Abstract
OBJECTIVE Systemic Sclerosis (SSc) is a rare, chronic disease characterized by fibrosis, vascular alterations and digital ulcerations. Few drugs have shown efficacy to enhance wound healing of existing SSc-related ulcers. Local delivery of treprostinil, a prostacyclin analogue, may improve wound healing. The present work aimed first at developing a mouse model of SSc-related ulcerations and second at assessing the effect of iontophoresis of treprostinil on wound healing. METHODS We used two murine models of SSc: chemically-induced with HOCl, and Urokinase-type plasminogen activator receptor (uPAR)-deficient. Excisional wounding was performed on the dorsal midline with a biopsy punch. Animals were randomized into three groups: treated with electrostimulation alone, with treprostinil iontophoresis, or untreated. We assessed wound healing over time, as well as skin microvascular reactivity, inflammation, microvessel density, and collagen distribution, before wounding and after re-epithelialization. RESULTS uPAR-/- mice, but not HOCl-treated mice, showed impaired wound healing and decreased microvascular reactivity compared with their controls. Treprostinil iontophoresis improved wound healing and microvascular density and decreased inflammation in uPAR-/- mice, while electro-stimulation did not. However, treprostinil had no effect on microvascular reactivity and collagen distribution. CONCLUSION This study suggests that excisional wounds in uPAR-/- mice are a relevant model of SSc-related ulcers. In addition, treprostinil iontophoresis enhances wound healing in this model. Further work in now needed to show whether this effect translates in humans.

Abstract
Pay-load deliveries across the skin barrier to the systemic circulation have been one of the most challenging delivery options. Necessitated requirements of the skin and facilitated skin layer cross-over delivery attempts have resulted in development of different non-invasive, non-oral methods, devices and systems which have been standardized, concurrently used and are in continuous upgrade and improvements. Iontophoresis, electroporation, sonophoresis, magnetophoresis, dermal patches, nanocarriers, needled and needle-less shots, and injectors are among some of the methods of transdermal delivery. The current review covers the current state of the art, merits and shortcomings of the systems, devices and transdermal delivery patches, including drugs' and other payloads' passage facilitation techniques, permeation and absorption feasibility studies, as well as physicochemical properties affecting the delivery through different transdermal modes along with examples of drugs, vaccines, genes and other payloads.

Abstract
Microneedle arrays (MNA) are considered as one of the most promising resources to achieve systemic effects by transdermal delivery of drugs. They are designed as a minimally invasive, painless system which can bypass the stratum corneum, overcoming the potential drawbacks of subcutaneous injections and other transdermal delivery systems such as chemical enhancers, nano and microparticles, or physical treatments. As a trendy field in pharmaceutical and biomedical research, its applications are constantly evolving, even though they are based on very well-established techniques. The number of molecules administered by MNA are also increasing, with insulin and vaccines administration being the most investigated. Furthermore, MNA are being used to deliver cells and applied in other organs and tissues like the eyes and buccal mucosae. This review intends to offer a general overview of the current state of MNA research, focusing on the strategies, applications, and types of molecules delivered recently by these systems. In addition, some information about the materials and manufacturing processes is presented and safety data is discussed.

Abstract
Digital skin ulcers are a severe complication of systemic sclerosis. The first-line treatment is intravenous iloprost, but it induces dose-limiting adverse effects. Local administration of treprostinil through skin iontophoresis may be a safe alternative. We conducted a 2-stage, randomized, placebo-controlled single-ascending-dose study in healthy volunteers and patients with systemic sclerosis-related digital ulcer. We further explored the effect of the procedure on skin blood flux. In a first group of healthy subjects, treprostinil and placebo iontophoresis were performed at 3 locations (ie, 6 skin sites): the sole of the foot, the leg, and the fingers. We used a 1-mg/mL hydrogel of treprostinil. We then randomly treated systemic sclerosis-related digital ulcers in a 3:1 ratio of treprostinil or placebo. We used concentrations from 0.1 to 1 mg/mL. All adverse events were recorded and rated according to the Common Terminology Criteria for Adverse Events (CTCAE), whereas skin microvascular blood flux was recorded with laser speckle contrast imaging. Among the 12 healthy volunteers, we observed 60 local adverse effects: burns, skin pain, erythema, and pruritus, graded 1 or 2 on the 5-point CTCAE scale. Treprostinil iontophoresis significantly increased skin blood flux on the leg (AUC0-4 h at 88 460% ± 6436% versus 12 730% ± 3397% baseline flux.min respectively; P < .001) and on the sole of the foot (AUC0-3 h at 20 124% ± 6119% versus 3142% ± 3036% baseline flux.min, respectively; P = .018) with a trend on the finger. Among 5 patients with systemic sclerosis-related digital ulcer, 2 resolutive local adverse effects were reported. Iontophoresis of treprostinil hydrogel was safe in systemic sclerosis patients with digital ulcer.

Abstract
BACKGROUND Lidocaine Hydrochloride (HCL) is one of the commonest topical local anesthetic drugs. The permeation of the lidocaine can be enhanced by iontophoresis (IOP). The purpose of this study was to evaluate the permeability of 2.5 and 5% lidocaine permeation in ex vivo human skin using different IOP waveform. METHODS Continuous and modulated IOP at the current density of 0.5 mA/cm2 were applied across human skin (n = 3) in donor chamber of vertical diffusion cell at 2.5 and 5% lidocaine concentration. High Performance Liquid Chromatography was used to determine lidocaine concentration. RESULTS Findings revealed that lidocaine concentration increased effectively in a time-dependent manner in both modulated and continuous IOP at 2.5 and 5% lidocaine concentration. Compared to the passive group, the flux of lidocaine with modulated and continuous IOP were higher of about six and ten-fold, respectively. However, no significant difference was observed between continuous and modulated IOP groups at both lidocaine concentrations. At 2.5% lidocaine concentration, the permeation time taken by modulated and continuous IOP to attain therapeutic levels of 142 and 164 μg/cm2 , respectively, was approximately 10 minutes. At 5% lidocaine, the therapeutic permeation of 129 and 147 μg/cm2 , respectively, was achieved at approximately 5 minutes after applying iontophoresis waveform. CONCLUSION Study shows that modulated IOP can be a promising alternative method in clinical settings aside from continuous IOP. Based on the clinical requirements, IOP can be used at 2.5 and 5% lidocaine concentration depending on need of relatively short or very short onset action.

Abstract
INTRODUCTION Severe Raynaud's syndrome and DUs are the most prevalent manifestations of SSc peripheral microvascular disease. We tested whether treprostinil iontophoresis on the finger pad of patients with SSc would improve digital blood flow during hand cooling. METHODS Eleven patients with limited cutaneous SSc underwent a double-blinded iontophoresis of treprostinil (2.56 × 10(-4) M during two hours) and placebo (NaCl 0.9%) on two finger pads. Then, the hand was inserted for 30 minutes in a fenestrated cooling box at 8 °C, and skin blood flow was recorded continuously using LSCI. RESULTS During the local cooling, CVC was significantly higher at the treprostinil site than at the placebo site and remained higher 30 minutes after the test. CONCLUSIONS In patients with SSc, digital treprostinil iontophoresis shifts skin blood flow upward during local cooling of the hand and during the initial rewarming phase. Digital treprostinil iontophoresis should now be tested in larger scale studies.
