The treatment-resistant depression treatment market is experiencing strong growth, driven by the integration of pharmacological, psychotherapeutic, and technological innovations. According to an October 2023 study by NLM, while antidepressants such as selective serotonin reuptake inhibitors (SSRIs) and dual serotonin and norepinephrine reuptake inhibitors (SNRIs) are still commonly used, their remission statistics have led to the usage of rapid-acting agents (ketamine and esketamine) and multimodal antidepressants (vortioxetine). These treatments target glutamatergic, neuroplastic, and inflammatory pathways. The use of atypical antipsychotics and investigational compounds that target neurotrophic and GABAergic systems also represents another promising alternative for TRD.
Emerging non-pharmacological therapies, particularly refined neuromodulation techniques, such as TMS, ECT, Vagus nerve stimulation (VNS), and deep brain stimulation are also considered effective. Digital therapeutics, including smartphone-based cognitive-behavioral therapy (CBT), interpersonal therapy (IPT) and AI-driven platforms also enable case-based treatment. Hybrid care models that integrate digital interventions with telehealth or personalized support are gaining traction in all regions including rural and underserved areas. Additionally, biomarker-guided research which drives precision medicine approaches offers tailor-made and effective treatments. These advancements provide a comprehensive and custom-made approach to TRD treatment, ultimately driving growth in the treatment-resistant depression treatment market.
The high cost of mental healthcare significantly limits its accessibility. According to a September 2024 NLM study, as many U.S. psychotherapists in private practice did not accept insurance, cash pay rates averaged US $143 per session, leading to overpriced care and restricted access. According to a February 2019 National Mental Health Survey (NMHS), psychiatrist availability in Indian states ranged from 0.05 per 100,000 populations in Madhya Pradesh to 1.2 in Kerala. By 2030, depression is projected to be the leading cause of disease burden in low- and middle-income countries, where mental disorders already account for 19.1% of all health-related disabilities, spurring a vicious cycle of poverty and social decline.
Managing TRD typically requires a combination of pharmacological and non-pharmacological approaches, which can be exorbitant. Hospitalization may be necessary for individuals with suicidal ideation or psychosis, which can be overly costly. According to an April 2022 NLM study, access to essential psychotropic medicines remains a global challenge for all countries. Another NLM paper published in July 2022 stressed that TRD was associated with approximately twice the cost burden of non–treatment-resistant depression. A study stated that esketamine can be cost-effective if its price were reduced from US$ 240 to US$ 140 per dose. These expenses pose significant barriers to treatment, highlighting the urgent need for improved access, better insurance coverage, and effective care strategies tailored to high-need populations.
Technological advancements are driving treatment-resistant depression treatment market growth, with notable initiatives such as the SelecTool project conducted by NLM in July 2024. The project focused on developing an ML tool that integrated clinical, EEG, and blood biomarkers to optimize treatment for TRD. New pharmacological options, such as esketamine, have gained regulatory approval and offer alternative pathways for those unresponsive to traditional antidepressants. Combination therapies are increasingly common, with clinicians augmenting antidepressants with antipsychotics or mood stabilizers to improve outcomes. Somatic therapies such as deep brain stimulation (DBS) are emerging as innovative interventions for severe cases.
AI also plays a vital role in accelerating drug development. In a comprehensive Genomic Press Commentary (review) published in May 2025, researchers identified an enlarged salience network in individuals with depression, which was twice as large as in non-depressed individuals. This neural signature, observed before the symptom onset, can serve as a reliable biomarker for depression risk, offering new opportunities for early detection and intervention. In January 2024, Deliberate AI announced its depression and anxiety model, AI-COA, as the First AI/ML Initiative accepted into the FDA’s ISTAND pilot program to advance drug development. These breakthroughs have shifted the focus beyond the traditional drugs and therapies, opening new avenues in the treatment of TRD.
By drug type, the antidepressants segment is projected to account for 68% of the revenue share in 2025, driven by its high effectiveness, minimal side effects, and broad applications in the treatment of depression and other disorders. Antidepressants increase levels of neurotransmitters, such as serotonin and noradrenaline, in the brain, thereby regulating mood and pain perception. Antidepressants include SSRIs (fluoxetine), SNRIs (venlafaxine), NASSAs (mirtazapine), TCAs (amitriptyline), SARIs (trazodone), and MAOIs (phenelzine). Antidepressants are prescribed for moderate to severe depression rather than mild cases. Zuranolone, approved in 2023 (first oral medication for postpartum depression), offers relief after one or two weeks. These initiatives are anticipated to drive the market over the forecast period.
The NMDA segment is anticipated to witness the fastest growth in the coming years. NMDA receptors are glutamate receptors that control brain signaling and synaptic plasticity. According to an NLM study, NMDA receptors play a key role in conditions such as depression, PTSD, and schizophrenia. While Esketamine (Spravato) is promising and has strong antidepressant effects, safer alternatives with fewer side effects are needed. According to a December 2022 NLM study, NMDAs are vital for synaptic plasticity, supporting both long-term potentiation (LTP) for memory formation and long-term depression (LTD) for forgetting. These factors are making NMDA-based treatments highly popular, thereby driving significant segment growth between 2025 and 2032.
Based on distribution channel, the hospital pharmacies segment is expected to dominate the treatment-resistant depression treatment market, holding a revenue share of over 60% in 2025. Severely affected patients require hospitalization and drug therapy. Hospital pharmacies enable treatment, psychiatric evaluation, and close monitoring of medication effects and side effects. Hospital pharmacists collaborate with psychiatrists, manage complex medication schedules, and promptly handle emergency situations, making them essential to effective TRD care.
The drug stores and retail pharmacies segment is predicted to grow at the fastest CAGR during the forecast period, driven by rising patient demand, an increasing number of retail outlets, and greater financial support from governments and other entities. These factors have led to enhanced investment and expansion in retail pharmacy infrastructure. Some examples are Apollo Pharmacy, CVS Health, and Watsons.
North America is anticipated to lead treatment-resistant depression treatment market, accounting for a revenue share of 40% in 2025. The rising prevalence of mental health issues, such as depression, increased awareness of available treatment options, and government support for managing these conditions, are the key driving factors. The increase in the incidence of mental illness can be linked to various factors, including high-stress work environments, social media impact, growing social isolation among youth, relationship breakdown, and unemployment.
The U.S. market is expected to witness significant growth due to increasing awareness about mental illnesses. According to data by National Alliance of Mental Illness (NAMI), one in five adults and one in six youth in the U.S. are facing mental health challenges yearly, making early intervention and support crucial. According to ScienceDirect March 2024 issue, in 2020, the U.S. had fewer than one mental health facility offering somatic treatment options for TRD per 100,000 adults. Although there was a noted increase in the availability of such treatments between 2014 and 2020, it failed to keep pace with the growing demand, highlighting a significant gap between need and access in TRD care. These unmet needs will definitely drive market growth.
The clinical industry in Asia Pacific is likely to witness the fastest growth in the coming years with expanding healthcare infrastructure and increasing mental health awareness. Government initiatives and public campaigns are boosting demand, while novel therapies such as NMDA receptor antagonists and psychedelics are enhancing the treatment options. The rising prevalence of mental illness, ranging from 4% in Singapore to as high as 20% in Vietnam and Thailand, highlights a significant public health challenge in the region. Community-based initiatives, alongside free counseling services provided by organizations such as the Vandrevala Foundation, iCALL, and Sumaitri, will address unmet needs across various locations, driving treatment-resistant depression treatment market growth.
India and China are the prominent players in the Asia Pacific market. The market is slated to grow at a high CAGR over the forecast period, owing to the increased awareness about the disease and the adoption of breakthrough drugs and therapies such as TMS, ketamine infusions, and esketamine.
