RSC Adv 2024; 14:26524-26543. [PMID: 39175684 PMCID: PMC11339782 DOI: 10.1039/d4ra03542a] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2024] [Accepted: 07/18/2024] [Indexed: 08/24/2024] Open
Abstract
Presently, the development of functional derivatives exploiting biocompatible pharmaceutical materials has become a pressing demand. Among them, ascorbyl-2-glucoside (AA-2G), an ascorbic acid derivative, has significant potential owing to its stability, solubilization and antioxidant prospects. Herein, AA-2G was utilized for the fabrication of itraconazole (ITZ) spanlastics, which were denoted as "glucospanlastics". Subsequently, the newly designed glucospanlastics were characterized to determine their dimensions, charge, entrapment, solubilization efficiency, morphology, stability and antioxidant activity. Further, their cytotoxicity towards A431 cells and their ex vivo skin deposition were investigated. Subsequently, the competence of the formulated cream containing glucospanlastics to suppress Ehrlich carcinoma and modulate the antioxidant profile was evaluated in vivo. The results revealed that the proposed nano-sized glucospanlastics performed better than conventional spanlastics (without AA-2G) with respect to optimal solubilization efficiency and ITZ entrapment (>95%) together with antioxidant, cytotoxic and skin permeation potentials. More importantly, glucospanlastics containing 10 and 20 mg AA-2G demonstrated considerable tumor suppression and necrosis, improvement in glutathione (GSH) content by 1.68- and 2.26-fold, elevation of total antioxidant capacity (TAC) levels by 1.67- and 2.84-fold and 1.78- and 2.03-fold reduction in malondialdehyde (MDA) levels, respectively, compared to a conventional ITZ cream. These innovative antioxidant vesicles show future potential for the dermal delivery of cancer-directed therapies.

Abstract
Over the last few decades, cancer has been considered a clinical challenge, being among the leading causes of mortality all over the world. Although many treatment approaches have been developed for cancer, chemotherapy is still the most utilized in the clinical setting. However, the available chemotherapeutics-based treatments have several caveats including their lack of specificity, adverse effects as well as cancer relapse and metastasis which mainly explains the low survival rate of patients. Lipid nanoparticles (LNPs) have been utilized as promising nanocarrier systems for chemotherapeutics to overcome the challenges of the currently applied therapeutic strategies for cancer treatment. Loading chemotherapeutic agent(s) into LNPs improves drug delivery at different aspects including specific targeting of tumours, and enhancing the bioavailability of drugs at the tumour site through selective release of their payload, thus reducing their undesired side effects on healthy cells. This review article delineates an overview of the clinical challenges in many cancer treatments as well as depicts the role of LNPs in achieving optimal therapeutic outcomes. Moreover, the review contains a comprehensive description of the many LNPs categories used as nanocarriers in cancer treatment to date, as well as the potential of LNPs for future applications in other areas of medicine and research.

Abstract
Vitamin D is one significant prohormone substance in human organ systems. It is a steroidal hormone produced in the skin upon exposure to UVB rays. This paper presents a systematic review of the utilization of topical vitamin D, specifically cholecalciferol, calcipotriol, and tacalcitol, in the treatment of vitiligo. It considers the role of vitamin D in stimulating the synthesis of melanin and melanogenesis, which can help with the process of repigmentation. The inclusion of calcipotriol or tacalcitol in Narrowband Ultraviolet Phototherapy (NB-UVB) has shown the potential to enhance therapeutic outcomes for vitiligo. However, their effectiveness in combination with Psoralens Long Wave Ultraviolet Radiation (PUVA) and Monochromatic Excimer Light (MEL) treatment for vitiligo is limited. In contrast, combining topical corticosteroids with vitamin D analogues has demonstrated superior efficacy in treating vitiligo compared to using vitamin D analogues alone, while also providing the added benefit of reducing corticosteroid-related adverse effects. In addition, treating stable vitiligo with topical cholecalciferol and microneedling has shown success. Future studies are needed to ascertain an efficient method of administering vitamin D topically as an anti-vitiligo agent.

Abstract
The abundant synthesis and accretion of melanin inside skin can be caused by activation of melanogenic enzymes or increase in number of melanocytes. Melasma is defined as hyperpigmented bright or dark brown spots which are symmetrically distributed and have serrated and irregular borders. The three general categories of pigmentation pattern include centro facial pattern, malar pattern, and mandibular pattern. Exposure to UV rays, heat, use of cosmetics and photosensitizing drugs, female sex hormonal therapies, aberrant production of melanocyte stimulating hormone, and increasing aesthetic demands are factors which cause the development of melasma disease. This review gives a brief overview regarding the Fitzpatrick skin phototype classification system, life cycle of melanin, mechanism of action of anti-hyperpigmenting drugs, and existing pharmacotherapy strategies for the treatment of melasma. The objectives of this review are focused on role of cutting-edge nanotechnology-based strategies, such as lipid-based nanocarriers, i.e., lipid nanoparticles, microemulsions, nanoemulsions, liposomes, ethosomes, niosomes, transfersomes, aspasomes, invasomes penetration-enhancing vesicles; inorganic nanocarriers, i.e., gold nanoparticles and fullerenes; and polymer-based nanocarriers i.e., polymeric nanoparticles, polymerosomes, and polymeric micelles for the management of hyperpigmentation.

Response surface methodological approach for optimization of photodynamic therapy of onychomycosis using chlorin e6 loaded nail penetration enhancer vesicles. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY. B, BIOLOGY 2022; 232:112461. [PMID: 35551052 DOI: 10.1016/j.jphotobiol.2022.112461] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2021] [Revised: 11/07/2021] [Accepted: 05/02/2022] [Indexed: 06/15/2023]
Abstract
Antimicrobial photodynamic inactivation (aPDI) has a tremendous potential as an alternative therapeutic modality to conventional antifungals in treatment of onychomycosis, yet the nail barrier properties and the deep-seated nature of fungi within the nails remain challenging. Therefore, the aim of this study was to prepare, optimize, and characterize Chorin e6 (Ce6) nail penetration enhancer containing vesicles (Ce6-nPEVs) and evaluate their photodynamic mediated effect against Trichophyton rubrum (T.rubrum); the main causative agent of onychomycosis. Optimization of the particle size and encapsulation efficiency of nPEVs was performed using a four-factor two-level full factorial design. The transungual delivery potential of the selected formulation was assessed in comparison with the free drug. The photodynamic treatment conditions for T.rubrum aPDI by free Ce6 was optimized using response surface methodology based on Box-Behnken design, and the aPDI effect of the selected Ce6-nPEVs was evaluated versus the free Ce6 at the optimized condition. Results showed that formulations exhibited high encapsulation efficiency for Ce6 ranging from 79.4 to 98%, particle sizes ranging from 225 to 859 nm, positive zeta potential values ranging from +30 to +70 mV, and viscosity ranging from 1.26 to 3.43 cP. The predominant parameters for maximizing the encapsulation efficiency and minimizing the particle size of Ce6-nPEVs were identified. The selected formulation showed 1.8-folds higher nail hydration and 2.3 folds improvement in percentage of Ce6 up-taken by nails compared to the free drug. Results of the microbiological study confirmed the reliability and adequacy of the Box-Behnken model, and delineated Ce6 concentration and incubation time as the significant model terms. Free Ce6 and Ce6-nPEVs showed an equipotent in vitro fungicidal effect on T.rubrum at the optimized conditions, however Ce6-nPEVs is expected to show a differential effect at the in vivo level where the advantage of the enhanced nail penetration feature will be demonstrated.

Abstract
BACKGROUND Macitentan blocks endothelin receptors in order to control the pulmonary arterial hypertension (PAH). Oral administration of macitentan is associated with painful urination and troubled breathing. OBJECTIVES Formulated macitentan hydrogel film was used for examining the control of intraocular pressure, and the effect of surfactant and cosurfactant was studied. METHODS Macitentan ocular film formulation has been prepared in hydroxypropyl methylcellulose (HPMC) matrix system using different surfactant/co-surfactant system, and intraocular pressure was monitored on normotensive rabbit eyes after application in the cul-de-sac. RESULTS The solid state characterization of the film indicated amorphisation of macitentan and no issues regarding major incompatibility was observed. Combination of surfactant, co-surfactant and hydrophilic co-solvent systems in the said films markedly improved the drug release and mucosal tissue permeation. Presence of PEG and Transcutol significantly improved ex vivo corneal permeation of MP and MT respectively compared to other films. Transcutol (MT) exhibited greatest difference among the formulations by improving the vesicular bilayer fluidity and reducing the mucosal tissue barrier facilitating the transcorneal diffusion. A combination of diffusion and erosion control behavior was observed in drug release and corneal permeation of the films due to the balanced liquid penetration and polymeric chain relaxation rate. MP and MT films were used for further in vivo studies to achieve possible effective and prolonged control of intraocular pressure. In vivo study has revealed the reduction in intraocular pressure upto about 23 % when tested on normotensive rabbit model. The films has managed to lower the IOP upto 3 h. CONCLUSION Developed macitentan hydrogel film containing Transcutol (MT) could have a high potential for the control and management of ocular hypertension after topical application.

Abstract
Transdermal administration has gained much attention due to the remarkable advantages such as patient compliance, drug escape from first-pass elimination, favorable pharmacokinetic profile and prolonged release properties. However, the major limitation of these systems is the limited skin penetration of the stratum corneum, the skin's most important barrier, which protects the body from the insertion of substances from the environment. Transdermal drug delivery systems are aiming to the disruption of the stratum corneum in order for the active pharmaceutical ingredients to enter successfully the circulation. Therefore, nanoparticles are holding a great promise because they can act as effective penetration enhancers due to their small size and other physicochemical properties that will be analyzed thoroughly in this report. Apart from the investigation of the physicochemical parameters, a comparison between the different types of nanoparticles will be performed. The complexity of skin anatomy and the unclear mechanisms of penetration should be taken into consideration to reach some realistic conclusions regarding the way that the described parameters affect the skin permeability. To the best of the authors knowledge, this is among the few reports on the literature describing the technology of transdermal delivery systems and how this technology affects the biological activity.

Abstract
Dermatological products constitute a big segment of the pharmaceutical market. From conventional products to more advanced ones, a wide variety of dosage forms have been developed till current date. A representative of the advanced delivery means is carrier-based systems, which can load large number of drugs for treatment of dermatological diseases, or simply for cosmeceutical purposes. To make them more favorable for topical delivery, further incorporation of these carriers in a topical vehicle, such as gels or creams is made. Therefore in this review article, an overview is compiled of the most commonly encountered novel carrier based topical delivery systems; namely lipid based (nanoemulsions, microemulsions, solid lipid nanoparticles [SLNs] and nanostructured lipid carriers [NLCs]), and vesicular carriers (non-deformable, such as liposomes, niosomes, emulsomes and cerosomes, and deformable, such as transfersomes, ethosomes, transethosomes, and penetration enhancer vesicles), with special emphasis on those loaded in a secondary gel vehicle. A special focus was made on the commonly encountered dermatological diseases, such as bacterial and fungal infections, psoriasis, dermatitis, eczema, vitiligo, oxidative damage, aging, alopecia, and skin cancer.

Abstract
Lipid nanoparticles (LNPs) have been proposed as carriers for drug skin delivery and targeting. As LNPs effectiveness could be increased by the addition of chemical penetration enhancers (PE), in this work, the feasibility of incorporating PE into LNPs to improve idebenone (IDE) targeting to the skin was investigated. LNPs loading IDE 0.7% w/w were prepared using hydrophilic (propylene glycol, PG, 10% w/w or N-methylpyrrolidone, NMP, 10% w/w) and/or lipophilic PE (oleic acid, OA, 1% w/w; isopropyl myristate, IPM, 3.5% w/w; a mixture of 0.5% w/w OA and 2.5% w/w IPM). All LNPs showed small sizes (<60 nm), low polydispersity index and good stability. According to the obtained results, IDE release from LNPs was not the rate-limiting step in IDE skin penetration. No IDE permeation was observed through excised pigskin from all LNPs, while the greatest increase of IDE penetration into the different skin layers was obtained using the mixture OA/IPM. The antioxidant activity of IDE-loaded LNPs, determined by the oxygen radical absorbance capacity assay, was greater than that of free IDE. These results suggest that the use of suitable PE as LNPs components could be regarded as a promising strategy to improve drug targeting to the skin.

Abstract
Onychomycosis is considered a stubborn nail fungal infection that does not respond to conventional topical antifungal treatments. This study aimed to develop and characterize novel solid lipid nanoparticles (SLNs) formulae containing terbinafine HCl (TFH) and loaded with different nail penetration enhancers (nPEs). Three (nPEs) N-acetyl-L-cysteine, thioglycolic acid, and thiourea were used. Characterization of the prepared formulae was done regarding particle size, zeta potential, polydispersity index (PDI), entrapment efficiency (EE%), physical stability, in vitro release study, infrared (FT-IR), and their morphological structures. The selected formulae and the marketed cream Lamifen® were compared in terms of their antifungal activity against Trichophyton rubrum as well as their nail hydration and their drug uptake by the nail clippers. Thiourea was the nPE of choice; formulae (N2 and N8), with thiourea, were considered the optimum TFH SLNs containing nPEs. They were selected for their optimum particle size of 426.3 ± 10.18 and 450.8 ± 11.45 nm as well as their highest EE% of 89.76 ± 1.25 and 90.35 ± 1.33, respectively. The in vitro microbiological screening of the antifungal activity of these two formulae showed significantly larger zones of inhibition in comparison with the marketed product. The ex vivo screening of the drug uptake of the two selected formulae was significantly higher than that of the marketed product. The nPE formulae present a very promising option as they showed optimum physicochemical characterization with high antifungal activity and high drug uptake as well as good nail hydration effect.

Abstract
Treatment of skin ailments through systemic administration is limited due to toxicity and
patients discomfort. Hence, lower risk of systemic side effects from topical dosage forms like ointments,
creams, emulsions and gels is more preferred for the treatment of skin disease. Application
of lipid based carriers in drug delivery in topical formulations has recently become one of the major
approaches to improve drug permeation, safety, and effectiveness. These delivery systems include
liposomes, ethosomes, transfersomes, Nanoemulsions (NEs), Solid Lipid Nanoparticles (SLNs)
Nanostructured Lipid Carriers (NLCs) and micelles. Most of the liposomes and SLNs based products
are in the market while some are under investigation. Transcutaneous delivery of therapeutics
to the skin layer by novel lipid based carriers has enhanced topical therapy for the treatment of skin
ailments. This article covers an overview of the lipid-based carriers for topical uses to alleviate skin
diseases.

Abstract
Various lipid nanovesicular systems have been developed with the aim to enhance the delivery of drugs via transdermal route. However, their clinical applications are often limited due to the barrier nature of skin and lack of flexibility. Herein, we have modified the conventional nanoliposomes (CLs) prepared by a thin-film hydration method by the addition of a polyol (glycerol) to form novel lipid nanovesicular structures termed 'POLYOLIPOSOMES' (PLs). They were further named as PL-B (before film formation) and PL-A (after film formation), depending on the stage of glycerol addition during production. Optimized CLs, PL-B and PL-A showed spherical nanovesicles and hydrodynamic diameter of 181.3 ± 4.11 nm, 114.2 ± 7.21 nm and 170.2 ± 6.51 nm, respectively. PLs showed significantly higher % entrapment efficiency and deformability index in comparison to CLs, indicating their higher flexibility. Furthermore, DSC and attenuated total relection (ATR)-Fourier transform infrared (FTIR) studies revealed the intercalation of glycerol into the lipid bilayer of PLs and interaction between nanovesicles and skin. Moreover, ex vivo and in vivo skin permeation studies confirmed the enhanced drug delivery of PLs via the transdermal route. Taken together, these results illustrate the potential of PLs as a novel lipid nanovesicular system for drug delivery via the transdermal route for both systematic (PL-B) as well as cutaneous diseases (PL-A).

Abstract
Topical and transdermal application of active pharmaceutical ingredients to the skin is an attractive strategy being explored by formulation scientists to treat disease conditions rather than the oral drug delivery. Several approaches have been attempted, and many of them have emerged with significant clinical potential. However, the delivery of drugs across the skin is an arduous task due to permeation limiting barriers. It, therefore, requires the aid of external agents or carrier systems for efficient permeation. Lipid-based vesicular systems are carriers for the transport of drugs through the stratum corneum (dermal drug delivery) and into the bloodstream for systemic action (transdermal drug delivery) overcoming the barrier properties. This review article describes the various vesicular systems reported for skin delivery of actives with relevant case studies. The vesicular systems presented here are in the order of their advent from conventional systems to the advanced lipid vesicles. The design and development of drugs in vesicular systems have brought a new dimension to the treatment of disease conditions overcoming the permeation limiting barriers, thus improving its efficacy.

Abstract
Fenoldopam, a highly selective dopamine receptor agonist, is available in clinics as Corlopam™ i.v. for the management of severe hypertension. Recent reports demonstrate its anti-proliferative activity in vitro in a dose dependent manner. However, stability issues of the drug due to its susceptibility to oxidation, pH sensitivity, poor transdermal flux, and the barrier properties of skin present challenges to develop a topical formulation of fenoldopam. The aim of the present study is to suggest a stable topical formulation of fenoldopam for the treatment of psoriasis. Water washable ointment and glycerin-based carbopol anhydrous gel of fenoldopam intended for topical delivery were prepared and evaluated in vitro and in vivo. Results from pH dependent stability studies suggest the necessity to maintain acidic pH in final formulations. The presence of an acidic adjuster in ointment and unneutralised carbopol dispersion of anhydrous gel maintain the desired acidic environment in the formulations. Stability studies of prepared formulations performed for 90 days indicate that the drug remains stable in formulations. In vivo studies demonstrate the applicability of the formulations for better skin penetration, skin compliance, and photosafety. Efficacy studies using an imiquimod induced psoriasis model confirm the promising application of developed fenoldopam topical formulations for psoriasis.

Abstract
Introduction: Glaucoma affects more than 70 million people worldwide. One of the major therapeutic options for its management is based on the inhibition of the metalloenzyme carbonic anhydrases (CAs, EC 4.2.1.1). CA inhibitors (CAIs) diminish ocular hypertension in glaucomatous patients by reducing the rate of bicarbonate formation and thus, the secretion of the aqueous humor. Areas covered: This review is intended to cover the major contributions in terms of patent literature reports for the treatment of ophthalmic diseases by means of CAIs in a time frame spanning from 2013 to date. Expert opinion: The patent literature is dominated by innovative pharmaceutical formulations including a CAI alone or in combination with other therapeutic agents. Very few novelties within drug discovery are currently present and they mainly account for new CAI moieties and classical CAIs merged into scaffolds bearing additional chemical functionalities beneficial for the pharmacological treatment of the disease. It is reasonable to expect that in the near future the so-called 'old drugs' will achieve pharmacological performances in the management of ocular hypertension beyond any expectations and thus open a new era of drug repurposing merely based on material science advancements.

Abstract
Tazarotene (TAZ) is a topical synthetic retinoid used in psoriasis treatment, however, it is extremely lipophilic and exhibits skin irritation. Research is in a state of continuous advancement in the field of nanocarriers fabrication, and in this regard, we investigated the formulation of novel topically oriented nanovesicles; representing a combination of spanlastics and penetration enhancer vesicles, to be termed (fluidized-SNs). TAZ-loaded fluidized SNs were physicochemically characterized, tested for ex vivo cutaneous retention, and the selected formulation was compared with the marketed product Acnitaz® regarding clinical antipsoriatic activity. The selected fluidized-SNs enriched with 1% cineole exhibited high entrapment for TAZ (76.19%), suitable size and zeta potential of 241.5 ± 5.68 nm and -36.10 ± 2.50 mV respectively, and retaining of stability after refrigeration storage for one month. As hypothesized, cineole enriched fluidized-SNs exhibited remarkable TAZ deposition amounting to a total of 81.51% in the different skin layers. Upon clinical assessment, the presented formulation displayed superior traits compared to the marketed product, in terms of dermoscopic imaging, morphometric analysis of psoriatic lesions, and statistical analysis of PASI scores. Results confirmed that the prepared novel fluidized spanlastics formulation holds great promise for the treatment of psoriasis, and its benefit should futuristically be investigated in other topical diseases.

Abstract
Purpose: The current study aimed to compare 2 topical diclofenac products (diclofenac diethylamine [DEA] 1.16% emulsion and diclofenac sodium [Na] 5% gel). The quantitative evaluation of skin permeability and the qualitative evaluation of their physical characteristics were performed. Methods: The skin permeability of diclofenac DEA 1.16% emulsion and diclofenac Na 5% gel was compared in vitro using Franz diffusion cells following a single, fixed, 10 mg/cm2 dose of product applied to a 0.64 cm2 area of the stratum corneum surface of ex vivo human skin samples. The physical characteristics of the 2 formulations were assessed by rheological measurement and microscopy observation. Results: Diclofenac DEA 1.16% emulsion exhibited a statistically significant higher permeation through human skin at 24 hrs than diclofenac Na 5% gel (554 vs 361 ng/cm2, respectively; ratio of adjusted geometric means, 1.54 [95% CI, 1.14-2.07]). When expressed as a percentage of the applied dose of diclofenac that permeated through human skin, a 7-fold difference was observed between the diclofenac DEA 1.16% emulsion (0.54%) and the diclofenac Na 5% gel (0.077%). Qualitative composition and physical characterization showed differences between the formulations that may explain some of the permeation data observed. Based on rheological assessments, diclofenac Na 5% gel had a higher viscosity (24.82 Pa.s) than diclofenac DEA 1.16% emulsion (10.29 Pa.s). Conclusion: A topical diclofenac product with a higher concentration of the active ingredient does not necessarily lead to greater absorption relative to a product with lower concentration of the active ingredient but different characteristics. These observations highlight the importance of considering parameters beyond drug concentration, such as composition, which may influence the solubility of the drug and permeation of topical nonsteroidal anti-inflammatory drugs.

Abstract
The antibacterial efficiency and synergistic mechanisms of novel formulated eugenol entrapped ethosome nanoparticles (ELG-NPs) against fruit anthracnose were investigated. The results showed that concentrations of eugenol and ethanol significantly influenced the particle size and entrapment efficiency of nanoethosome, and the particle size significantly influenced the antibacterial effect. Superior ELG-NPs with optimized process (0.5% eugenol, 2% lecithin, and 30% ethanol) were obtained with a size of 44.21 nm and entrapment efficiency of 82%. ELG-NPs exhibited an antibacterial activity (>93%) against fruit pathogens that was greater than that of free eugenol and showed 100% inhibition of the anthracnose incidence in postharvest loquat after 6 d. The permeability study, first visualized in banana cortex with fluorescent indicators, demonstrated that eugenol delivered to the interior with ELG-NPs was 6-fold higher than that of free eugenol. ELG-NPs showed a satisfactory slow-release and prolonged antibacterial action. This work provides a promising strategy for disease controls in agricultural, food, cosmetic, and medical areas.

Abstract
The aim of the current manuscript was to test the applicability of a nanocomposite system of penetration enhancer vesicles (PEVs) within polymeric in situ forming gel network composed of poloxamer and hyaluronic acid for the intranasal delivery of the antiemetic dimenhydrinate (DMH). PEVs were prepared using phospholipids and labrasol/transcutol/PEG 400 as penetration enhancers, and characterized for entrapment efficiency (EE%), particle size, zeta potential and morphology. The nanocomposite in situ forming gel system was characterized for its sol-gel temperature, viscosity and mucoadhesiveness, and was pharmacodynamically tested on a cisplatin induced emesis model in rats in terms of food, water, kaolin intake and stomach weight content. The selected PEVs formula displayed EE% of 83% for DMH, particle size of 121 nm and a surface charge of 0.83 mV. The selected nanocomposite in situ gelling formula showed a viscosity of 2.13 Pa.S, mucoadhesive force of 0.62 N and DMH controlled release over 6 hours. The pharmacodynamic study showed the superiority of the nanocomposite in situ gelling formula; being administered at a lower dose than the oral marketed formula. The described nanocomposite system proved to be successful for the intranasal delivery of DMH, thus presenting a promising delivery modality for similar antiemetics.

Abstract
Usually the topical delivery of ocular drugs poses a great challenge. Accordingly, the work in this study comprised the use of different hybrids of generally regarded as safe (GRAS) oils and surfactants in order to develop and optimize novel acetazolamide (AZD) entrapped-vesicular systems aiming at improving its ocular delivery and reaching better therapeutic outcomes in the treatment of glaucoma. The phospholipid/cholesterol bilayer of the vesicles was enriched with hybrids of Tween 80, Labrasol, Transcutol and Labrafac lipophile WL in different masses and proportions according to a mixture design viz. D-optimal mixture design. Three models were generated comprising three responses: particles size, percentage of entrapment efficiency and amount of drug released after 24 hours (Q24h). The results demonstrated the ability of the penetration enhancing hybrids in modulating the three responses compared to the conventional liposomes. Transmission electron microscope was used to characterize the selected formulations. Sterilization of selected formulations was carried out using gamma radiation and the effect of gamma radiations on entrapment, particle size and in vitro release were studied. The selected sterilized formulations were tested in-vivo on the eyes of albino rabbits in order to evaluate the efficiency of the novel delivery systems on the intra-ocular pressure reduction (IOP) compared to drug solution and the conventional liposomes. The novel formulations proved their efficiency in reducing the IOP to lower values compared to the conventional liposomes, which pose new successful platform for ocular delivery of AZD and other anti-glaucoma drug analogs.

Abstract
Elastic liposomes have been developed and evaluated as novel topical and transdermal delivery systems. They share some similarities to conventional liposomes but their composition is designed to confer flexibility and elasticity in the lipid bilayer structure. Elastic liposomes are applied non-occluded to the skin and are reported to permeate through the stratum corneum lipid lamellar regions as a result of the hydration or osmotic force in the skin. They have been investigated as drug carriers for a range of small molecules, peptides, proteins, and vaccines, both in vitro and in vivo. Following topical application, structural changes in the stratum corneum have been identified and intact elastic liposomes visualized within the stratum corneum lipid lamellar regions, but evidence of intact liposomes in the deeper viable tissues is limited. The method by which they transport their drug payload into and through the skin has been investigated but remains an area of contention. This chapter provides an overview of the development, characterization, and evaluation of elastic liposomes for delivery into and via the skin.

Abstract
In this work, diclofenac was encapsulated, as sodium salt, in glycerosomes containing 10, 20 or 30% of glycerol in the water phase with the aim to ameliorate its topical efficacy. Taking into account previous findings, glycerosome formulation was modified, in terms of economic suitability, using a cheap and commercially available mixture of hydrogenated soy phosphatidylcholine (P90H). P90H glycerosomes were spherical and multilamellar; photon correlation spectroscopy showed that obtained vesicles were ∼131nm, slightly larger and more polydispersed than those made with dipalmitoylphosphatidylcholine (DPPC) but, surprisingly, they were able to ameliorate the local delivery of diclofenac, which was improved with respect to previous findings, in particular using glycerosomes containing high amount of glycerol (20 and 30%). Finally, this drug delivery system showed a high in vitro biocompatibility toward human keratinocytes.

Abstract
The topical efficacy of baicalin, a natural flavonoid isolated from Scutellaria baicalensis Georgi, which has several beneficial properties, such as antioxidative, antiviral, anti-inflammatory and antiproliferative, is hindered by its poor aqueous solubility and low skin permeability. Therefore, its incorporation into appropriate phospholipid vesicles could be a useful tool to improve its local activity. To this purpose, baicalin at increasing concentrations up to saturation, was incorporated in ultradeformable vesicles, which were small in size (∼67nm), monodispersed (PI<0.19) and biocompatible, regardless of the concentration of baicalin, as confirmed by in vitro studies using fibroblasts. On the other hand, transdermal flux through human epidermis was concentration dependent. The in vivo results showed the significant anti-inflammatory activity of baicalin loaded nanovesicles irrespective of the concentration used, as they were able to reduce the skin damage induced by the phorbol ester (TPA) application, even in comparison with dexamethasone, a synthetic drug with anti-inflammatory properties. Overall results indicate that ultradeformable vesicles are promising nanosystems for the improvement of cutaneous delivery of baicalin in the treatment of skin inflammation.

Abstract
Drug delivery vehicles can influence the topical delivery and the efficacy of an active pharmaceutical ingredient (API). In this study, the influence of Pheroid™ technology, which is a unique colloidal drug delivery system, on the skin permeation and antimelanoma efficacy of 5-fluorouracil were investigated. Lotions containing Pheroid™ with different concentrations of 5-fluorouracil were formulated then used in Franz cell skin diffusion studies and tape stripping. The in vitro efficacy of 5-fluorouracil against human melanoma cells (A375) was investigated using a flow cytometric apoptosis assay. Statistically significant concentrations of 5-fluorouracil diffused into and through the skin with Pheroid™ formulations resulting in an enhanced in vitro skin permeation from the 4.0% 5-fluorouracil lotion (p < 0.05). The stratum corneum-epidermis and epidermis-dermis retained 5-fluorouracil concentrations of 2.31 and 6.69 μg/ml, respectively, after a diffusion study with the 4.0% Pheroid™ lotion. Subsequent to the apoptosis assay, significant differences were observed between the effect of 13.33 μg/ml 5-fluorouracil in Pheroid™ lotion and the effects of the controls. The results obtained suggest that the Pheroid™ drug delivery system possibly enhances the flux and delivery of 5-fluorouracil into the skin. Therefore, using Pheroid™ could possibly be advantageous with respect to topical delivery of 5-fluorouracil.

Abstract
CONTEXT The systemic treatment of onychomycosis has been hampered by the reported side effects of antifungals in addition to the limited blood circulation to the affected nails. Topical ungual treatment would circumvent the limitations of systemic onychomycosis treatment. OBJECTIVE Preparation and characterization of nail penetration enhancer containing nanovesicles (nPEVs) loaded with sertaconazole for topical treatment of onychomycosis. MATERIALS AND METHODS nPEVs were prepared using different nail penetration enhancers (N-acetyl-L-cysteine, thioglycolic acid, thiourea and ethanol) by the thin film hydration method, and characterized for their particle size, zeta potential, entrapment efficiency (EE%), elasticity, viscosity, physical stability and morphology. The selected nPEVs formula and the marketed Dermofix® cream were compared in terms of nail hydration, transungual drug uptake and antifungal activity against Trichophyton rubrum. RESULTS N-acetyl-l-cysteine was the optimum nail penetration enhancer for incorporation within vesicles. nPEVs showed high EE% of sertaconazole ranging from 77 to 95%, a size ranging from 38-538 nm and a zeta potential ranging from +48 to +72 mV. The selected nPEVs formula displayed spherical morphology and good storage stability. Compared to the conventional marketed cream, the selected nPEVs formula showed 1.4-folds higher hydration and drug uptake enhancement into nail clippings. Furthermore, it showed significantly higher zone of inhibition for Trichophyton rubrum (20.9 ± 0.25 mm) than the marketed cream (11.6 ± 0.44 mm). CONCLUSION Nail penetration enhancer containing nanovesicles (nPEVs) present a very promising option, worthy of clinical experimentation on onychomycotic patients.

Abstract
Aim: To study whether the formulation of an antifungal drug in nanovesicular form containing skin penetration enhancer would clinically modulate its therapeutic effectiveness. Materials & methods: Nanovesicles containing different skin penetration enhancers ‘PEVs’ were prepared and loaded with sertaconazole. Penetration-enhancer vesicles were characterized for entrapment efficiency, particle size, zeta potential, elasticity, viscosity, morphology and ex vivo skin deposition. Selected formulae were preliminary tested for clinical efficacy on patients suffering from tinea corporis and tinea versicolor. Results & conclusion: The nanosize of the vesicles, their content of penetration enhancer and their deformable nature are three cornerstones positively influencing the therapeutic outcome of topical antifungal therapy, and hence, can be considered a promising treatment modality for skin fungal diseases.

Abstract
In this study, the effects of ethanol and/or diclofenac on vesicle bilayer structure have been studied. Liposomes with hydrogenated soy phosphatidylcholine, cholesterol and two different concentrations of diclofenac sodium (5 and 10 mg/ml) were obtained. In addition, ethanol was mixed in the water phase at different concentrations (5, 10 and 20 % v/v) to obtain ethosomes. To characterize vesicles, rehological analysis were carried out to investigate the intervesicle interactions, while bilayer structure was evaluated by small- and wide-angle X-ray scattering. Finally, the ethanol and/or diclofenac concentration-dependent ability to improve diclofenac skin delivery was evaluated in vitro. The addition of 20 % ethanol and/or diclofenac led to solid-like ethosome dispersion due to the formation of a new intervesicle structure, as previously found in transcutol containing vesicle dispersions. However, when using 5-10 % of ethanol the induction to form vesicle interconnections was less evident but the simultaneous presence of the drug at the highest concentration facilitated this phenomenon. Ethosomes containing the highest amount of both, drug (10 mg/ml) and ethanol (20 % v/v), improved the drug deposition in the skin strata and in the receptor fluid up to 1.5-fold, relative to liposomes. Moreover this solid-like formulation can easily overcome drawbacks of traditional liquid liposome formulations which undergo a substantial loss at the application site.

Abstract
In this work, phospholipid vesicle-based nanoformulations were developed to deliver antioxidant resveratrol (RSV) to the skin. Penetration enhancer-containing vesicles (PEVs) were prepared adding Oramix™ CG110 or Lauroglycol™ FCC to phosphatidylcholine to favor RSV diffusion through the skin, which was investigated using Franz cells. Vesicles were approximately 100 nm in size, negatively charged and fairly round in shape, as shown via transmission electron microscopy. Nuclear magnetic resonance studies were performed to investigate the RSV/vesicle interactions at the molecular scale, which revealed that RSV was deeply embedded in the bilayer, as shown by the restricted mobility of the drug. Moreover, PEVs improved drug local accumulation 1.7- to 2.1-fold, as compared to the control liposomes. Confocal imaging displayed broadened intercellular spaces in the viable epidermis of PEVs treated skin and high degree of hydration, which are presumably due to the occlusive film formed on the skin surface by the vesicles. These phenomena may be responsible for the higher RSV accumulation achieved when administering PEVs, as compared to control liposomes. Finally, the toxicity of the vesicular formulations was evaluated in vitro against 3T3 fibroblasts, showing no alteration on cell viability after 24h incubation with RSV loaded vesicles. The results from this study suggest that the proposed formulations may be a potential therapeutic alternative to treat skin disorders associated with oxidative stress.

Abstract
OBJECTIVES The present study was aimed at targeting the skin to deliver lidocaine loaded in surfactant/phospholipid vesicles tailored for improved local delivery. The influence of different formulation parameters was explored to maximise drug efficacy. METHODS The vesicles were prepared using a mixture of soy lipids (Phospholipon 50) and a surfactant with penetration-enhancing properties (Oramix CG110, Labrasol, Labrafac PG or Labrafac CC), and loaded with lidocaine. The formulations were analysed in detail by cryo-TEM, SAXS, Turbiscan Lab, and tested in permeation experiments through new born pig skin, as a function of the chemical form and concentration of lidocaine (i.e. free base or salt, 12.5 or 25 mg/ml). KEY FINDINGS Small, spherical vesicles with good entrapment efficiency and exceptional long-term stability were produced. The lamellar organisation was affected by either the surfactant or the lidocaine form used. Permeation studies highlighted that the co-incorporation of lidocaine base + hydrochloride allowed the achievement of a superior deposition in the skin layers, especially when surfactant vesicles were used, as their content was presumably saturated with the maximum amount of loadable anaesthetic. CONCLUSIONS The proposed systems based on surfactant/phospholipid vesicles co-loaded with both lidocaine forms are an effective approach for improving its local delivery.

Abstract
Quercetin was incorporated in glycerosomes, new phospholipid-glycerol vesicles, and their protective effect against oxidative stress skin damages was extensively evaluated. In particular, the concentration-dependent effect of glycerol (from 10 to 50%) on vesicle suitability as cutaneous carriers of quercetin was carefully assessed. All vesicles were unilamellar and small in size (∼80-110 nm), as confirmed by cryo-TEM observation, with a drug incorporation efficiency ranging between 81 and 91%. SAXS studies, performed to investigate the bilayer arrangement, indicated a strong, dose-dependent interaction of glycerol with the polar portions of the phospholipid molecules, while quercetin did not significantly change the bilayer packing. In vitro studies on newborn pig skin underlined the concentration-dependent ability of glycerosomes to promote quercetin accumulation in the different layers, also confirmed by confocal microscopic observation of skin treated with fluorescent vesicles. Quercetin incorporated into liposomal and glycerosomal nanoformulations showed a strong ability to scavenge free radicals (DPPH test) and protect human keratinocytes in vitro against hydrogen peroxide damage. Moreover, quercetin-loaded vesicles were avidly taken up by keratinocytes in vitro. Overall, results indicate 40 and 50% glycerosomes as promising nanosystems for the improvement of cutaneous quercetin delivery and keratinocyte protection against oxidative stress damage.

Abstract
This review highlights the key role of NMR techniques in demonstrating the molecular aspects of the self-assembly of surfactant molecules that nowadays constitute the basic knowledge which modern nanoscience relies on. The aim is to provide a tutorial overview. The story of a rigorous scientific approach to understand self-assembly in surfactant systems and biological membranes starts in the early seventies when the progresses of SAXRD and NMR technological facilities allowed to demonstrate the existence of ordered soft matter, and the validity of Tanford approach concerning self-assembly at a molecular level. Particularly, NMR quadrupolar splittings, NMR chemical shift anisotropy, and NMR relaxation of dipolar and quadrupolar nuclei in micellar solutions, microemulsions, and liquid crystals proved the existence of an ordered polar-apolar interface, on the NMR time scale. NMR data, rationalized in terms of the two-step model of relaxation, allowed to quantify the dynamic aspects of the supramolecular aggregates in different soft matter systems. In addition, NMR techniques allowed to obtain important information on counterion binding as well as on size of the aggregate through molecular self-diffusion. Indeed NMR self-diffusion proved without any doubt the existence of bicontinuous microemulsions and bicontinuous cubic liquid crystals, suggested by pioneering and brilliant interpretation of SAXRD investigations. Moreover, NMR self-diffusion played a fundamental role in the understanding of microemulsion and emulsion nanostructures, phase transitions in phase diagrams, and particularly percolation phenomena in microemulsions. Since the nineties, globalization of the knowledge along with many other technical facilities such as electron microscopy, particularly cryo-EM, produced huge progresses in surfactant and colloid science. Actually we refer to nanoscience: bottom up/top down strategies allow to build nanodevices with applications spanning from ICT to food technology. Developments in the applied fields have also been addressed by important progresses in theoretical skills aimed to understand intermolecular forces, and specific ion interactions. Nevertheless, this is still an open question. Our predictive ability has however increased, hence more ambitious targets can be planned. Nanomedicine represents a major challenging field with its main aims: targeted drug delivery, diagnostic, theranostics, tissue engineering, and personalized medicine. Few recent examples will be mentioned. Although the real applications of these systems still need major work, nevertheless new challenges are open, and perspectives based on integrated multidisciplinary approaches would enable both a deeper basic knowledge and the expected advances in biomedical field.

Abstract
PURPOSE To develop quercetin-loaded phospholipid vesicles, namely liposomes and PEVs (Penetration Enhancer-containing Vesicles), and to investigate their efficacy on TPA-induced skin inflammation. METHODS Vesicles were made from a mixture of phospholipids, quercetin and polyethylene glycol 400 (PEG), specifically added to increase drug solubility and penetration through the skin. Vesicle morphology and self-assembly were probed by Cryo-Transmission Electron Microscopy and Small/Wide Angle X-ray Scattering, as well as the main physico-chemical features by Light Scattering. The anti-inflammatory efficacy of quercetin nanovesicles was assessed in vivo on TPA-treated mice dorsal skin by the determination of two biomarkers: oedema formation and myeloperoxidase activity. The uptake of vesicles by 3T3 fibroblasts was also evaluated. RESULTS Small spherical vesicles were produced. Their size and lamellarity was strongly influenced by the PEG content (0%, 5%, 10% v/v). The administration of vesicular quercetin on TPA-inflamed skin resulted in an amelioration of the tissue damage, with a noticeable attenuation of oedema and leukocyte infiltration, especially using 5% PEG-PEVs, as also confirmed by confocal microscopy. In vitro studies disclosed a massive uptake and diffusion of PEVs in dermal fibroblasts. CONCLUSIONS The proposed approach based on quercetin vesicular formulations may be of value in the treatment of inflammatory skin disorders.

Abstract
The purpose of this study was to develop a new delivery system capable of improving bioavailability and controlling release of hydrophilic drugs. Metformin-loaded liposomes were prepared and to improve their stability surface was coated with chitosan cross-linked with the biocompatible β-glycerolphosphate. X-ray diffraction, differential scanning calorimetry, as well as rheological analysis were performed to investigate interactions between chitosan and β-glycerolphosphate molecules. The entrapment of liposomes into the chitosan-β-glycerolphosphate network was assessed by scanning electron microscopy and transmission electron microscopy. Swelling and mucoadhesive properties as well as drug release were evaluated in vitro while the drug oral bioavailability was evaluated in vivo on Wistar rats. Results clearly showed that, compared to control, the proposed microcomplexes led to a 2.5-fold increase of metformin T(max) with a 40% augmentation of the AUC/D value.
