Abstract
Abstract Disclosed herein is an oral mobenzoxamine preparation which comprises a clathrate compound of mobenzoxamine or a salt thereof and cyclodextrin. Since the clathrate compound remains extremely stable even when stored for a long period of time and its absorption through the digestive tract is good upon its oral administration, the clathrate compound can be used advantageously as an orally-dosable preparation.
