Current Advances in Lipid Nanosystems Intended for Topical and Transdermal Drug Delivery Applications. Pharmaceutics 2023; 15:pharmaceutics15020656. [PMID: 36839978 PMCID: PMC9967415 DOI: 10.3390/pharmaceutics15020656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 01/29/2023] [Accepted: 01/31/2023] [Indexed: 02/18/2023] Open
Abstract
Skin delivery is an exciting and challenging field. It is a promising approach for effective drug delivery due to its ease of administration, ease of handling, high flexibility, controlled release, prolonged therapeutic effect, adaptability, and many other advantages. The main associated challenge, however, is low skin permeability. The skin is a healthy barrier that serves as the body's primary defence mechanism against foreign particles. New advances in skin delivery (both topical and transdermal) depend on overcoming the challenges associated with drug molecule permeation and skin irritation. These limitations can be overcome by employing new approaches such as lipid nanosystems. Due to their advantages (such as easy scaling, low cost, and remarkable stability) these systems have attracted interest from the scientific community. However, for a successful formulation, several factors including particle size, surface charge, components, etc. have to be understood and controlled. This review provided a brief overview of the structure of the skin as well as the different pathways of nanoparticle penetration. In addition, the main factors influencing the penetration of nanoparticles have been highlighted. Applications of lipid nanosystems for dermal and transdermal delivery, as well as regulatory aspects, were critically discussed.

Abstract
This investigation aimed to design, develop, and optimize intranasal nanoemulsion for brain targeted delivery of lurasidone hydrochloride for the management and treatment of schizophrenia. The design of experiment supported optimization of high-pressure homogenization (HPH) process was executed for the manufacturing of lurasidone loaded nanoemulsion. The nanoemulsion comprising of lurasidone hydrochloride (10 mg/mL), 20% Oilmix, 25% surfactant and, 55% aqueous phase (w/w) was processed with HPH at optimized conditions to get droplet size in the nano range. The droplet size of optimized nanoemulsion was found to be 48.07 ± 3.29 nm with a polydispersity index of 0.31 ± 0.01. The optimized translucent nanoemulsion (% transmittance of 88.56 ± 2.47) was found to be non-toxic to sheep nasal mucosa and stable for six months. The results of ex vivo diffusion study revealed the improvement in drug diffused by mucoadhesive nanoemulsion (MLNE) (1.41 × 10-4 ± 1.11 × 10-5 cm2/min) as compared to the solution (1.15 × 10-4 ± 1.35 × 10-5 cm2/min). The results of pharmacodynamic studies in mice uncover the highest inhibition of compulsive behavior (64.63%) and spontaneous locomotor activity (60.87%) shown by MLNE. This may be due to increased bioavailability in a brain, and possibly confirms the potential of nanoemulsion in targeting the brain through nasal route in the treatment of schizophrenia.

Abstract
In this study, the feasibility of transcutaneous immunization using different needle-geometries dissolving microneedle array (DMNA) were investigated as drug carriers for ovalbumin (OVA) preparations. A two-step molding process was used in which needles were loaded with OVA. The microneedles displayed a geometry and dimensions consistent with the main molds. DMNA with different needle-geometries were compared and characterized. Drug loading of the prepared DMNAs reached ~100 μg measured via BCA assay. The stability of OVA in the DMNAs was investigated by SDS-PAGE electrophoresis and showed that the OVA encapsulated in the DMNAs was stable during preparation. The immune responses induced by the DMNAs and hypodermic needle-based injections were compared through in vivo immunoglobulin G (IgG) production assays. OVA-loaded DMNAs also induced stronger immune responses compared to hypodermic needle-based injections. In conclusion, these results suggest that: (1) the needle-morphology of DMNAs influences their mechanical properties, insertion capacity, and dissolution, thus affecting the immune response; (2) Cone-DMNAs are optimal for transcutaneous immunization. These data provide a theoretical basis for the use of transcutaneous immunization of DMNAs for vaccine development.

Abstract
BACKGROUND Rice bran oil and soy protein nanoparticles (SPNs) may be considered as novel functional food ingredients for soy yogurt production. Formulation of soy yogurt with SPNs and rice bran oil, which has significant physiological functions, will convert them into functional food products. This study was conducted to develop rice bran oil-based soy protein nanoparticles emulsion (SPNE) and to evaluate physical properties, antioxidant activities, oxidative stability and microbiological load as well as textural attributes of SPNs incorporated yogurt (SPNY) during storage at 4 °C for 45 days. RESULTS SPNs were prepared from soy protein isolate of defatted soy flour. Solubilization, crystallization and ultrasonication was carried out six times. After the sixth cycle of repeated solubilizing, crystallization and ultrasonication, the size of nano protein was reduced to 72.42 ± 0.22 nm from 586.72 ± 0.75 nm (after first cycle). Viscosity, penetration values and water-holding capacity of SPNs added to yogurt were decreased with increase in reduction size of SPNs. SPNs added to yogurt exhibited greater antiradical scavenging ability and ferric reducing antioxidant property than control yogurt. Fortified soy yogurt had significant higher oxidative stability and proteolytic activity. CONCLUSION Fortification of non-dairy food products with SPNs, which has significant physiological functions, convert conventional soy yogurt into functional food products. © 2019 Society of Chemical Industry.

Abstract
Advancements in biotechnology and protein engineering expand the availability of various therapeutic proteins including vaccines, antibodies, hormones, and growth factors. In addition, protein drugs hold many therapeutic advantages over small synthetic drugs in terms of high specificity and activity. This has led to further R&D investment in protein-based drug products and an increased number of drug approvals for therapeutic proteins. However, there are many biological and biopharmaceutical obstacles inherent to protein drugs including physicochemical and enzymatic destabilization, which limit their development and clinical application. Therefore, effective formulations of therapeutic proteins are needed to overcome the various physicochemical and biological barriers. In current medical practice, protein drugs are predominantly available in injectable formulations, which have disadvantages including pain, the possibility of infection, high cost, and low patient compliance. Consequently, non-invasive drug delivery systems for therapeutic proteins have gained great attention in the research and development of biomedicines. Therefore, this review covers the various formulation approaches to optimizing the delivery properties of protein drugs with an emphasis on improving bioavailability and patient compliance. It provides a comprehensive update on recent advancements in nanotechnologies with regard to non-invasive protein drug delivery systems, which is also categorized by the route of administrations including oral, nasal, transdermal, pulmonary, ocular, and rectal delivery systems.

Abstract
Atorvastatin (ATV) may support mesenchymal stem cells (MSC) survival in post-infarct myocardium (MI) as inflammatory reactions, oxidative stress and hypoxia condition get started in such tissues after damage. However, limited aqueous insolubility and rapid first-pass metabolism reduce the systemic availability of ATV. The aim of the present investigation was to develop ATV loaded nanoparticles (ATVNPs) which might ensure the maximum availability of ATV in systemic circulation for longer duration and to strengthen the support to MSC survival. ATVNPs were synthesized using double emulsion solvent evaporation method and characterized as spherical shape, positive charged, nanoparticles of uniform size distribution and higher entrapment efficiency. ATVNPs were non-cytotoxic and showed sustained release (up to 28 days). Assessment of cardiac function (in terms of echocardiographic and left heart catheterization parameters) and cytokines estimation revealed efficient improvement in post-infarct myocardium condition of rat. In conclusion, ATVNP was developed successfully that may ensure safe, cost effective, and efficacious treatment of post-infarct myo-cardium when compared with that of MSC alone and MSC supplemented with ATV solution.

Abstract
Nanosystems such as microemulsions (ME) and nanoemulsions (NE) offer considerable opportunities for targeted drug delivery to and via the skin. ME and NE are stable colloidal systems composed of oil and water, stabilised by a mixture of surfactants and cosurfactants, that have received particular interest as topical skin delivery systems. There is considerable scope to manipulate the formulation components and characteristics to achieve optimal bioavailability and minimal skin irritancy. This includes the incorporation of established chemical penetration enhancers to fluidize the stratum corneum lipid bilayers, thus reducing the primary skin barrier and increasing permeation. This review discusses nanosystems with utility in skin delivery and focuses on the composition and characterization of ME and NE for topical and transdermal delivery. The mechanism of skin delivery across the stratum corneum and via hair follicles is reviewed with particular focus on the influence of formulation.

Abstract
In the recent decade, skin delivery (topical and transdermal) has gained an unprecedented popularity, especially due to increased incidences of chronic skin diseases, demand for targeted and patient compliant delivery, and interest in life cycle management strategies among pharmaceutical companies. Literature review of recent publications indicates that among various skin delivery systems, lipid-based delivery systems (vesicular carriers and lipid particulate systems) have been the most successful. Vesicular carriers consist of liposomes, ultradeformable liposomes, and ethosomes, while lipid particulate systems consist of lipospheres, solid lipid nanoparticles, and nanostructured lipid carriers. These systems can increase the skin drug transport by improving drug solubilization in the formulation, drug partitioning into the skin, and fluidizing skin lipids. Considering that lipid-based delivery systems are regarded as safe and efficient, they are proving to be an attractive delivery strategy for the pharmaceutical as well as cosmeceutical drug substances. However, development of these delivery systems requires comprehensive understanding of physicochemical characteristics of drug and delivery carriers, formulation and process variables, mechanism of skin delivery, recent technological advancements, specific limitations, and regulatory considerations. Therefore, this review article encompasses recent research advances addressing the aforementioned issues.

Abstract
CONTEXT Gastric carcinoma (GC) is one of the most common cancers and the second most frequent cause of cancer-related deaths. Chemotherapy is an important therapeutic modality for GC. However, chemoresistance limited its success rate. Combination chemotherapy is often applied to prevent drug-induced resistance in cancers. OBJECTIVE The aim of this study is to evaluate whether the co-delivery of etoposide (ETP) and curcumin (CUR) with one nanoparticle can result in synergistic effects of both drugs. METHODS ETP- and CUR-loaded nanostructured lipid carriers (ETP-CUR-NLC) were prepared by the solvent injection technique. Their average size, zeta potential and drug loading were evaluated. Human gastric cancer cell lines (SGC7901 cells) were used for the testing of in vitro cytotoxicity studies, and in vivo anti-tumor efficacies of the carriers were evaluated on mice bearing SGC7901 cells xenografts. RESULTS ETP-CUR-NLC has a particle size of 114 nm, EPT-loading quantity of 83% and CUR-loading quantity of 82%. ETP-CUR-NLC displayed high cytotoxicity and enhanced antitumor activity in vitro and in vivo. Meanwhile, ETP-CUR-NLC displayed low cytotoxicity in normal tissues in vivo. DISCUSSION AND CONCLUSION The results demonstrate that ETP-CUR-NLC can achieve impressive anti-tumor activity. By combining CUR, an effective NF-κB inhibitor, with ETP, a powerful anticancer drug, in NLC, we could improve the therapeutic efficacy in cancer treatments. Our results showed that such co-loaded delivery systems could serve as a promising therapeutic approach to improve clinical outcomes against various malignancies.

Abstract
The purpose of this study was to explore the enhancing effects and the mechanism of monocyclic monoterpene penetration enhancers (menthol and menthone) on the transdermal absorption of ligustrazine hydrochloride (LH). Franz-type diffusion cells were used to determine percutaneous parameters of LH in vitro and surface changes of porcine skin were studied by a scanning electron microscope (SEM). The effects of promoters on the biophysical natures of stratum corneum (SC) were researched by Fourier transform-infrared (FT-IR). Penetration parameters of menthol (p < 0.01) and menthone groups (p < 0.05) were greater than those of the control; morphological changes of skin monitored by SEM demonstrated that the menthone group had the most disruption and desquamation of SC flakes, which resulted from extracted lipids. FT-IR measurements showed menthone had the greatest changes in peak shift and peak area, which resulted from C-H stretching vibrations of SC lipids. The results suggest that the penetration mechanism might include disturbing and extracting SC lipids and the hydrogen bond connection.

Abstract
CONTEXT Combination therapies provide a potential solution to address the tumor heterogeneity and drug resistance issues by taking advantage of distinct mechanisms of action of the multiple therapeutics. OBJECTIVE To design arginine-glycineaspartic acid (RGD) modified lipid-coated nanoparticles (NPs) for the co-delivery of the hydrophobic drugs against hepatocellular carcinoma (HCC). MATERIALS AND METHODS RGD modified lipid-coated PLGA NPs were developed for the targeted delivery of both sorafenib (SRF) and quercetin (QT) (RGD-SRF-QT NPs). Chemical-physical characteristics and release profiles were evaluated. In vitro cell viability assays were carried out on HCC cells. In vivo antitumor efficacies were evaluated in HCC animal model. RESULTS AND DISCUSSION The combination of SRF and QT formulations was more effective than the single drug formulations in both NPs and solution groups. RGD-SRF-QT NPs achieved the most significant tumor growth inhibition effect in vitro and in vivo. CONCLUSION The resulting NPs could provide a promising platform for co-delivery of multiple anticancer drugs for achievement of combinational therapy and could offer potential for enhancing the therapeutic efficacy on HCC.

Abstract
The many factors impacting the efficacy of a vaccine can be broadly divided into three categories: features of the vaccine itself, including immunogen design, vaccine type, formulation, adjuvant and dosing; individual variations among vaccine recipients and vaccine administration-related parameters. While much literature exists related to vaccines, and recently systems biology has started to dissect the impact of individual subject variation on vaccine efficacy, few studies have focused on the role of vaccine administration-related parameters on vaccine efficacy. Parenteral and mucosal vaccinations are traditional approaches for licensed vaccines; novel vaccine delivery approaches, including needless injection and adjuvant formulations, are being developed to further improve vaccine safety and efficacy. This review provides a brief summary of vaccine administration-related factors, including vaccination approach, delivery route and method of administration, to gain a better understanding of their potential impact on the safety and immunogenicity of candidate vaccines.

Abstract
The aim of this work is to develop a curcumin nanoemulsion for transdermal delivery. The incorporation of curcumin inside a nanoglobul should improve curcumin stability and permeability. A nanoemulsion was prepared by the self-nanoemulsification method, using an oil phase of glyceryl monooleate, Cremophor RH40 and polyethylene glycol 400. Evaluation of the nanoemulsion included analysis of particle size, polydispersity index, zeta potential, physical stability, Raman spectrum and morphology. In addition, the physical performance of the nanoemulsion in Viscolam AT 100P gel was studied. A modified vertical diffusion cell and shed snake skin of Python reticulatus were used to study the in vitro permeation of curcumin. A spontaneously formed stable nanoemulsion has a loading capacity of 350 mg curcumin/10 g of oil phase. The mean droplet diameter, polydispersity index and zeta potential of optimized nanoemulsion were 85.0 ± 1.5 nm, 0.18 ± 0.0 and -5.9 ± 0.3 mV, respectively. Curcumin in a nanoemulsion was more stable than unencapsulated curcumin. Furthermore, nanoemulsification significantly improved the permeation flux of curcumin from the hydrophilic matrix gel; the release kinetic of curcumin changed from zero order to a Higuchi release profile. Overall, the developed nanoemulsion system not only improved curcumin permeability but also protected the curcumin from chemical degradation.
