There is no evidence that any ethnic or racial group has a higher risk of adverse events from triptans or that one triptan has a particular advantage over others in any of these groups purchase 600mg zyvox with visa. Migraine is more common among women than men and in whites than blacks zyvox 600 mg low cost, and peaks in 121 prevalence around age forty cheap 600 mg zyvox visa. We found no trials that included primarily men discount 600mg zyvox free shipping, blacks, or the elderly. However, the manufacturer of rizatriptan provided unpublished data on subgroups based on gender, age (< 40 years compared with! No statistical analyses were performed due to small sample sizes in these subgroups, so these findings should be considered exploratory and interpreted with caution. Age 32, 33 Unpublished data from head-to-head trials provided by the manufacturer of rizatriptan suggested that 2-hour pain relief was higher for rizatriptan 10 mg than the conventional tablet form of sumatriptan 50 mg only in the subgroup of patients who were below 40 years in age, not in the subgroup age 40 and above. In other head-to-head trials rates of 2-hour pain relief were 31, 35, 36 superior for rizatriptan regardless of age. Gender 31-33, 35, 36 Unpublished data from head-to-head trials provided by the manufacturer of rizatriptan suggest that rate of 2-hour pain relief was higher for rizatriptan 10 mg than the conventional tablet form of sumatriptan 50 mg and 100 mg, naratriptan 2. Race 31-33, 35, 36 Unpublished data from head-to-head trials provided by the manufacturer of rizatriptan suggest that rates of 2-hour pain relief were higher for rizatriptan 10 mg than the conventional tablet form of sumatriptan 50 mg and 100 mg, naratriptan 2. In a 12-headache randomized placebo-controlled trial, subcutaneous sumatriptan was equally effective in whites, blacks, Hispanics, and others in relieving headache, reducing 100 disability, and in adverse event rates. The trials enrolled samples similar in age, sex, and migraine history. Eletriptan and zolmitriptan had similarly better 2-hour pain relief, pain-free, and relief of associated symptoms (nausea, photophobia, phonophobia, vomiting); 24-hour recurrence; use of escape medication; and rate of adverse events (asthenia, paresthesia, somnolence) when each was compared with placebo. Outcome rates were within the ranges for eletriptan and zolmitriptan reported in head-to-head trials of predominantly white patients in otherwise similar samples. Triptans Page 42 of 80 Final Report Update 4 Drug Effectiveness Review Project Use of migraine prophylaxis Results of pharmacokinetic trials, mostly in healthy volunteers, have been used to make recommendations for or against dosage adjustment in patients taking propranolol and other antimigraine drugs. Unpublished data from head-to-head trials comparing rizatriptan 10 mg with the 32, 36 conventional tablet form of sumatriptan 50 mg or 100 mg provided by the manufacturer of rizatriptan suggest that in migraineurs rate of 2-hour pain-relief may be affected by whether or not patients use prophylactic migraine medication, especially tricyclic antidepressants or valproate. Rate of 2-hour pain-relief for rizatriptan 10 mg was greater than for the conventional tablet form of sumatriptan 100 mg in patients who were not using any prophylactic migraine treatments. However, in those who were using prophylactic migraine treatments, 2-hour pain- relief was lower for rizatriptan 10 mg. Other Trials of triptans have generally excluded patients who have cardiovascular disease, uncontrolled hypertension, liver disease, and several other conditions. In general, triptans have proved to be as effective for migraine associated with menstruation as for other attacks. A double-blind, placebo-controlled randomized controlled trial 91 demonstrated the effectiveness of subcutaneous sumatriptan in menstrual migraine. Retrospective meta-analysis of randomized controlled trials of rizatriptan, zolmitriptan, and subcutaneous sumatriptan support the view that triptans are equally effective for headache during 124-126 menstruation as in other migraine headches. We identified 1 double-blind randomized controlled trial of a triptan to prevent migraines 127 associated with menses. In this trial, across 4 menstrual periods, more patients treated with naratriptan 1 mg were headache-free than with placebo (23% compared with 8%). An earlier pilot study by the same investigator used sumatriptan for prophylaxis of menstrual migraine, but 128 that study was uncontrolled. In small subgroups of adults with menstruation-associated migraines from 2 head-to-head trials, both rizatriptan 10 mg and the conventional tablet form of sumatriptan 50 mg were superior to placebo in improving rate of 2-hour pain relief. But, in the menstruation-associated migraine subpopulations, rizatriptan 10 mg was no longer statistically superior to sumatriptan 50 32, 33 mg as it was in the study population overall.
