Research on esketamine for depression has surged from 2015 to 2024, totaling 925 articles, with 286 published in 2024 alone. The United States contributed the most publications (308), followed by China (260) and Canada (114). Leading journals include the Journal of Affective Disorders, Frontiers in Psychiatry, and the International Journal of Neuropsychopharmacology. Key authors are McIntyre, Roger S (52 publications), Hashimoto, Kenji (49), and Rosenblat, Joshua D (41). Prominent research keywords over the last decade are "treatment-resistant depression," "efficacy," "antidepressant," and "suicidal ideation." Current focus remains on assessing long-term safety, while a large disparity in research resources persists between developed and low- and middle-income countries.
