Triptan Meta-Analysis:Background Objective • To evaluate the available clinical trial evidence base for oral triptan (5HT1B/1D agonist) drugs and provide a foundation for their use in managing acute migraine. Background • Given that seven different triptans are clinically available, physicians need evidence-based guidelines to select the triptans with the highest likelihood of success. Methods • Clinical trial databases for randomized and active-controlled studies provided by manufacturers of rizatriptan, sumatriptan, zolmitriptan, eletriptan, almotriptan, and naratriptan. • This independent analysis includes 53 trials with a total of 24,089 patients and is published in the Lancet.

Tolerability and Safety Profile • All oral triptans in the meta-analysis were well tolerated. • “No triptan was demonstrably safer than the others.” • Safety can only be reliably assessed after large-scale and long-term clinical exposure. Adapted from Ferrari MD et al. Lancet 2001;358:1668-1675.

Triptan Meta-Analysis:Implications for Migraine Treatment • Largest independent analysis of migraine therapies provided evidence-based foundation for choosing a first-line triptan. • At marketed doses, all oral triptans were effective and well tolerated. • Rizatriptan 10 mg demonstrated high efficacy across key endpoints.* • Rizatriptan 10 mg offered a high likelihood of success “when consistent and rapid freedom from pain is desired.” Adapted from Ferrari MD et al. Lancet 2001;358:1668-1675. *Comparison of recommended initial doses in SPC and standard comparator in the meta-analysis (sumatriptan 100 mg).
