Beta-Blockers medications for the treatment of migraine headaches : an introduction

Beta-blockers, commonly used for treating high blood pressure and other heart issues, are also prescribed to prevent migraines. Beta-blockers are also sometimes called beta-adrenergic blocking agents.

Studies show that beta-blockers reduced migraine frequency in 50% of studied patients.

How beta blockers work

Beta-blockers work to relax and open up blood flow in blood vessels. Changes in blood vessels in the brain are thought to cause migraines, however it is unclear how beta-blockers prevent migraine symptoms. Beta-blockers also block the effect of adrenaline, reduce blood pressure and slows the heart beat.
