Abstract: The present invention relates to an implantable paste comprising bioactive glass powder having a size distribution of 0.5-45 ?m, bioactive glass granules having a size distribution between 100 and 4000 ?m, low molecular weight polyethylene glycol having a molecular weight range of 200-700 g/mol, medium molecular weight polyethylene glycol having a molecular weight range of 700-2500 g/mol, high molecular weight polyethylene glycol having a molecular weight range of 2500-8000 g/mol and glycerol. The composition of the bioactive glass is 45-55 weight-% of SiO2, 20-25 weight-% of Na2O, 18-25 weight-% of CaO and 3-6 weight-% of P2O5, and the molecular weight of the low molecular weight polyethylene glycol and of the medium molecular weight polyethylene glycol differ from each other by at least 80 g/mol and that the molecular weight of the medium molecular weight polyethylene glycol and of the high molecular weight polyethylene glycol differ from each other by at least 300 g/mol.

Abstract: The present invention relates to a bioactive glass having the composition of SiO2 44-65 wt-% of the final total weight, Na2O 5-26 wt-% of the final total weight, CaO 10-25 wt-% of the final total weight, K2O 0-1 5 wt-% of the final total weight, MgO 0-6 wt-% of the final total weight, B2O3 0-4 wt-% of the final total weight, and P2O5 0-7 wt-% of the final total weight, for use in the long- and short-term prevention and/or treatment of conditions relating to or caused by bone infections, provided that the total amount of Na2O and K2O is 10-30 wt-% of the final total weight, and that any source of oxygen capable of releasing oxygen in the form of molecular oxygen or reactive oxygen species, is absent.
