摘要: A pharmaceutical composition for embolization 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 copolymerization of PVA macromer with other ethylenically unsaturated monomers. The composition provides a synergistic treatment for the symptoms of tumours such as uterine fibrioids, leading to size regression as well as pain relief.

摘要: An aqueous composition comprises an amphiphilic block copolymer, having a hydrophilic block comprising pendant zwitterionic groups and a hydrophobic block, and a biologically active compound associated with the polymer. The polymer is preferably in the form of micelles, and preferably the biological active is a hydrophobic drug. The hydrophilic block is preferably formed from acrylic monomer including phosphorylcholine groups. The hydrophobic group is suitably formed from monomer which has groups which can be ionised at useful pH's, especially tertiary amine groups. Micelles may be formed by dissolving the block copolymer in aqueous solvent at a pH at which the amine groups are protonated then raising the pH to a value at which the amine groups are substantially deprotonated, whereupon micelles spontaneously form. The preformed micelles are then contacted with active, under conditions such that solubilisation of the active occurs. The active may be for tumour treatment.

摘要: The present invention relates to conjugates of biologically active compounds, preferably therapeutically active compounds, with polymeric moieties having low polydispersity, as well as controlled polymerisation processes for producing the conjugates. An initiation for a controlled radical polymerisation process comprises a biologically active, usually therapeutically active, moiety and the monomer includes zwitterionic monomer for instance 2-methacryloyloxyethyl-2′-trimethylammonium ethyl phosphate inner salt. The process allows close control of the molecular weight and polydispersity of the polymeric moiety and the possibility of optimising the delivery characteristics of the active agent.

摘要: A process is described for loading hydrophilic polymer particles with a water-insoluble solvent-soluble drug. The particles are preferably embolic agents. The method provides particles having little or no drug at the surface and in a surface layer, whereby the burst effect is minimised. The drug is precipitated in the core of the particle, leading to extended release. The drug is, for instance, paclitaxel, rapamycin, dexamethasone or ibuprofen.
