[Compliance to therapy in daily practice].

Therapeutic possibilities have never been so numerous as nowadays. Although the physician may thus feel more powerful he is still deceived by the behaviour of his patients towards intake of the drugs he prescribes. If the risks of a poor compliance with pharmacotherapy are recognized adequate strategies can be developed in order to prevent this behavioural attitude which leads to therapeutic failure and waste financial resources. The follow-up of every pharmacotherapy should therefore be equally important as a just diagnosis.
