Abstract
A composition for chemoembolotherapy of solid tumours comprises particles of a water-insoluble water-swellable synthetic anionic polymer and, absorbed therein an anthracycline. Suitably the polymer is a poly(vinyl alcohol) based polymer and the drug is doxorubicin.
Claims33
A composition comprising particles having a matrix of water-swellable water-insoluble polymer and, absorbed in the matrix, a water-soluble therapeutic agent, and is characterised in that the polymer has an overall anionic charge at a pH in the range 6 to 8, in that the particles, when swollen to equilibrium in water have particle sizes in the range 40-1500 μm and in that the therapeutic agent is an anthracycline compound having at least one amine group
A method of embolotherapy of a patient having a solid tumour, in which anthracycline is delivered from a polymer matrix formed by the copolymerisation of a poly(vinyl alcohol) macromer having at least 2 pendant ethylenically unsaturated groups per molecule and an ethylenically unsaturated anionic monomer.
