Definitions

• the invention relates to a medicament containing xenon.
• WO 02/22141 A2 describes the use of xenon or xenon-containing gases as medicaments, in particular cardiovascular agents.
• ischemic pulmonary disease Many pharmacological agents reach the target site (site of action) in a patient's body via the bloodstream. If blood flow to a part of the body is restricted, the active substances cannot reach the site of action in sufficient quantities. Anemia of the blood in individual parts of the organ due to insufficient blood supply is called ischemia. Ischemia arises, for example, from thrombosis or embolism. Serious circulatory disorders in the brain occur in the event of a stroke.
