[Open study of L-5-H.T.P. in melancholic depressed patients over 50 years of age (author's transl)]

The authors report a trial on the antidepressive activity of L.5-H.T.P. The clinical population is relatively homogeneous; it consists of melancholic patients, aged over 50. The results are inferior to those obtained with other antidepressant therapies. They do not verify that L.5-H.T.P. has an antidepressive action in elderlies. However, the authors do not put aside that L.5-H.T.P. can be interesting in some varieties of depression.
