Antidepresivos de acción rápida : presente y futuro

Abstract

[ES]: El trastorno de depresión mayor constituye una patología muy prevalente a nivel global con un gran impacto económico y social. A pesar de ello ni su fisiopatología ha sido del todo dilucidada ya que existen diversos neurotransmisores, así como complejos circuitos cerebrales implicados, ni se han desarrollado fármacos novedosos en las últimas décadas. Actualmente, el arsenal terapéutico del que disponemos se basa fundamentalmente en los fármacos monoaminérgicos. Esto resulta efectivo en muchos pacientes, sin embargo, estos fármacos presentan dos desventajas cruciales: un lento inicio de acción y una limitada eficacia. Existe un número no despreciable de pacientes en los que dicho tratamiento fracasa y, por tanto, presentan una respuesta parcial al tratamiento y/o un índice alto de recaída, lo que repercute en su calidad de vida e incrementa el riesgo de suicidio. Para tratar de solventar este problema se han venido proponiendo nuevas estrategias terapéuticas con resultados muy prometedores, a destacar: pequeñas dosis del receptor antagonista NMDA: quetamina, esta sustancia genera una respuesta antidepresiva rápida y duradera en pacientes con depresión resistente al tratamiento convencional; la estimulación cerebral profunda del córtex cingular anterior (Cg25). Asimismo, nuevas estrategias moleculares aún en estadio preliminar que modulan la expresión de ciertos genes, como el RNA de interferencia están demostrando un potencial futuro en el terreno del tratamiento antidepresivo. Se requerirán más estudios para desengranar los entresijos responsables de la etiopatogenia del trastorno depresivo y así diseñar fármacos dirigidos a dianas específicas.

[EN]: Major depression disorder is a prevalent disorder worldwide with very high economic and social impact. Nevertheless, its pathophysiology is poorly known considering that there are several neurotransmitters and brain areas implicated. In addition, there have not been innovative drugs in the last decades. Selective serotonin reuptake inhibitors and serotonin and norepinephrine reuptake inhibitors are most used antidepressant treatments.They are effective in many patients but these drugs show slow onset of action and limited efficacy. Some patients do not achieve a good result and they show recurrent or chronic depression resulting in a poor quality of life and increase suicide risk. To solve this, new strategies have been used with promising results. Hence, single doses of the non-competitive NMDA receptor antagonist ketamine; as well as deep brain stimulation of ventral anterior cingulate cortex (Cg25) evoke rapid and long-lasting antidepressant responses in treatment-resistant patients. Likewise, RNA interference (RNAi) strategies aimed at modulating the expression of certain genes have been preliminarily used to evoke antidepressant-like responses in animals. More studies are essential to elucidate the pathophisiology of depression in order to design drugs with specific targets.
