SUSTAINED-RELEASE PREPARATION ENCLOSED IN EXPANDABLE TUBE

摘要

It is intended to provide a sustained-release preparation from which a volatile drug can be evenly released over a long period of time even in the case where a liquid drug is decreased in a tubular container of the sustained-release preparation. It is intended to provide a container for a sustained-release preparation which is a tubular container composed of two layers including an outer layer and an inner layer, in which the thickness of the inner layer is from 0.12 to 1.2 mm and which has an expandable structure allowing the aspiration of a liquid drug to a height of 25 mm or more due to the capillary action. It is also intended to provide a container unit for a sustained-release preparation provided with a plural number of the containers for a sustained-release preparation as described above.
