Migraine treatment outcomes with rizatriptan in triptan-naive patients: a naturalistic study.
BACKGROUND
The 5-hydroxytryptamine(1B/1D) agonists, or triptans, are the newest class of drugs to become available for the acute treatment of migraine. The class currently includes sumatriptan, zolmitriptan, naratriptan, and rizatriptan. The efficacy of rizatriptan in the acute treatment of migraine has been established against placebo and other oral triptans in controlled comparative trials.


OBJECTIVE
The US Migraine Assessment Protocol (USMAP) collected data on the use of rizatriptan in a naturalistic setting reflecting clinical practice. This paper presents results for patients enrolled in the USMAP study who had never taken a triptan before the study.


METHODS
At enrollment, 216 patients completed a questionnaire describing their responses to their current nontriptan medications. They were then given specially packaged samples of 4 standard 10-mg rizatriptan tablets and 4 orally disintegrating 10-mg rizatriptan tablets (wafers) and were asked to take a different formulation for each of their next 2 attacks, the sequence to be at their discretion. Within approximately 24 hours after taking rizatriptan, patients were to call a toll-free number to report their responses to rizatriptan using an interactive voice-response system.


RESULTS
Within 2 hours after initial dosing of rizatriptan, significantly more patients taking either the rizatriptan tablet or the rizatriptan wafer reported onset of pain relief, had become largely symptom free, and were able to resume usual activities compared with their baseline responses to nontriptans (P < 0.05). In addition, compared with their baseline responses to nontriptans, significantly more patients taking either rizatriptan formulation had mild or no pain 2 hours after dosing (P < 0.05). More than twice as many patients taking the rizatriptan tablets or wafers were either somewhat or very satisfied with the medication compared with their satisfaction with nontriptans (P < 0.05).


CONCLUSIONS
In the naturalistic setting of this study, migraineurs who had not previously taken a triptan medication reported more rapid relief of pain, more effective pain relief, and more rapid resumption of normal activities when taking rizatriptan tablets or wafers than when taking a nontriptan medication. Patients dissatisfied with their current nontriptan migraine therapy may benefit from treatment with rizatriptan.
