Patent ID: 8778377

Claim:
An injectable ceramic paste for drug delivery in a subject, comprising: i) a ceramic precursor powder comprising a hydraulic non-hydrated calcium aluminate and/or calcium silicate phase (CBC phase), having a particle size of below 5 μm, a resorbable or stable phase comprising porous hydrated chemically bonded ceramics and/or oxides, having a granule size of 500 μm, open porosity in a range of 10-40 vol %, and an average pore size of 0.01-5 μm, and optional additives; ii) an effective amount of a pharmaceutical agent for drug delivery; and iii) a water-based hydration liquid, in a water to ceramic precursor powder ratio of 0.20-0.50, said paste forming an injectable paste capable of being injected into the subject, and forming a chemically bonded ceramic drug carrier material comprising the pharmaceutical agent upon hydration of the hydraulic phase after being injected into the subject.
