Unipolar Depression | Current Treatment | US | 2020

The drug landscape for major depressive disorder (MDD) consists of numerous safe and effective treatment options, many of which are available as inexpensive generics. Agents for treating MDD span multiple drug classes, most notably selective serotonin reuptake inhibitors (SSRIs) and serotonin / norepinephrine reuptake inhibitors (SNRIs), while other agents, including the newer-to-market Spravato (Janssen Pharmaceuticals’ esketamine), offer distinct mechanisms of action. Treatment is often a trial-and-error process due to the heterogeneous nature of the patient population and the multitude of drugs available to treat depressive symptoms. As such, the MDD treatment paradigm is highly individualized and complex. This report provides physician insights into prescribing decisions in this complex disease.


  • What are the drivers and constraints influencing physicians’ treatment decisions for MDD? How are patients being treated across different lines of therapy?
  • What drives switching to and from specific brands (e.g., Spravato [Janssen Pharmaceuticals], Trintellix [Lundbeck / Takeda])? How has the wide availability of generics, including for aripiprazole (Otsuka Pharmaceuticals, Abilify) and duloxetine (Eli Lilly, Cymbalta), impacted prescribing?
  • To what extent is polypharmacy prescribed for MDD in the United States, and what are physicians’ preferred drug class combinations?
  • How has the use of key MDD therapies changed in the past year, and what changes do physicians expect to their prescribing of these drugs in one year?
