An interpolymer complex of a polyacid and a water-soluble, non-ionic polymer, preferably polymethacrylic acid and polyethyleneglycol, which forms a stable, insoluble complex in water at acidic pH, and which is converted to an extrudable liquid upon addition of an appropriate amount of a complex solubilizer, preferably ethanol. The resultant complex is particularly useful as an injectable, sustained release delivery vehicle for bio-affecting substances, including therapeutic agents.
Un complexe interpolymère d'un polyacide et d'un polymère soluble dans l'eau et non-ionique, de préférence l'acide polyméthacrylique et le polyéthylénéglycol forme un complexe stable non-soluble dans l'eau à un pH acide, et est transformé en liquide extrudable par adjonction d'une quantité appropriée d'agent de solubilisation, de préférence de l'éthanol. Le complexe ainsi obtenu est particulièrement utile comme vecteur injectable et à libération prolongée de substances bio-efficaces, et notamment d'agents thérapeutiques.
