N-HYDROXY-4-{5-[4-(5-ISOPROPYL-2-METHYL-1,3-THIAZOL-4-YL)PHENOXY]PENTOXY}BENZAMIDINE 2 ETHANSULFONIC ACID SALT, PROCESS FOR THE PREPARATION THEREOF AND PHARMACEUTICAL COMPOSITION COMPRISING THE SAME

摘要

An N- hydroxy-4- benzamidine 2 ethansulfonic acid salt is provided to show excellent solubility, stability, and bioavailability, as well as a higher initial release rate than 2 methansulfonic acid salt thereof. An N-hydroxy-4-benzamidine 2 ethansulfonic acid salt is represented by a formula(1) and is prepared by reacting N- hydroxy-4-benzamidine and ethanesulfonic acid in an inert solvent. A pharmaceutical composition for preventing and treating osteoporosis, bone fractures, allergic or inflammatory diseases comprises the N- hydroxy-4-benzamidine 2 ethansulfonic acid salt and a pharmaceutically acceptable carrier. An oral formulation for preventing and treating osteoporosis, bone fractures, and allergic inflammatory diseases, comprises the N- hydroxy-4-benzamidine 2 ethansulfonic acid salt along with (a) at least one carbonate selected from the group consisting of alkali metal carbonate, alkali metal bicarbonate and alkaline earth metal carbonate; (b) at least one disintegrant selected from the group consisting of sodium carboxymethyl starch, sodium carmellose, calcium carmellose and sodium croscarmellose; or a combination of (a) and (b).
