Abstract: The present disclosure relates to a semi-solid topical drug delivery formulation including a silicone-based excipient, at least one volatile solvent, at least one active configured to be topically delivered through a patient's skin for an intended therapeutic application, and at least one enhancer. The formulation may additionally optionally include at least one agent that provides occlusivity when the formulation is applied onto a patient's skin. The at least one active may be a healthcare and/or pharmaceutical active.

Abstract: Dual drug paste compositions are disclosed containing a silicone organic elastomer gel, a hydrophobic drug, and a hydrophilic drug. The dual drug paste compositions are useful for the simultaneous delivery of a hydrophobic and hydrophilic drug to a substrate without the drawbacks of using traditional gels, solutions or emulsions.

Abstract: A controlled-release composition for topical application to a substrate includes an oil-in-water emulsion and an active agent incorporated into the oil-in-water emulsion. The oil-in-water emulsion is substantially free of lipophilic solvent and is formed by mechanical inversion of a water-in-oil emulsion. The water-in-oil emulsion includes a silicone component, a surfactant, and water. A method of delivering the active agent to the substrate provides the oil-in-water emulsion and incorporates the active agent into the oil-in-water emulsion for delivery of the active agent to the substrate upon application of the oil-in-water emulsion to the substrate.

Abstract: This invention relates to a method of enhancing the adhesion of a silicone containing adhesive formulation. The method comprises mixing 1 to 99.9 wt. % of a silicone-containing adhesive formulation and 0.1 to 50 wt. % antiperspirant compound to form a composition. The composition is then applied onto a surface and allowed to cure. The invention also relates to a composition comprising 1 to 99.9 wt. % of a silicone-containing adhesive formulation and 0.1 to 50 wt. % antiperspirant salt. The resultant adhesive films are especially useful in healthcare and cosmetic applications where they inhibit perspiration and, thus, retain the adhesive strength of the adhesive.

Abstract: A hydrophobic matrix is prepared by forming a semi-solid composition containing a solid powdered hydrophilic drug and/or a solid powdered hydrophilic excipient, and a silicone polyether, and then adding the semi-solid composition to a silicone pressure sensitive adhesive or a solution containing a solvent and a silicone pressure sensitive adhesive, and mixing the composition and the silicone pressure sensitive adhesive or the solution containing the solvent and the silicone pressure sensitive adhesive together to form the hydrophobic matrix. The hydrophobic matrix can be applied to a substrate, typically the human skin by means of a transdermal patch for continuous and controlled transdermal administration of drugs.

Abstract: A method for increasing the adherence of a silicone gel to a substrate using a primer material. The method is particularly useful for adhering a medical prosthesis to a human or animal body.

Abstract: A multi-layer dressing and controlled-release composition for topical application to a substrate include an emulsion and an active agent incorporated into the emulsion. The active agent includes a protein. A method of delivering the active agent to the substrate provides the emulsion and incorporates the active agent into the emulsion for delivery of the active agent to the substrate. Multi-layer dressings and methods particularly suited for management of wound exudate and effective debridement of wound eschar.
