DUAL MICROCAPSULES

摘要

The outer membrane (10) encapsulates a liquid (12) having one or more smaller microcapsules (mini-microcapsules) suspended therein. The mini-microcapsules contain a complex or a reaction product of a drug which diffuses into the liquid (12) in which mini-microcapsules are suspended. The suspending liquid (12) contains an enzyme which reacts with drug complex or reaction product to regenerate or release the drug. The drug diffuses through the outer membrane (10) into a host.
