Effect of co-administration of memantine and sertraline on the antidepressant-like activity and brain-derived neurotrophic factor (BDNF) levels in the rat brain.
A developing body of data has drawn attention to the N-methyl-d-aspartate (NMDA) receptor antagonists as potential drugs for the treatment of major depressive disorder (MDD). We investigated the possibility of synergistic interactions between the antidepressant sertraline with the uncompetitive NMDA receptor antagonist, memantine. The present study was aimed to evaluate behavioural and molecular effects of the chronic treatment with memantine and sertraline alone or in combination in rats. ⋯ Our results indicate that co-administration of antidepressant memantine with sertraline may induce a more pronounced antidepressant activity than treatment with each antidepressant alone. Antidepressant properties using the combination of memantine and sertraline could be attributed to increased levels of BDNF. This finding may be of particular importance in the case of drug-resistant patients and could suggest a method of obtaining significant antidepressant actions whereas limiting side effects.
