Abstract
Nine patients with endogenous depression have been treated with infusions of the synthetic methionine enkephaline analogue FK 33-824 for two days. Only on the first day acute effects on depressive symptoms could be observed. It cannot be decided if the observed mood alterations on the first treatment day are placebo effects. Depressive patients showed fewer adverse reactions than healthy volunteers. This might be explained by the previously described greater pain tolerance in depressives.
