Welcome to Part Three of this series on migraine attacks. Today, I am stepping into the world of guest blogging and am delighted to host Inside The Brain’s first guest blogger – Dr Chad Beyer, who explains how the race is on to discover better and safer drugs to diminish migraine pain and prevent future attacks.
If you belong to the 1 in 4 households in theUnited States or the 11% of the world who suffer from acute migraines, you have about a 50/50 chance of being prescribed a “triptan” or a non-steroidal anti-inflammatory drug (NSAID) such as aspirin. Unfortunately for patients, both treatment options are routinely accompanied by severe safety liabilities. Most people are probably aware of the gastrointestinal and cardiovascular side-effects associated with NSAIDs and selective COX-2 inhibitors – if you are not, just Google Vioxx or Celebrex!
Collectively, the triptans (exemplified by sumatriptan) are not a squeaky clean class of molecules either and bring with them potential cardiovascular liabilities that make them contraindicated in roughly 20% of migraineurs who are also diagnosed with high blood pressure, angina and several other cardiovascular-related events. This is due to the non-specific vasoconstriction induced by triptans – which is great in the middle cerebral and meningeal arteries where migraines are suspected to occur but notsomuch in other arteries within the cardiovascular, pulmonary and renal systems.
Therefore, despite the marked advances in our understanding of the complex biology of migraines (i.e., the vasoconstriction and neuropeptide (CGRP) hypotheses) and the discovery of a variety of prescription medicines used to manage the clinical symptoms (the triptans), there remain considerable unmet needs requiring a focused eye towards improving both the efficacy and safety profile of future migraine treatments.
Although commercially-available triptans only work in about 40% of migraine patients, they continue to be the market leader used to combat migraine. My opinion is that not all migraines are created equal and if you have found a treatment strategy (e.g., a triptan) that works well for you and one that you can tolerate – then by all means, keep doing what you are doing!
However, there is clear evidence that exists to support the discovery and development of therapies designed to work by a novel mechanism to treat migraine. We (and other companies focused on this problem) are excited about the possibility to bring to the world a novel medication that demonstrates superior safety and possibly efficacy for the millions of patients suffering from acute migraine.
