  • Salts of active ingredients with polymeric counterions
    Patent number: 10610487
    Abstract: Water-soluble polymeric salts of medicaments sparingly soluble in water consisting of a cationogenic medicament which, in uncharged form or as hydrochloride, has a solubility of less than 0.1% (m/m) in water, artificial intestinal juice or gastric juice, and an anionogenic water-soluble polymer having a solubility in water of at least 5% (m/m) in the pH range of 1 to 13 and which is obtained by free-radically initiated polymerization of a monomer mixture of i) 70 to 90% by weight N-vinylpyrrolidone and ii) 10 to 30% by weight acrylic acid, wherein the sum total of i) and ii) corresponds to 100% by weight.

  • USE OF WATER-SOLUBLE POLYMERS BASED ON N-VINYLPYRROLIDONE AND ACRYLIC ACID AS PHARMACEUTICAL ADJUVANTS
    Publication number: 20180228730
    Abstract: Use of a water-soluble polymer having a solubility in water of greater than 5% (m/m) in the pH range of 1 to 13 and which is obtained by free-radically initiated polymerization of a monomer mixture of i) 70 to 90% by weight N-vinylpyrrolidone and ii) 10 to 30% by weight acrylic acid, wherein the sum total of i) and ii) corresponds to 100% by weight, for the formulation of basic active ingredients sparingly soluble in water, wherein the active ingredients in uncharged form or as hydrochloride have a solubility of less than 0.1% (m/m) in water, artificial intestinal juice or gastric juice.

  • SONOSENSITIVE NANOPARTICLES
    Publication number: 20130281916
    Abstract: A method of delivering a therapeutic substance to tissue comprises delivering the therapeutic substance and nanoparticles to the tissue, the nanoparticles having a diameter in the range from 10 to 1000 nm and surface features having a depth in the range from 5 to 50 nm, and insonating the tissue with pressure waves. Corresponding particles, and associated methods of controlling and imaging the treatment and delivery are also disclosed.
