BackgroundAlthough migraine is a disabling neurological condition that causes important disability, it remains an area of underdiagnosis and undertreatment worldwide. The aim of this study was to depict the burden of the unmet medical needs in migraine treated with triptans in a large Italian population.MethodsA 2-year longitudinal analysis of migraineurs with unmet medical needs on treatment with triptans was performed. The studied cohort consisted of subjects with ≥4 triptan dose units per month, selected from the general population These patients were stratified into: possible Low-Frequency Episodic Migraine (pLF-EM: 4-9 triptan dose units per month), possible High-Frequency Episodic Migraine (pHF-EM: 10-14 triptan dose units per month) and possible Chronic Migraine (pCM:> 14 triptan dose units per month). The first follow-up year was analysed to describe the use of preventive therapies, the second year to describe the ≥50% reduction in triptan use.ResultsOf 10,270,683 adults, 8.0 per 1000 were triptan users and, of these, 38.2% were migraineurs with unmet medical needs, corresponding to 3.1 per 1000 adults. By stratifying for the number of triptan dose units per month, 72.3% were affected by pLF-EM, 17.4% by pHF-EM, and 10.3% by pCM. In this cohort, 19.1% of individuals used oral preventive drugs and 0.1% botulinum toxin. Triptan use reduction was found in 22.3% individuals of the cohort, decreasing with the intensification of need levels (25.8% pLF-EM, 13.6% pHF-EM, 12.0% pCM).ConclusionsThis real-life analysis underlined that the unmet medical needs concern a large part of patients treated with triptans and there is an undertreatment with preventive therapies whose benefit is insufficient, which may be due to the lack of effective preventive strategies, probably still reserved to severe patients. This study allows forecasting the actual impact of newest therapeutic strategies aimed to fill this gap.
