    Abstract:
    Depression has been associated with a disturbance in serotonin function as reflected in platelet uptake of the transmitter as well as in CSF levels of its major metabolite, 5-hydroxyindoleacetic acid (5-HIAA). CSF 5-HIAA levels are subnormal in approximately 30% of melancholia patients. Early studies suggested that patients with a disturbed serotonin metabolism were less responsive to treatment with uptake inhibitors with a preferential action on noradrenaline neurons. Such findings encouraged the search for compounds with a selective effect on serotonin neurons. Although some classical antidepressants are potent inhibitors of serotonin uptake, they are not selective, since their metabolites, which appear to have antidepressant effects, inhibit noradrenaline uptake. The consistent findings of an increased risk for suicide in patients with low CSF 5-HIAA underlines the importance of exploring drugs that act on serotonin transmission. The biochemical effects of some serotonin uptake inhibitors and their clinical and research potential in depression are reviewed.
