Abstract: Microvascular dysfunction remains a major contributor to the development of skin complications. The inventors assessed the impact of the local inhibition of soluble epoxide hydrolase (sEH), which metabolizes vasodilator and anti-inflammatory epoxyeicosanoids, on the diabetic skin microvascular dysfunction. The inventors have therefore developed some formulations of sEH inhibitors (GSK2256294 and t-AUCB) for topical administration. In particular, they show that an aqueous gel containing 400 mg/L t-AUCB dissolved in 50% dimethy lsulfo xide (DMSO) allowed a stable and continuous diffusion of t-AUCB from 2 hours after application on skin pig ears to over a period of 24 h. Compared to a control gel, the gel with t-AUCB did not significantly modify the basal skin blood flow but improved the altered hyperemic response of db/db mice 2 hours after application.

Abstract: A device treats a region of the body of a patient having a cutaneous ulcer, including: a hydrogel, hydrocolloid, hydrocellular or hydrofiber primary dressing, impregnated with treprostinil, that can be shaped to the contours of the region to be treated, a so-called “active” electrode in contact with the primary dressing, a so-called “passive” electrode at a distance from the active electrode, a DC generator, the terminals of which are connected to the electrodes, the cathode and the anode respectively forming the active electrode and the passive electrode for iontophoresis, so as to cause treprostinil to migrate by cathodal iontophoresis into the region to be treated.
