Frovatriptan as preemptive treatment for fasting-induced migraine
Abstract
OBJECTIVE: To examine frovatriptan's efficacy as preemptive treatment for fasting-induced migraine.
BACKGROUND: Fasting is a common migraine trigger that cannot always be avoided. The development of a short-term preemptive approach would be of benefit. Because of its longer half-life, frovatriptan has been effectively used for short-term daily use to prevent menstrually related migraines and might prove useful in the prevention of fasting-induced migraine.
METHODS: This was a double-blind, placebo-controlled, randomized, parallel-group trial.
SUBJECTS: With a history of fasting-induced episodic migraine were randomly assigned to receive either frovatriptan (5.0 mg) or placebo (ratio 1:1).
SUBJECTS: Took a single dose of study medication at the start of their 20-hour fast. Information about headache intensity, associated symptoms, and use of rescue medication was captured at defined time points from the start of the fast through 20 hours post-fast.
RESULTS: Of the 75 subjects screened, 74 subjects were randomized and 71 subjects completed the study. Demographic characteristics of the placebo and frovatriptan treatment groups were not statistically different. Thirty-three subjects received active drug. Twelve (36.4%) developed a headache between 6 and 20 hours after the start of the fast (1/33 mild, 11/33 moderate or severe). In the placebo group, 18/34 (52.9%) developed a headache (4/34 mild, 14/34 moderate or severe). The difference between the 2 treatment groups did not…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 75 participants or records.
