Abstract
PURPOSE:To produce a durative preparation which causes no reduction in bio- availability and no gastrointestinal disorders, by using quick-acting AD-1590 and slow-acting AD-1590 containing ethyl cellulose as a component for making preparation at a specific ratio. CONSTITUTION:Quick-acting AD-1590 [2-(8-methyl-10,11-dihydro-11-oxobenz[b, f]oxepin-2-yl)propionic acid] and slow-acting AD-1590 are mixed so that the weight ratio of AD-1590 in both components becomes 2:8-6:4, preferably 3:7-4:6. The slow-acting AD-1590 is obtained by coating the quick-acting AD-1590 with ethyl cellulose and a water-soluble cellulose such as hydroxypropylcellulose, or preparing a mixture of AD-1590, ethyl cellulose, a water-soluble cellulose and other components with a solvent. Both components are preferably mixed in the same particle size.
