We present the results of treatment with subcutaneous sumatriptan in migraine attacks. The study comprised forty-two patients suffering from migraine both with and without aura, with migraine attacks not susceptible to analgesics, non-steroid anti-inflammatory drugs (NSAID), ergotics or else intolerance to the same. Two groups were independently analyzed, one consisting of ten patients who had menstrual migraine continually for twelve months, the other consisting of thirty-two patients suffering from migraine with and without aura for six months. We assessed the effectiveness of the drug (reduction in the intensity and duration of the attack, action, speed, recurrence) and tolerance (adverse effects). The effectiveness of sumatriptan in relieving headache was 75.9% (80% in the case of the menstrual migraine group and 71.8% in the case of the migraine with and without aura group). This effectiveness was maintained in a similar fashion by analyzing independently the first and last months of treatment. Adverse effects were noted in 38.7% of patients treated (40% for the menstrual migraine group, 37.5% for those with migraine with and without aura). The most frequent effects were pain at the point of injection, a feeling of general tiredness, nausea and a sensation of tension in the neck or chest. These effects were largely slight and short lived. No serious adverse effects were reported. A long term analysis carried out on the menstrual migraine group shows the efficacy of sumatriptan is kept up, with improved tolerance of the drug and a decrease in the number of negative side effects noted.(ABSTRACT TRUNCATED AT 250 WORDS)

We conducted an investigation of migraine headache in a general population of Mexican-Americans living in San Diego county. Specific headache triggers were reported and analyzed, the most frequently reported for females with migraine being missing meals (58.9%), weather changes (54.4%), menstruation (53.6%), post-crisis letdown (52.7%), and fatigue (51.8%). The most frequently reported trigger factors for migraines reported by males were fatigue (58.8%), sleep (as a precipitating factor) (56.3%), post-crisis letdown (41.2%), and weather changes (37.5%). Trigger factors were further evaluated using stratification by presence or absence of Raynaud's phenomenon (RP), menstrual migraine, family history of migraine, and by migraine type. Odds ratios and 95% confidence intervals were calculated. These results suggest that subjects with migraine and RP (perhaps indicative of a systematic vascular tone disorder) and those with menstrual migraine (indicative of sensitivity to hormonal changes) may overall be more sensitive to certain environmental stimuli, particularly those involving change in the internal environment.

Two randomised, double-blind, parallel-group, placebo-controlled clinical trials were conducted to assess the efficacy of sumatriptan tablets, 50mg and 100mg, for treatment during the mild-pain phase of a menstrually associated migraine among patients who typically experienced moderate to severe migraine preceded by an identifiable phase of mild pain. Subjects (n = 403 in Study 1 and n = 349 in Study 2) treated one menstrually associated migraine on an outpatient basis. The results demonstrate that sumatriptan tablets, 50 mg or 100 mg, were significantly more effective than placebo at conferring pain-free response 1 h and 2 h post-dose; migraine-free response (i.e. no pain and no associated symptoms) 2 h post-dose; returning patients to normal functioning 2 h post-dose; and conferring sustained freedom from pain from 2 through 24 h post-dose. Although the studies were not designed or statistically powered to show differences between the sumatriptan doses, a trend for slightly higher efficacy was observed for the 100-mg dose compared with the 50-mg dose on many measures. Both doses of sumatriptan were well-tolerated. The only adverse events reported in more than 2% of subjects in a treatment group were nausea, paresthesia, dizziness and malaise/fatigue, all of which were reported at incidences comparable to or slightly higher than those with placebo. Considered in the context of other findings, these data suggest that--with menstrually associated migraine as with non-menstrual migraine--optimal therapeutic benefit of sumatriptan tablets may be realised when they are administered during the mild-pain phase of an attack rather than delaying treatment until headache is moderate or severe.

Frovatriptan is an orally active 5-hydroxytryptamine (5-HT) receptor agonist which binds with high affinity to 5-HT(1B) and 5-HT(1D) receptors. Earlier clinical trials demonstrated that frovatriptan 2.5 mg is significantly more effective than placebo in the acute management of migraine and its associated symptoms. More recently, frovatriptan was shown to be effective in the management of menstrual migraine. The incidence of menstrual migraine in subjects receiving frovatriptan 2.5 mg twice daily during the six day perimenstrual period was 41% compared with 67% with placebo. Frovatriptan treatment is generally well tolerated. The most commonly reported adverse effects were dizziness, paresthesia, dry mouth, and fatigue. Pharmacologic studies demonstrated that frovatriptan is cerebroselective. Its selectivity for cerebral vessels lessens the potential for undesirable peripheral effects. Frovatriptan has a terminal deposition half-life of approximately 26 hours, which appears to be independent of age, gender, and renal function. This imparts that frovatriptan may be particularly well suited to patients with prolonged migraines and those who suffer migraine recurrence. Frovatriptan does not alter cytochrome P450 (CYP450) isoenzymes, as such it is unlikely to affect the metabolism of other drugs. No dosage adjustments are necessary based on age, renal, or mild to moderate hepatic impairment. Apart from its efficacy in the acute management of migraine, frovatriptan is an effective agent when used as either acute therapy or as intermittent prophylaxis therapy of menstrual migraines, particularly in women who do not respond to conventional therapies.
