  • Publication number: 20090266420
    Abstract: A system and a method for making an injectable mixture using at least one first pulverulent component and a second liquid component with a first piston/cylinder arrangement with a cylinder with an axial extension and a piston, wherein the cylinder includes a measured amount of the pulverulent component, a separate reservoir including a corresponding measured amount of the liquid component, and a transfer device for sealed transfer of said amount of the liquid component to the cylinder for subsequent mixing and injection of the completed mixture. The first piston/cylinder arrangement is an injection syringe. A mixing element being manoeuvrable by a user is positioned inside the cylinder. At least one gas transferring channel means leading to the cylinder is arranged at the cylinder. Engagement means are arranged for connecting the first injection syringe to the separate reservoir during transfer of the liquid component.

  • Publication number: 20090118215
    Abstract: A novel method for the preparation of a highly densified and at least partly, preferably fully or almost fully hydrated ceramic for use in the preparation of a pharmaceutical composition notably for controlled-release of one or more therapeutically, prophylactically and/or diagnostically active substance. The method involves a concomitant step of hydrating and densifying a bioresorbable and hydratable ceramic such as calcium sulphate. The invention also relates to compositions comprising such a highly densified ceramic. The pharmaceutical composition is useful for targeted and controlled local prolonged release of active substances, e.g. anti-cancer agents, whereby the spectrum and severity of side effects are minimized due to an optimized local concentration-time profile.

  • Publication number: 20090036392
    Abstract: The present invention relates to a drug carrier composition comprising i) one or more biodegradable hydrating ceramics ii) one or more expandable agents, and iii) sorbed aqueous medium which in solid form has a ruptured structure. The function of the expandable agent is to create a ruptured structure in the solidified composition, either a foam-like structure or a disintegrated structure where it is split into a large number of parts, particles, units, granules or pieces, so as to obtain an enlarged apparent surface area that is exposed to degradation or erosion upon administration. Suitable substances to obtain this surface enlarging effect are gas-forming agents or swelling agents, gelling agents or disintegrants, here referred to as expandable agents. The expandable agents may be bioresorbable or non-bioresorbable.

  • Publication number: 20030220414
    Abstract: Biocompatible cement compositions in a hardened state for filling an orthopaedic cavity and fixating a medical implant in the skeletal bone, by mixing fixation grains (granules) with a biocement slurry or paste, either inside or outside an orthopaedic cavity. A medical implant can be inserted into the grains either before or after the addition of the biocement slurry or paste. The biocompatible cement compositions achieve both high initial fixation strength, as well as a fixation providing long-term stability and biocompatibility, without any negative health effects. The biocompatible cement compositions can suitably be used for filling orthopaedic cavities due to for example osteoporosis, cancer, fractures or other types of bone defects, and can also be used for fixating general orthopaedic and dental implants.
