Topical and/or transdermal bioactive compound delivery system The present invention provides a topical and/or transdermal bioactive compound delivery system comprising a non-aqueous matrix, the matrix comprising a water-sensitive bioactive compound. In particular, the matrix comprises a three-dimensional polymeric network comprising at least a co-polymer, at least a cross-linking agent, and at least a non-aqueous and/or non-volatile solvent and wherein the water-sensitive bioactive compound is housed by the three-dimensional network. Even more in particular, the matrix comprises a co-polymer of N-vinylacetamide and sodium acrylate aluminium chloride; N-methyl-2-pyrrolidone; propylene glycol; glycerine; and at least a water-sensitive bioactive compound.
A topical and/or transdermal bioactive compound delivery system comprising a non-aqueous matrix, the matrix comprising a water-sensitive bioactive compound.
A bioadhesive topical and/or transdermal bioactive compound delivery system comprising a non-aqueous matrix, wherein the matrix is prepared by mixing:
A method of preparing a topical and/or transdermal bioactive compound delivery system comprising preparing a polymeric non-aqueous matrix, the matrix comprising a water-sensitive bioactive compound.
A method of topical and/or transdermal administration of a water-sensitive bioactive material, comprising preparing a polymeric non-aqueous matrix, the matrix comprising a water-sensitive bioactive compound, and applying the matrix on the skin of a mammal in need of treatment.
