A single dose of esketamine quickly reduced suicidal thoughts and depression in people with treatment-resistant depression. Preliminary evidence suggests that men and women may respond differently, indicating that personalized treatment approaches could improve results. More research is needed to confirm these gender differences, examine long-term effects, and understand the biological reasons behind them.
Trauma-related autobiographical memories can become intrusive and distressing, contributing to post-traumatic stress disorder (PTSD) and depression, including treatment-resistant depression (TRD). Intranasal esketamine, an approved rapid-acting treatment for TRD, may create conditions that facilitate psychotherapeutic work on traumatic memories. This narrative review synthesizes evidence on ketamine and esketamine for PTSD and trauma symptoms, distinguishing intravenous ketamine studies, intranasal esketamine data, and combination approaches with psychotherapy.
