[Influence of psychologic-social factors on the success of psychopharmacotherapy--effect of treatment milieu].

Interactions between psychopharmacological drugs and milieu factors are reported in the clinical and experimental literature as well. This seems not to be a very striking discovery since both, milieu and psychopharmaca do in fact influence human behaviour. However, little is known about the underlying mechanisms on which this kind of interellations can be based. So some of the hypothetical pathways to be considered are briefly discussed.
