HOW DO SEROTONIN 5-HT1F AGONISTS WORK?

Serotonin 5-HT1F agonists are abortive agents used for the treatment of acute migraine attacks.

Migraine occurs when a specific nerve in the blood vessels sends pain signals to the brain. As a result, inflammatory substances get released into the nerves and blood vessels of the head, causing dilation and inflammation of these blood vessels.

There are two types of antimigraine agents:

  • Abortive agents: These agents abort an established migraine attack. 
  • Preventive antimigraine agents: These agents are given prophylactically to reduce the number of migraine attacks.

Unlike other abortive agents used for migraine treatment, serotonin 5-HT1F does not cause constriction of blood vessels. Serotonin 5-HT1F binds to serotonin 5-HT1F receptors in the brain to block the release of glutamate. Glutamate is an excitatory neurotransmitter that causes increased brain activity. Studies have shown that increased brain activity in specific areas of the brain causes migraines. Thus, serotonin 5-HT1F receptor agonists alleviate migraines by reducing brain activity without interfering with normal cell function.
