[The importance of age dependent changes of the organism for therapy (author's transl)]

Molecular and supramolecular mechanisms of ageing involve biochemical, physiological and morphological alterations of organs. Furthermore physiological disturbances are superimposed by pathological mechanisms of ageing. As a result the number of diseases in higher age increases as well as there are a lot of therapeutical problems. The following paper tries to reveal that physiological and pathological changes of different organs (heart, kidney, lung, brain) influence the therapy of older man. The results demonstrate that it is necessary to stimulate the research of pharmacodynamics and kinetics in the higher age.
