Abstract
Purpose
Treatment‐resistant depression (TRD) can require complex management. The purpose of this paper is to provide an update on the hypothesized neurobiology of depression, and to describe treatment options for patients impacted by TRD.
Conclusions
Recent neurobiological findings support the use of augmenting pharmacological agents, neuromodulation techniques, and esketamine as effective in achieving remission for those with TRD.
Practice Implications
First‐line interventions for depression can be safely managed by primary care providers. Psychiatric advanced practice nurses must be well versed and capable of treating more complicated cases, including TRD, that may require second‐ or third‐line approaches.
