Abstract: The present invention relates to a sterile gel formulation suitable for use in filling a wound cavity and delivering an active ingredient thereto, the gel further having a pH range of 4.5 to 8.5, low bioadhesive strength and cohesive integrity and being formed from a polymer selected from among the group consisting of poly(vinyl) alcohol (PVA) polymer and a PVA-polyvinyl acetate copolymer, a cross-linker being a salt form of boron that produces borate ions in aqueous solution, at least one compound which has a beneficial effect as an active ingredient in the wound and at least one modulator, the modulator being a low molecular weight species that is capable of binding borate or PVA in aqueous solution through a mono-diol or di-diol formation and reduces the pH of PVA-borate hydrogels; wherein the gel is heat and/or gamma sterilised and contains less than 5% acetic acid and the polymer has a degree of hydrolysis of between 98% and 100% and a molecular weight of from 100,000 to 300,000 Daltons.

Abstract: A gel formulation for use in filling a wound cavity and delivering active ingredient thereto, having a pH range of 6.5 to 7.5, low bioadhesive strength and cohesive integrity and being a PVA borate gel including an active ingredient and a modulator to bind borate and/or PVA in aqueous solution through a mono-diol or di-diol formation and reduces the pH of PVA-borate hydrogels. A suitable modulator is a sugar alcohol such as mannitol and the active ingredient, a medicament suitable for topical application such as a local anaesthetic and/or an antibiotic.
