Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing may include a cover layer, an activator layer such as an acid providing layer and nitric oxide source layer, such as a nitrite providing layer. The activator layer may include acidic groups and may be hydrogel, xerogel, or other suitable material. The nitric oxide source layer may include a nitrite salt. Nitrite ions of the nitric oxide source layer may react with the acidic groups of the activating layer to generate nitric oxide. The wound dressing may further include a composite layer, such as a layer with an acquisition distribution layer embedded within an activator gel layer. Additional composite layers may include various absorbent materials embedded within an activator gel layer.

Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing may include a cover layer, a nitric oxide source layer, such as a nitrite providing layer, an absorbent layer such as a foam, and a gel material adhered to the absorbent layer. The gel material may include perforations in a cured pattern structure. The perforations may define a plurality of fluid channels extending through the gel material. The gel material may form an active wound contact layer for use in generating nitric oxide.

Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing may include a cover layer, an activator layer such as an acid providing layer and nitric oxide source layer, such as a nitrite providing layer. The activator layer may include acidic groups and may be hydrogel, xerogel, or other suitable material. The activator layer may include a copolymer of monomers with one or more covalently linked multifunctional groups.

The wound dressing may include a cover layer, an activator layer such as an acid providing layer and nitric oxide source layer, such as a nitrite providing layer. The activator layer may include acidic groups and may be hydrogel, xerogel, or other suitable material. The nitric oxide source layer may include a nitrite salt. Nitrite ions of the nitric oxide source layer may react with the acidic groups of the activating layer to generate nitric oxide. The activating layer may include a window at the center, and a central absorbent material may be positioned at the window. Various separating layers may also be incorporated into the dressing to control the interaction between activating layer and nitric oxide source layer.

Abstract: Disclosed embodiments relate to a wound dressing which can generate nitric oxide. The wound dressing comprises a cover layer, an acid providing layer and a nitrite providing layer. The acid providing layer comprises acidic groups and may be hydrogel or Xerogel. The nitrite providing layer comprises a nitrite salt. The wound dressing may also include other layers, one or more acquisition distribution layers or masking layers. The masking layers can at least partially prevent visualization of the layer below the masking layer. Nitrite ions of the nitrite providing layer may react with the acidic groups of the acid providing layer to generate nitric oxide. The acid providing layer further includes one or more material layers to reduce the adhesiveness of the acid providing layer. The acid providing layer can also include perforations.

Abstract: An antibacterial or anti-acne formulation suitable for topical or local application to human skin containing (a) either usnic acid or an usnate and (b) a metal salt selected from copper salts, bismuth salts, and mixtures thereof, wherein if the component (a) is an usnate, the components (a) and (b) are not the same compound.

Abstract: An alkyl- or halo-substituted benzoquinone, hydroquinone or mixture thereof, for use in the treatment of a periodontal disease, and/or for use in the treatment of a condition which is caused by, transmitted by or exacerbated by P. gingivalis or by biofilm formation by P. gingivalis.

Abstract: Antibacterial formulation containing (a) a dialkyl sulphosuccinate (DAS) or derivative thereof and (b) a carbanilide antibacterial agent such as triclocarban (TCC). The formulation may be for use in the treatment of a bacterial condition, in particular acne, body odour or a condition affecting the oral cavity. It may contain, in addition to the DAS and the carbanilide, (i) a poly-oxyalkylene-based solubilising agent; (ii) an organic solvent; (iii) a thickening agent; and (iv) water.

Abstract: An antimicrobial formulation containing a synergistic combination of a quinone, such as an optionally substituted benzoquinone or hydroquinone, and a bismuth salt. The formulation may in particular be used against propionibacteria, more particularly to treat skin and skin structure conditions such as acne, or against microbial infections within the oral cavity.

Abstract: An antimicrobial formulation containing a quinone, such as a benzoquinone or hydroquinone, and a copper salt. The formulation may in particular be used against staphylococci or propionibacteria, more particularly to treat skin and skin structure conditions such as acne.

Abstract: A benzoquinone or hydroquinone for use in the topical treatment of a condition which is caused, exacerbated or transmitted by bacterial, in particular staphylococcal or propionibacterial, activity. The condition may be a skin or skin structure condition such as acne. The invention also provides the use of a benzo- or hydroquinone in the manufacture of a medicament for the treatment of such a condition.

Abstract: An antimicrobial formulation containing (a) a peroxide selected from the group consisting of diacyl peroxides, alkyl hydroperoxides and metal peroxides and (b) a benzoquinone or hydroquinone. The formulation may in particular be used against staphylococci or propionibacteria, more particularly to treat skin and skin structure conditions such as acne.
