Background: Stress is a risk factor for depression and anxiety disorders, disrupting neuronal processes leading to exaggerated fear and compromised coping behaviors. Current antidepressants are only partially effective. Vortioxetine, a novel multimodal antidepressant, is a serotonin transporter inhibitor; 5-HT 3, 5-HT 7, and 5-HT 1D receptor antagonist; 5-HT 1B partial agonist; and 5-HT 1A agonist. Fabfilter Saturn Serial here. We have shown that chronic dietary vortioxetine administration reversed stress-induced deficits in cognitive flexibility. In the present studies, we investigated the generality of vortioxetine’s effects on other stress-related behavioral changes after different types of chronic stress. Methods: In experiment 1, rats were fear-conditioned by pairing a tone with footshock, then exposed to chronic plus acute prolonged stress. In experiment 2, rats were exposed to chronic unpredictable stress.

In both experiments, beginning on day 4 of chronic stress, vortioxetine was given in the diet (24 mg/kg/d). In experiment 1, effects of vortioxetine were tested on stress-induced changes in retention and extinction of cue-conditioned fear, and in experiment 2, on coping behavior on the shock probe defensive burying test after chronic stress. Significance Statement Vortioxetine is a novel multimodal antidepressant. We have shown previously that vortioxetine improves stress-induced deficits in cognitive function mediated in the prefrontal cortex of rats that model cognitive components of depression and anxiety disorders in humans. In the present study, we expand the generality of these observations. The results show that chronic vortioxetine administration also reduces the exaggerated expression of fear memory and the shift from active to maladaptive passive coping behavior induced by 2 different chronic stress treatments. This provides further evidence of the therapeutic potential of vortioxetine in the management of depression and anxiety disorders.

Introduction Chronic stress is a major risk factor for the development of depression and anxiety disorders (;;; ). In preclinical studies, we have shown different types of chronic stress to induce anxiety-like behaviors and deficits in cognition, executive function, and maladaptive coping behaviors that resemble symptoms of anxiety, cognitive disturbance, and avoidance behaviors that are prevalent in stress-related psychiatric disorders (;; ).

Such symptoms can be particularly resistant to treatment (). Current pharmacological approaches for the treatment of depression, including serotonin-specific reuptake inhibitors (SSRIs), are only partially effective, with an unacceptably high incidence of residual symptoms, relapse, and treatment resistance (; ). SSRIs are also used for treatment of a spectrum of anxiety disorders, including panic disorder, posttraumatic stress disorder (PTSD), generalized anxiety disorder, and obsessive-compulsive disorder and others (see ), with varying degrees of efficacy. Vortioxetine is a novel antidepressant with multimodal action approved by the Food and Drug Administration for the treatment of major depressive disorder ().
