OBJECTIVE: To compare the proportion of patients who prefer rizatriptan orally disintegrating tablet (ODT) 10-mg to sumatriptan 50-mg tablet. BACKGROUND: Migraineurs express treatment preference based on a variety of attributes including the speed of pain relief and medication formulation. Rizatriptan ODT is an orally disintegrating formulation of rizatriptan, a selective 5-HT1B/1D receptor agonist. This study was conducted to determine patient preference between rizatriptan ODT 10-mg and sumatriptan 50-mg tablet for the acute treatment of migraine. METHODS: This was a multicenter, randomized, open-label, two-period crossover study conducted in the United States with 524 enrolled patients. Patients treated a single moderate or severe headache in each treatment period. Patients treated one migraine with either rizatriptan ODT 10-mg or sumatriptan 50-mg tablet, then treated a second migraine with the alternate therapy. Patients completed diary assessments at baseline, and 30, 45, 60, 90, and 120 minutes postdose and rated headache severity on a 4-point scale (0 = none, 1 = mild, 2 = moderate, and 3 = severe). At the final study visit following treatment of their second migraine, patients expressed preference for one of the two study medications by completing an interviewer-administered Global Preference Question and then responded to a self-administered series of questions to capture their most important reason for preferring one study medication over the other. Safety measurements were recorded through standard adverse experience reporting. RESULTS:Three hundred eighty-six patients treated two migraine attacks. For those patients who expressed a preference for either rizatriptan ODT or sumatriptan (n = 374), the percentage of patients who preferred rizatriptan ODT 10-mg (57%, n = 213) was significantly greater than those who preferred sumatriptan 50-mg tablet (43%, n = 161) (P<.01). For those patients who treated two migraine attacks and had drug severity measures for both attacks (n = 384), a significantly greater percentage of patients reported pain relief after taking rizatriptan ODT than sumatriptan at the 45- and 60-minute time points (38% versus 29% and 58% versus 49%, respectively) (P<.01). In addition, a significantly greater percentage of patients taking rizatriptan ODT reported a pain-free status at the 60- and 120-minute time points (23% versus 17% [P<.05] and 60% versus 52% [P<.01], respectively). Both rizatriptan ODT and sumatriptan were well tolerated. CONCLUSIONS: A significantly greater proportion of patients preferred rizatriptan ODT 10-mg to sumatriptan 50-mg tablet for the acute treatment of migraine. Efficacy and safety data are consistent with the preference findings.
