOI: 10.3390/pharmaceutics16020164] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 01/17/2024] [Accepted: 01/17/2024] [Indexed: 02/25/2024] Open
Abstract
Flurbiprofen (FBP), a nonsteroidal anti-inflammatory drug (NSAID), is commonly used to treat the pain of rheumatoid arthritis, but in prolonged use it causes gastric irritation and ulcer. To avoid these adverse events of NSAIDs, the simultaneous administration of H2 receptor antagonists such as ranitidine hydrochloride (RHCl) is obligatory. Here, we developed composite oral fast-disintegrating films (ODFs) containing FBP along with RHCl to provide a gastroprotective effect as well as to enhance the solubility and bioavailability of FBP. The ternary solid dispersion (TSD) of FBP was fabricated with Syloid® 244FP and poloxamer® 188 using the solvent evaporation technique. The synthesized FBP-TSD (coded as TSD) was loaded alone (S1) and in combination with plain RHCl (S2) in the composite ODFs based on hydroxypropyl methyl cellulose E5 (HPMC E5). The synthesized composite ODFs were evaluated by in vitro (thickness, folding endurance, tensile strength, disintegration, SEM, FTIR, XRD and release study) and in vivo (analgesic, anti-inflammatory activity, pro-inflammatory cytokines and gastroprotective assay) studies. The in vitro characterization revealed that TSD preserved its integrity and was effectively loaded in S1 and S2 with optimal compatibility. The films were durable and flexible with a disintegration time ≈15 s. The release profile at pH 6.8 showed that the solid dispersion of FBP improved the drug solubility and release when compared with pure FBP. After in vitro studies, it was observed that the analgesic and anti-inflammatory activity of S2 was higher than that of pure FBP and other synthesized formulations (TSD and S1). Similarly, the level of cytokines (TNF-α and IL-6) was also markedly reduced by S2. Furthermore, a gastroprotective assay confirmed that S2 has a higher safety profile in comparison to pure FBP and other synthesized formulations (TSD and S1). Thus, composite ODF (S2) can effectively enhance the FBP solubility and its therapeutic efficacy, along with its gastroprotective effect.

Abstract
A PEGylated Tween 80-functionalized chitosan-lipidic (PEG-T-Chito-Lip) nano-vesicular hybrid was developed for intranasal administration as an alternative delivery route to help improve the poor oral bioavailability of BCS class-III model/antiemetic (metoclopramide hydrochloride; MTC). The influence of varying levels of chitosan, cholesterol, PEG 600, and Tween 80 on the stability/release parameters of the formulated nanovesicles was optimized using Draper-Lin Design. Two optimized formulations (Opti-Max and Opti-Min) with both maximized and minimized MTC-release goals, were predicted, characterized, and proved their vesicular outline via light/electron microscopy, along with the mutual prompt/extended in-vitro release patterns. The dual-optimized MTC-loaded PEG-T-Chito-Lip nanovesicles were loaded in intranasal in-situ gel (ISG) and further underwent in-vivo pharmacokinetics/nose-to-brain delivery valuation on Sprague-Dawley rats. The absorption profiles in plasma (plasma-AUC0-∞) of the intranasal dual-optimized MTC-loaded nano-vesicular ISG formulation in pretreated rats were 2.95-fold and 1.64-fold more than rats pretreated with orally administered MTC and intranasally administered raw MTC-loaded ISG formulation, respectively. Interestingly, the brain-AUC0-∞ of the intranasal dual-optimized MTC-loaded ISG was 10 and 3 times more than brain-AUC0-∞ of the MTC-oral tablet and the intranasal raw MTC-loaded ISG, respectively. It was also revealed that the intranasal dual-optimized ISG significantly had the lowest liver-AUC0-∞ (862.19 ng.g-1.h-1) versus the MTC-oral tablet (5732.17 ng.g-1.h-1) and the intranasal raw MTC-loaded ISG (1799.69 ng.g-1.h-1). The brain/blood ratio profile for the intranasal dual-optimized ISG was significantly enhanced over all other MTC formulations (P < 0.05). Moreover, the 198.55% drug targeting efficiency, 75.26% nose-to-brain direct transport percentage, and 4.06 drug targeting index of the dual-optimized formulation were significantly higher than those of the raw MTC-loaded ISG formulation. The performance of the dual-optimized PEG-T-Chito-Lip nano-vesicular hybrids for intranasal administration evidenced MTC-improved bioavailability, circumvented hepatic metabolism, and enhanced brain targetability, with increased potentiality in heightening the convenience and compliance for patients.

Abstract
Piperine (PPN) is a natural alkaloid derived from black pepper (Piper nigrum L.) and has garnered substantial attention for its potential in breast cancer therapy due to its diverse pharmacological properties. However, its highly lipophilic characteristics and poor dissolution in biological fluids limit its clinical application. Therefore, to overcome this limitation, we formulate and evaluate PPN-encapsulated polycaprolactone (PCL) nanoparticles (PPN-PCL-NPs). The nanoparticles were prepared by a single-step nanoprecipitation method and further optimized by a formulation design approach. The influence of selected independent variables PCL (X1), poloxamer 188 (P-188; X2), and stirring speed (SS; X3) were investigated on the particle size (PS), polydispersity index (PDI), and % encapsulation efficiency (EE). The selected optimized nanoparticles were further assessed for stability, in vitro release, and in vitro antibreast cancer activity in the MCF-7 cancer cell line. The PS, PDI, zeta potential, and % EE of the optimized PPN-PCL-NPs were observed to be 107.61 ± 5.28 nm, 0.136 ± 0.011, -20.42 ± 1.82 mV, and 79.53 ± 5.22%, respectively. The developed PPN-PCL-NPs were stable under different temperature conditions with insignificant changes in their pharmaceutical attributes. The optimized PPN-PCL-NPs showed a burst release for the first 6 h and later showed sustained release for 48 h. The PPN-PCL-NPs exhibit exceptional cytotoxic effects in MCF-7 breast tumor cells in comparison with the native PPN. Thus, the formulation of PPN-loaded PCL-NPs can be a promising approach for better therapeutic efficacy against breast cancer.

Abstract
Here, we evaluate the feasibility of co-loading plain ranitidine hydrochloride (RHCl) and microencapsulated flurbiprofen (FBP) in a Lycoat® RS780-based oral fast disintegrating film (ODF). These films were developed by the solvent casting method to minimize the adverse effects of FBP and reduce the dosage form burden on patients. Optimized FBP microparticles (M3) with an average size of 21.2 ± 9.2 µm were loaded alone (F1) and in combination with plain RHCl (F2) in the composite ODF. All films were evaluated physicomechanically and physicochemically. These films were resilient, flexible, and disintegrated within thirty seconds. SEM images showed intact FBP microparticles in both formulations and, moreover, did not observe an interaction between the drug and film components. Microencapsulated FBP was released in a controlled manner over 48 h from the proposed formulations, while RHCl was released within 5 min from F2. After in vitro evaluation, formulations were also tested for in vivo anti-inflammatory activity, cytokine (TNF-α and IL-6) levels, and gastroprotective effects in rats. The anti-inflammatory activity and gastroprotective effect of F2 were markedly higher than pure FBP and other synthesized formulations (M3 and F1). The average score of gastric lesions was in the order of pure FBP (15.5 ± 1.32) > M3 (8 ± 2) > F1 (1 ± 0.5) > F2 (0.5 ± 0) > control (0). Additionally, F2 showed a sustained anti-inflammatory effect up to 10 h in the rat paw edema model. Furthermore, F2 also markedly reduced TNF-α and IL-6 levels. Conclusively, the Lycoat® RS780-based composite film could be a promising carrier for the co-loading of microencapsulated FBP with RHCl. In the future, an optimized formulation (F2) could be capable of countering the issues related to multiple drug administration in geriatric patients and evading the gastric irritation associated with FBP.

Polymers (Basel) 2023; 15:2844. [PMID: 37447489 DOI: 10.3390/polym15132844] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 06/21/2023] [Accepted: 06/23/2023] [Indexed: 07/15/2023] Open
Abstract
Ribociclib is a newly approved orally administered drug for breast cancer. This study aimed to prepare, characterize, and evaluate hybrid lipid-polymer nanoparticles (PLNs) of ribociclib to enhance its in vitro dissolution rate, pharmacokinetics, and anticancer efficacy. Ribociclib-loaded PLNs were prepared by solvent evaporation using the Box-Behnken design to optimize formulation variables. Particle size, entrapment efficiency, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FTIR), atomic force microscopy (AFM), in vitro release cytotoxicity, molecular modeling, and pharmacokinetic studies were examined. The ribociclib-loaded PLN (formula 1, F1) was optimized in terms of particle size (266.9 ± 4.61 nm) and encapsulation efficiency (59.1 ± 2.57 mg/mL). DSC and thermogravimetric characterization showed the absence of a crystalline structure in the prepared PLNs, confirmed by FTIR, and showed no interactions between the components and the drug. AFM showed well-dispersed heterogeneously shaped nanoparticles. The in vitro release profile exhibited significant results for the optimized formula, reaching 100% at 600 and 90 min at pH 6.8 and 1.2, respectively. The low IC50 obtained by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay suggests that optimized PLN might serve as an effective delivery vehicle for cancer treatment, especially breast and lung cancer. Molecular modeling revealed several hydrogen bonds. A pharmacokinetic study in rats showed that the ribociclib formula had a 6.5-fold increase in maximum concentration (Cmax) and a 5.6-fold increase in area under the curve (AUC). Regarding the everted intestinal sac absorption, formula 1 increased ribociclib penetration relative to the physical combination and pure medication. In conclusion, optimized PLNs with enhanced physicochemical and cytotoxic properties and improved pharmacokinetic parameters were successfully prepared.

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.

Abstract
Onychomycosis is a nail infection caused by a fungus, Trichophyton mentagrophytes, that is responsible for major nail infections. The best method suited for treating such infections generally includes a topical remedy. However, conventional oral or topical formulations are associated with various limitations. Therefore, a more efficient and compatible formulation is developed in this study. The primary objective of the current study is to formulate and evaluate chitosan nanoparticle-based hydrogel for ameliorating onychomycosis. The sole purpose of this research was to increase the permeation of the lipophilic drug itraconazole and difluorinated curcumin, and its synergistic antifungal activity was also evaluated for the first time. Both in vitro and ex vivo drug release evaluations confirmed the sustained release of both drugs from the hydrogel, which is a prerequisite for treating onychomycosis. The results overall highlighted the promising activity of a synergistic approach that could be implemented for the treatment of onychomycosis. The hydrogel-based formulation serves as an effective method of delivery of drugs across the layers of the skin, resulting from its hydrating characteristics.

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
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
Acyclovir (ACR) is considered the gold standard drug for the treatment of skin viral infections caused by the herpes simplex or varicella-zoster virus. However, topical therapy with ACR is hindered by its poor skin penetrability, thus necessitating high doses and frequent administrations. This study was proposed to formulate a modified lipid-coated chitosan nanocomplexes (LCNCs) of acyclovir (ACR), containing span 80 and TPGS, to boost the dermal delivery of ACR and improve the therapeutic outcomes. LCNCs were formulated through a self-assembly method, and the statistical analysis and the optimization were performed via a general 23 factorial design. Three formulation variables were selected; namely, the amount of chitosan (A), the amount of glyceryl monooleate (GMO) (B), and span 80: D-α-tocopheryl polyethylene glycol succinate (Vitamin ETPGSorTPGS) ratio (C). Four measured attributes were determined; viz., the particle size (PS) in nm, the polydispersity index (PDI), the zeta potential (ZP) in mV, and the entrapment efficiency percentages (EE%). The optimal formulation (LCNCs 8), formulated with 600 mg chitosan, 120 mg GMO, and 3:1 span 80: TPGS ratio, possessed PS of 177.50 ± 1.41 nm, PDI value of 0.28 ± 0.02, ZP of -10.70 ± 0.85 mV, and EE% of 77.20 ± 2.40 %, and was able to sustain ACR release over 24 h. Transmission electron microscopy displayed LCNCs architecture as a polymeric core of chitosan with a lipid coat of GMO, and the solid-state characterization results confirmed the dispersion of ACR in LCNCs. The ex vivo permeation study and the in vivo dermatokinetics profile verified the boosted accumulation of ACR in the skin via LCNCs, while the confocal laser scanning microscopy revealed the heightened penetrability of LCNCs. The topical application of LCNCs demonstrated a safe profile via the modified Draize test and histopathological examinations. Inclusively, ACR-loaded LCNCs could be a promising topical formulation with an advanced dermal delivery status for the treatment of skin viral infections.

Abstract
There is a curious case in Alveolar macrophages (AM), the frontline defence recruits that contain the spread of all intruding bacteria. In response to Mycobacterium tuberculosis (M.tb), AM either contain the spread or are modulated by M.tb to create a region for their replication. The M.tb containing granulomas so formed are organised structures with confined boundaries. The limited availability of drugs inside AM aid drug tolerance and poor therapeutic outcomes in diseases like tuberculosis. The present work proves the glycotargeting efficiency of levofloxacin (LVF) to AM. The optimised formulation developed displayed good safety with 2% hemolysis and a viability of 61.14% on J774A.1 cells. The physicochemical characterisations such as Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) proved that carubinose linkage was accomplished and LVF is entrapped inside carubinose-linked hybrid formulation (CHF) and hybrid formulation (HF) in amorphous form. The transmission electron microscopy (TEM) images revealed a core-shell structure of HF. The particle size of 471.5 nm estimated through dynamic light scattering (DLS) is enough to achieve active and passive targeting to AM. The nanoparticle tracking analysis (NTA) data revealed that the diluted samples were free from aggregates. Fluorescence-activated cell sorting (FACS) data exhibited excellent uptake via CHF (15 times) and HF(3 times) with reference to plain fluorescein isothiocyanate (FITC). The pharmacokinetic studies revealed that CHF and HF release the entrapped moiety LVF in a controlled manner over 72 h. The stability studies indicated that the modified formulation remains stable over 6 months at 5 ± 3℃. Hence, hybrid systems can be efficiently modified via carubinose to target AM via the parenteral route.

The Physicochemical, Biopharmaceutical, and In Vitro Efficacy Properties of Freeze-Dried Dexamethasone-Loaded Lipomers. Pharmaceutics 2021; 13:pharmaceutics13081322. [PMID: 34452283 PMCID: PMC8401638 DOI: 10.3390/pharmaceutics13081322] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 08/16/2021] [Accepted: 08/17/2021] [Indexed: 11/17/2022] Open
Abstract
Dexamethasone-loaded polymer hybrid nanoparticles were developed as a potential tool to treat alopecia areata due to their follicular targeting ability. Freeze drying (FD) is a common technique used to improve nanoparticle stability; however, there are few studies focused on its effect on ethyl cellulose lipid-core nanoparticles. Nanoparticles were lyophilized with different cryoprotectants. Sucrose was selected because it allowed for a good resuspension and provided acceptable physicochemical parameters (374.33 nm, +34.7 mV, polydispersion 0.229%, and 98.87% encapsulation efficiency). The nanoparticles obtained were loaded into a pleasant xanthan gum hydrogel, and the rheological, release, and skin permeation profiles of different formulations were studied. The FD formulation significantly modified the particle size, and the drug release and permeation properties were also altered. In addition, analyses of the cytotoxicity and anti-inflammatory efficacy of FD and non-FD particles on human keratinocytes indicated no differences.

Pulmonary Delivery of Anticancer Drugs via Lipid-Based Nanocarriers for the Treatment of Lung Cancer: An Update. Pharmaceuticals (Basel) 2021; 14:725.

Abstract
Lung cancer (LC) is the leading cause of cancer-related deaths, responsible for approximately 18.4% of all cancer mortalities in both sexes combined. The use of systemic therapeutics remains one of the primary treatments for LC. However, the therapeutic efficacy of these agents is limited due to their associated severe adverse effects, systemic toxicity and poor selectivity. In contrast, pulmonary delivery of anticancer drugs can provide many advantages over conventional routes. The inhalation route allows the direct delivery of chemotherapeutic agents to the target LC cells with high local concertation that may enhance the antitumor activity and lead to lower dosing and fewer systemic toxicities. Nevertheless, this route faces by many physiological barriers and technological challenges that may significantly affect the lung deposition, retention, and efficacy of anticancer drugs. The use of lipid-based nanocarriers could potentially overcome these problems owing to their unique characteristics, such as the ability to entrap drugs with various physicochemical properties, and their enhanced permeability and retention (EPR) effect for passive targeting. Besides, they can be functionalized with different targeting moieties for active targeting. This article highlights the physiological, physicochemical, and technological considerations for efficient inhalable anticancer delivery using lipid-based nanocarriers and their cutting-edge role in LC treatment.

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.

Molecules 2021; 26:molecules26092690. [PMID: 34064416 PMCID: PMC8125698 DOI: 10.3390/molecules26092690] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 04/24/2021] [Accepted: 05/01/2021] [Indexed: 11/29/2022] Open
Abstract
The objective of this study was to synthesize and characterize a set of biodegradable block copolymers based on TPGS-block-poly(ε-caprolactone) (TPGS-b-PCL) and to assess their self-assembled structures as a nanodelivery system for paclitaxel (PAX). The conjugation of PCL to TPGS was hypothesized to increase the stability and the drug solubilization characteristics of TPGS micelles. TPGS-b-PCL copolymer with various PCL/TPGS ratios were synthesized via ring opening bulk polymerization of ε-caprolactone using TPGS, with different molecular weights of PEG (1–5 kDa), as initiators and stannous octoate as a catalyst. The synthesized copolymers were characterized using 1H NMR, GPC, FTIR, XRD, and DSC. Assembly of block copolymers was achieved via the cosolvent evaporation method. The self-assembled structures were characterized for their size, polydispersity, and CMC using dynamic light scattering (DLS) technique. The results from the spectroscopic and thermal analyses confirmed the successful synthesis of the copolymers. Only copolymers that consisted of TPGS with PEG molecular weights ≥ 2000 Da were able to self-assemble and form nanocarriers of ≤200 nm in diameter. Moreover, TPGS2000-b-PCL4000, TPGS3500-b-PCL7000, and TPGS5000-b-PCL15000 micelles enhanced the aqueous solubility of PAX from 0.3 µg/mL up to 88.4 ug/mL in TPGS5000-b-PCL15000. Of the abovementioned micellar formulations, TPGS5000-b-PCL15000 showed the slowest in vitro release of PAX. Specifically, the PAX-loaded TPGS5000-b-PCL15000 micellar formulation showed less than 10% drug release within the first 12 h, and around 36% cumulative drug release within 72 h compared to 61% and 100% PAX release, respectively, from the commercially available formulation (Ebetaxel®) at the same time points. Our results point to a great potential for TPGS-b-PCL micelles to efficiently solubilize and control the release of PAX.

Abstract
Background
There are many circumstances where chronic disease is associated with other disorders, especially in diseases such as diabetes with noncommunicable disease risk factors, such as hypertension. The current therapies for treating such chronic comorbid diseases are limited and challenging due to the difficulties in overcoming the side effects from complex therapeutic treatment regimen. The present study is aimed to develop and optimize the combinational nano invasomal gel of Glibenclamide (GLB) and Atenolol (ATN) as a novel combination therapy for comorbid treatment of diabetic hypertensive patients. The developed formulations were characterized for various parameters, including in-vitro skin permeation, skin irritation, in-vivo antidiabetic, and antihypertensive activities.
Results
OCNIG showed that the % entrapment efficiency of GLB is 96.67 ± 0.65% and % entrapment efficiency of ATN is 93.76 ± 0.89%, flux of GLB (240.43 ± 1.76 μg/cm2/h), and flux of ATN (475.2 ± 1.54 μg/cm2/h) which was found to conform to the expected value. The results indicated desired release and permeation profiles. Optimized formulation showed significant pharmacokinetic properties, which shows improvement in bioavailability by 134.30% and 180.32% respectively for two drugs, when compared to marketed oral preparation. Pharmacodynamic studies showed improved and prolonged management of diabetes and hypertension in Wistar rats, compared to oral and drug-loaded nano invasomes formulations.
Conclusion
Overall, the results showed that nano invasomal gel was found to be a useful and promising transdermal delivery system for the treatment of concurrent diseases.

Abstract
This study investigated the feasibility of lipid polymer hybrid nanoparticles (LPH) as a platform for the combinatorial delivery of small interfering RNA (siRNA) and etoposide (Eto). Different Eto loaded LPH formulations (LPH Eto ) are prepared. The optimized cationic LPH Eto with a particle size of 109.66 ± 5.17 nm and Eto entrapment efficiency (EE %) of 80.33 ± 2.55 is used to incorporate siRNA targeting CD47 (siCD47), a do not eat me marker on the surface of cancer cells. The siRNA-encapsulating LPH (LPH siNEG-Eto ) has a particle size of 115.9 ± 4.11 nm and siRNA EE % of 63.54 ± 4.36 %. LPHs improved the cellular uptake of siRNA in a dose- and concentration-dependent manner. Enhanced cytotoxicity (3.8-fold higher than Eto solution) and high siRNA transfection efficiency (≈50 %) are obtained. An in vivo biodistribution study showed a preferential uptake of the nanosystem into lung, liver, and spleen. In an experimental pseudo-metastatic B16F10 lung tumor model, a superior therapeutic outcome can be observed in mice treated with combinatory therapy. Immunological studies revealed elevated CD4+, CD8+ cells, and macrophages in the lung following combinatory treatment. The study suggests the potential of the current system for combinatory chemotherapy and immunotherapy for the treatment of lung cancer or lung metastasis.

Abstract
The development of controlled-release drug delivery systems has a great potential to improve the efficacy of anticancer drugs. This study aimed to develop and optimize the production of hybrid lipid-polymer nanoparticles (HLPNPs) for the targeted delivery of melphalan anticancer drugs. Response surface methodology (RSM) and central composite design (CCD) were used to evaluate and optimize the effects of three independent variables including lipid, polymer, and polyvinyl alcohol (PVA) ratios on the nanoparticles (NPs) size and drug entrapment efficiency (EE%). Hybrid NPs were prepared using the nanoprecipitation method. The results demonstrated that spherical NPs were synthesized, and the rate of EE% went up by increasing the polymer as well as decreasing the PVA concentrations. The nanoformulation released melphalan in a sustained and controlled manner (17.39% in a period time of 48 h). Also, cytotoxicity evaluations showed that HLPNPs caused an increase in the efficacy of melphalan against human ovarian A2780CP and SKOV3 cancer cells. Overall, the results of this study demonstrated that HLPNPs can be considered as a promising carrier for the delivery of hydrophobic anticancer drugs such as melphalan and the evaluation in-vivo.

Abstract
Nanostructured colloidal self-assembly (NCS) is one of the most promising drug delivery carriers in cancer treatment. The present research work aimed towards synthesizing meloxicam (MLX) loaded NCS for its improved circulation half-life and increased cellular internalization. NCS was formulated using glyceryl monoolein, Pluronic® F127, and MLX. Quality by Design experiments with a quadratic model was subjected to optimization of the formulation. The optimized NCS with an average particle size of 185.5 ± 3.02 nm showed higher MLX encapsulation (94.74 ± 3.41%) and sustained release behavior of MLX up to 24 hr. in vitro cytotoxicity of the developed NCS with MCF-7 and MDA-MB-231 cell lines confirmed lower cell viability and a higher rate of cell growth inhibition. This MLX loaded NCS showed dual activity as an antitumor and anti-inflammatory in highly invasive estrogen-dependent MDA-MB-231 cells due to the high expression of cyclooxygenase-2 (COX-2). Besides, an activity of the MLX-NCS was also observed in 3D printed MCF-7 cells. This investigation shows the possible use of MLX-NCS as an efficient cancer drug delivery system with excellent colloidal stability, sustained release of MLX, enhanced antitumor and anti-inflammatory efficacy in 3D printed scaffolds. In contrast to toxicity study in 2D culture, the 3D constructs revealed the activity of the MLX via COX-2 independent mechanism and demonstrated that the relationship between COX-2 expression and antitumor activity of inhibitors is limited. In conclusion, the overall observations and results of this study strengthen the hypothesized development of NCS as a next-generation therapeutics regimen for cancer therapy.

Abstract
Itraconazole is a triazole drug widely used in the treatment of fungal infections, and it is in clinical trials for treatment of several cancers. However, the drug suffers from poor solubility, while experiments have shown that itraconazole delivery in liposome nanocarriers improves both circulation half-life and tissue distribution. The drug release mechanism from the nanocarrier is still unknown, and it depends on several factors including membrane stability against defect formation. In this work, we used molecular dynamics simulations and potential of mean force (PMF) calculations to quantify the influence of itraconazole on pore formation over lipid membranes, and we compared the effect by itraconazole with a pore-stabilizing effect by the organic solvent dimethyl sulfoxide (DMSO). According to the PMFs, both itraconazole and DMSO greatly reduce the free energy of pore formation, by up to ∼20 kJ mol-1. However, whereas large concentrations of itraconazole of 8 mol % (relative to lipid) were required, only small concentrations of a few mole % DMSO (relative to water) were sufficient to stabilize pores. In addition, itraconazole and DMSO facilitate pore formation by different mechanisms. Whereas itraconazole predominantly aids the formation of a partial defect with a locally thinned membrane, DMSO mainly stabilizes a transmembrane water needle by shielding it from the hydrophobic core. Notably, the two distinct mechanisms act cooperatively upon adding both itraconazole and DMSO to the membrane, as revealed by an additional reduction of the pore free energy. Overall, our simulations reveal molecular mechanisms and free energies of membrane pore formation by small molecules. We suggest that the stabilization of a locally thinned membrane as well as the shielding of a transmembrane water needle from the hydrophobic membrane core may be a general mechanism by which amphiphilic molecules facilitate pore formation over lipid membranes at sufficient concentrations.

Abstract
PURPOSE Gallic acid (GA) is a polyphenolic compound with proven efficacy against hepatic fibrosis in experimental animals. However, it suffers from poor bioavailability and rapid clearance that hinders its clinical investigation. Accordingly, we designed and optimized reverse micelle-loaded lipid nanocapsules (RMLNC) using Box-Behnken design that can deliver GA directly into activated-hepatic stellate cells (aHSCs) aiming to suppress hepatic fibrosis progression. METHODS GA-RMLNC was prepared using soft energy, solvent free phase inversion temperature method. Effects of formulation variables on particle size, zeta potential, entrapment efficiency (EE%) and GA release were studied. In-vivo biodistribution of GA-RMLNC in rats and in-vitro activities on aHSCs were also explored. RESULTS Nano-sized GA-RMLNCs (30.35 ± 2.34 nm) were formulated with high GA-EE% (63.95 ± 2.98% w/w) and physical stability (9 months). The formulated system showed burst GA release in the first 2 h followed by sustained release profile. In-vivo biodistribution imaging revealed that RMLNC-loaded with rhodamine-B accumulated mainly in rats' livers. Relative to GA; GA-RMLNC displayed higher anti-proliferative activities, effective internalization into aHSCs, marked down-regulation in pro-fibrogenic biomarkers' expressions and elevated HSCs' apoptosis. CONCLUSIONS These findings emphasize the promising application of RMLNC as a delivery system in hepatic fibrosis treatment, where successful delivery of GA into aHSCs was ensured via increased cellular uptake and antifibrotic activities.

Abstract
Vulvovaginal candidiasis is a serious health problem affecting numerous women around the world. Its treatment is based on antifungals which may not provide an effective cure because of the resistance presented by its etiological pathogens Candida spp. Candida albicans is the most prevalent species related to vulvovaginal candidiasis. Here, we evaluated the in vivo antifungal potential of thiosemicarbazide and thiosemicarbazide encapsulated within chitosan nanoparticles in a murine model of vulvovaginal candidiasis. The results demonstrated the antifungal capacity of free or nanoencapsulated thiosemicarbazide within chitosan to reduce the fungal load in the vaginal tissue of infected mice. In addition, histological analyses indicated the absence or a mild to moderate infection in thiosemicarbazide-treated groups. Statistical tests confirmed the existence of significant differences between the treated and the control groups. Therefore, our results suggest a potential application of thiosemicarbazide and encapsulated thiosemicarbazide as an alternative vulvovaginal candidiasis therapy.

Long-Acting Paliperidone Parenteral Formulations Based on Polycaprolactone Nanoparticles; the Influence of Stabilizer and Chitosan on In Vitro Release, Protein Adsorption, and Cytotoxicity. Pharmaceutics 2020; 12:E160.

Abstract
Long-acting preparations containing the antipsychotic paliperidone for intramuscular injection has drawn considerable attention to achieve harmless long-term treatment. This study aimed to develop paliperidone loaded polycaprolactone (PCL) nanoparticles and investigate the influence of PCL/drug ratio, stabilizer type, and chitosan coating on physicochemical properties, protein adsorption, and cellular toxicity. Results showed that chitosan coating produced enlarged particle sizes, shifted the surface charges from negative into positive and did not influence encapsulation efficiencies. Chitosan coating relatively sustained the drug release especially in pluronic stabilized formulations. Pluronic F127 based formulations exhibited the least protein adsorption (384.3 μg/mL). Chitosan coating of Tween 80 and polyvinyl alcohol stabilized formulations significantly (p < 0.05) increased protein adsorption. Cellular viability was concentration-dependent and negatively affected by stabilizers. All formulations did not show cellular death at 1.56 μg/mL. Inflammatory responses and oxidative stress were less affected by Tween 80 compared with other stabilizers. Chitosan minimized all aspects of cellular toxicity. Collectively, stabilizer type and chitosan coating play critical roles in developing safe and effective long-acting PCL nanoparticles intended for parenteral drug delivery. The coated formulations containing Tween 80 and Pluronic F127 as stabilizers are warranted a future in vivo study to delineate its safety and efficacy profiles.

Abstract
Objective:
The objective of this study was to entrap water-insoluble drug itraconazole
into polymer to form drug entrapped nanoparticles by using simple formulation strategy and characterize
them for various in vitro properties.
Method:
Itraconazole (ITZ) encapsulated Eudragit E 100 nanoparticles (IEENs) were formulated by
emulsification solvent evaporation technique.
Results:
Developed IEENs were evaluated for entrapment efficiency, particle size, polydispersity
index, and drug release profile. It was clear that drug polymer ratio along with homogenization
speed are the factors affecting droplet size of an emulsion. Evaluation was done by HPLC at
263nm. DSC, XRD studies were carried out. The in vitro antifungal study of nanoparticles suggested
that they are more effective in inhibiting growth of Candida albicans.
Conclusion:
The results from this study suggest the potential use of IEENs to provide a possible
way of improving solubility and thus oral absorption of Itraconazole. Thus the study concluded that
IEENs have potential to effectively treat the fungal infection.

Abstract
This study presents an alternative therapy to conventional anti-Parkinson's treatment strategies; where motor and non-motor symptomatic complications are considered. Thus; providing sustainability, patient compliance, therapeutic safety and efficiency, based on triggering secretion of endogenous dopamine (DA). Exogenous DA has long been considered the best therapy, however, its poor blood brain barrier (BBB) permeability, fluctuated plasma levels, and non-motor complications negligence, decreased response to therapy with time. Consequently; brain targeting Tween®80-coated pegylated lipomers were tailored for intravenous administration (IV) of L-Dopa, and two drugs of reported neuroprotective effect: lamotrigine (LTG) and tenoxicam (TX). Single-step nanoprecipitation method was used; for its reproducibility and ease of scaling-up. Formulation targeting and anti-PD efficiency was evaluated against marketed standards and L-Dopa. In-vitro and in-vivo pharmacokinetic and dynamic studies were carried out for setting optimization standards upon varying inter-components ratio. Results revealed that lipomers are, generally, significantly efficient in brain targeting compared to oral tablets. LTG-lipomers (LF20) showed the maximum anti-PD compared to its TX and L-Dopa analogues. Combining LTG and TX had synergistic effect; highlighting a new prescription for both drugs. Thus; offering a safe, targeted, and therapeutically efficient sustained dosage form, capable of mitigating PD risk and treating it though weekly administration. Hence; presenting a novel promising anti-neurodegenerative strategy; on employing various mechanisms that were previously achieved through additional therapeutic supplements.

Abstract
Background:
Gefitinib (GEF), the kinase inhibitor, is presently available as tablets to be taken orally in high doses of 250-500 mg per day due to its poor solubility. The solubility issues affect not only its onset of action but also the bioavailability. These drawbacks foresight the need to have an alternate dosage form, preferably a sustained release formulation.
Methods:
In the present study, microparticles were prepared by emulsion solvent evaporation using PLGA 50:50 (GEF-PLGA MP). A 32 factorial design was used to optimize the critical quality parameters to the set mean particle size in the range of 7.4±2.5 µm and entrapment efficiency of 80%. SEM microscopy of the prepared microparticles confirmed to have a spherical smooth shape. The GEFPLGA- MPs sustained the release of GEF for 72 hours. The first-order kinetics ruled the mechanism of drug release and was predicted to follow Fickian diffusion.
Result:
Anticancer efficacy was judged by the cytotoxicity studies using the L132 lung cancer cells. MTT assay showed 3-fold enhanced cytotoxicity of GEF loaded microparticles against L132 cells as compared to plain GEF.
Conclusion:
It was concluded that gefitinib can be efficiently loaded into the biodegradable polymer PLGA to provide sustained release of the drug.

Abstract
Itraconazole (ITZ) loaded Poly-(D, L-lactic-co-glycolic acid, PLGA) nanoparticles (PLGA-NPs) stabilized by D-α-Tocopherol polyethylene-glycol succinate-1000 (TPGS) were developed by nanoprecipitation and single emulsion solvent evaporation methods to improve antifungal activity of ITZ by enhancing its solubility, and hence bioavailability. Encapsulation efficiency, drug loading, in-vitro release, ex-vivo permeation and antifungal activity were performed for the optimized PLGA-NPs. Characterization of PLGA-NPs were performed by scanning electron microscopy, dynamic light scattering, differential scanning calorimetry, Fourier transform infrared spectroscopy, and powder X-ray diffractometry. We observed that nanoprecipitation method was more efficient in encapsulating ITZ by using 0.3% TPGS (stabilizer) than single emulsion solvent evaporation method. Our thermal analysis studies showed no characteristic peaks for crystalline ITZ, indicating drug efficiently encapsulated inside the nanoparticle with no compatibility issues. Drug loaded PLGA-NPs preserved the antifungal activity of ITZ against Candida albicans. Drug release profile from the NPs showed an initial burst release followed by an extended release phase suggesting the potential of NPs for sustained release applications. Furthermore, ITZ encapsulated in PLGA-NPs showed enhanced intestinal permeability in the ex-vivo study. In conclusion, the developed nano-system successfully encapsulated ITZ, yielding an increased permeation and consequential antifungal activity.

Abstract
Localized cancer rates are on an upsurge, severely affecting mankind across the globe. Timely diagnosis and adopting appropriate treatment strategies could improve the quality of life significantly reducing the mortality and morbidity rates. Recently, nanotherapeutics has precipitously shown increased efficacy for controlling abnormal tissue growth in certain sites in the body, among which ligand functionalized nanoparticles (NP) have caught much attention for improved survival statistics via active targeting. Our focus was to repurpose the antihelminthic drug, niclosamide (NIC), which could aid in inhibiting the abnormal growth of cells restricted to a specific region. The work here presents a one-pot synthesis of niclosamide encapsulated, hyaluronic acid functionalized core–shell nanocarriers [(NIC-PLGA NP)HA] for active targeting of localized cancer. The synthesized nanocarriers were found to possess spherical morphology with mean size of 150.8 ± 9 nm and zeta potential of −24.9 ± 7.21 mV. The encapsulation efficiency was found to be 79.19 ± 0.16% with a loading efficiency of 7.19 ± 0.01%. The nanohybrids exhibited extreme cytocompatibility upon testing with MDA-MB-231 and L929 cell lines. The rate of cancer cell elimination was approximately 85% with targeted cell imaging results being highly convincing. [(NIC-PLGA NP)HA] demonstrates increased cellular uptake leading to a hike in reactive oxygen species (ROS) generation, combating tumour cells aiding in the localized treatment of cancer and associated therapy. Localized binding of nanoparticulate formulation, actively targeting the receptors present on the cell surface.![]()

Abstract
Self-assembled nanocarriers (SANs) as a novel colloidal controlled delivery for docetaxel trihydrate (DTX) were engineered by high-pressure homogenization method to overcome the several clinical problems. Drug-excipient compatibility was studied using DSC and FTIR spectroscopy. The fabricated SANs was characterized by particle size, zeta potential, and SEM. QbD based central composite design of experiment was employed for formula optimization. The cell viability of DTX-hydroalcoholic solution (DTX-HA) and DTX-loaded SANs has been determined in MDA-MB-231 cell line by MTT assay. The stability study of selected SANs formulations were carried out at various storage conditions as per ICH guidelines. The summary of results obtained shows high drug content with higher entrapment efficiency (91.23 ± 3.41% w/w) of DTX-loaded SANs. It shows diffusion controlled release of DTX over the period of 12 h which is higher than DTX-HA solution, releases the DTX within 4 h. The MTT assay expressed lower cellular viability and improved cell inhibition leads to increase cytotoxicity of formulations towards cells. The stability study reveals stability of DTX-loaded SANs formulations at various storage conditions over a period of three months. The strong experimental evidence confirms the SANs as an effective approach to formulate the controlled delivery system of antineoplastics with improved stability.

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.

[PMID: 27863658 DOI: 10.1016/j.ijpharm.2016.07.053] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2016] [Revised: 07/21/2016] [Accepted: 07/23/2016] [Indexed: 12/11/2022]
Abstract
This article reviews the field of oral uptake of nanoparticles across the gastrointestinal epithelium for the period 2006-2016. Analysis is conducted from the viewpoint of i) M-cell genetics and model development, ii) drug targeting to Peyer's patches and M-cells, and iii) physicochemical interactions of nanoparticles in the intestinal milieu. In light of these recent developments, regulatory considerations in the development of orally-absorbable nanoparticle drug products are discussed and focused on Module 3.2.P sub-sections of the Common Technical Document. Particular attention is paid to novel excipients, ligands and the non-standard method of manufacture. The novelty of this drug delivery system demands not only a multi-disciplinary scientific and regulatory approach but also a risk-adjusted consideration for a system defined by both processes and specifications. Given the current state of scientific development in the field it is suggested (in the author's personal opinion) that the design of nanoparticulate drug delivery systems should be kept as simple as possible (from a regulatory and manufacturing perspective) and to target the entire gastrointestinal epithelium.

Abstract
PURPOSE This study was undertaken to evaluate the biopharmaceutical properties of cyclosporine A (CsA)-loaded nano-matrix particles for inhalation. METHODS Nano-matrix particles of CsA with mannitol (nCsAm) were prepared by a flash nano-precipitation technique employing a multi-inlet vortex mixer and evaluated in terms of physicochemical properties, anti-inflammatory effect in the rat model of airway inflammation, pharmacokinetic behavior, and distributions of CsA to side-effect-related organs after intratracheal administration. RESULTS In nCsAm, spherical nano-particles of CsA were covered with mannitol and the mean particle size was 1.3 μm. The in vitro Next Generation Impactor analysis demonstrated fine inhalation performance with a fine particle fraction value of 65.8%. Intratracheal nCsAm (100 μg-CsA/rat) significantly attenuated the recruitment of inflammatory cells into the airway in the rat model of airway inflammation, followed by suppression of the inflammatory biomarkers. After intratracheal nCsAm at a pharmacologically effective dose (100 μg-CsA/rat), there was a 42-47-fold decrease in the distribution of CsA to side-effect-related organs such as the kidney and liver compared with oral CsA at a toxic dose (10 mg-CsA/kg), potentially leading to avoidance of systemic side-effects of CsA. CONCLUSION Upon these findings, nCsAm prepared with the flash nano-precipitation technique could be a novel dosage form of CsA for inhalation therapy of airway inflammation with a better safety margin.

Abstract
CONTEXT Lipid-polymer hybrid nanoparticles (LPNPs) are polymeric nanoparticles enveloped by lipid layers, which have emerged as a potent therapeutic nanocarrier alternative to liposomes and polymeric nanoparticles. OBJECTIVE The aim of this work was to develop, characterize and evaluate LPNPs to deliver a model protein, lysozyme. MATERIALS AND METHODS Lysozyme-loaded LPNPs were prepared by using the modified w/o/w double-emulsion-solvent-evaporation method. Poly-ɛ-caprolactone (PCL) was used as polymeric core material and tripalmitin:lechitin mixture was used to form a lipid shell around the LPNPs. LPNPs were evaluated for particle size distribution, zeta potential, morphology, encapsulation efficiency, in vitro drug release, stability and cytotoxicity. RESULTS The DLS measurement results showed that the particle size of LPNPs ranged from 58.04 ± 1.95 nm to 2009.00 ± 0.52 nm. The AFM and TEM images of LPNPs demonstrate that LPNPs are spherical in shape. The protein-loading capacity of LPNPs ranged from 5.81% to 60.32%, depending on the formulation parameters. LPNPs displayed a biphasic drug release pattern with a burst release within 1 h, followed by sustained release afterward. Colloidal stability results of LPNPs in different media showed that particle size and zeta potential values of particles did not change significantly in all media except of FBS 100% for 120 h. Finally, the results of a cellular uptake study showed that LPNPs were significantly taken up by 83.3% in L929 cells. CONCLUSION We concluded that the LPNPs prepared with PCL as polymeric core material and tripalmitin:lechitin mixture as lipid shell should be a promising choice for protein delivery.

Abstract
Novel catanionic lipid nanosystems (CLNs) incorporating curcumin (CCM) were developed, and improvements in pharmacokinetics and enhanced anti-lung cancer activity were observed. CCM was present in a lipid matrix surrounded by cationic, anionic and zwitterionic surfactants, forming the core-shell nanosystems. Compared with free CCM, the CCM-CLNs had much higher oral and intravenous bioavailabilities due to enhanced absorption and reduced clearance. The CCM-CLNs exhibited greater cytotoxicity in Lewis lung cancer (LLC) cells, which might have been due to increased antiproliferative, proapoptotic and anti-invasive activities and induction of cell cycle arrest. The CCM-CLNs increased the antitumor efficacy of CCM and decreased the tumor growth rate in tumor-bearing mice. This is the first report of induction of apoptosis in LLC cells by CCM through the PI3K/Akt/FoxO1/Bim signaling pathway. Catanionic lipid nanocarriers show promise for the therapeutic delivery of insoluble anti-tumor drugs.
