Inclusion complex of S-omeprazole (ES omeprazole) using cyclodextrin

摘要

An inclusion complex having anti-ulcer activity comprises a substantially pure optical isomer of a benzimidazole compound and cyclodextrin. The complex preferably comprises S-omeprazole and b -cyclodextrin and is made by adding the cyclodextrin to an aqueous solution of the active material, and then isolating the complex from the solution.
