Migraine league table:

acute treatments and 24 hour sustained response

There are a number of treatments available for acute migraine. This page summarises their efficacy in several ways. The information is drawn predominantly from systematic reviews of comparable trials. The important points that make the treatments comparable are as follows:

So what we have here is a consistent data set. We can tell it is consistent by examining the placebo responses for the treatments - they are all about 20%.


Dangers of over-interpretation

Information from league tables is sometimes over-interpreted. It should not be used to exclude treatments from formularies, for instance. rather we should celebrate the fact that we have so many effective remedies. Some arguments against over-interpretation follow:

Patient choice, and professional choice, will be influenced by many factors. Analgesic efficacy is only one. Moreover, relative efficacy should be used as a tool to guide personal and professional choice, and not be used as a rule to exclude certain types of treatment because of cost or convenience.

So please use the league table as you would a walking stick. Use it to help you and not to beat others.


Information provided

The information here has been collected from reviews. The table gives all the information we thought relevant, including the number of trials and patients from which the table is drawn. The two figures show the results graphically for NNTs, and for the proportion of patients with pain free at two hours. In the figures subcutaneous treatments are in red , and intranasal treatments in green ; all other treatments are oral, with oral treatments that are not triptans in yellow.
