Depression with significant anhedonia can contribute to the development and complicate the treatment of opioid use disorder (OUD).1–3 Pramipexole, a dopamine receptor agonist with high affinity for D3 receptors and with possible additional anti-inflammatory properties, has been shown to be effective in treating anhedonic depression.4–7 We report a case in which pramipexole rapidly improved depression and anhedonia symptoms in a patient on buprenorphine and an antidepressant.
Case Report
Mr A is a 38-year-old man with a ≥ 10-year history of OUD, major depressive disorder, post-traumatic stress disorder (PTSD), and chronic pain, who was admitted to a residential rehabilitation program for treatment of OUD and PTSD. His opioid use started with prescribed hydrocodone for pain, then transitioned to heroin and fentanyl.
Previously, he was treated while in legal custody with buprenorphine 24 mg/d in dosing 3 times/d. After his release, he quickly relapsed back to high-dose fentanyl use. He had not taken buprenorphine or any of his other medications for the 3 weeks prior to admission.
After buprenorphine was reinitiated and titrated up to previous dosing, his Montgomery-Asberg Depression Rating Scale (MADRS)8 scores were 16 and 17 one week apart, indicating mild depression. Duloxetine was started and titrated up to 60 mg. Despite antidepressant treatment, he again scored 17 on the MADRS. He continued to endorse cravings, pain, anhedonia, amotivation, and poor sleep.
Three weeks after duloxetine was initiated (6 weeks after admission), pramipexole was started at 0.25 mg dosed at night and titrated up to 1.0 mg over the course of a week. After a week on pramipexole, he reported improved mood and motivation, as well as increased ability to participate in the milieu. He reengaged in hobbies and stated, “I don’t feel like I have to force a smile anymore.”
Pramipexole was further increased to 1.5 mg/night in an attempt to reduce pain.7,9 We monitored pain severity via the Brief Pain Inventory,10 and pramipexole effect was modest. However, overall functioning and participation in daily life improved dramatically, as shown by an 18-point improvement in the 10-item Recovering Quality of Life questionnaire (ReQoL-10).11 Approximately 6 weeks after reaching 1.5 mg of pramipexole, his MADRS score was 9. We also used the Leuven Affect and Pleasure Scale (LAPS)12 to measure changes in negative and positive affect, hedonic function, cognitive and overall function, meaningfulness, and happiness (Figure 1). Mr A tolerated pramipexole well and only reported occasional morning nausea during the rapid initial titration. He denied subjective experience of disinhibition and impulsivity, which was confirmed by clinician observation. He endorsed improved sleep and cravings.
Discussion
The initial results of our case suggest that pramipexole can be a rapid and effective adjunctive treatment in patients with anhedonic depression, chronic pain, and OUD who are receiving buprenorphine therapy and are not responding well to an antidepressant.
Improvement in MADRS, ReQoL-10, and LAPS scores show not only decreased depressive symptoms, but also increased overall enjoyment of life and increased functionality. Additionally, this increase in quality of life occurred despite no significant improvement in pain via Brief Pain Inventory scores. These scores reflect the subjective improvement stated by the patient and observed by the providers. Furthermore, since anhedonia is associated with increased risk of relapse and dropping out of treatment, we believe the addition of pramipexole contributed to Mr A’s successful stay in residential treatment and ongoing sobriety, despite multiple risk factors such as a recent relapse, PTSD, and criminal charges.
