It is available in a unique wafer formulation that dissolves rapidly in the mouth and can be taken without liquids, thereby offering patients a very convenient way to take treatment. OBJECTIVE: To investigate the long-term efficacy of rizatriptan 10-mg and 5-mg wafers in migraineurs. SETTING: 19 headache clinics in 5 countries. PATIENTS: 458 patients diagnosed with migraine according to International Headache Society criteria. DESIGN: 6-month, open-label, extension, which followed a double-blind, placebo-controlled study. INTERVENTIONS: Patients were randomly assigned to 1 of 3 treatments for moderate or severe migraines: rizatriptan 10-mg wafer, rizatriptan 5-mg wafer, or "standard care" (usual migraine treatment -- eg, nonsteroidal anti-inflammatory drugs [NSAIDs], analgesics, other triptans). Patients randomized to rizatriptan were blinded to the dose. MAIN OUTCOME MEASURES: Headache severity (none, mild, moderate, severe) and adverse events were recorded on a diary card. RESULTS: 181 patients treated 3393 attacks with rizatriptan 10-mg wafer, 191 treated 3254 attacks with rizatriptan 5-mg wafer, and 86 treated 1582 attacks with standard care. The median number of treated attacks per patient was 16 for rizatriptan 10-mg wafer, 13 for rizatriptan 5-mg wafer, and 14 for standard care. The median patient on rizatriptan 10-mg wafer reported pain relief at 2 hours (reduction of headache from moderate or severe at baseline to mild or none) in 82% of attacks, vs 73% of attacks for standard care (odds ratio [95% confidence interval] = 1.63 [1.14, 2.34], P <.01) and 72% of attacks for rizatriptan 5-mg wafer (OR [95% CI] = 1.60 [1.23, 2.08], P <.001). The median patient on rizatriptan 10-mg wafer was pain free at 2 hours in 46% of attacks, vs 30% of attacks for standard care (OR [95% CI] = 1.50 [1.06, 2.12], P <.05) and 25% of attacks for rizatriptan 5-mg wafer (OR [95% CI] = 1.93 [1.50, 2.49], P <.001). All treatments were generally well tolerated. Compared with standard care, rizatriptan 5-mg wafer was associated with fewer specific adverse events of asthenia/fatigue, back pain, nausea, pharyngeal discomfort, upper respiratory infection, and vomiting (P values <.05), and, compared with rizatriptan 10-mg wafer, fewer overall drug-related adverse events (P <.05). CONCLUSIONS: Rizatriptan 10-mg wafer was more effective than standard care and rizatriptan 5-mg wafer for treating intermittent moderate or severe migraine attacks occurring over periods of up to 6 months. Rizatriptan wafers were well tolerated.
