Abstract
Clobetasol Propionate is a highly strong corticosteroid that is used in a variety of topical medication formulations, including foam, ointment, lotion, spray and shampoo; with a dosage strength of 0.05% (w/w). The goal of this research was to identify and characterize a substantial unknown impurity (UK) detected during the stability testing of a Clobetasol Propionate foam pharmaceutical product in accelerated conditions (40°C and 75% relative humidity). Developing a single, robust and accurate HPLC method that is LC-MS compatible for quantifying all 14 potential Clobetasol Propionate impurities in therapeutic drugs is another goal. Preparative column chromatography was used to separate the impurity, and spectroscopic techniques like IR, NMR and MS were used to characterize its structure. The structure of isolated UK was effectively characterized and defined using spectroscopic data evaluation. The chromatographic method has also been validated according to the International Conference on Hominization's Q (2) quality guidelines. The isolated and characterized impurity had the same equivalence as the impurity found during stability testing. Precision, accuracy, linearity, robustness and ruggedness are all met in the method validation data.

Abstract
Inflammatory dermatoses represent a global problem with increasing prevalence and recurrence among the world population. Topical glucocorticoids (GCs) are the most commonly used anti-inflammatory drugs in dermatology due to a wide range of their therapeutic actions, which, however, have numerous local and systemic side effects. Hence, there is a growing need to create new delivery systems for GCs, ensuring the drug localization in the pathological site, thus increasing the effectiveness of therapy and lowering the risk of side effects. Here, we propose a novel topical particulate formulation for the GC clobetasol propionate (CP), based on the use of porous calcium carbonate (CaCO3) carriers in the vaterite crystalline form. The designed carriers contain a substantially higher CP amount than conventional dosage forms used in clinics (4.5% w/w vs. 0.05% w/w) and displayed a good biocompatibility and effective cellular uptake when studied in fibroblasts in vitro. Hair follicles represent an important reservoir for the GC accumulation in skin and house the targets for its action. In this study, we demonstrated successful delivery of the CP-loaded carriers (CP-CaCO3) into the hair follicles of rats in vivo using optical coherent tomography (OCT). Importantly, the OCT monitoring revealed the gradual intrafollicular degradation of the carriers within 168 h with the most abundant follicle filling occurring within the first 48 h. Biodegradability makes the proposed system especially promising when searching for new CP formulations with improved safety and release profile. Our findings evidenced the great potential of the CaCO3 carriers in improving the dermal bioavailability of this poorly water-soluble GC.

Abstract
Atopic dermatitis is a prevalent chronic skin inflammation affecting 2.1 to 4.1% of adults globally. The complexity of its pathogenesis and the relapsing nature make it challenging to treat. Current treatments follow European Academy of Dermatology and Venerology guidelines, but advanced cases with recurring lesions lack effective therapies. To address this gap, researchers are exploring nanotechnology for targeted drug delivery. Nanoparticles offer benefits such as improved drug retention, stability, controlled release and targeted delivery through the disrupted epidermal barrier. This integrated review evaluates the current state of AD treatment and highlights the potential of novel nano-formulations as a promising approach to address the disease.

[PMID: 35214115 PMCID: PMC8877216 DOI: 10.3390/pharmaceutics14020383] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Revised: 02/06/2022] [Accepted: 02/08/2022] [Indexed: 02/06/2023] Open
Abstract
Dermal disorders such as psoriasis and eczema are associated with modifications in the chemical and molecular composition of the skin. Clobetasol propionate (CP), a superpotent topical glucocorticoid, is widely used for the therapeutic management of various skin conditions, owing to its strong anti-inflammatory, antipruritic, vasoconstrictive, and antiproliferative activities. Safety studies demonstrated that CP is safer for a shorter period, however, with prolonged application, it shows secondary side effects such as photosensitivity, Cushing-like syndrome, allergic contact dermatitis, osteonecrosis, hypopigmentation, steroid acne, and skin atrophy. Therefore, the US FDA (United States Food and Drug Administration) has restricted the usage of CP to not more than 15 days. Research scientists addressed its several formulations and drug delivery issues, such as low water solubility, less stability, photodegradation, and poor absorption, by incorporating them into novel nanobased delivery platforms. With the utilization of these technologies, these drawbacks of CP have been resolved to a large extent to reestablish this moiety. This article explores the physicochemical properties and mechanism of action of CP. Additionally, an attempt has been made to discover and highlight the possible features of the novel nanosystems, including nanoemulsions, nanosponges, solid lipid nanoparticles, nanostructured lipid carriers, and nanogels, reported for CP. The stability and safety concerns of CP, along with its commercial status, are also discussed.

Abstract
Lipid-polymer hybrid nanoparticles (LPNs) exhibit several advantages over polymeric and non-polymeric systems in terms of improved drug loading, controlled release, stability, and cellular uptake. Herein we report a scalable and stable monolithic lipid-polymer hybrid nanoparticles (LPNs) consisting of a combination of lipids (solid and liquid) and an amphiphilic copolymer, mPEG-PLA. Clobetasol propionate, a topical corticosteroid, was encapsulated in the hydrophobic core of these LPNs that showed spherical shaped particles with a z-average size of 94.8 nm (PDI = 0.213) and encapsulation efficiency of 84.3%. These clobetasol loaded LPNs (CP/LPNs) were formulated into a topical hydrogel using carbopol 974P. CP/LPNs gel showed a sustained in vitro clobetasol release for 7 days with no burst release and 6 month stability at 2-8°C and room temperature. Further, CP/LPNs showed an improved cellular uptake with significant growth inhibition of HaCaT cells. In ex vivo studies, these LPNs penetrated into the viable epidermis and dermis region of the psoriatic skin with undetectable quantities leaching to the reservoir. Further, the topical application of CP/LPNs gel on Swiss albino mice with psoriasis-like inflammation showed negligible leaching of clobetasol into the systemic circulation. Efficacy assessment showed significantly improved PASI score, reduced skin damage and proliferation after treatment with CP/LPNs gel as compared to marketed product (Clobetamos™). Collectively, the enhanced cellular uptake, high skin penetration with increased skin retention, and improved efficacy demonstrate the potential of these LPNs for future clinical application.

Abstract
OBJECTIVES A previous study reported that the hexane fraction (HF) obtained from Pereskia aculeata leaves showed promising topical anti-inflammatory activity. Intending its future use in clinical practice, a herbal medicine cream named INFLATIV was developed. Its anti-inflammatory and antipsoriatic potential were investigated. INFLATIV was subjected to preliminary accelerated stability tests and to a degradation profile assessment. METHODS INFLATIV was prepared at 6% and 12%. The anti-inflammatory activity was assessed by croton oil single and multiple application challenge in mice. Mouse tail test was used for antipsoriatic potential investigation. Cutaneous atrophy test was performed. Preliminary accelerated stability tests were performed together with a degradation profile by GC-MS analysis. KEY FINDINGS The anti-inflammatory activity shown by INFLATIV was comparable to dexamethasone. However, the skin atrophy caused by that drug was not observed. INFLATIV modified skin parakeratotic differentiation into orthokeratosis, which revealed its antipsoriatic potential. The ingredients used were suitable to carry the bioactives as they were well permeated by the skin. The preliminary accelerated stability tests indicated that INFLATIV 6% is more stable than 12%. CONCLUSIONS The results demonstrated the relevant therapeutic and marketing potentials of INFLATIV, which is likely to be further evaluated in clinical trials for drug registration process with regulatory agencies.

Abstract
The NF-κB and interferon antiviral signaling pathways play pivotal roles in inflammatory and innate immune responses. The LUBAC ubiquitin ligase complex, composed of the HOIP, HOIL-1L, and SHARPIN subunits, activates the canonical NF-κB pathway through Met1-linked linear ubiquitination. We identified small-molecule chemical inhibitors of LUBAC, HOIPIN-1 and HOIPIN-8. Here we show that HOIPINs down-regulate not only the proinflammatory cytokine-induced canonical NF-κB pathway, but also various pathogen-associated molecular pattern-induced antiviral pathways. Structural analyses indicated that HOIPINs inhibit the RING-HECT-hybrid reaction in HOIP by modifying the active Cys885, and residues in the C-terminal LDD domain, such as Arg935 and Asp936, facilitate the binding of HOIPINs to LUBAC. HOIPINs effectively induce cell death in activated B cell-like diffuse large B cell lymphoma cells, and alleviate imiquimod-induced psoriasis in model mice. These results reveal the molecular and cellular bases of LUBAC inhibition by HOIPINs, and demonstrate their potential therapeutic uses. Daisuke Oikawa et al. provide structural insights into how small-molecule inhibitors of LUBAC ubiquitin ligase, HOIPINs, bind to LUBAC. They find that HOIPINs trigger apoptosis in lymphoma cells and alleviate psoriasis in mice, suggesting the potential therapeutic utility of HOIPINs.

Abstract
Psoriasis is a multifactorial skin disease involving abnormal cell proliferation and inflammation; an efficacious topical treatment is yet to be identified. A formulation containing 1% Naltrexone HCl in XemaTop™ base was compounded, characterized and evaluated in vitro as a possible treatment for psoriasis. A three-dimensional psoriasis tissue model was exposed to the formulation for 2 or 5 days and analyzed for the level of markers of cellular proliferation, and inflammatory cytokine IL-6. Using immunohistochemical staining, the level of Ki67 protein significantly decreased in the drug-treated tissues. Western blot analysis showed 86% and 53% down-regulation of other proliferation markers PCNA and CYCLIN D1, respectively, after 5-day exposure. The pro-survival Wnt/β-catenin pathway was compromised as indicated by 57% decrease in the level of β-CATENIN and down-regulation of its down-stream targets including CYCLIN D1 (decreased by 53%), c-MYC (63%), c-JUN (92%) and MET (96%) proteins. Likewise, the PI3K/AKT/mTOR pathway was significantly inhibited by 1% Naltrexone HCl in XemaTop™, suggesting protein synthesis was affected. The production of IL-6 was inhibited by 70% in drug-treated tissues. These results suggest that the compounded drug is efficacious in down-regulating molecular markers associated with the pathogenesis of psoriasis. Low-dose Naltrexone in XemaTop™ was stable within 180 days when stored under refrigerated or ambient conditions. These results provide a basis for a clinical evaluation of 1% Naltrexone HCl in XemaTop™ in psoriasis patients.

Abstract
Triamcinolone acetonide (TCA) abuse in cosmetics is a common phenomenon. A rapid lateral flow immunochromatographic assay (ICA) was developed for the quantitative detection of TCA using a probe based on upconversion luminescence nanoparticles. Lanthanide-doped upconversion nanoparticles (UCNPs) were synthesized in a system comprising water and ethylene glycol, and a silicon dioxide layer was covered at the carboxyl site. A binding site protection strategy was used to decrease the background signal of UCNPs-ICA. Using dexamethasone derivative as a coating antigen, the optimal UCNPs-ICA exhibits good dynamic linear detection for TCA in the range 1.0-100 ng mL-1 with a median inhibitory concentration of 9.8 ng mL-1. The detection limits for TCA in a cosmetic sample are 20 μg kg-1. The pretreatment of samples only needs dilution with water, suggesting the assay can quantitate TCA on-site using a portable upconversion luminescence reader with a cumulative analysis time of only 10 min.

Abstract
BACKGROUND Corticosteroids remains compound of choice for topical treatment of psoriasis. Several side effects associated with chronic application of corticosteroids limit its uses. Hence, there is a need to find a safe and effective alternative agent for psoriasis treatment. PURPOSE The study aimed to investigate the in vitro and in vivo efficacy of petroleum ether extract of Annona squamosa seeds (ASO) as an antipsoriatic agent. The toxicity profile of ASO and its effect on psoriasis-induced inflammation has also been determined. METHODS Physicochemical characterization was performed to determine constituents of ASO. Anti-proliferative activity of ASO was studied by Sulforhodamine B (SRB) assay using HaCaT cell lines. Oxazolone-induced psoriasis in female Balb/C mice was used as an animal model for investigating in vivoefficacy of ASO. Inflammatory markers were analyzed by immunohistochemical staining of mice ears. Safety profile of ASO was confirmed by performing acute dose dermal toxicity and repeated dose dermal toxicity testing. RESULTS Predominant presence of polyunsaturated fatty acids viz. linoleic acid and oleic acid in ASO was confirmed by 1H NMR, 13C NMR and GC-MS analysis. The petroleum ether extract of Annona squamosa seeds showed inhibition of cell proliferation of keratinocytes (HaCaT cells). The growth inhibitory property of ASO was significantly higher than that was observed in presence of corticosteroid, clobetasol propionaste (CP). Application of ASO to the ears of Balb/C mice with oxazolone induced psoriasis showed marked reduction in erythema and edema, which was comparable to treatment with 0.05% CP cream. The increased levels of cytokines IL6, IL17, TNF-α, INF-γ, GMCSF, and infiltration of CD4 T cells observed in psoriasis lesions were decreased upon application of ASO. Acute and repeated dermal toxicity studies of ASO did not reveal any adverse events affirming the safety of ASO. CONCLUSION The present data has demonstrated that ASO is a safe and effective anti-psoriatic agent when tested in animal models. The efficacy of ASO in preclinical studies could further be exploited for the development of potential novel topical antipsoriatic agent for therapy in humans.

Abstract
Topical therapy as monotherapy is useful in psoriasis patients with mild disease. Topical agents are also used as adjuvant for moderate-to-severe disease who are being concurrently treated with either ultraviolet light or systemic medications. Emollients are useful adjuncts to the treatment of psoriasis. Use of older topical agents such as anthralin and coal tar has declined over the years. However, they are cheaper and can still be used for the treatment of difficult psoriasis refractory to conventional treatment. Salicylic acid can be used in combination with other topical therapies such as topical corticosteroids (TCS) and calcineurin inhibitors for the treatment of thick limited plaques to increase the absorption of the latter into the psoriatic plaques. Low- to mid-potent TCS are used in facial/flexural psoriasis and high potent over palmoplantar/thick psoriasis lesions. The addition of noncorticosteroid treatment can also facilitate the avoidance of long-term daily TCS. Tacrolimus and pimecrolimus can be used for the treatment of facial and intertriginous psoriasis. Tazarotene is indicated for stable plaque psoriasis usually in combination with other therapies such as TCS. Vitamin D analogs alone in combination with TCS are useful in stable plaques over limbs and palmoplantar psoriasis. Topical therapies for scalp psoriasis include TCS, Vitamin D analogs, salicylic acid, coal tar, and anthralin in various formulations such as solutions, foams, and shampoos. TCS, vitamin D analogs, and tazarotene can be used in the treatment of nail psoriasis.

Reformulations of well-known active ingredients in the topical treatment of psoriasis vulgaris can improve clinical outcomes for patients. J Eur Acad Dermatol Venereol 2017; 31:1271-1284.

Abstract
Although the majority of patients with psoriasis vulgaris are treated exclusively with topical therapies, research to develop more effective topical therapies that are associated with higher patient satisfaction has lagged behind the development of systemic agents. The aim of this literature review was to determine whether there is documented evidence that applying an innovative approach to improving the formulation of active ingredients commonly used in the topical treatment of psoriasis can have a positive effect on clinical outcomes and patient-reported outcomes (PROs). The Embase and PubMed databases were searched for articles published between 2001 and 2016 that made direct head-to-head comparisons of different formulations of an active pharmaceutical ingredient (API), focusing on clinical outcomes and PROs. In total, 22 publications on APIs or API combinations met the eligibility criteria (19 head-to-head clinical trials, one pooled analysis, one health-economic modelling study and one systematic review). Significant clinical benefit associated with the use of a reformulated API over an older formulation was reported in three trials of clobetasol propionate, one trial of calcipotriol, three trials of betamethasone and five trials/pooled analyses of calcipotriol/calcipotriene + betamethasone dipropionate (Cal/BD) formulations. Significantly improved PROs associated with the use of a reformulated API over an older formulation were reported in three trials of clobetasol propionate, one trial of betamethasone valerate and two trials of Cal/BD formulations. These results demonstrate that the innovative reformulation of APIs used in the treatment of psoriasis can produce therapies that attain significantly improved clinical outcomes and PROs. This suggests that improvement in topical therapy for psoriasis need not only to be achieved by the identification of new targets and the development of new APIs, but that improvement in the vehicle used to deliver existing APIs has the potential to result in significant clinical and patient benefits.

Abstract
Skin is the largest organ of the human body and plays the most important role in protecting against pathogen and foreign matter. Three important modes such as topical, regional and transdermal are widely used for delivery of various dosage forms. Among these modes, the topical dosage forms are preferred because it provides local therapeutic activity when applied to the skin or mucous membranes. Additives or pharmaceutical excipients (non-drug component of dosage form) are used as inactive ingredients in dosage form or tools for structuring dosage forms. The main use of topical dosage form additives are controling the extent of absorption, maintaining the viscosity, improving the stability as well as organoleptic property and increasing the bulk of the formulation. The overall goal of this article is to provide the clinician with information related to the topical dosage form additives and their current major applications against various diseases.

Abstract
Background. Lichen sclerosus (LS) is an autoimmune inflammatory skin disease that leads to tissue sclerosis. Actually, the first-line treatment consists of local steroid as clobetasol propionate (CP). Polydeoxyribonucleotide (PDRN) has demonstrated anti-inflammatory effects through the reduction of cytokine production and growth stimulation of fibroblast. Objective. To evaluate the efficacy of intradermal administration of PDRN in male patients suffering from genital lichen sclerosus in addition to topical 0.05% CP, as compared to administering 0.05% CP without PDRN injection. Patients/Methods. A group of male patients (n = 28; aged 25 to 65) suffering from LS were observed during topical therapy or subdermal in addition to topical therapy. Disease activity at baseline was evaluated on Investigator's Global Assessment (IGA) and the Dermatology Life Quality Index (DLQI). We used polydeoxyribonucleotide in a commercial preparation for human use and a topical CP emulsion. Results. After therapy, in all group A patients there has been a regression of most of clinical pathological signs, while there has been a moderate improvement in all group B patients. Conclusions. On site intradermal administration of PDRN, associated with CP 0.05% cream, seemed to be associated with a clinical improvement of lichen sclerosus better than CP used in single therapy.

Abstract
Psoriasis is a lifelong, chronic, and immune-mediated systemic disease, which affects approximately 1-3% of the Caucasian population. The different presentations of psoriasis require different approaches to treatment and appropriate prescriptions according to disease severity. The use of topical therapy remains a key component of the management of almost all psoriasis patients, and while mild disease is commonly treated only with topical agents, the use of topical therapy as adjuvant therapy in moderate-to-severe disease may also be helpful. This paper focuses on the cutaneous mechanisms of action of corticosteroids and on the currently available topical treatments, taking into account adverse effects, bioavailability, new combination treatments, and strategies to improve the safety of corticosteroids. It is established that the treatment choice should be tailored to match the individual patient's needs and his/her expectations, prescribing to each patient the most suitable vehicle.

Abstract
Some cosmetic products manufactured in Korea have been suspected to contain anti-inflammatory corticosteroids, such as clobetasol propionate and betamethasone dipropionate, for the treatment of eczema, seborrhea and psoriasis, without any indication on the label of the cosmetic products. Due to their severe side effects, such as permanent skin atopy, these two corticosteroids in cosmetic products need to be monitored from a forensic point of view. Cosmetic product samples (number of samples=47) of manufacturers charged by consumers have been collected in local and online markets of Korea, and they were validated and analyzed by a simple high performance liquid chromatography (HPLC) method with ultraviolet diode array (UV-DAD). LC-MS/MS and LC-MS were used to confirm these steroids in cosmetic samples with diagnostic ions (m/z) and isotope ratio. Linearity was studied with 0.5-10μg/mL range in both steroids. Good correlation coefficients (r(2)≥0.999) were found, and their limits of quantifications were 0.59μg/mL and 0.66μg/mL in clobetasol propionate and betamethasone dipropionate, respectively. At three different concentrations spanning the linear dynamic ranges, mean recoveries were always higher than 93%, and precisions for intra-day and inter-day analyses were both less than 3.5%. The results show 32-96.4μg/g levels of clobetasol propionate in five different cosmetic products. Also, betamethasone dipropionate in a sample was monitored at the level of 195.1μg/g. This fact reveals that some manufacturers have added these steroids in their cosmetic products to advertise the treatment effect for skin atopy. Thus, these cosmetic products need to be monitored carefully, and ultimately removed from the market.

Abstract
Clobetasol 0.05% spray, a topical clobetasol propionate, is a non-greasy formulation that has shown increased clinical efficacy in a head-to-head comparison with foam formulation. Moreover, available data from randomized, controlled, double-blind trials suggests that clobetasol spray is, in fact, slightly more effective than most, if not all, other preparations of clobetasol. The fact that clobetasol spray is exceptionally easy to comply with may have played a major role in this outcome; however, other factors must be considered. These include vehicle metamorphosis post-application as well as vehicle and excipient effects on stratum corneum permeability. Basic concepts in topical drug delivery and how they apply to this spray vehicle may further explain the greater efficacy of clobetasol spray.

Abstract
IMPORTANCE OF THE FIELD Psoriasis is one of the most common human skin diseases. Topical therapy forms the cornerstone in the management of mild-to-moderate psoriasis. Topical therapies are also used as adjunctive to systemic therapy in moderate and severe forms of the disease. AREAS COVERED IN THIS REVIEW In this review, an overview of psoriasis pathogenesis, new topical medications for psoriasis, new targets and molecules, combination topical therapies and combination of topical and phototherapy is provided. Over the past decade several efficacious and acceptable treatment options have emerged from the age-old therapies. The development of sophisticated formulation options has led to an enhancement in the rate and extent of drug delivery across the skin, increasing therapeutic value and improving patient compliance. WHAT THE READER WILL GAIN Readers will learn about monotherapy and combination topical products as well as new topical drug delivery technology to achieve optimal clinical outcomes. This review will highlight the need to generate more dermal pharmacokinetic data for better understanding of the impact of formulation change on skin pharmacokinetics to help design improved topical drug delivery systems. TAKE HOME MESSAGE New topical formulations have the potential to achieve better efficacy with improved safety profile.
