Abstract
Transethosomes, classified as 3rd generation nanocarriers, have gained global acclaim due to their profound potential in addressing diverse medical conditions. Their superior dermal penetration, attributed to essential constituents, such as edge activators and alcohol, sets them apart from other nanoformulations. The current review article embarks with an introduction followed by a comprehensive exploration of transethosome structures, differentiating them from fellow nanocarriers. A detailed analysis of characteristics and the spectrum of marketed products of various nanocarriers is also provided. Furthermore, the article offers a taxonomy of preparation methods of transethosomes and reports the frequently employed methods. It briefly surveys research studies encompassing various drug categories, spanning a wide range of medical conditions. In summary, this review article is dedicated to achieving several pivotal aims and objectives. We aim to substantiate the superior attributes of transethosomes when compared to conventional commercial products and other nanoformulations, demonstrating their clinical promise in addressing various human medical conditions. Additionally, we seek to elucidate the regulatory pathway required to secure approvals for transethosomes from relevant regulatory authorities and shine a light on their innovative potential as revealed in patent literature. Collectively, these objectives contribute to a comprehensive understanding of the significance and potential of transethosomes in the field of pharmaceutical nanotechnology.

Abstract
Herein we designed, optimized, and characterized the Metformin Hydrochloride Transethosomes (MTF-TES) and incorporate them into Chitosan gel to develop Metformin Hydrochloride loaded Transethosomal gel (MTF-TES gel) that provides a sustained release, improved transdermal flux and improved antidiabetic response of MTF. Design Expert® software (Ver. 12, Stat-Ease, USA) was applied for the statistical optimization of MTF-TES. The formulation with Mean Particle Size Distribution (MPSD) of 165.4 ± 2.3 nm, Zeta Potential (ZP) of -21.2 ± 1.9 mV, Polydispersity Index (PDI) of 0.169 ± 0.033, and MTF percent Entrapment Efficiency (%EE) of 89.76 ± 4.12 was considered to be optimized. To check the chemical incompatibility among the MTF and other formulation components, Fourier Transform Infrared (FTIR) spectroscopy was performed and demonstrated with no chemical interaction. Surface morphology, uniformity, and segregation were evaluated through Transmission Electron Microscopy (TEM). It was revealed that the nanoparticles were spherical and round in form with intact borders. The fabricated MTF-TES has shown sustained release followed by a more pronounced effect in MTF-TES gel as compared to the plain MTF solution (MTFS) at a pH of 7.4. The MTF-TES has shown enhanced permeation followed by MTF-TES gel as compared to the MTFS at a pH of 7.4. In vivo antidiabetic assay was performed and results have shown improved antidiabetic potential of the MTF-TES gel, in contrast to MTF-gel. Conclusively, MTF-TES is a promising anti-diabetic candidate for transdermal drug delivery that can provide sustained MTF release and enhanced antidiabetic effect.

Abstract
This study aimed to fabricate Miconazole Nitrate transethosomes (MCZN TESs) embedded in chitosan-based gel for the topical treatment of Cutaneous Candidiasis. A thin film hydration method was employed to formulate MCZN TESs. The prepared MCZN TESs were optimized and analyzed for their physicochemical properties including particle size (PS), polydispersity index (PDI), zeta potential (ZP), entrapment efficiency (%EE), Fourier transform infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC), deformability, and Transmission electron microscopy (TEM). In vitro release, skin permeation and deposition, skin irritation, antifungal assay, and in vivo efficacy against infected rats were evaluated. The optimized MCZN TESs showed PS of 224.8 ± 5.1 nm, ZP 21.1 ± 1.10 mV, PDI 0.207 ± 0.009, and % EE 94.12 ± 0.101 % with sustained drug release profile. Moreover, MCZN TESs Gel exhibited desirable pH, spreadability, and viscosity. Notably, the penetration and deposition capabilities of MCZN TESs Gel showed a 4-fold enhancement compared to MCZN TESs. Importantly, in vitro antifungal assay elaborated MCZN TESs Gel anti-fungal activity was 2.38-fold more compared to MCZN Gel. In vivo, studies showed a 1.5 times reduction in the duration of treatment MCZN TESs Gel treated animal group. Therefore, studies demonstrated that MCZN TESs could be a suitable drug delivery system with higher penetration and good antifungal potential.

Abstract
Vitiligo is a common autoimmune skin disorder that is characterized by patchy depigmentation of the skin due to melanocytes and melanin loss. Herein, photodynamic therapy mediated 8-methoxypsoralen (8-MOP), has been used fortified with topical oleyl alcohol-based transethosomes; to overcome the poor solubility and adverse effects associated with 8-MOP oral delivery. A 23 factorial design was used to study the formulation variables. In vitro and ex-vivo characterization besides a clinical study were conducted to assess therapeutic efficacy of the formulation. Results revealed that transethosomes were superior to transfersomes regarding drug protection from degradation. The optimized transethosomal formulation, composed of 50 mg oleyl alcohol, 10 mg Tween 80® and 20% v/v ethanol, exhibited high entrapment efficiency (83.87 ± 4.1%) and drug loading (105.0 ± 0.2%). Moreover, it showed small vesicular size (265.0 ± 2.9 nm) and PDI (0.19). The formulation depicted core and shell structure, high deformability index (12.45 ± 0.7 mL/s) and high ex-vivo skin permeation. The topical application of the developed 8-MOP transethosomal gel enhanced the effect of NB UVB radiation in the treatment of vitiligo patients and exhibited no side effects. Hence, it can be used as a future strategy for delivering 8-MOP without the need of systemic application.

Abstract
The skin embodies a relatively large and readily accessible surface area to absorb a drug through a non-invasive procedure. The vesicular carrier systems such as liposomes, ethosomes, and transethosomes have been explored as non-invasive systems for transdermal delivery of drugs. In the present study, different vesicular carriers were prepared by the thin-film hydration method with modification, and various parameters like size, elasticity, and release profiles were evaluated. Ethosomes and transethosomes have shown the smaller size of 362.21 ± 55.76 and 314.34 ± 41.21 nm, with deformity of 19.34% and 25.04%, respectively, compared with liposomes. The FTIR study of the skin before and after the application of vesicular formulation was performed. The ethosomes and transethosomes changed the orthorhombic phase to the liquid crystalline phase to move the vesicular carrier with the drug to cross the stratum corneum (SC) of the skin. The thermotropic behaviour of drug and vesicular carrier ingredients was studied using differential scanning calorimetry (DSC). Fluorescence images of vesicular-skin permeation have revealed that ethosome and transethosome formulation have shown deeper penetration across the SC and epidermis. The in vitro drug release from the ethosomes and transethosomes has shown 93.34 ± 1.23% and 95.45 ± 2.67% of drug release using Franz diffusion cell and porcine skin as a membrane. The nanostructured flexible vesicular carrier containing ethanol alone and a combination of ethanol and edge activator is a perfect carrier for drug penetration to the deeper skin layer and maintaining the sustained release of drug for a prolonged time.

Abstract
OBJECTIVE The present study aims to formulate and evaluate a novel vesicular formulation of resveratrol to achieve its dermatological benefits in terms of antiphotoaging and antioxidant. METHOD In this study, resveratrol-loaded deformable vesicular gel was prepared and optimized using Box-Behnken design. Selected critical material attributes were amount of phospholipid (X1), concentration of ethanol (X2), and amount of sodium cholate (X3). The prepared transethosomal vesicles were incorporated into carbopol gel base and evaluated. Ultraviolet radiation-induced skin aging and oxidative stress model in Swiss Albino mice was used to evaluate the clinical potential of the developed formulation and compared with conventional gel. Levels of Super Oxide Dismutase (SOD), catalase, glutathione peroxidase, protein content, and malondialdehyde were measured to assess the extent of lipid peroxidation and reactive oxygen species inhibition in different groups. RESULT DoE was successfully employed to optimize the vesicular formulation. Vesicle size was found to be 158.9 ± 7.65 nm, while values of entrapment efficiency and skin deposition were found to be 77.83 ± 2.87% and 371.84 ± 5.12 µg cm-2, respectively. Visual skin grading and histopathological studies confirmed the higher efficacy of transethosomal resveratrol against oxidative stress. Significant enhancement in the levels of antioxidant enzymes and protein content confirmed the ameliorated potential of flexible transethosomal resveratrol as compared to the plain gel of resveratrol. CONCLUSION Restoration of first-line defense mechanism in chronic UV-exposed animal model has proved that transethosomal resveratrol can be developed as an innovative cosmetic product for significant improvement and repair of photo-aged skin.

Abstract
Skin carcinogenesis is a common malignancy affecting humans worldwide, which could benefit from nutraceuticals as a solution to the drawbacks of conventional skin cancer treatment. (-)-epigallocatechin-3-gallate (EGCG) is a promising nutraceutical in this regard; however, it suffers chemical instability and low bioavailability resulting in inefficient delivery. Therefore, EGCG encapsulation in ultradeformable colloidal vesicular systems, namely: penetration enhancer-containing vesicles (PEVs), ethosomes and transethosomes (TEs) for topical administration has been attempted in this study to overcome the problems associated with the use of free EGCG. The prepared vesicles were characterized for their entrapment efficiency, TEM visualization, chemical compatibility, antioxidant properties, ex-vivo skin deposition, photodegradation and physical stability after storage. Most of the prepared vesicles exhibited reasonable skin deposition and preservation of the inherent antioxidant properties of EGCG with good physical stability. EGCG-loaded PEVs and TEs exhibited an inhibitory effect on epidermoid carcinoma cell line (A431) in addition to reduced tumor sizes in mice, confirmed with histopathological analysis and biochemical quantification of skin oxidative stress biomarkers; glutathione, superoxide dismutase and catalase, as well as lipid peroxidation. EGCG PEVs succeeded in offering an effective delivery system targeting skin cancer, which is worthy of further experimentation.

Abstract
This study aimed to formulate suitable nanovesicles (NVs) for transdermal delivery of Ondansetron. It also illustrated a practical example for the importance of Box-Cox transformation. A 23 full factorial design was used to enable testing transfersomes, ethosomes, and transethosomes of Ondansetron simultaneously. The independent variables (IVs) studied were sodium taurocholate amount, ethanol volume in hydration medium and sonication time. The studied dependent variables (DVs) were: particle size (PS), zeta potential (ZP) and entrapment efficiency (EE). Polynomial equations were used to study the influence of IVs on each DV. Numerical multiple response optimization was applied to select an optimized formula (OF) with the goals of minimizing PS and maximizing ZP absolute value and EE. Box-Cox transformation was adopted to enable modeling PS raised to the power of 1.2 with an excellent prediction R2 of 1.000. ZP and EE were adequately represented directly with prediction R2 of 0.9549 and 0.9892 respectively. Response surface plots helped in explaining the influence of IVs on each DV. Two-sided 95% prediction interval test and percent deviation of actual values from predicted ones proved the validity of the elucidated models. The OF was a transfersomal formula with desirability of 0.866 and showed promising results in ex-vivo permeation study.

Abstract
Paeonol shows effective anti-allergic, anti-inflammatory and analgesic activities. However, because of its poor solubility in water and high volatility at room temperature, the application of this drug is restricted in the clinic. The objective of this research was to develop a biocompatible paeonol formulation with improved stability, skin delivery and pharmacokinetic efficiency. In this paper, paeonol-loaded vesicles were prepared using an ethanol injection method. Nano-vesicles were characterized for their physical properties and encapsulation efficiency (EE). Drug permeation behavior in vitro and deposition quantity in porcine ear skin were measured with a Valia-Chien (V-C) diffusion device. Additionally, a validated and sensitive high performance liquid chromatography (HPLC) method was developed to analyze paeonol concentrations in rat plasma after transdermal administration. The results showed that the particle-size order of the nano-vesicles was the following: transethosomes (122.5±7.5nm)<transfersomes (256.5±8.9nm). Compared to the paeonol transfersomes, the transethosomes had a higher EE (85.5±5.2%), and they showed a spherical morphology with a smooth surface when viewed under a transmission electron microscope (TEM). In an in vitro permeation study, the paeonol transethosomes showed an enhanced transdermal flux of 95.7±8.8μg/cm2/h and a higher deposition quantity in porcine ear skin compared to the transfersomes. A one-compartment first-order absorption model could be used to describe the pharmacokinetics of paeonol in rats after transdermal administration. The AUC of the paeonol transethosomes was approximately 1.57- and 3.52-fold higher than those of the transfersomes and a saturated solution of paeonol in 35% ethanol, respectively. The results demonstrated that the paeonol transethosomes had a narrow size distribution, high encapsulation efficiency, and long residence in the plasma. This formulation remarkably enhanced the bioavailability of paeonol.
