The Mechanism of Action

Sumatriptan how does it work involves targeting specific receptors in the brain. Its primary action is on serotonin (5-HT) receptors, particularly the 5-HT1B and 5-HT1D subtypes.

Step-by-Step Process

  1. Binding to Serotonin Receptors: Sumatriptan binds selectively to 5-HT1B and 5-HT1D receptors located on blood vessels and nerve endings in the brain.
  2. Vasoconstriction: Activation of these receptors causes constriction of dilated cranial blood vessels, which are believed to play a role in migraine pain.
  3. Inhibition of Neurotransmitter Release: The drug also inhibits the release of pro-inflammatory neuropeptides like calcitonin gene-related peptide (CGRP), reducing inflammation and pain signaling.
  4. Blocking Pain Pathways: By modulating neural activity in pain pathways, sumatriptan lessens migraine severity and duration.
