Neuropathic Pain Medication and Antidepressant Use after Disability Pension in Patients with Spinal Cord Stimulation for Persistent Spinal Pain Syndrome

Figure 2

Mean daily defined doses (DDDs) of gabapentinoids (a) and tricyclic antidepressants (TCA) (b) and also percent of the maximum dose of serotonin-norepinephrine reuptake inhibitors (SNRIs) (c) 2 y before and 1 y after disability pension (DP) in persistent spinal pain syndrome patients with spinal cord stimulation at KUH. Gabapentinoid users n = 12, TCA users n = 8, and SNRI users n = 6. The mean DDD was calculated as the average of total purchased drugs during the specific six-month period (months: 0–6; 6–12; 12–18; 18–24 before and 0–6; 6–12 after DP). For SNRI drugs, the DDD/day of drug use was related to the maximum daily dose of the same drug. The maximum dose was 120 mg/day for duloxetine and 375 mg/day for venlafaxine.
