Schatzberg AF, Mathew SJ. The why, when, where, how, and so what of so-called rapidly acting antidepressants. Neuropsychopharmacology 2024; 49:189-196. [PMID: 37460770 PMCID: PMC10700639 DOI: 10.1038/s41386-023-01647-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/10/2023] [Revised: 06/22/2023] [Accepted: 06/27/2023] [Indexed: 12/08/2023]
Abstract
Developing antidepressants that are not only more effective but are rapidly acting is the Holy Grail for psychiatry. We review multiple issues that arise in determining rapid responses in antidepressant trials. The current status of purportedly rapid acting agents is first reviewed. Then, a number of key questions/issues are addressed: Is there a unifying definition for rapid response across studies? Should rapid response criteria be based on required measurable effects on overall improvement? On specific symptoms such as psychomotor retardation, depressed mood, or anhedonia? In associated symptoms such as anxiety or insomnia? When should onset be considered rapid-by Day 3? Day7? Day 14? If there is a rapid response, for how long should the effects be maintained? Is maintenance of effect dependent on continuing the medication? Is rapid response associated with specific mechanisms of action? Do the mechanisms of action suggest possible risk for drug abuse? How important is rapid response really in an often chronic or recurrent depressive disorder? In which types of patients could rapid response be particularly important? What are the study design issues that need to be considered for assessing rapid response, including: selection of specific types of depressed patients, multiple doses of drug studied, designation of primary and secondary outcome measures, specific time points at which to determine efficacy, requirements for demonstrating durability, etc. A framework for approaching this complex area is developed for both researchers and clinicians.

Psychiatry Res 2024; 331:115604. [PMID: 38064911 DOI: 10.1016/j.psychres.2023.115604] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 11/07/2023] [Accepted: 11/10/2023] [Indexed: 01/02/2024]
Abstract
The current study evaluated the effectiveness of intravenous ketamine treatment for suicidality in a community-based clinical sample of 295 outpatients (mean age= 40.37; 58.6 % male). We conducted growth mixture modeling to estimate latent classes of changes in symptoms of suicidality measured by the Concise Health Risk Tracking - Self-Report (CHRT-SR) across five infusions in a two-week course of treatment. Best-fit indices indicated three trajectory groups demonstrating non-linear, quadratic changes in CHRT-SR scores during ketamine treatment. The largest group of patients (n= 170, 57.6 %) had moderate CHRT-SR scores at baseline and showed gradual improvement during treatment. The other two groups of patients had severe CHRT-SR scores at baseline and diverged into one group with no improvement throughout treatment (n = 63, 21 %) and one group with rapid improvement (n = 62, 21 %). Of the clinical and demographic variables available and tested, only higher scores pertaining to active thoughts of death and/or plan were found to predict which of the patients with severe CHRT-SR scores at baseline would not benefit from treatment. The present study provides an important contribution to the knowledge of ketamine's effects on symptoms related to suicide over time. providing support for the possible effectiveness of ketamine in a proportion of patients.
