ObjectiveThis study was conducted to characterize prescription refill patterns for triptans among European patients with new prescriptions of triptans.BackgroundPersistency with prescriptions of triptan monotherapy for migraine headache among newly prescribed users in European primary-care practices has not been well described.MethodsUsing electronic medical databases in the UK (N = 3618), France (N = 2051) and Germany (N = 954), we conducted a retrospective cohort analysis to identify refill patterns over 2 years among migraineurs receiving new prescriptions of triptan monotherapy in 2006.ResultsOf all patients, >33% of migraineurs with new triptan prescriptions received ≥1 refill of their index triptan prescriptions (UK, 44.3%; France, 34.2%; Germany, 37.7%). More than 50% never received index-triptan refill prescriptions (UK, 55.7%; France, 65.8%; Germany, 63.3%). Small proportions of patients (<7.0%) switched to alternative triptans, and even fewer switched to different prescription-medication classes (UK and Germany, 2.3%; France, 4.0%). More than 48% of patients received no further prescriptions for migraine after index prescriptions (UK, 48.5%; France, 54.9%; Germany, 54.7%). After the second year, >83.0% of patients in each country had no further prescriptions for migraine medications, <14.0% remained persistent with index prescriptions, <4.0% switched to other triptans, and <3.0% switched to alternative medication classes.ConclusionsIn migraine patients who received new prescriptions of triptan monotherapy from their primary-care physicians, poor triptan prescription refill frequency was observed in Europe. Although consistent with potential clinical challenges in migraine management, our findings should be interpreted with caution given certain inherent limitations associated with the database study design. Further research is warranted to confirm our findings and to identify reasons for, or predictors of, triptan discontinuation.
