  • Publication number: 20070258939
    Abstract: A pharmaceutical composition for embolisation of blood vessels, especially for benign tumours, comprises a polymeric embolic agent and, associated with the polymer in a releasable form, a local anaesthetic agent. The polymer is preferably in particulate form, such as in the form of microspheres. A suitable polymer is a crosslinked polyvinyl alcohol polymer formed by the copolymerisation of PVA macromer with other ethylenically unsaturated monomers. The composition provides a synergistic treatment for the symptoms of tumours such as uterine fibroids, leading to size regression as well as pain relief.

  • Publication number: 20060135714
    Abstract: An initiator for the terminal group of the polymer product of an atom or gruop radical transfer polymerisation has an activated carboxyl or an amine group which is reacted with an amine or carboxyl (respectively) group containing biologically active compound. The initiator is preferably 4-(3-(2-bromo, 2-methyl-propionate)phenyl)-propionic acid N-hydroxysuccinimide ester or 2-bromo, 2-methyl-propionic acid N-hydroxysuccinimide ester. The monomers preferably comprise a zwitterionic monomer such as 2-methacryloxyethyl-2?-trimethyl ammoniumethyl phosphate inner salt.

  • Publication number: 20060057198
    Abstract: A pharmaceutical composition for uterine fibroid embolisation comprises a polymer and, associated with the polymer in a releasable form, a COX inhibitor, e.g. a non-steroidal anti inflammatory drug, such as ibuprofen. The polymer is preferably in particulate form, such as in the form of microspheres. A suitable polymer is a crosslinked polyvinyl alcohol polymer formed by the copolymerisation of PVA macromer with other ethylenically unsaturated monomers. The composition provides a synergistic treatment for the symptoms of uterine fibroids, leading to size regression as well as pain relief.
