Compounds with combined norepinephrine reuptake inhibitor (NRI) and serotonin 1A (5-HT(1A)) partial agonist pharmacology may offer a new therapeutic approach for treating symptoms of neuropsychiatric disorders including ADHD, depression, and anxiety. Herein we describe the design and optimization of novel chemical matter that exhibits favorable dual NRI and 5-HT(1A) partial agonist activity. Lead compounds in this series were found to be devoid of activity at the dopamine transporter and were shown to be brain penetrant with high receptor occupancy.

Vortioxetine, which functions as a 5-HT3, 5-HT1D, and 5-HT7 antagonist, a 5-HT1A agonist, and a 5-HT1B partial agonist, is a recently launched antidepressant approved by the United States Food and Drug Administration for treating adult major depressive disorder. Although hematological adverse effects have been associated with antidepressants, massive bleeding is a rare but potentially life-threatening complication. In this case report, we present a young woman who experienced abnormal bleeding tendencies, with manifestations including tarry stools, ecchymosis, and massive uterine bleeding, while undergoing vortioxetine treatment.

Selective serotonin reuptake inhibitor (SSRI) antidepressants such as fluoxetine are used in combination with the medical psychostimulant methylphenidate (Ritalin) in a variety of treatments in children and adults. Unintended co-exposure to these psychotropic medications also occurs in patients on SSRIs who abuse methylphenidate as a "cognitive enhancer" or recreational drug. Preclinical research shows that SSRIs such as fluoxetine when given in conjunction with methylphenidate potentiate addiction-related gene regulation by methylphenidate in the striatum, consistent with the known facilitatory role for serotonin in psychostimulant-induced neuronal and behavioral changes.

Major depressive disorder (MDD) is among the most prevalent psychiatric conditions and a leading cause of disability worldwide. MDD presents a diverse range of symptoms that significantly impact personal, societal, and economic dimensions. Despite the availability of numerous antidepressant treatments (ADTs) targeting different molecular mechanisms, a substantial proportion of patients experience inadequate response, presenting a considerable challenge in MDD management.
