Objective
To review the efficacy and safety of frovatriptan (F) vs. rizatriptan (R), zolmitriptan (Z) and almotriptan (A), in women with menstrually related migraine (IHS criteria) through a pooled analysis of three individual studies.
Methods
Subjects with a history of migraine with or without aura were randomized to F 2.5 mg or R 10 mg (study 1), F or Z 2.5 mg (study 2), and F or A 12.5 mg (study 3). The studies had an identical multicenter, randomized, double blind, cross-over design. After treating 3 episodes of migraine in no more than 3 months with the first treatment, patients had to switch to the next treatment for other 3 months.
Results
346 subjects formed the main study intention-to-treat population; 280 of them were of a female gender (81%) and 236 in the fertile age. A total of 187 out of the 236 eligible women (79%) treated at least one episode of menstrual migraine with both medications and were thus included in the present subgroup analysis. Rate of pain free at 2, 4 and 24h was 23%, 52% and 67% with F and 30%, 61% and 66% with comparators (p=NS). Pain relief episodes at 2, 4 and 24h were 37%, 60% and 66% for F and 43%, 55% and 61% for comparators (p=NS). Rate of recurrence was significantly (p<0.05) lower under F either at 24h (11% vs. 24% comparators) or at 48h (15% vs. 26% comparators). Number of menstrual migraine attacks associated with drug-related adverse events was equally low (p=NS) between F (5%) and comparators (4%).
Conclusions
According to our analysis of individual studies F is as effective as other triptans in the immediate treatment of menstrual migraine attacks, but exhibits a more sustained effect.
