ABSTRACT:
A process for the preparation of an orally administrable calcium composition comprising the steps of: (i) obtaining a physiologically tolerable particulate calcium compound having a mean particle size in the range 3 to 40 μm, having a crystalline structure and having a surface area of 0.1 to 1.2 m2/g; (ii) mixing the calcium compound with a water-soluble diluent and an aqueous solution of a water soluble binder in a fluid bed granulation apparatus and drying the resulting mixture to produce a first granulate; (iii) optionally mixing the first granulate with one or more further components to produce a second granulate; and (iv) optionally compressing the first or second granulate to form tablets.
