Pramipexole for MDD

I appreciate Dr. Espejo’s recommendations for treating patients who experience limited response from initial antidepressant therapy (“Treating major depressive disorder after limited response to an initial agent,” Current Psychiatry, October 2021, p. 51-53). I would like to add that pramipexole, a dopamine receptor agonist, can also alleviate depression. A meta-analysis concluded that patients receiving monotherapy or augmentation with pramipexole (mean maximum dose 1.62 mg/d) achieved response or remission of depression.¹ In an observational study of 116 patients with unipolar or bipolar depression, nearly 75% experienced response and 66% achieved remission with pramipexole augmentation (median maximum dose 1.05 mg/d).² Pramipexole is usually well-tolerated, although patients may experience nausea, somnolence, headache, and constipation, and they should be cautioned about the risk for compulsive behaviors and psychosis.
