SYNOPSISFemale migraineurs frequently report a severe migraine headache a few days prior to, during, or immediately following a menstrual period. Menstrual migraines were identified in a study of 193 migraineurs who participated in a controlled, experimental, outcome study of non-drug treatments for the control of migraine headaches. Participants were required to monitor their daily headache activity and drug usage for 36 weeks and were assigned to one of four groups: (1) No Treatment; (2) Autogenic Phrases; (3) Electromyographic Feedback, and (4) Thermal Feedback. Data were reduced and analyzed using multivariate analysis of variance and covariance. There was a tendency for all groups to improve over the 36 weeks. No significant difference was found among the four groups in headache improvement. (Headache 24:75-78, 1984)

Rizatriptan (MK-462) is a potent 5HTID receptor agonist. This multicenter, double-blind, placebo-controlled, outpatient study investigated the clinical efficacy, safety, and tolerability of rizatriptan (2.5, 5, and 10 mg) as a function of dose for acute migraine. Patients with moderate or severe migraine (n = 417) were treated with placebo (n = 67), rizatriptan 2.5 mg (n = 75), 5 mg (n = 130), or rizatriptan 10 mg (n = 145). Headache severity, functional disability, and migraine symptoms were measured immediately before dosing (0) and at 0.5, 1, 1.5, 2, 3, and 4 h post-dose. Patients were permitted to take a second dose of test drug at 2 h if their headache pain was moderate or severe (i.e., placebo initially-->rizatriptan 10 mg as optional second dose; rizatriptan 2.5 mg, 5 mg, or 10 mg initially-->placebo as optional second dose). An upward dose-response relationship was observed among placebo, rizatriptan 2.5 mg, 5 mg, and 10 mg in the primary efficacy measure of proportion of patients reporting pain relief, i.e., a change in headache severity to "no pain or mild pain" at 2 h post-dose. The relationship was evident even at the first recorded timepoint, 30 min, and was statistically significant at 1.5 h and beyond. At the primary timepoint of 2 h after the initial dose, the proportion of patients reporting pain relief was 47.6% for rizatriptan 10 mg; 45.4% for rizatriptan 5 mg; 21.3% for rizatriptan 2.5 mg; and 17.9% for placebo. Seventy percent of patients on rizatriptan 10 mg reported pain relief at 4 h. Patients who took rizatriptan 5 mg and 10 mg were significantly less functionally disabled than those who took placebo at 1.5 and 2 h post-dose. Rizatriptan 10 mg was consistently more effective than 5 mg, although the differences were not statistically significant. The most frequent clinical adverse events were dizziness, somnolence, and asthenia/fatigue. No patients were discontinued for any adverse experiences and there were no serious adverse experiences.

The tolerability and efficacy of naproxen sodium and of ergotamine tartrate plus caffeine (ergotamine) were compared in the treatment of acute migraine attacks and associated symptoms. In this multicenter, double-blind, parallel study of up to six headaches over a 3-month period, patients took naproxen sodium 825 mg, ergotamine 2 mg, or placebo at the time of the first symptom of an attack; 30 minutes later, if necessary, patients repeated naproxen sodium 275 mg, ergotamine 1 mg or placebo, as appropriate. Rescue medication was allowed 30 minutes following the second dose if needed. Active drugs provided notably better relief of head pain than did placebo; 1 hour following the first dose the difference between naproxen sodium and placebo was statistically significant. Naproxen sodium was as efficacious as ergotamine in the relief of migraine attacks and associated symptoms. Relief of vomiting, nausea, photophobia, and motor symptoms favored naproxen sodium over ergotamine; these differences were statistically significant for nausea and motor symptoms. Ergotamine-treated patients reported more complaints and had more severe and longer-lasting complaints than patients on the other two regimens. Overall tolerance ratings by both investigators and patients indicated that naproxen sodium and placebo were tolerated significantly better than ergotamine.
