Risk factors for headache recurrence after sumatriptan: a study in 366 migraine patients.
Headache recurrence (HR) is the major limitation of sumatriptan in the acute treatment of migraine attacks. The risk of HR is mainly patient-dependent. We analyzed, in 366 migraine patients, clinical differences between patients who always have HR and patients who never have HR. We found remarkably few differences. HR more frequently occurred in patients with more severe attacks and longer untreated attack duration; in patients who experienced a sensation of a subclinically ongoing attack, despite headache relief after sumatriptan; and in females, mainly with menstruation-related migraine, most probably due to the more severe and longer lasting attacks these patients suffer, rather than due to hormonal factors. The incidence of HR was, among other factors, not related to the (other) clinical effects of sumatriptan, the timing of administration within the attack, the duration of use of sumatriptan, pharmacokinetic factors, or whether patients were experiencing HR after use of ergot alkaloids.
