PCT No. PCT/FI94/00509 Sec. 371 Date Aug. 6, 1996 Sec. 102(e) Date Aug. 6, 1996 PCT Filed Nov. 11, 1994 PCT Pub. No. WO95/13054 PCT Pub. Date May 18, 1995The object of the invention is a process for preparing a clodronate preparation. The process is characterized in that clodronate is crystallized as disodium clodronate tetrahydrate from an aqueous solution of disodium clodronate; the resulting disodium clodronate tetrahydrate is dry granulated by compressing in such a way that the crystal structure of the disodium clodronate tetrahydrate is preserved and by crumbling and screening the mass to granules of a sutiable size, the dry granulated disodium clodronate tetrahydrate is optionally mixed with suitable excipients, such as filling agents and gliding agents and, if necessary, disintegrants. |
