Abstract | BACKGROUND: METHODS: A retrospective analysis of patients prescribed either droxidopa or midodrine was conducted using the Symphony Health Solutions database (Symphony Health Solutions, Phoenix, AZ, USA). Inclusion criteria were (1) a pharmacy insurance claim in at least 16 consecutive quarters from mid-2014 to 2018 and (2) an active prescription for droxidopa or midodrine of ≥30 days' duration during that period. Treatment persistence was defined as the time to the first break in drug coverage of ≥45 days and was capped at 365 days. RESULTS: Data from 2305 patients who received droxidopa and 117,243 patients who received midodrine were included in this analysis. Median (95% CI) treatment persistence was significantly longer in the droxidopa cohort versus the midodrine cohort (303 [274-325] vs 172 [169-176] days; P < 0.001). After adjustment for confounding factors, patients using droxidopa monotherapy (i.e., without any concomitant midodrine and/or fludrocortisone use) were 16% more likely to be persistent at any time point than patients using midodrine (P < 0.001). CONCLUSIONS: In this real-world data analysis, patients using droxidopa without concomitant medications for OH were more likely to remain on treatment than patients on midodrine.
