Randomized Controlled Trial Multicenter Study
Effect of pain intensity and time to administration on responsiveness to almotriptan: results from AXERT 12.5 mg Time Versus Intensity Migraine Study (AIMS).
To determine whether time-based early treatment, independent of pain intensity, is superior to a pain intensity-based treatment, where patients are asked to treat at least moderate intensity headaches, resulting in a reduction of overall migraine headache duration. ⋯ Total headache duration was significantly shorter in the early treatment group compared to the standard treatment group. Considering time to treatment within a relatively early range of 1 hour or less, efficacy results when treating mild versus moderate pain were similar and both were associated with better outcomes than treatment of severe pain. When considering the prognostic variables of time to treatment and headache pain intensity (limited to moderate vs severe), both were independent predictors, with time to treatment a better predictor of headache duration and rescue medication use, and pain intensity a better predictor of 2-hour pain free and sustained pain free.

Randomized Controlled Trial Multicenter Study
Botulinum toxin type a prophylactic treatment of episodic migraine: a randomized, double-blind, placebo-controlled exploratory study.
This exploratory trial evaluated the safety and efficacy of multiple treatments of botulinum toxin type A (BoNTA; BOTOX, Allergan, Inc., Irvine, CA, USA) as prophylactic treatment of episodic migraine headaches. ⋯ There were no statistically significant between-group differences in the mean change from baseline in the frequency of migraine episodes per 30-day period. There were substantial, sustained improvements during the course of the study in all groups. Multiple treatments with BoNTA were shown to be safe and well tolerated over an active treatment period lasting 9 months.
