Desvenlafaxine tends to have fewer drug interactions and better tolerability than other MDD drugs; however, its use has not been assessed in the real world.Objective: The aim of the present study is to compare medication persistence and concomitant MDD drug use with branded desvenlafaxine (Pristiq®) compared with antidepressant drug groups classified as 1) branded selective serotonin reuptake inhibitors (SSRIs; ie, escitalopram [Lexapro™]) and selective serotonin–norepinephrine reuptake inhibitors (SNRIs; ie, venlafaxine [Effexor®], duloxetine [Cymbalta®]) and 2) generic SSRIs/SNRIs (ie, escitalopram, citalopram, venlafaxine, fluvoxamine, fluoxetine, sertraline, paroxetine, and duloxetine).Patients and methods: MDD patients (ICD-9-CM codes 296.2, 296.3), with ≥2 prescription fills for study drugs and 12-month preindex continuous enrollment from the MarketScan Commercial Claims and Encounters Database (2009–2013), were included. Time-to-treatment discontinuation (prescription gap ≥45 days) was assessed using the Kaplan–Meier curve and Cox model. Concomitant MDD drug use was compared.Results: Of the 273,514 patients included, 14,379 patients were initiated with branded desvenlafaxine, 50,937 patients with other branded SSRIs/SNRIs, and 208,198 patients with generic SSRIs/SNRIs. The number of weeks for treatment discontinuation for branded desvenlafaxine were longer (40.7 [95% CI: 39.3, 42.0]) compared with other branded SSRIs/SNRIs (28.9 [95% CI: 28.4, 29.1]) and generic SSRIs/SNRIs (33.4 [95% CI: 33.1, 33.7]). Adjusting for baseline characteristics, patients who were prescribed with other branded SSRIs/SNRIs were 31% and generic SSRIs/SNRIs were 11% more likely to discontinue treatment compared with branded desvenlafaxine. In sensitivity analysis, the risk of discontinuation was within 10% of branded desvenlafaxine for branded duloxetine, generic escitalopram, and generic venlafaxine. Concomitant MDD drug use was higher among branded desvenlafaxine patients (43.8%) compared with other branded SSRIs/SNRIs (39.8%) and generic SSRIs/SNRIs (36.4%).Conclusion: MDD patients on branded desvenlafaxine were more persistent with treatment compared with those on other branded or generic SSRI/SNRI therapies. Future research should include assessments of underlying factors on the treatment persistence in MDD patients.
