Antidepressant Companies Matrix by Mordor Intelligence
Our comprehensive proprietary performance metrics of key Antidepressant players beyond traditional revenue and ranking measures
The Top-5 list can differ from the MI Matrix because revenue scale often reflects broad portfolios, legacy products, and country breadth rather than today's depression-specific capability. This MI Matrix places more weight on observable signals such as regulated clinic readiness, formulary pull-through, site footprint, and late-stage trial momentum in treatment-resistant depression. Many decision teams also need direct answers on who is driving clinic administered ketamine pathways and who is closest to filing psychedelic-derived therapies with regulators. They also need clarity on which firms can keep generic SSRI and SNRI supply stable when inspections, import alerts, or pricing shocks hit. The MI Matrix by Mordor Intelligence is better for supplier and competitor evaluation than revenue tables alone because it rewards execution evidence and near-term delivery capacity, not just scale.

The MI Matrix benchmarks top Antidepressant Companies on dual axes of Impact and Execution Scale.
Analysis of Antidepressant Companies and Quadrants in the MI Competitive Matrix
Comprehensive positioning breakdown
Johnson & Johnson (Janssen)
Spravato performance keeps the neuroscience franchise visible even when many oral options face generic pressure, and that supports disciplined investment choices. USD 1.2 billion in Spravato sales for the first nine months of 2025, reported by the leading company, signals durable clinic demand despite monitoring requirements. Because dosing happens in certified settings with observation, regulatory expectations still shape throughput and staffing is a real constraint. If payer rules ease for repeat dosing, the upside is meaningful, but any safety signal would quickly compress utilization and reputational trust.
H. Lundbeck A/S
DKK 22,004 million in 2024 revenue, disclosed by the company, reflects revenue concentration that can be a strength for the leading player when core products keep growing across multiple regions. Brintellix/Trintellix and Rexulti are among the largest products by revenue, supporting continued promotional focus. The regulatory burden is manageable versus clinic-administered models, but hopes for labeling expansion still depend on clean trial execution and payer acceptance. If demand in major European countries softens, the company can still lean on U.S. performance, yet any supply disruption would hit confidence quickly.
Otsuka Pharmaceutical Co., Ltd.
Partner economics shape the story, because co-development can accelerate adoption but also splits control over claims and sequencing. Otsuka, a major player in CNS, co-developed Rexulti, and FDA reviewers raised efficacy concerns in July 2025 for a brexpiprazole plus sertraline PTSD application, which shows how quickly momentum can be challenged. Otsuka and Lundbeck continued to publish post hoc analyses in 2024 that reinforced durability narratives in neuropsychiatric use, which helps clinician education. If an additional depressive-related label were secured, it could widen prescriber pull, but an adverse advisory outcome would likely slow investment.
Teva Pharmaceutical Industries Ltd.
Scale and redundancy in manufacturing can be decisive when older antidepressants still require reliable global supply. The company, a major supplier, reported 2024 revenue of USD 16.5 billion and continued portfolio optimization, including classifying its API business as held for sale at year-end 2024. It also described increased R&D spending tied partly to a late-stage neuroscience pipeline, which is the main innovation bridge back into depressive care. If supply tightens for key generics, Teva can gain volume quickly, but the operational risk is disruption during footprint changes.
Pfizer Inc.
Scale is useful in depressive care mostly through global commercial infrastructure and compliance systems that support large formularies. Pfizer's 2024 Form 10-K shows the company's ongoing product-level revenue disclosure practices and supports financial durability for multi-year commitments. A realistic upside scenario is deploying that infrastructure to support next-generation neuropsychiatric assets through partnerships rather than heavy internal build. The risk is that focus remains concentrated on larger growth drivers, leaving depressive care as a low-investment category unless a clear differentiated candidate emerges.
GlaxoSmithKline plc
Capital allocation is increasingly selective, which can be positive when it forces clarity on where clinical differentiation is most likely. GSK reported 2024 sales of 31.4 billion and highlighted continued investment in R&D and longer-term growth planning in its 2024 results materials. For antidepressant portfolios that skew mature, trusted quality systems and wide country access are advantages, while the weakness is limited recent product novelty in depression. If payers tighten step therapy rules further, older brands may see faster substitution, so lifecycle management becomes the core risk.
Frequently Asked Questions
What separates NMDA and ketamine pathway leaders from everyone else?
Clinic workflow is the differentiator, not the molecule alone. Look for certified site density, staff training throughput, and repeat-dose logistics.
What should buyers look for in a psychedelic program partner?
Prioritize Phase 3 readiness, protocol discipline, and a credible plan for site training and patient monitoring. Also check controlled-substance handling plans country by country.
How do REMS-style requirements change scaling economics?
They shift value toward operators who can run predictable appointments and observation time. That favors systems with stable staffing and payer authorization expertise.
What signals indicate a generic manufacturer can keep antidepressant supply steady?
Inspection history, remediation speed, and redundant manufacturing nodes matter most. A single import alert can disrupt many chronic refill products at once.
Why do some firms score high on Innovation but lower on Financials?
Early-stage depression programs can show strong clinical signals while still burning cash. Execution strength then depends on funding runway and partner quality.
How should health systems compare hospital, specialty clinic, and telepsychiatry channels?
Match channel to dosing intensity and monitoring burden. Clinic administered therapies usually need specialty settings, while oral generics fit retail and mail delivery.
Methodology
Research approach and analytical framework
Evidence was triangulated from company investor releases, SEC filings, and credible journalism. Public-company disclosures were used where possible, and private-firm signals relied on trial milestones and announced partnerships. Indicators were limited to the defined scope and 2023+ time window. When direct depression-only financial splits were unavailable, proxy signals were used conservatively.
Counts certified clinic pathways, pharmacy channel reach, and multi-region availability of depression therapies.
Reflects prescriber and payer trust for controlled substances, REMS-like oversight, and chronic refill reliability.
Uses depression-therapy revenue and volume proxies from filings, product sales lines, and disclosed prescription momentum.
Weighs finished-dose capacity, inspection stability, and ability to maintain steady supply of SSRIs and SNRIs.
Prioritizes 2023+ Phase 2/3 progress, label wins, and novel mechanisms for treatment-resistant depression.
Assesses ability to fund trials, withstand pricing pressure, and invest in access programs and medical education.
