Abstract
α-Bisabolol (αBIS), a plant-derived compound with anti-inflammatory properties, is potentially a therapeutic agent for Atopic dermatitis. However, its poor water solubility and photoinstability limit its topical application. Therefore, the present study, aimed to develop cationic polymeric nanocapsules of αBIS to improve its skin delivery, photostability, and therapeutic efficacy. The αBIS-loaded nanocapsules were prepared using the solvent displacement technique. A Box-Behnken (BB) design was employed to statistically optimize formulation variables and αBIS-loaded nanocapsules characterized by particle size, surface charge and encapsulation efficiency. The optimal formulation was selected, and the spherical shape of the nanocapsules was confirmed by scanning electron microscopy (SEM). Furthermore, hydrogel containing αBIS-loaded nanocapsules was prepared by thickening of nanocapsule suspension with Carbopol 934 and evaluated for rheology, in vitro drug release and skin permeation. Furthermore, a mice model of atopic dermatitis was used to evaluate the anti-inflammatory potential of the hydrogels. The optimal formulation displayed a spherical morphology under scanning electron microscopy (SEM) with an optimum particle size of 133.00 nm, polydispersity index (PDI) of 0.12, high EE% of 93 %, and improved optical stability of αBIS in the prepared nanocapsules compared to the free drug. The nano-based hydrogels demonstrated non-Newtonian pseudoplastic behavior and an increased αBIS in vitro release profile without causing skin irritation in rabbits. Drug retention within the dermis and epidermis layers significantly surpassed that of drug-free hydrogel. Moreover, in vivo histopathological studies and myeloperoxidase (MPO) enzyme activity, revealed that hydrogel containing bisabolol nanocapsules exhibited The best anti-inflammatory effect. The results showed that hydrogels containing bisabolol nanocapsules markedly alleviated dermatitis-related inflammation and reduced skin thickness in Balb/c mice. Our findings support nanocapsules as an effective drug delivery system to enhance αBIS stability, bioavailability, and therapeutic efficacy in AD treatment.

Abstract
Apocynin (APO), a well-known bioactive plant-based phenolic phytochemical with renowned anti-inflammatory and antioxidant pharmacological activities, has recently emerged as a specific nicotinamide adenine dinucleotide phosphate-oxidase (NADPH) oxidase inhibitor. As far as we know, no information has been issued yet regarding its topical application as a nanostructured-based delivery system. Herein, APO-loaded Compritol® 888 ATO (lipid)/chitosan (polymer) hybrid nanoparticles (APO-loaded CPT/CS hybrid NPs) were successfully developed, characterized, and optimized, adopting a fully randomized design (32) with two independent active parameters (IAPs), namely, CPT amount (XA) and Pluronic® F-68 (PF-68) concentration (XB), at three levels. Further in vitro-ex vivo investigation of the optimized formulation was performed before its incorporation into a gel base matrix to prolong its residence time with consequent therapeutic efficacy enhancement. Subsequently, scrupulous ex vivo-in vivo evaluations of APO-hybrid NPs-based gel (containing the optimized formulation) to scout out its momentous activity as a topical nanostructured system for beneficial remedy of rheumatoid arthritis (RA) were performed. Imperatively, the results support an anticipated effectual therapeutic activity of the APO-hybrid NPs-based gel formulation against Complete Freund's Adjuvant-induced rheumatoid arthritis (CFA-induced RA) in rats. In conclusion, APO-hybrid NPs-based gel could be considered a promising topical nanostructured system to break new ground for phytopharmaceutical medical involvement in inflammatory-dependent ailments.

Abstract
The present study was conducted to formulate ethosomal thermoreversible in situ gel of apixaban, an anticoagulant drug, for nasal delivery. Ethosomes were formed, of lecithin, cholesterol, and ethanol, by using thin-film hydration method. The prepared ethosomes were characterized by Zetasizer, transmission electron microscope, entrapment efficiency, and in vitro study. The selected ethosomal formula (API-ETHO2) was incorporated in gel using P407 and P188 as thermoreversible agents and carbopol 934 as mucoadhesive agent. Box-Behnken design was used to study the effect of independent variables (concentration of P407, P188, and carbopol 934) on gelation temperature, mucoadhesive strength, and in vitro cumulative percent drug released at 12h (response variables). The optimized formulation was subjected to compatibility study, ex vivo permeation, histopathological examination for the nasal mucosa, and in vivo study. API-ETHO2 was spherical with an average size of 145.1±12.3 nm, zeta potential of -20±4 mV, entrapment efficiency of 67.11%±3.26, and in vitro % release of 79.54%±4.1. All gel formulations exhibited an acceptable pH and drug content. The optimum gel offered 32.3°C, 1226.3 dyne/cm2, and 53.50% for gelation temperature, mucoadhesive strength, and in vitro percent released, respectively. Apixaban ethosomal in situ gel evolved higher ex vivo permeation (1.499±0.11 μg/cm2h) through the nasal mucosa than pure apixaban gel. Histopathological study assured that there is no necrosis or tearing of the nasal mucosa happened by ethosomal gel. The pharmacokinetic parameters in rabbit plasma showed that intranasal administration of optimized API-ethosomal in situ gel achieved higher Cmax and AUC0-∞ than unprocessed API nasal gel, nasal suspension, and oral suspension. The ethosomal thermoreversible nasal gel established its potential to improve nasal permeation and prolong anticoagulant effect of apixaban.

Abstract
Methotrexate (MTX) is the first line of choice for the management of rheumatoid arthritis (RA) and has been reported for its low bioavailability and side effects. Combination therapy has been widely investigated to overcome bioavailability issues and to reduce adverse effects associated with monotherapy. Various phytoconstituents such as resveratrol (RSV) and curcumin have been found to possess potent anti-inflammatory activity via downregulating the signaling of cytokines (interleukin [IL]-1, IL-6, and tumor necrosis factor alpha) and nuclear factor kappa B signaling. The prime objective of this study was to develop transdermal gel containing MTX-RSV loaded nanoemulsions (NEs) to overcome bioavailability issues and adverse effects of RA monotherapy. The NEs optimized by using Box-Behnken Design were incorporated within gel, and an in vitro skin permeation study performed on rat skin by using vertical Franz diffusion cells exhibited controlled drug release up to 48 h. Subsequently, anti-inflammatory and potential anti-arthritic activities of the combination in nanocarrier were assessed in rats and showed 78.76 ± 4.16% inhibition in inflammation and better anti-arthritic effects. Consequently, integration of dual delivery with nanotechnology can hopefully produce successful therapeutic options for rheumatic diseases.

Abstract
Topical administration of drugs presents some advantages over other routes; the drug can be
administered in the anatomical region to be treated, limiting the systemic distribution and side effects.
However, the structure of the skin makes it a highly effective barrier to drug permeation. Amongst the
strategies to overcome this obstacle, liposomes are interesting vehicles for delivering the drugs into the
skin, the synovial cavity or other regions affected by inflammatory or degenerative conditions.
Liposomes are lipid carriers of nanometric size formed by phospholipid bilayers. They have the advantages
of preparation feasibility and biological compatibility associated with the possibility of carrying
either lipophylic and/or hydrophylic compounds, and have been extensively used in various drug delivery
systems, for drug targeting, controlled release and permeation enhancement of drugs. Conventional
liposomes are not very stable and not suitable for dermal administration after topical application, since
they accumulate on the skin surface due to the rigidity of the lipid layers and suffer dehydration, culminating
in their fragmentation. Other formulations have emerged in the meantime, such as transfersomes,
niosomes or ethosomes. The present work consists of a review on the published scientific papers regarding
the development of liposomal formulations containing non-steroidal anti-inflammatory drugs for the
purpose of relieving the symptomatology of inflammatory and degenerative ailments. The exposition
summarizes data relating to liposome type, composition, preparation method, liposome characterization,
topical vehicle used, in vitro permeation studies performed, in vivo anti-inflammatory assays carried out
and results obtained in the different studies published in the last five years.

Abstract
The main objective of this study was to develop and evaluate self-nanoemulsifying drug delivery system (SNEDDS) of curcumin (Cur) to enhance their solubility as well as improve skin permeation; and evaluate wound healing potential of Cur via SNEDDS in comparison with standards pure eucalyptus oil-SNEDDS (Euc-SNEDDS), pure curcumin suspension (Cur-S), and standard fusidic acid followed by their anti-inflammatory action. Curcumin-loaded different SNEDDS formulations were formulated through aqueous phase titration method and the zones of SNEDDS were recognized by the construction of phase diagrams. Eucalyptus oil, Tween 80 (surfactant), and Transcutol HP (co-surfactant) were selected on the basis of their solubility and highest nanoemulsion region. Characterization of thermodynamic stability for Cur-loaded SNEDDS was evaluated by its globule size, zeta potential, polydispersity index, viscosity, % transmittance, refractive index, and surface morphology. Cur-SNEDDS (Cur-SN4) was optimized and selected on the basis of their excellent physicochemical parameters for in vivo activity. The particle size (59.56 ± 0.94 nm), % transmittance (99.08 ± 0.07%), and PDI (0.207 ± 0.011 were observed for optimized Cur-SNEDDS. TEM and SEM showed their smooth and spherical shape of the morphological characterization with zeta potential (- 21.41 ± 0.89), refractive index (1.341 ± 0.06), and viscosity (11.64 ± 1.26 cp) for optimized Cur-SNEDDS. Finally, optimized Cur-SNEDDS was used to enhance skin permeation with improvement in the solubility of Cur. However, optimized Cur-SNEDDS showed significant wound healing activity as compared with pure eucalyptus oil and Cur-S on topical application. Optimized Cur-SNEDDS showed healing of wound as compared to standard fusidic acid. Optimized Cur-SNEDDS exhibited no signs of inflammatory cells on the histopathological studies of treated rats which were recommended the safety and non-toxicity of Cur-SNEDDS. Newly developed Cur-SNEDDS could be successfully used to enhance Cur-solubility and skin permeation, as well as suggested a potential role of Cur-SNEDDS for better improvement of wound healing activity followed by anti-inflammatory action of Cur via topical application.

Abstract
This review highlights in vitro drug dissolution/permeation methods available for topical and transdermal nanocarriers that have been designed to modulate the propensity of drug release, drug penetration into skin, and permeation into systemic circulation. Presently, a few of USFDA-approved in vitro dissolution/permeation methods are available for skin product testing with no specific application to nanocarriers. Researchers are largely utilizing the in-house dissolution/permeation testing methods of nanocarriers. These drug release and permeation methods are pending to be standardized. Their biorelevance with reference to in vivo plasma concentration-time profiles requires further exploration to enable translation of in vitro data for in vivo or clinical performance prediction.

Abstract
The aim of this study was to develop and evaluate a curcumin (Cur) nanoemulsion (NE) and enhance transdermal drug delivery. The comparative effects of Cur-NE were evaluated in terms of wound healing and anti-inflammatory action. Clove oil (oil), Tween-80 (surfactant), and PEG-400 (co-surfactant) were selected on the basis of their solubility and maximum nanoemulsion region. An aqueous micro-titration method with high-energy ultrasonication was used for the preparation of Cur-NE. This method was optimized to find the best NE, followed by a five-factor, three-level, central composite design. % oil, % Smix, ultrasonication time (min), ultrasonication intensity (%), and temperature (°C) were selected and optimized as independent variables. The optimized NE had parameters of 5.0% oil, 10% Smix, ultrasonication time (10 min), 40% ultrasonication intensity and 50 °C temperature, which were applied as independent and dependent variables. On the basis of experimental data of the dependent variables, we calculated a hydrodynamic diameter of 93.64 ± 6.48 nm, transmittance of 98.64 ± 0.37%, and PDI of 0.263 ± 0.021. TEM and SEM results revealed the smooth and spherical shape of the particles in the NE, with a zeta potential of −11.67 ± 0.11, refractive index of 1.71 ± 0.034, viscosity of 37 ± 7 cp, pH of 7.4 ± 0.07, and drug content of 98.11 ± 0.16% for the optimized Cur-NE. Cur-NE optimization with clove oil, Tween-80, and PEG-400 might be useful for enhancing the skin permeation of Cur. In conclusion, Cur-NE played a significant role in wound healing and exhibited anti-inflammatory effects, demonstrating its potential as a nanoformulation for safe and nontoxic transdermal delivery. The aim of this study was to develop and evaluate a curcumin (Cur) nanoemulsion (NE) and enhance transdermal drug delivery.![]()

Abstract
The current study was conducted to develop vesicular ethosomal gel (ethogel) systems for upgrading the transdermal delivery of anti-hypertensive carvedilol. Ethosomes composed of Phospholipon 100 H, cholesterol, ethanol, and Transcutol P at different ratios, were prepared by thin-film hydration method with sonication. Carvedilol-loaded ethosomes were characterized by microscopic examinations followed by other in-vitro assessments. Selected ethosomal formulation (E10) was incorporated into different concentrations of gelling agents to prepare the ethogel formulations. Ethogels were subjected to physicochemical characterization, compatibility, and in-vitro drug release studies. Ex-vivo skin permeation and retention studies were performed followed by in-vivo studies in induced hypertensive rats. The smooth ethosomes demonstrated vesicular size of 201.55-398.55 nm, entrapment efficiency of 30.00-90.66% and loading capacity of 7.64-43.04% with zeta potential range of -30.30 to -44.90 mV. The homogeneous ethogels exhibited appropriate results of pH and drug content measurements. Spreadability was observed as a function of viscosity as the latter increased, the former decreased. The ethogel formulation (G2) manifested satisfactory physical appearance, spreadability, viscosity, and in-vitro release. In comparison to pure carvedilol gel, tested formulations (E10 and G2) developed high ex-vivo permeation, steady-state flux and drug retention through skin layers. The in-vivo study of G2 formulation revealed a significant gradual decline (p < 0.01) in the mean arterial pressure of rats at the second hour of experiment (146.11 mmHg) with continuous significant decrease (p < 0.001) after 6 h (98.88 mmHg). In conclusion, ethogels as promising lipid carriers proved their potential to enhance skin permeation with extended anti-hypertensive action of carvedilol.
