Fecha de publicación: | 15-abr-2005 | Editor: | Elsevier | Citación: | Drug Discovery Today 10 (8) : 578-585 (2005) | Resumen: | Existing antidepressant treatments exhibit limited efficacy and a slow onset of action. Several neurobiological adaptive mechanisms might delay the clinical effects of antidepressants, whose therapeutic action is primarily triggered by an increase of serotonergic and noradrenergic neurotransmission. Here, we review several potential mechanisms that could be useful to increase the speed of current antidepressant drugs, such as additional blockade of aminergic autoreceptors or antagonism of certain postsynaptic (5-HT2A, 5-HT2C) receptors. The potential use of strategies not based on monoaminergic transmission, such as CRF and NK1 receptor antagonists, or more novel strategies, based on glutamatergic or GABAergic transmission or on intracellular messengers, are also reviewed. The global impact of depression is growing but there have been no substantial advances to overcome two main problems of its treatment: slowness and limited efficacy. This review focuses on potential neurobiological mechanisms to produce rapidly acting antidepressants. | Versión del editor: | http://dx.doi.org/10.1016/S1359-6446(05)03398-2 | URI: | http://hdl.handle.net/10261/34590 | DOI: | 10.1016/S1359-6446(05)03398-2 | ISSN: | 1359-6446 | E-ISSN: | 1878-5832 |
